General Information

History and Forms of the Game:

A number of card games similar to whist can be traced all the way back to the early 16th century. They were all trick-taking games with a variety of minor variations. Whist became the dominant form, and enjoyed a loyal following for centuries.

The first game known as bridge was created by the twin innovations of exposing one hand during play and allowing the dealer to choose a trump suit. (According to the Oxford English Dictionary, the word bridge is the English pronunciation of biritch, an older name of the game of unknown Middle Eastern origin; the oldest known rule book, from 1886, calls it "Biritch, or Russian Whist". The Official Encyclopedia of Bridge (OED) reports speculation that the word may come from a Turkish term bir-üç, or "one-three", supposedly referring to the one exposed and three concealed hands.) This game, known today by the retronyms bridge-whist and straight bridge, became popular in the United States and the UK in the 1890s.

In 1904, the practice caught hold of using an auction phase to determine which player would designate the trump suit and have the privilege of playing with his partner's hand exposed. This variation was known as auction bridge.

The modern game of contract bridge was the result of innovations to auction bridge made by Harold Stirling Vanderbilt and others. Vanderbilt wrote down his rules in 1925, and within a few years contract bridge had become the dominant form of the game. It has supplanted all other forms of the game, including auction bridge, so that "bridge" is now synonymous with "contract bridge".

The basic form of contract bridge retains from its predecessor games, all the way back to whist, the fact that four players compete, two against two, until one side has won two games. The resulting unit is called a rubber and hence this form of play is commonly known by the retronym "rubber bridge". For those who dislike its indefinite duration, there is also a variant called four-deal bridge or Chicago.

In duplicate bridge, on the other hand, eight or more players compete at a time (most often in pairs, sometimes in teams of four or as individuals), normally playing a pre-set number of deals. In duplicate, the same deals are played more than once, and players win by outscoring their competitors with the same cards. This is implemented by placing the played cards in a container with four compartments, called a board, and passing it on to the next table. Computer-dealt hands may be used, allowing the same deal to be played at many tables, even at multiple locations.

While there is no reliable data on the number of people who play rubber bridge at home, it is generally accepted that most serious players play duplicate. It is the only form of the game at bridge tournaments and the usual form at bridge clubs. In recent years, duplicate bridge on the Internet has also become significant. Individuals can join a game from their home (or workplace!) and need not even be in the same country as their partner or opponents.

How to Play

Contract bridge, usually known simply as Bridge, is a trick-taking card game for four players who form two partnerships, or "sides". The partners on each side sit opposite one another. Game play is in two phases: bidding and playing.

Dealing

The game is played with one complete deck of 52 cards; one player is the dealer.

In rubber bridge, after the shuffle, the dealer hands out all the cards clockwise one at a time, starting with his left-hand opponent and ending with himself. At the same time, for convenience, the dealer's partner is usually shuffling a second deck, ready for use on the following deal. The deal rotates clockwise, so the dealer's left-hand opponent will deal next.

In duplicate, one player is designated as "dealer" on each particular board, but this is only for purposes of the auction and does not affect the actual dealing. The cards may be manually shuffled and dealt as in rubber bridge, but by any player; if this is done, it happens only once at the start of a session or match. Where computer-dealt hands are used, dealing machines (which may read either the standard markings, or bar codes added to each card) may be used to assemble the hands ready to be placed in the boards. It is also common for the movement to be arranged so that none of the players play all the boards; then at the start of play, each one may be given to players who will not play it, together with a printed record of the deal, and they assemble the hands.

The auction

The dealer makes the first call, and the bidding continues clockwise until three players in rotation have passed after any call. A call is any bid, a pass, a double or a redouble. (However, the word "bid" is often used informally in place of "call".)

When a player has the turn to bid, he may do any one of the following:

1. Make a new bid,
2. Pass,
3. Double if the last preceding bid was made by the opponents, or
4. Redouble a bid that has been doubled by the opponent.

A bid must include a number of odd tricks (from one to seven) and a denomination. Odd tricks are the tricks that a partnership proposes to take in excess of six (known as book). A denomination is any suit or notrump specified in a bid.

Each bid must supersede the last preceding bid by naming a greater number of tricks in any denomination, or by naming the same number of tricks in a higher ranking denomination. The rank of the denominations in descending order is notrump, spades, hearts, diamonds and clubs.

The auction ends when there have been three passes following a bid (or double or redouble). The last bid becomes the contract. The player in the partnership that made this final bid who first bid the denomination of that bid (suit or notrump) will be the declarer.

When, in a deal, all four players have passed without there being a bid, the deal is scored as a zero and the cards are passed on to the next dealer.

The play of the hand

The player from the pair that won the bidding (that is, the pair that is going to play the contract), who was the first to make a bid in the suit of the final contract (who is thus either the player bidding the final contract or his partner), is called the declarer. His partner is called the dummy.

Play to the first trick starts with the player to the left of the declarer. After the first card has been played, the dummy lays his cards open on the table. These cards are from then on played by the declarer, who tells the dummy which card is to be played whenever it is the dummy's turn to play on a trick.

Apart from this, the play is just like other trick-taking games - the player who took the previous trick leads to the next one (if the declarer took the trick in dummy, he has to play from dummy on the next trick, if he took the trick in his own hand, he has to play from his own hand). Whether there is a trump suit, and if so, which suit it is, has been decided during bidding.

During the play, each player must follow suit--that is, play the same suit as that led. If a player cannot follow suit (has no more cards of the suit led), he may discard a card of another suit, or, in a suit contract, play a trump. Trumping is optional. Failure to follow suit can result in penalties for a 'revoke.' The player who contributes the highest card from the lead suit wins, except that if any player plays a trump, the highest trump card wins.

Duplicate Bridge

Like all other card games, the score in bridge depends on one's cards. To diminish this effect, and increase the element of skill, in clubs and tournaments one's score is not looked at on its own, but compared to that of others who played the same deals. There are two major systems: Pairs and teams games.

With Pairs games, two person teams (pairs) compete. Depending on the rotation, the pairs may be grouped as 'North/South' and 'East/West' or may rotate between north/south and east/west seating. In each case, a team receives a point for each team they beat and half a point for each team they tie. At the end of the session, points are added and the team with the highest point total is the winning team. Only half the teams (or less) will play any particular hand (the other half will play the opposing hands in the four-hand deal).

With team games, four-person teams divide into pairs. A 'North/South' pair plays the 'East/West' pairs from the other team(s). The 'East/West' pair plays the 'North/South' pair of the opposing team(s). At the end of team play, teams compare their overall scores.

Scoring - Rubber Bridge

In friendly play, one generally plays rubber bridge. In rubber bridge, extra points are scored for winning a rubber, which means getting to a game (100 points) twice. There are two types of points: Points below the line and points above the line. Only points below the line count towards a game.

Score for making

If the declarer makes his contract, the number bid, multiplied by a suit-dependent multiplier, is scored below the line. Any overtricks, again multiplied by the suit-dependent multiplier, are scored above the line.

The multiplier is 20 for clubs and diamond (the minor suits), and 30 for hearts and spades (the major suits). For No Trump, the multiplier is also 30, but with an added 10 points below the line for the first trick (made) only.

Examples:

• bid: 2 clubs, made 9 tricks: 40 (2×20) points below, 20 (1×20) above the line.
• bid: 4 hearts, made 10 tricks: 120 (4×30) points below, 0 (0×30) above the line.
• bid: 4 no trump, made 11 tricks: 130 (4×30+10) points below, 30 (1×30) above the line.

Game and rubber

If the score of a partnership below the line equals or exceeds 100 points (either at once or taken together with what already was below the line), the partnership is said to have scored a game, and all scores below the line are turned into scores above the line. Thus making game takes five tricks in a minor suit, four in a major suit, or three in No Trump (or some combination of partial scores).

The first partnership that wins two games wins the rubber. They score a 700 point bonus if they won in two games, or 500 points if their opponents also made a game.

Vulnerability and slam bonus

A partnership that has already made a game is called vulnerable, which is of importance for the slam bonus and for the downtricks.

If a player bids and makes a contract of 6 in something (i.e. wins all but one trick), he is said to have made a small slam. This gives a bonus (above the line) of 500 points when not vulnerable, and 750 points when vulnerable. If a player bids and makes a contract of 7 in something (thus scoring all the tricks), he is said to have made a grand slam. This gives a bonus of 1000 points when not vulnerable, and 1500 points when vulnerable.

Undertricks

If a pair fails to achieve their contract, they 'go down'. In such cases, their opponents score points above the line. If the pair is not vulnerable, their opponents get 50 points per undertrick, if it is vulnerable 100 points per undertrick.

Doubled

If a pair is doubled, and makes their contract, they get double points for all tricks bid (below the line), while overtricks score extra - 100 points per overtrick if not vulnerable, 200 points if vulnerable (above the line). Furthermore, the pair gets 50 points bonus (above the line) 'for the insult'. All these values are doubled again if the contract was redoubled. The slam bonuses are not influenced by a double, nor are the rubber bonuses - although the latter are of course influenced by the fact that there are more scores below the line, and thus games are reached faster.

If a pair is doubled and goes down, the penalty (points to the other pair) are as follows:

• If the pair is not vulnerable, 100 for the first downtrick, 200 for the second and third, and 300 for each subsequent downtrick.
• If the pair is vulnerable, 200 for the first downtrick, and 300 for each following one.

These scores are also doubled again if the contract was redoubled.

Footnote - Recent scoring changes

If you read old Bridge books, you may notice some differences in the scoring rules.

The undertrick penalty when doubled, not vulnerable, used to be 100 for the first undertrick and 200 for each subsequent. This was changed because it was too easy to sacrifice against a grand slam. A vulnerable grand slam is worth 1500 (slam bonus) + 500 (game bonus) + 210 (major suit trick score) = 2210. Down 11, doubled not vulnerable, used to be 2100, a profitable sacrifice.

Also, the "insult bonus" for making a redoubled contract used to be only 50. This was changed to 100, so that playing 5 of a minor, redoubled, making an overtrick, is always worth more than an undoubled small slam.

Scoring - Duplicate Bridge

In duplicate bridge, which is what is normally played in a club or tournament, each hand is scored by itself, and not as part of a rubber. This changes (and simplifies) the scoring as described above.

In duplicate bridge, if the required number of tricks for the contract has been made, the pair gets a number of points for the tricks bid and the overtricks as described above (20 per trick above the book of six tricks in clubs/diamonds, 30 per trick in hearts/spades, 30 per trick plus 10 bonus in No Trump, possibly doubled or redoubled). If the number actually bid is enough to score 100 points or more, a game has been made, which scores 300 when not vulnerable and 500 when vulnerable. If it is lower, the score is not carried over to the next hand, but there is a 'part score' bonus of 50 points.

The bonus for slam, the bonus 'for the insult' and the scores for downtricks and doubled overtricks are the same as described above.

In duplicate bridge, in every series of four deals, the vulnerabilities of 'all vulnerable', 'none vulnerable', 'vulnerable against not vulnerable' and 'not vulnerable against vulnerable' will all occur once, in a predetermined order.

• Bidding box

In tournaments, "bidding boxes" are frequently used. A bidding box is a box of cards, each bearing the name of one of the legal calls in bridge. A player wishing to make a call displays the appropriate card from the box, rather than making a verbal declaration. This prevents unauthorized information from being conveyed via voice inflection. In top national and international events, "bidding screens" are used. These are diagonal screens which are placed across the table, preventing a player from seeing his partner during the game.

Bidding Techniques

Before resorting to any specific technique, it is recommended to decide on a bidding system that will be used by the partnership.

Bidding systems and conventions

A pair is allowed to try to pass information about their hands, but this is restricted in two ways:

• Information may only be passed by the calls made and later by the cards played, and not by any other means.
• All information passed must be available to the opponents. At a minimum, a player must fully explain a call or play made by her partner upon being asked by an opponent. In club and tournament play, additional disclosure mechanisms including partnership convention cards and the alert procedure usually must be used.

Thus, one may have all kinds of meanings for bids, as long as they are told to the opponents. However, the meanings that one can have for various bids are sometimes restricted at tournaments.

The meaning of the various bids in a partnership are called that partnership's bidding system. A number of different bidding systems exist, such as Goren, Acol, Standard American, and Precision Club. Many experts today use a system called Two Over One (2/1).

Bids, Doubles, Redoubles, and even Passes can be either natural or conventional.

A natural suit bid is one that implies some length in the suit bid. For example, an opening bid of one spade, showing at least 5 cards in spades (and nothing about any other suit lengths), would be natural.

A conventional suit bid provides information unrelated to the suit named. For example, an opening bid of one club, showing 16 or more points, but saying nothing about how many clubs are held, would be conventional.

A natural notrump bid is one that implies a balanced distribution of cards among all suits (no particularly long suit, although many experts will bid no trump with up to five cards in one suit as long as the bidder has no singletons or voids and at most one doubleton) and a certain number of points as agreed upon by the partnership.

A conventional notrump bid says none of these things. The most common examples of conventional notrump bids are the Unusual notrump (showing length in 2 unbid suits) and the Blackwood convention.

A natural double (also called penalty) is one that implies an intent to defend and defeat the current contract.

A conventional double is one that conveys some other meaning. The most common example of a conventional double is the Takeout double of a low-level bid, implying support for the unbid suits and asking partner to choose one of them.

There are many conventions. Some of the most famous are Stayman, Jacoby transfers and Blackwood.

Hand Evaluation

The decision as to how high and what suit to bid is fundamental to the game, but broadly it will depend on how highly one values one's hand. There are a number of techniques used for this. The most basic is the Milton Work point count. This can be augmented by other guidelines such as losing trick count, law of total tricks or Zar Points (http://public.aci.on.ca/~zpetkov/TheAnnotation.html).

Bidding Systems

Each bidding system can be either very detailed or very basic. Here are three common bidding systems. Until such time as you can find adequate description of these systems here, just search for the names. There are descriptions of these systems elsewhere on the web.

1. Standard American (see also 2/1 variation)

   5 card majors, strong 1NT, min. 3 card minors, Stayman, Blackwood, take-out doubles

2. Acol (popular in the UK)

   4 card majors

3. Precision or Strong Club

   1st bid shows points, not suit. (1C=16-20pts; 1D=11-15pts)

On choosing and applying a bidding system.

If you look up Richard Pavlicek, you will see that the guy invented a bidding system No, actually he invented four bidding systems. On wait, he actually invented four flavors of one bidding system.

Suppose you and your partner decide the Richard Pavilcek's system is the best system in the world, and you want to play it. Which flavor should you choose?

Even if you do choose a flavor, you will run into several kind of mishaps:

1. Forgetting the conventions you are actually playing.
2. Bidding more or less according to the system, and bidding bad contracts (bad contracts are the ones that are below average in any competitive bridge hand)
3. You think that you partner, or you opponent play more often than you.

These three problems will arise no matter what bidding system you and your partner choose, unless you understand bidding in a deeper way, and not just by rote learning.

In order to properly understand bidding you have to first understand, really fully understand the play of the hand, both on the defender and on the declarer side.

From now on, I shall assume that you do.

You take any bridge hand, and play it double dummy. You play it in several contracts: for example 6♠ by NS, three notrump by EW/ After you play the hand several time you will realize, that playing double dummy, with competent play by declarer and defenders, some contracts can be made, and other cannot be.

Of all the NS contracts possible to make, one will get the NS partnership most points, let's suppose that this is 3H by north. The same goes for EW, let's suppose that their optimal contract is 3S. the proper result for this hand is 3♠ by EW.

That means that any good bidding system should lead EW to 3♠, or a better result. Ho do we accomplish this? that takes some doing, but for now, just make sure you get yo the proper results, if you do not, ask yourself why not.

Playing Techniques

Techniques as declarer

Techniques in the play of the hand

Terence Reese, a prolific author of bridge books, points out that there are only four ways of taking a trick, and two of these are very easy

• playing a high card that no one else can beat
• trumping an opponent's card
• establishing long cards (the last cards in a suit will take tricks if the opponents don't have the suit and are unable to trump)
• playing for the opponents' high cards to be in a particular position (if their ace is in front of your king, your king may take a trick)

All trick-taking techniques in bridge can be reduced to one of these four methods.

The optimum play of the cards can require much thought and experience, and is too complicated to describe in a short article. However, some basic ideas of probability may be considered:

Some of the most important probabilities have to do with the position of high cards.

• The probability that a given opponent holds one particular card, e.g. the king: 50%
• The probability that a given opponent holds two particular cards, e.g. the king and the queen: approximately 25%
• The probability that a given opponent holds at least one of two particular cards, e.g. the king or the queen: approximately 75%

When developing long cards, it is important to know the likelihood that the opponents' cards in the suit are evenly divided between them. Generally speaking, if they hold an even number of cards, they are unlikely to be exactly divided; if the opponents have an odd number in the suit, the cards will probably be divided as evenly as possible. For example, if declarer and dummy have eight trumps between them, the opponents' trumps are probably (68% chance) divided 3-2 (one opponent with three trumps, the other with two) and trumps can be drawn in three rounds. If declarer is trying to play with a seven card trump suit, it is more likely that the outstanding trumps are divided 4-2 (48%) than that the cards are evenly divided 3-3 between the opponents (36%).

Basic techniques by declarer

When new to the game, a player should be familiar with these strategies for playing the hand:

• trumping
• crossruff
• establishing long suits
• finesse
• General suit management
• holdup (mostly at NT contracts)
• managing entries
• when to draw trumps

Drawing trumps

When playing as declarer in a trump contract, you should hopefully have chosen a trump suit in which you have the majority of the trumps—ideally 8 or more trumps between your two hands. Even so, your opponents will have at least some trumps between them, and they can disrupt your contract by ruffing cards you were hoping to win. It's therefore often wise to lead trumps for a few rounds early in the hand. Since your opponents are forced to follow suit, you can exhaust them of trumps and play the rest of the hand safe from being ruffed. This is called drawing trumps.

Drawing trumps prevents you from losing otherwise winning cards that get ruffed by your opponents, but it also exhausts your own trumps, which means you can't use them for ruffing. The key question is to look at the length of the trump suits in your two hands: you can generally reckon to score one trick for each trump in the hand with the longer trump suit (minus any missing trump honors). However, if you draw trumps then the trumps in the hand with the shorter trump suit don't score, since they have to be used to follow the led suit. If instead you lead a card from one hand in which the other is void, you can use the short trump suit for ruffing, gaining extra tricks.

In general you will want to draw trumps as soon as you can, unless you can see a specific reason not to. Good reasons to delay drawing trumps are:

• You need to score extra trump tricks by using the trumps in the hand with the shorter trump suit to ruff.
• You need to use trumps to provide extra entries to one of the hands (usually dummy)
• You need to discard losing cards quickly.

The finesse

If you have all the top cards in a suit, you can make them score however you play them (provided your opponents are unable to ruff). If you hold the Ace and Queen and your opponents have the King, it may seem like you can't make two tricks with them. However, if you lead correctly you can score with the queen 50% of the time.

Suppose you are declarer (South) and dummy (North) has AQ♥. If you play the ace then the queen, the opponent holding the king will take the trick (unless the king is singleton). On the other hand, if you lead a low heart from your hand (South), then you may be able to win the queen. Suppose West holds the king. If West plays the king on your low heart, you play the ace and the queen is a guaranteed winner in the next round. If West doesn't play the king, you play the queen and win it. Of course, if the king lies with East then things won't work out so well. You'll play the queen and lose.

This is the basic concept of a finesse. Note that whether the finesse works depends entirely on which hand holds the missing card. Once you play for the finesse, there's nothing your opponents can do about it if West holds the king, and nothing you can do to win if East holds the king.

How do you know whether to play a finesse? Occasionally there will be a clue in the bidding (say East has already shown he has ace and king in another suit, but his bidding rules out him having 10 points or more). More often though, it's a straight 50% gamble.

Even if you can't tell whether a finesse is going to win you a trick, it often pays to consider how bad the situation will be if the finesse doesn't work out and you lose the lead. Often there is one defender that represents more of a threat than the other, perhaps because they have a suit with lots of winners that the other opponent is void in and can't lead. A finesse into the "safe" hand will lose at most a single trick, while a finesse into the "danger" hand might lose three or four.

The hold up

Suppose your opponents hold strength in a particular suit and you're worried that they can make enough tricks in that suit to defeat your contract. In such a situation, it's often to your advantage to deliberately lose one or two tricks in the suit before you play a winner. Hopefully this means that one defender will have no more cards in this suit, so if they get the lead later on they can't make any tricks: though their partner has winners, they can't lead to them.

Suppose spades are trumps, and you have the following hearts:

	T87♥
92♥		KQ3♥
	AJ654♥

West leads the 9♥ (top of a doubleton), East playing the Queen. You win with your Ace. If West regains the lead before you've drawn all the trumps (for example, by playing the A♠), West will be able to play the 2♥ to East's King. East can then return the 3♥ for West to ruff. Two heart tricks have been lost.

If instead of playing the Ace on the first round you duck, East will return a K♥ that you can win. It doesn't matter if West later gains the lead, since the third round of hearts can only be ruffed if it is led by East.

Advanced techniques by declarer

Someone who plays regularly in tournaments should be familiar with these concepts:

• counting the hand (tracking the distribution of suits and high cards in the opponents' hands using inferences from the bidding and play)
• coups and elimination
• duck
• dummy reversal
• endplay
• safety play
• squeezes

Techniques as defender

Basic techniques by defenders

• opening lead
• when to lead trump
• suit management
• discarding

Advanced techniques by defenders

• avoiding an endplay or squeeze
• counting the hand (tracking the distribution of suits and high cards in the unseen hands using inferences from the bidding and play)
• opening lead - using information from auction
• signaling
• uppercut

The best explanation for various bridge playing techniques, is to first explain a playing technique, as used by the declareer, and then explaining a defender technique used to thwart that particular declarer technique.

The most basic technique is using long suits.

Suppose you are playing 3NT and you are holding the following two hands:

Dummy: ♠AKQxxx ♥xxx ♦xxx ♣A

Declarer: ♠Jx ♥KQJ ♦KQJ ♣xxxxx

West starts by cashing his heart and diamond aces. He now plays another heart, and you have to plan the play. You can immediately see two heart tricks, and two diamond tricks, no matter what you chose to discard on west's two aces (you probably discarded the two jacks, which is not always optimal, but that's deception, so we shall deal with it later, for this hand, it makes no difference.)

So, counting four tricks is good. you can also see another four in dummy, so that's almost the nine you need. Where are you going to get more tricks from?

Let's see. there are only thirteen spades, and you are holding eight of them. that means that you opponent are holding only five. Chances are they are divided 3-2 between the two of them. but you can make you contract even if they are divided 4-1, providing that you play carefully enough. you should cash all your hearts and diamonds from the declarer hnd, than cash the spade jack, which would hold the trick. You then play a small spade to the AKQxx left in dummy. You play the high cards first, and unless you are very unfortunate, the low spades will take tricks too. the opponents will have no spades left by that stage. Oh, don't forget to take the club ace too. You will end up with two overtricks.

Bidding Systems

A bidding system is a collection of conventional agreements to be used. A system should cover all frequent bidding sequences, including all opening bids, responses to opening bids and all overcalls.

Classification

• A natural is green
• A system using 1♣ or 1♦ as artificial strong opening (usually showing 15/16/17 or more HCP) is blue
• A system that contains a convention that falls into the highly unusual method category is yellow(HUM)
• A system that does not fall into the above 3 categories is red

Glossary

0–9

2-under Preempts

A 2 or 3-level conventional opening bid made two steps below the opener's suit: for example, 2♦ to show a weak two bid in spades or 3♣ to show a three-level preempt in hearts. If 2♣ is a strong, artificial force, 2♥ is natural.

1430, or 1430 RKCB

A mnemonic for a variant response structure to the Roman Key Card Blackwood convention. It represents "1 or 4" and "3 or 0", meaning that the lowest step response (5♣) to the 4NT key card asking bid shows responder has one or four keycards and the next step (5♦) shows three or zero.

0314, 3014, or 3014 RKCB

A mnemonic for the original (Roman) response structure to the Roman Key Card Blackwood convention. It represents "3 or 0" and "1 or 4", meaning that the lowest step response (5♣) to the 4NT key card asking bid shows responder has three or zero keycards and the next step (5♦) shows one or four.

A

Rubber Bridge Scoring

Above the line

In rubber bridge, the location on the scorepad above the main horizontal line where extra points are entered; extra points are those awarded for holding honor cards in trumps, for bonuses for scoring game, small slam, grand slam or winning a rubber, for overtricks on the declaring side and for undertricks on the defending side and for fulfilling doubled or redoubled contracts. Points awarded for contract tricks bid and made are entered below the line.

ACBL

American Contract Bridge League

Acol

An approach-forcing, natural bidding system, based on a weak NT and 4 card majors, popular in the United Kingdom and the Commonwealth.

Active

1) An approach to defending a hand that emphasizes quickly setting up winners and taking tricks. Contrast passive.

2) An approach to competitive bidding that emphasizes frequent interference with opponents' bidding sequences.

Adjusted score

In duplicate bridge, a score that penalizes a pair or team that has committed an irregularity, and/or compensates a pair or team that has been damaged by an irregularity. The penalty and the compensation need not be commensurate.

Advance cue bid

The cue bid of a first round control that occurs before a partnership has agreed on a strain.

Advance sacrifice

A sacrifice bid made before the opponents have had an opportunity to determine their optimum contract. For example: 1♦ - (1♠) - Dbl - (5♠).

Advancer

Overcaller's partner, especially one who bids following the overcall.

Adverse vulnerability

Vulnerable vs. non-vulnerable. Also called "unfavorable vulnerability."

Aggregate scoring

Deciding the outcome of a contest by totaling the raw points gained or lost on each deal. Also called "total point scoring."

Agree

For a partnership to come to a decision, explicitly, conventionally or by implication, on the denomination in which to play a hand.

Agreement

An understanding between partners as to the meaning of a particular call or defensive play. There are two types of call agreements: (1) when the call is natural, the agreement is said to be a treatment, and (2) when the call is artificial, the agreement is said to be a convention.

Air, on

Template:BridgeSuitRight

To win a trick with a high card while capturing only small cards - normally said of a defensive play. In the example at right, when South leads the ♥8, West must take the ♥A on air, or risk making no heart tricks. Nevertheless, best defense on a given hand may call either for ducking the winner or for playing it on air.

Alcatraz coup

Declarer's intentional and unethical attempt to locate a finessable card by revoking. If the play is unintentional, it is nevertheless subject to score adjustment.

Alert

A method of informing the opponents that partner's bid carries a meaning that they might not expect; alerts are regulated by sponsoring organizations such as the ACBL and the EBU, and by individual clubs or organisers of events. Any method of alerting may be authorised including saying "Alert", displaying an Alert card from a bidding box or 'knocking' on the table.

Announcement

An explanatory statement made by the partner of the player who has just made a call that is based on a partnership understanding. The purpose of an announcement is similar to that of an Alert. It is made following calls whose meanings are not unusual, but which different partnerships treat differently. In the ACBL, common announcements include "Transfer" for a direct transfer bid, the point range for an opening bid of one notrump, and "Forcing" or "Semi-forcing" for a 1NT response to a major suit opening bid. The sponsoring organization specifies which calls should be announced.

Antipositional

A call is antipositional if it tends to make the "wrong" partner the declarer. If West opens the bidding, it may be best for South to declare a North-South contract, so that West will have to play from his high cards on opening lead. This positioning may protect South's tenaces. In that case, a call that will make North declarer is antipositional. See wrongside.

Appeal

In tournaments, to appeal is to request that a committee review a ruling made by a director.

Approach-forcing

A principle, first used in the Culbertson system, that has survived in modern bidding. The original idea was to abandon the indiscriminate notrump bids that characterized auction bridge in favor of a slower exchange of information via suit bidding.

Arrow

A marker, usually a large card with an arrow on it, that shows which direction is treated as North at a table in a duplicate event.

Arrow switch

The action of changing the North direction during an event, typically for the last round of a Mitchell movement, so that the pairs who were North-South become East-West and vice versa. This allows a single winning pair to be determined.

Artificial

1) A call that is not natural which by agreement carries a coded meaning not necessarily related to the call's (or to the prior call's) denomination.

2) A bidding system that contains many such calls.

Asking bid

A bid that, by prior agreement, requests information about a feature of partner's hand: for example, number of controls, suit length, or control of a particular suit.

Attacking lead

A lead that instigates an active defense; often, the lead of an honor from a sequence, or a forcing defense.

Attitude

A defender's desire, or lack thereof, for his side to continue playing a suit. By means of signals, defender encourages or discourages the continuation of the suit.

Autobridge, a device for learning bridge

Auction

1) See bidding.

2) Auction bridge, an older form of bridge, replaced by Contract bridge.

Autobridge

A mechanical game device consisting of a set of printed deal sheets and a viewing template used to learn bridge by oneself. (see image).

Automatic squeeze

A squeeze position that succeeds against either opponent. Contrast with positional squeeze.

Average

1) In matchpoint scoring, one-half the matchpoints available on a given deal.

2) An average score is sometimes awarded to both pairs when for some reason they cannot complete the board. If neither pair is at fault or both pairs are at fault, the director may decide to award average to each side. Law 12.C.2 of the Laws of Duplicate Contract Bridge states that if one pair is at fault, it receives an average-minus (at most, 40% of the available matchpoints on the board). A pair not at all at fault receives average-plus: 60% of the available matchpoints on the board, or, if greater, the average of the matchpoints the pair earned on other boards played during the session. The assigned scores need not sum to the total available matchpoints.

3) Also see IMP pairs, where "average" refers to the datum used in scoring.

Avoidance play

A play designed to keep a particular defender off lead, often to prevent the lead of a suit through a tenace position in either declarer's hand or dummy.

B

Back in

To make a partnership's first bid, having previously passed. For example, in 1♥ - (P) - 1NT - (P); 2♣ - (Dbl), the doubler has backed into the bidding.

Backward finesse

A combination of two finesses in a suit such that the first finesse is "backward" (that is, the reverse of the normal direction).

Balance

To keep the bidding open when it is about to be passed out at a low level. For example, if the bidding goes 1♥ - (P) - P - (1NT), the 1NT bid is a balancing action. The balancing bid is often made with a hand of substandard strength in order to prevent the opponents from securing a low-level contract.

Balanced distribution

1) Narrowly, balanced distribution of a hand or suit is 4-3-3-3, 4-4-3-2 or 5-3-3-2. Equivalently, there are no voids, no singletons, and at most one doubleton.

2) Balanced is commonly used in a broad sense that includes semi-balanced. Broadly, balanced distribution permits no void, singleton, or 7-card suit.

Balanced hand

A 13-card hand with balanced distribution in the narrow or wide sense just above. On the first round of bidding, natural notrump bids generally denote balanced hands.

BAM

Board-a-match, one method of scoring a duplicate bridge session or tournament.

Bar

To prevent a player from making a bid, either by a penalty caused by an irregularity, or because partnership agreement requires a pass in a given situation. In either case, the player is said to be "barred."

Barometer scoring

In a duplicate event, the posting of contestants' running scores after each round. Knowledge of the current standings often adds excitement to the contest, and can affect the strategies adopted by those in a position to win the event.

Bath coup

A holdup by declarer, to prevent an opponent from continuing a suit. In the classic position, declarer holds ♠AJ2 and West leads ♠K from ♠KQ1098. By playing the 2 on West's K, South makes it impossible for West to continue spades without giving South a free finesse.

Beer Card

The ♦7.

Below the line

In rubber bridge, the location on the scorepad below the main horizontal line where points awarded for a successful contract, i.e. tricks bid for and taken exclusive of bonus points, are recorded. These are the points counted towards game. See Above the line.

Bermuda Bowl

The cup awarded to the winner of the international team championship, the most prestigious award in bridge. Also, the championship contest itself.

Bid

A specification of both level and denomination or strain, such as three notrump or four hearts. While any legal bid constitutes a potential contract, some bids carry special coded meanings when used by the partnership as a conventional bid and as such are not normally intended as a potential contract.

Bid out of turn

A bid erroneously made when it was another player's turn to bid. Subject to penalty.

Biddable suit

A suit that a partnership regards as long and strong enough to be bid. Partnerships often employ different standards of length and strength for suits named in opening bids, in responses, in rebids and in overcalls.

Bidding

The first stage of a deal, when players jointly determine the final contract. Having examined their own cards, they make a series of calls in rotation, which is called the auction or the bidding.

Bidding box

A box, placed on the table, that contains cards with calls printed on them. By selecting and displaying a card, a player can make a call without speaking. Silent bidding removes one source of unauthorized information from the game.

Bidding space

The number of steps available in an auction (see Useful space principle), or the number of steps consumed by a bid. The sequence 1♣ - 1♦ consumes only one step, whereas 1♦ - 2♣ consumes four steps. Because alternative bids are skipped, it often happens that the more steps a bid takes up, the more specific meaning it carries.

Bidding system

The complete set of agreements and understandings assigned to calls and sequences of calls used by a partnership, including a full description of the meaning of each treatment and convention.

Blackwood convention

Popular bidding convention in contract bridge, used to determine number of partner's aces/kings to evaluate for slam bids.

Blank

1) (Adjective) Unprotected by other, usually lower cards in the same suit: "I held the blank king of spades."

2) (Verb) To discard in such a way as to leave a card unprotected: "She blanked the king of spades."

Blitz

(Slang) A win by the widest possible margin.

Blocked

(Adjective) If a suit is divided between partners in such a way that the hand with the shorter holding has only high cards, the suit cannot be run without an entry to the longer holding in another suit; it is then said to be blocked. If North holds ♦AK and South holds ♦QJ10, South cannot cash a third diamond trick without an entry in another suit. The diamonds are blocked until North is able to unblock by playing the ace and king.

Board

1) One particular allocation of 52 cards to the four players including the bidding, the play of the cards and the scoring based on those cards. Also called deal or hand.

2) A device that keeps each player's cards separate for duplicate bridge.

3) The dummy's hand. For example, "You're on the board", means "The lead is in the dummy."

Board-a-match

A form of scoring for teams, analogous to matchpoint scoring for pairs. A team earns 1 point if its pairs score higher than the opposing pairs (with the same cards at the other table), 1/2 for equal scores, and 0 for lower scores. Board-a-match scoring is now less common than IMP scoring, or IMPs victory points in a Swiss tournament.

Body

Intermediate cards such as the 9, 8 and 7, that contribute to a suit's trick-taking potential.

Bonus

In bridge scoring, beyond points for bid tricks taken, which are awarded for making a contract, the additional points awarded for making a doubled contract, or for making doubled or redoubled overtricks. There are different bonus amounts at the partscore, game, small slam, and grand slam levels. The size of most bonuses depends on the vulnerability. Bonus amounts are different in rubber bridge and duplicate bridge.

Book

1) (Noun) The basic six tricks that must be taken by the declaring side. The first six "book" tricks are always assumed and are not taken into account in bidding or scoring. Thus, a contract at the 1-level commits declarer to take at least 7 (that is, 6 + 1) tricks, and provides trick points only for the trick above book. The term apparently originated from the whist practice of arranging the first six tricks into a stack called a "book."

2) (Noun) The number of tricks that the defensive side must take so as to hold declarer to his contract. If the contract is 4♠, defenders' book is 3.

3) (Verb, usually passive) Slang. As declarer, to have lost the maximum number of tricks without being set. At 4♠, declarer is "booked" when he has lost three tricks.

Bottom

At matchpoint scoring, the lowest possible score on a board. Also, zero.

Bracket

A group of entries in a tournament that will eventually have one winner. The grouping is often done on the basis of masterpoints.

Break

1) (Noun) The distribution of cards in a suit between two (often unseen) hands: "I got a 4-1 spade break." An even break occurs when the cards are distributed evenly or nearly so, such as 3-3 or 4-2. A bad break, connoting a distribution that is difficult to handle, suggests an unexpectedly uneven distribution, such as 5-1 or 6-0. See distribution.

2) (Verb) To be divided between two hands. "The spades broke 3-2."

3) (Verb) To lead a particular suit for the first time during a particular deal.

4) (Verb) Slang. To play for and find a particular distribution, usually the most favorable. "I broke the spades."

Bridge maxims

A compilation of short "laws", "rules" and rules-of-thumb advice; often, not always, valid.

Bridge World, The (TBW)

Broken sequence

A sequence of honor cards, one or more of which is missing, for example AQJ.

Bullet

(slang) An ace.

Business double

A penalty double. Contrast with various competitive and informatory doubles such as takeout double and negative double.

Bust

(Slang) A very weak hand. Sometimes paired with the name of a long suit: for example, "club bust" to denote a hand with long clubs and very little high card strength. See also Yarborough.

Busy

A card that is needed for some purpose is said to be busy. For example, cards that a defender is trying to preserve while declarer executes a squeeze are "busy." Contrast with idle.

Butler

A method of overall scoring in duplicate bridge where every result is subtracted from a datum (average or median) score and converted to IMPs using a table defined by the WBF.

Bye

1) A round of an event during which a team or pair is not scheduled to play.

2) A location, such as a chair or stand, where boards are kept when not in use during an event.

C

Caddy

A non-playing person designated to move boards between tables during a tournament, collect score slips, etc.

Calcutta

1) See Cross-IMP scoring

2) A tournament in which bettors bid on participating pairs or teams. The proceeds from the auction are distributed partly as prizes to the top finishers, partly to the bettors who successfully bid on them. A pair or team can typically buy an interest in itself.

Call

Any bid, pass, double, or redouble in the bidding stage.

Canapé

An approach to bidding in which a player bids his shorter suit prior to his longer suit. A feature of the Blue Team Club and the Roman Club.

Captain

1) In teams competition one person, called captain in the rules, must represent a team in stipulated official settings and to make stipulated official decisions for a team. A playing captain (pc) is eligible to participate as a player at the table; a non-playing captain (npc) may not. World championship teams are limited to six players, thus to six or seven members depending on the kind of captain. Other team officials such as a coach are not team members and not covered in the rules of bridge.

2) The partner who makes the decision for a partnership in certain bidding situations, such as ace-asking sequences.

Card reading

The act of determining the distribution of cards in unseen hands, and the location of high cards therein, by analyzing the bidding, play and other clues.

Carding

The defensive signaling used by a partnership.

Carryover

In a complex event, some participants begin a later stage with scores that depend on performance in an earlier stage. Simple accumulation of scores from stage to stage is full carryover but the term is commonly used only when carryover is less than full.

Some team events have a later knockout stage with carryover equal to some fraction of any margin of victory from an early-stage match between the same teams.

Many tournaments for teams, pairs, or individuals have stages that progressively reduce the field, such as by cutting the bottom half at the end of each day. Sometimes the qualifiers continue with a fraction of their qualifying margins as carryover, which effectively gives weight less than one to points scored in the earlier, larger, lower-quality field. Sometimes there is no carryover; comfortable and borderline qualification are equivalent in the next stage.

Cash

To take a trick with a card that is currently the highest in the suit, thought likely to succeed, or to take all available winners in a suit.

Cavendish variation

A version of Chicago, with dealer's side not vulnerable on the second and third hands, as in the standard version.

CBF

Canadian Bridge Federation.

Change of suit

A bid in a new suit, as 1♠ in the sequence 1♦ - 1♥; 1♠.

Chicago

A form of bridge in which a rubber is completed every four deals, and the vulnerability is different in each of those deals (dealer's side is vulnerable on the second and third deals). The scoring and sequence of dealer and vulnerability used in duplicate bridge are derived from those used in Chicago bridge. Chicago is said to have been devised by commuters who played bridge on daily train journeys, where the time available for play was limited by the length of the trip.

Chicane

A hand without any trumps.

CHO

Centre-hand opponent (slang), a derogatory or facetious term for one's partner, or partners generally. Compare LHO and RHO, left- and right-hand opponents.

Chunky

A suit with enough honor strength to play well unaided by partner's cards (but not solid) is chunky. Normally said of four-card suits. AQJ10 is a chunky suit; AQ96 is not chunky.

Claim

A statement by declarer about how the remaining unplayed tricks will be won or lost. Normally the claiming player exposes his hand and describes the sequence of play for the remaining tricks (but such plays as finesses, unless already proven, are disallowed). A claim is best made only when the play of the rest of the hand is obvious. Claims are often inadvisable: apart from the possibility of a mistaken analysis, it can take longer to explain the line of play than to play it. See also concession.

Clear a suit

Knock out an opponent's high-card control of a suit, or unblock one's own high cards.

Closed hand

Declarer's hand (as distinct from the dummy, which is faced or open).

Closed room

In a team match, a room where two of the pairs compete, and in which spectators are not allowed.

Coffeehousing

Making improper remarks to mislead the opponents, or asking improper questions designed to suggest a defensive play.

Cold

A contract that a player cannot fail to make, even against the best defense, is cold.

Combination

1) See suit combination.

2) finesse.

Combination play

A line of play that offers more than one chance to take additional tricks: for example, playing to drop an honor in a longer suit and then finessing for an honor in a shorter suit.

Come-on

A defensive signal that encourages partner to continue a suit, usually by means of the rank of the card used to follow suit.

Comic notrump

A notrump overcall that shows a weak hand with a long suit, to which the overcaller can escape if doubled. Also known as Gardener 1NT.

Communication

1) The placement of the lead in one or the other of the two partnership hands, so as to make a subsequent lead from the more advantageous hand, specifically the ability to place the lead in such hand.

2) The means of conveying a message to partner via the bidding and by the card played to a trick. The only legal means of communication is through the calls and plays themselves, rather than through mannerisms such as tone of voice and hesitations. Often generalized as communications in both senses.

Comparative scoring

The method of scoring used in matchpoint or Board-a-Match events. The metric used is not the number of points earned on a particular deal, as it is when using quantitative scoring, but the number of pairs that have been out-scored.

Competitive auction

A bidding sequence which involves both partnerships. Also, competitive bidding.

Concession

A statement by a player as to the number of remaining tricks that he must lose. (See claim.)

Condone

To act after an opponent's irregularity without arranging for the penalty specified in the Laws to be applied.

Congratulatory jack

The unnecessary play (by follow-suit or by discard) of a jack following partner's exceptionally successful action. More often used by the defense, but possible as a play from dummy.

Constructive

1) Bidding that is aimed at reaching a side's optimum contract, as distinct from calls intended to interfere with the opponents' bidding.

2) Constructive raise: by partnership agreement, a single raise of a major suit opening that shows more strength than usual.

Contract

1) The statement of the pair who has won the bidding, that they will take at least the given number of tricks. The contract consists of two components: the level, stating the number of tricks to be taken (in addition to the book tricks), and the denomination, denoting the trump suit (or its absence in a notrump bid). The last bid in the bidding phase denotes the final contract.

2) Short for Contract bridge in contrast to Auction bridge (auction) and other card games in the family.

Control

1) A feature of a hand which prevents the defenders from taking sufficient immediate tricks in a specific suit so as to set the contract or make the setting of the contract unavoidable. Aces are termed "first-round" controls and kings are termed "second-round" controls. In trump contracts, voids are also considered first-round controls and singletons second-round controls.

2) (Said of trump contracts) Declarer's ability to manage the trump suit successfully. To lose control usually means being forced to shorten one's trumps so much that the opponents can subsequently control the play of the hand.

An equivalent or similar term is stoppers.

Control-bid

A bid that shows control of a particular suit. Often a cue bid, but not all cue bids are control-bids.

Convenient club

See Short club.

Convention

1) An agreement between partners on an artificial meaning of a call or sequence of calls, which is not necessarily related to the length and strength of bid suits or of willingness to play in notrump. Many bidding conventions are artificial.

2) An agreement that a particular defensive play has a special meaning.

Compare with Treatment.

Convention card

A form filled out by a partnership that shows the bidding and play conventions they are using. Normally used during tournaments.

Convert

To change the effect of a call. For example, passing partner's overcall of 2♦ when playing Michaels cue bids converts the overcall from a request to bid a major suit to a contract of 2♦. There are many other applications: for example, to pass partner's takeout double is to convert it to a penalty double.

Correct

In the bidding, to choose (usually) partner's first bid suit; in that case, a correction is equivalent to a preference.

COS

Acronym for Choice of Slams. An artificial or natural bid made to ask partner to select a strain from several choices where the slam might be played.

Count

1) (Noun) The number of cards held in a suit or suits, usually said of an opponent's hand.

2) (Verb) To determine, by inference or by follow-suit, the number of cards held in a suit by an opponent.

3) (Noun) In squeeze play, the number of tricks that declarer must lose before the squeeze can function.

Count signal

A defensive card play that shows whether the player has an even or odd number of cards in a suit.

Coup

1) Any extremely skillful play.

2) Any of several specific play techniques, such as the Scissors coup, Trump coup or Devil's coup.

Coup en passant

The lead of a side suit through an opponent who holds a higher trump so as to score a lower trump in the third hand.

Coup without a name

See Scissors coup. "Coup without a name" is an earlier term for the coup, conferred by Ely Culbertson.

Cover card

A card (honor or extra trump) which is known to compensate one of partner's losers; for example, a king in trumps covers partner's trump loser.

Crack

(Slang) To make a penalty double.

CRASH

1. An acronym for Color, RAnk and SHape, a convention used to show a 2-suited hand, as an overcall of opponents' strong 1 ♣ or 2♣ opening. The two suits share the same color (red or black), rank (majors or minors) or shape (rounded or pointed). The type of pairing is shown by the number of steps above the opening bid that are taken up by the overcall.

2. The play of two winners by a pair on a single trick: for example, the ace and king of trumps. The term is usually employed to describe declarer's use of a deceptive play to cause a defender to follow suit with one high card (for example, the K from Kx) when the other defender holds the singleton ace.

Crocodile coup

On defense, second hand's play of a higher card than apparently necessary, so as to obtain the lead. The play is intended to prevent fourth hand from being forced into the lead to make a return favorable to declarer. The name suggests a crocodile opening its maw to swallow up partner's winning card.

Cross

To enter the opposite hand. Normally used of dummy or declarer's hand: "He crossed to dummy in diamonds."

Crossruff

A playing technique in trump contracts, where extra tricks are gained by ruffing in both hands alternately.

Cross-IMP scoring

A form of IMP scoring in pairs tournaments, where each pair's score is determined as an (averaged) sum of differences to all other scores (rather than to a single datum score). Also known as X-Imps or Calcutta.

Cuebid (also, cue bid or cue-bid)

1) A bid of the opponents' suit in a competitive auction. Usually a conventional, forcing bid that shows strength or an unusual hand, or a particular distribution.

2) A bid that shows a control in a suit (usually with an ace or king, sometimes with a void), but does not indicate length or strength in the suit otherwise. See control bid. Partnership agreements indicate when in an uncontested auction a bid is considered a cue bid. Usually used in exploring for a slam contract.

Culbertson system

The earliest dominant bidding system, developed by Ely and Josephine Culbertson. Its principal features were an approach-forcing bidding style, four-card majors, strong two-bids and the use of an honor trick table to evaluate hand strength.

The curse of Scotland

The ♦9. The origin of the term is not known with certainty.

Cutthroat bridge

A form of three-handed bridge.

D

Danger hand

(Usually in reference to the defenders.) An opponent who, if he obtains the lead, can damage declarer's prospects.

Datum

The mean or median of raw scores on a deal. The datum is used as a basis for calculating IMPs for the participating teams or pairs. The datum may be trimmed by removing extreme scores at either end of the distribution, a procedure whose effect on a mean or on a median depends on the degree of skewness in the raw scores.

Dead

(Usually in reference to the dummy.) A hand that has no card of entry.

Deal

1) One particular allocation of 52 cards to the four players including the bidding, the play of the cards and the scoring based on those cards. Also called board or hand.

2) (Verb) To allocate the 52 cards to the four players or hands, 13 each.

Dealer

The player who makes the first call in the auction. In some versions of the game, this player also deals the cards. In rubber bridge, the first dealer is usually decided by a cut for the highest card. In duplicate bridge, cards are dealt only at the outset of the session and the deal is preserved during the session by the use of boards. The "dealer" who will make the first call is identified by a mark on the physical board, commonly the word "dealer".

Deck

The 52 cards used in bridge.

Declaration

The contract in which a hand is played.

Declarative-Interrogative

See D-I.

Declarer

Of the partnership that makes the final bid in the auction, declarer is the partner who first names the denomination or strain of the final bid, thus the strain of the contract. During the play, declarer sits across from the dummy and calls for cards from the dummy's hand, or "plays the dummy."

Declaring side

The side that wins the auction.

Deep finesse

A finesse against two or more cards.

Defeat

(Said of the contract). To prevent declarer from taking the number of tricks called for by his contract. Also, set.

Defenders

Defensive bidding

1) A bid or sequence of bids designed to hinder the opponents' bidding, including sacrifices.

2) All bidding by the partnership which does not open, which necessarily begins with a double or overcall (intervention).

Delayed

Postponed, as the jump preference in the auction 1♥ - 1♠; 2♦ - 3♥. Many bids have a different meaning depending on whether or not they are made at the first opportunity.

Denomination (also 'strain')

Component of a bid that denotes the proposed trump suit or notrump. Thus, there are five denominations - notrump, spades, hearts, diamonds and clubs. The Laws of Contract Bridge and of Duplicate Bridge refer to the term denomination exclusively but the Official Encyclopedia of Bridge states that "the modern term is strain"; strain is generally used in bridge literature.

DEPO

Acronym for Double Even, Pass Odd. Conventional method for bidding over interference with Blackwood.

Deschapelles coup

On defense, the lead of an unsupported honor so as to create an entry for partner.

Develop

To establish tricks in a suit, usually by forcing out the opponents' stoppers.

Devil's coup

In the endgame, the play of a side suit through a defender to create an overruff and a subsequent trump finesse.

D-I

(Abbreviation of Declarative-Interrogative.) 4NT as a general slam try that asks partner to show features. D-I is incorporated in several bidding systems, including Neapolitan, Blue Team Club and Kaplan-Sheinwold. 4NT D-I is distinguished from Blackwood by means of the bidding context.

Direction

A player's position at the bridge table (North, East, South or West).

Direct position

Usually said of a bid that is made immediately following RHO's bid. Contrast with balance.

Director

Referee (in duplicate bridge). The director enforces the rules, assigns penalties for violations, and oversees the progress of the game. The director may also be responsible for the final scoring. At a tournament there may be several directors, reporting to a Head Director. In ACBL-sponsored events, a director's ruling as to bridge fact may be appealed; a ruling as to discipline, so as to maintain an orderly event, may not.

Discard

1) (Verb) To play a card that is neither of the suit led, nor trump, and that therefore cannot win the trick.

2) (Noun) The card so played.

Discouraging card

A carding signal that discourages partner from leading a particular suit. Contrast with come-on.

Discovery play

A play, either by declarer or by the defense, intended to obtain information about the location of other cards.

Distribution

1) (Suit distribution) Of one suit on a deal, the numbers of cards or lengths in the four hands. Sometimes the length of a suit in one or two hands is known or presumed and its "distribution" covers only three or two hands, as "opposing distribution" said of the other pair from the perspective of one pair or player.

2) (Hand distribution, also shape or pattern) Of one 13-card hand on a deal, the numbers of cards or lengths in the four suits. Sometimes the length of one or two suits is known or presumed and "distribution" covers only three or two suits, as "distribution in the minors" said of one hand whose major-suit distribution is known.

General. The degree to which four suits in one hand, one suit in four hands, or all of the hands and suits are dealt in long and short holdings. Long and short holdings constitute "lots of distribution" and three-card holdings in particular constitute "no distribution".

Specific. Either way, four whole numbers that sum to 13 are commonly used to denote a distribution briefly, such as 4333 or 4-3-3-3 for a hand comprising one four-card suit and three three-card suits; or for a suit with one four-card holding and three three-card holdings in the four hands. Also 22 or 2-2 for the opposing distribution of spades when one pair holds nine of them; or for one hand's distribution in the minors when it holds nine in the Majors.

Fully specified. Conventionally neither 4333 nor 4-3-3-3 indicates which is the four-card suit in a hand while 4=3=3=3 means four spades, represented first, and three each in hearts, diamonds, and clubs. Thus 4=6=2=1 means 4 spades, 6 hearts, 2 diamonds, and 1 club.

Distribution point

A measure of one hand's strength due to the length or shortness of suits.

DONT

Acronym for Disturb Opponents Notrump. A conventional defense to notrump opening bids.

DOPE

Acronym for Double Odd, Pass Even. A conventional method for bidding over interference with Blackwood.

DOPI

A proxi-acronym for Double, O (the letter O standing for zero or none), Pass and I (the letter I standing for the numeral 1 or one). A conventional method for bidding over interference with Blackwood. Pronounced "dopey."

Double

1) a call that increases penalties if the opponents fail to make their contract, but consequently also increases the bonuses if they make it. A player can double only a contract bid by the opposition. Referred to as penalty double

2) a call having various alternative conventional meanings depending upon the bidding scenario. See informatory double, takeout double, negative double, lead-directing double, responsive double and support double.

Double dummy

(Adjective or adverb.) Said of a play or line of play that seems to be made with knowledge of all four hands, as if there were at least two dummies visible. Compare with single dummy.

When said of the defenders jointly, "double dummy defense" suggests that that pair knows all four hands and agrees on both goals and tactics such as falsecards, as if the cards were visible and they discussed those points.

Double dummy problem

A bridge problem presented for entertainment, in which the solver is presented with all four hands and is asked to determine the course of play that will achieve or defeat a particular contract.

Double finesse

A finesse for two missing cards.

Double into game

Down the line

To bid the higher of two adjacent suits before the lower. For example, of two five-card majors, the spade suit is normally bid before the heart suit. Contrast with Up the line.

Draw

To extract, usually trumps. To remove the opponents' trump cards is to "draw trumps."

Drive out

To force a stopper from an opponent's hand, usually by repeatedly leading the suit.

Drop

1) (Verb) To fall under a higher card: "The ♠Q dropped under the ♠K."

2) (Noun) That occurrence itself: "He played for the drop instead of finessing."

Duck

A play technique in which a player does not immediately play a card that might take a trick, but plays a small card instead.

Dummy

1) The partner of the declarer. Dummy's cards are placed face up on the table and played by the declarer. Dummy has few rights and may not participate in choices concerning the play of the hand.

2) The dummy's hand as exposed on the table.

Dummy play

The play of the hand by declarer. The apparent contradiction is due to the fact that declarer plays both declarer's cards and the dummy's.

Dummy reversal

A playing technique in trump contracts that gains extra tricks by ruffing in the hand that began with the longer trumps.

Dump

To lose a match deliberately, usually so as to assist another team or pair in the event. A subject of considerable controversy in the 1990s and beyond.

Duplicate bridge

A form of bridge where every deal is played at several tables, by several pairs, and their scores on each deal are subsequently compared. A minimum of two tables (four pairs) are required for a duplicate bridge event. Each entry might be a pair, or a team consisting of two or more pairs; the type of scoring varies accordingly. The hands of each deal are kept in metal or plastic containers called boards that are passed between tables.

Duplication of values

The possession of values in a single suit, in both partners' hands. Usually said of high card values in one hand paired with a singleton or void in partner's hand. Such a holding is normally undesirable: ♠KJ9 facing a void is much less useful than ♠KJ9 facing ♠Q4.

E

Eastern Scientific

A bidding style that developed in the Eastern United States, particularly the New York region. It is characterized by five-card majors with a forcing one notrump response and limit raises, strong notrump with Jacoby transfers, and strong (but not game forcing) two-over-one responses.

EBL

European Bridge League, the official organising body of bridge in Europe.

EBU

English Bridge Union, the official organising body of bridge in England.

Echo

The play of first the higher, then the lower of two cards of the same suit on separate tricks to encourage or, by prior agreement, to discourage (see upside-down signals) partner's continuation of a suit; or to signal possession of (normally) an even number of cards in the suit at the time the higher card is played.

EHAA

Acronym for Every Hand An Adventure, a bidding style that emphasizes very weak notrump opening bids (often 10-12 HCP), four-card majors, and undisciplined weak-two bids.

Eight ever, nine never

A Bridge maxim that advises players when to finesse for a missing queen. With eight cards in the suit, always ("ever") finesse; but with nine cards, never finesse, rather play for the queen to drop under the play of the ace and king. Experienced players often ignore this advice in favor of considerations such as the danger hand, combination play, and the known or inferred distribution of other suits.

EKB

Acronym for Exclusion Keycard Blackwood, a variant of the Roman Keycard Blackwood, which shows a void in the bid suit and asks partner to exclude the named suit ace if held.

Elimination

The removal, by playing a suit or suits, of safe exit cards from defenders' hands, normally in preparation for an endplay. The classic (but not the only) example is to leave an endplayed defender with the choice of conceding a ruff and discard or giving declarer a free finesse.

Elope

To win a trick by ruffing with a trump lower in rank than an opponent's trump. The Coup en passant is an example of an elopement.

Encrypted

An agreement that the meaning of bids or card signals may change as more information about a deal becomes available. For example, when declarer shows out of a suit, the defenders can tell whether the rank of West's lowest remaining card in the suit is even or odd (and declarer probably does not have that information). The defenders might have agreed that if West's lowest remaining card is even, normal attitude signals will be in effect, but if it is odd, upside-down signals will be used. In such a case, the defenders' agreement is encrypted.

Ending

The layout of the cards when just a few tricks remain to be played. In a "four-card ending", each player has four cards left. Such positions can be of special interest because squeezes and other endplays tend to occur near the end of the play.

Endplay

A play which forces a particular opponent to win a trick, so that that opponent must then make a favorable lead. That player is said to be "endplayed". Normally, the player who is endplayed is a defender. Although the word implies that the play occurs toward the end of a hand, it often occurs earlier, and in exceptional cases the opening leader can be said to be "endplayed at Trick One."

Enter

1) To win a trick in the opposite hand, thereby giving it the right to lead to the next trick.

2) To make the first call for a partnership after the opponents have bid.

3) To join a bridge competition.

Entry

1) A card that allows a particular hand to win a trick that partner or an opponent has led to. Entries are vital to communication.

2) A seating assignment in a bridge competition. Entries designate the participants' initial table number, direction at that table, and (if applicable) section.

Entry-shifting squeeze

A squeeze in which the declarer decides whether to overtake the squeeze card or to let it hold the trick, depending on the play of the intervening opponent.

Entry squeeze

A squeeze that puts pressure on a holding that interferes with declarer's entries.

Equal level conversion

An agreement concerning rebids after take-out doubles. Traditionally, the bid of a new suit by the player who has made a take-out double is considered forcing. Under the equal level conversion agreement, the bid of a new suit by the doubler is not forcing if it is at the same level as advancer's bid. So, equal level conversion means that in the sequence 1♠ - (Dbl) - P - (2♦); P - (2♥), 2♥ is considered non-forcing.

Equals

Cards in one hand that are adjacent in rank and thus have equal trick-taking power.

Escape suit

A long suit to which a bidder can escape if necessary or desirable. The bidder of a comic notrump might run to his long suit if doubled.

Establish

To make winners of the remaining cards in a suit by playing or forcing out higher cards.

Even

1) A split with the same number of cards in each hand. A 2-2 split is an even split.

2) Of the number of cards in a suit found in a hand: two cards, four cards, and so on.

Event

A duplicate bridge contest.

Exclusion bid

A bid, such as 2♦ in the Roman Club system, that shows length in all suits except the one named.

Exclusion Blackwood

Factoring

The adjustment of matchpoint scores to correct for dissimilar conditions. For example, a game played with a Mitchell movement might have an extra N-S pair, causing a bye round for N-S. The top is therefore lower for N-S pairs than for E-W pairs, and the N-S scores are multiplied by a fraction (or "factor") to make them commensurate with the E-W scores.

Fall

To be captured by a higher card. See drop.

False preference

A return to partner's first-bid suit despite a longer holding in the second suit. Usually intended to give partner an opportunity for another bid.

2) Flat board: A deal in duplicate bridge that results in scores across the field that are identical, or nearly so.

Float

1) To be followed by two or three passes. For example, West's spade bid "floated around" to South in 1♠ - (P) - P.

2) To fail to cover the card led, usually by two consecutive hands. "South floated the ♠Q to East."

Flower movement

An adaptation of the Howell movement in which the players, rather than the boards, progress regularly from table to table. Also known as "Endless Howell."

Follow suit

To play a card of the same suit as the one that was first led to the trick. Failure to follow suit when one can do so constitutes a revoke.

Force to

To bid with the intention of causing the bidding to proceed to a particular level. For example: "In this auction, 2♣ forced to game", or "My reverse forced to the three-level."

Forcing bid

A bid that, by partnership understanding, requires the bidder's partner to make another bid. A forcing bid is not necessarily a strong bid. It is legal to pass partner's forcing bid, and players occasionally do so if they believe it advantageous on a given hand, but it is damaging to partnership confidence.

Forcing defense

The lead and subsequent continuation of a suit that the defenders believe declarer will have to ruff in the long trump hand. The strategy is to shorten declarer's trump holding so as to leave the defenders in control of the hand. See Tap.

Forcing notrump

An agreement that a 1NT response to a 1♥ or 1♠ opening is a forcing bid.

Forcing pass

1) A pass in a competitive auction that requires partner either to make another bid or to double or redouble the opponents' current call.

Fouled board

A board whose cards are not distributed as they were when first played, due to returning the cards to their slots erroneously.

The four-card major agreement was standard during the first four decades of contract bridge, but has since given way to five-card majors in "standard" systems such as 2/1 game forcing and Standard American.

Four-deal bridge

See Chicago.

Fourth

1) A player needed to complete a table, usually said of rubber bridge.

2) Of four-card suit length: for example, Q987 is referred to as "queen-fourth."

Fourth hand

The fourth player with an opportunity to bid, or to play to a trick.

Fourth suit forcing

1) The initial use of a bid of the fourth suit as forcing to some level.

2) An agreement that the partnership's bid of the fourth suit, in addition to its forcing nature, is possibly artificial.

Fragment

A holding of three or even two cards in a suit, thus not long enough to suggest as a trump suit. A partnership may treat the bid of a fragment as a means of implying shortness in another suit (see fragment bid). A fragment may also be bid after the single raise of a major as a help suit game try.

Fragment bid

A second-round jump bid (usually a double jump) that by agreement shows a fit with partner's last-bid suit and shortness in another suit. Under this agreement, in 1♣ - 1♥; 3♠ the bid of 3♠ is a fragment bid, showing a fit for hearts and a singleton or void in diamonds. The suit of the fragment bid is often three cards long. Compare with splinter bid.

Freak

(Also, "freak hand.") A hand with a very long suit or suits. Most would regard a hand with two six card suits as a freak.

Free bid

A bid that is made when a pass would still allow partner to make a bid. Normally used of a bid that is made after partner has opened the bidding and RHO has overcalled.

Free finesse

A position in which a player leads up to an opponent's tenace, solving that opponent's possible guess. The term is normally used when the player is forced to make that lead.

Frozen

Template:BridgeSuitRight

A frozen suit is one that neither side can play without damage to its own holding in the suit. Declarer can sometimes duck the defense's lead to freeze the suit. The following suit is frozen:

G

Gambling 3NT

An opening bid of 3NT. The bidder hopes to make the contract by means of a long minor suit rather than by a preponderance of high cards.

Game

A contract, bid and made, worth 100 points or more. The undoubled game contracts are 3NT (40 for the first trick + 30 each for the second and third); 4♥ and 4♠ in the majors (4 tricks × 30 points per trick); 5♣ and 5♦ in the minors (5 tricks × 20 points per trick). Game can also be made via a doubled or redoubled contract: e.g., 2♠ doubled is worth 2 × (2 tricks × 30 points per trick) = 120 points. The pair bidding and making the game is awarded a bonus.

Game force

A bid that asks partner not to pass before the partnership's bidding has reached game (or the opponents have been doubled at a level high enough to compensate). Some treatments relax the requirement: for example, the agreement that in the sequence 1M - 2m, the 2m response is a game force unless the suit is rebid. So, in 1♠ - 2♦; 2♥ - 3♦, 3♦ would cancel the game-forcing message of the 2♦ bid.

Game try

A bid, often in a side suit, which invites the partner to bid a game if he has extra values in the context of the prior bidding. A help-suit game try is made in the suit where one hopes that partner holds cover cards. A short-suit game try is made in the suit where one hopes that the partnership has no duplication of values.

Good

Said of a card or cards that have been established.

Goren system

A system of bidding, dominant in the United States from the 1940s through the 1960s, based on the Culbertson system. The principal difference between the two systems was in hand evaluation: Culbertson used honor tricks to assess a hand's strength whereas Goren used High card points.

Gouging

Template:BridgeSuitRight

Involves leading or following suit with a high card which, although unable to win the trick or promote anything, nevertheless pins declarer in the wrong hand. This type of play can be made for a variety of reasons.

In the example at right, when declarer leads low to the king, you can win and, if necessary return the jack to pin declarer in the dummy. This gouging play will succeed when partner has a trump and declarer can´t get off the dummy or when you have a finesseable trump position and declarer can't get to hand in time for the finesse.

Goulash

A style of dealing, usually in rubber and Chicago games, where the cards are not thoroughly shuffled between deals and are dealt in groups. It results in "wild" card distributions.

Grand coup

A trump coup in which the cards ruffed in the long trump hand are already winners.

Grand slam

A contract to win all thirteen tricks. Bidding and making a grand slam scores significant bonus points.

Grand slam force (GSF)

A method of determining whether the partnership holds the top trump honors when the bid of a grand slam is a possibility. In its original form, the GSF was initiated with a bid of 5NT, asking partner to bid a grand slam with two of the top three honors in the trump suit. Depending on the prior bidding, other bids are often used in place of 5NT, and there is a variety of schemes for responding to the GSF. See Josephine.

Grosvenor gambit

A play that creates no direct advantage and might lose. Its principal features are that an opponent will not suspect that such an inept play has been made, and that once the opponent realizes what has occurred, he will be frustrated and angry (and therefore less effective) during subsequent hands. The ploy was first described in a satiric story by Frederick B. Turner in the June 1973 issue of The Bridge World.

Guard

A holding that prevents an opponent from taking a trick or tricks. See stopper.

H

Hand

Hand record

A document that lists the cards in each hand of every board played in a duplicate bridge session. Often, hand records also list contracts each partnership can make with double dummy declarer play and double dummy defense.

Help-suit game try

The bid of a side suit after a single raise, used to help partner evaluate game prospects when opener's hand is roughly a trick stronger than a minimum opening. For example, after 1♥ - 2♥, opener might rebid 3♣ with a side club suit or a strong club fragment. The bid tells partner where high cards will be most helpful, and requests partner to take positive action, such a direct jump to game, with strength in that suit. Otherwise, the bid requests partner to sign off (in this example, by bidding 3♥). See short-suit game try and game try.

Hesitation

A brief pause before a bid or play, considered somewhat shorter than a Huddle.

1) (Verb) To defer taking a winning card until an advantageous point in the hand, usually in reference to tricks that the opponents have led to. There are various purposes for holding up a winner, but it is frequently done to force the opponents to use their entries too soon.

2) (Noun) The act of holding up a winner.

2) (Verb) To perform the IMP score conversion.

Impropriety

A breach of ethical conduct or etiquette; an action that violates the Proprieties.

IMPs

The form of duplicate bridge that uses IMPs as a scoring method, as distinct from a game scored at matchpoints.

In back of

Template:BridgeSuitRight

A card or holding that is to the left of, or behind, or over another. To say that the ♠A is in back of the ♠K is to say that the ace is to the left of the king, or behind it, or over it; so, the ♠A is in a position to directly capture the ♠K.

Individual

A form of duplicate bridge, scored at matchpoints, in which each player is paired with a different partner on each round.

Informatory double

A double that is intended to convey information rather than to exact a penalty from the opponents.

In front of

Template:BridgeSuitRight

A card or holding that is to the right of or under another. To say that the ♠A is in front of the ♠K is to say that the ace is to the right of the king, or under it, and normally cannot capture the ♠K if it is guarded.

Insufficient bid

A bid that is not higher than the immediately preceding bid, and therefore illegal.

Insult

(Slang) The bonus for making a doubled or redoubled contract is sometimes referred to as the "insult" or as being "for the insult".

Insurance bid

Interference

A call, such as an overcall or an initial preempt, that is intended to make it more difficult for the opponents to bid to their best contract.

Intermediate

1) Nines, eights and sevens are sometimes termed "intermediate cards." See body.

2) A jump overcall that by agreement may be made with a hand of opening bid strength and a long suit is termed an "intermediate jump overcall."

3) An opening two-bid that by agreement may be made with values just short of those required for a game-forcing opening bid is termed an "intermediate two-bid."

Intra-finesse

A technique that involves successive finesses against both opponents.

Inverted minors

J

Jacoby transfers, or simply "transfers"

A convention initiated by responder following partner's notrump opening bid that requests opener rebid in the suit ranked just above that bid by responder, i.e. a response in diamonds requests a rebid in hearts and a response in hearts requests a rebid in spades; other responses may carry other meanings; designed to make the stronger hand declarer.

Jacoby 2NT

By agreement, a forcing raise of a major suit opening bid, used in conjunction with limit jump raises. Opener is requested to rebid in a suit where he holds a singleton so that responder can better evaluate the fit.

Jam the bidding

(Slang) To preempt.

Jettison

The discard of an honor, often by a defender, and usually to unblock a suit.

Josephine

Journalist leads

Opening lead convention, mainly against notrump contracts, designed to show both what the leader has, and to request specific partner actions in return.

Jump bid

A bid made at a level higher than the lowest level at which that suit could be legally bid.

Jump overcall

An overcall made at higher than the minimally legal level: for example, 1♥ - (2♠). In the 1930s, jump overcalls were treated as strong bids. They are now more frequently treated as weak, preemptive bids.

Jump preference

A preference to partner's first-bid suit, made at a level higher than the minimally legal level. In the following sequence, 3♥ is a jump preference: 1♥ - 1♠; 2♦ - 3♥. For many years, the jump preference was treated as invitational except in support of opener's minor, when it was treated as forcing. As of 2001, however, most experts treat all three-level jump preferences as invitational following opener's one-level new suit rebid: e.g., 1♣ - 1♦; 1♠ - 3♣

Jump raise

A raise of partner's suit one level higher than the minimum legal raise. For example, 1♥ - 3♥ or 1♦ - 1♥; 3♥

Jump rebid

A rebid of one's original suit, one level higher than necessary, usually showing a six-card suit: for example, 1♦ - 1♥; 3♦. The range of strength shown by a jump rebid is a matter of partnership agreement: some treat it as a one-round force, others (particularly if playing Kaplan-Sheinwold and the rebid suit is a minor) play it as only a little weaker than a game-forcing opening bid.

Jump shift

A jump bid of a new suit.

1) As a rebid by opener (e.g. 1♥ – 1♠; 3♣) or responder (e.g. 1♥ – 1♠; 1NT – 3♣), it indicates extra strength

2) As direct response (e.g. 1♥ – 2♠): usually, a very strong hand. However, another treatment (weak jump-shifts, requiring prior partnership agreement) uses the bid to show a weak hand and a long suit.

K

Kaplan-Sheinwold (K-S)

A bidding system that uses five card majors and the weak notrump.

Key-card Blackwood

An "ace-asking" convention that counts five keycards, four aces plus the king of the apparent trump suit. Commonly there is a follow-up to ask about the queen of trumps, effectively sixth keycard.

Kibitzer

A spectator.

Kickback

Kiss of death

At pairs, plus or minus 200. A score of minus 200, down two undoubled and vulnerable, or down one doubled and vulnerable, is a likely bottom against a part score by the opponents. A score of plus 200 from making five-odd of a major after stopping in a partial, is a likely bottom against the game contracts bid by other pairs holding the same cards.

Knockout

A type of team-of-four tournament in which the winning teams from each round advance to the next. The losing team is removed from play (but see repechage). In a double knockout a team is removed from play only after losing two matches.

Knockout squeeze

A type of squeeze that operates in part against the defender's trump holding, when the defender threatens to win a plain suit trick and then lead a trump, thus reducing declarer's ruffing tricks. It is usual to term this play a knockout squeeze when the squeezed defender is second to play to the trick, and to term it a backwash squeeze when the squeezed defender is fourth to play.

Kock-Werner Redouble

A rescue mechanism employed when partner's bid is doubled for penalties. Invented by Rudolf Kock and Einar Werner from Sweden. See also SOS Redouble.

L

Last Train

A conventional bid that is one step above the current bid and one step below game in a trump suit. It is a mild slam try and conveys no information about the suit bid. After 1♥ - 3♥; 4♣, 4♦ is Last Train, invites slam, and does not necessarily show a diamond control.

Late play

A board that is played after the remainder of the event has finished, usually because of slow play or an irregularity.

Law of Total Tricks (LTT, "The Law")

A guideline stating that the total number of cards held by both sides in their longest trump fits equals the total number of tricks available to both sides in their best trump contracts. See Hand evaluation.

The Law is sometimes interpreted to mean that one side can profitably contract for a number of tricks equal to its own combined trump length; for example, compete to 3♠ with a nine-card spade fit.

Laws of Contract Bridge and Laws of Duplicate Bridge

The definitions, procedures and remedies that define how rubber bridge and duplicate bridge are played. The Laws include the Proprieties, which discuss the game's customs and etiquette — often far more important than procedural matters. The Laws apply worldwide. Individual sponsoring organizations, such as the ACBL and the EBL, establish their own regulations for play, which may amplify the Laws but may not conflict with them.

One important difference between the laws of rubber bridge (contract) and duplicate bridge is that rubber players are expected to deal with irregularities themselves while duplicate players are expected to call the director.

Laydown

A contract that can be made on any rational line of play.

Lead

1) The first card played to a trick, which dictates the suit that others must play if able to do so (see follow suit).

2) The hand that is entitled to lead to the next trick is said to be "on lead" or to "have the lead."

3) See opening lead.

Lead-directing double

A double by the partner of the prospective opening leader that requests the lead of a particular suit. Experienced partnerships usually agree on a set of suit priorities, such as opening leader's bid suit, doubler's bid suit, dummy's first bid suit, or a suit that dummy has just bid conventionally.

Lead out of turn

Playing a card when it was another player's turn to lead. Subject to penalty.

Lead through strength

A maxim that advises a defender to lead a suit in which LHO has high card strength, forcing declarer to play high or low before third hand plays. The corollary is that a defender is advised to lead up to weakness in the fourth hand.

Leap

To make a jump bid.

Leave in

To pass, often used of passing when partner's double was followed by a pass.

Lebensohl (Leb)

Responder's bid of 2NT as a puppet to 3♣ in preparation for a sign-off. Normally used after an overcall of partner's 1NT opening, or after a double of partner's weak two bid. Also used after opponents weak two bid and partner's balancing take-out double.

Leg

(Slang) game. Normally used in reference to rubber bridge. "A leg up" means being vulnerable vs. non-vulnerable opponents. "Cut off their leg" means becoming vulnerable vs. opponents who are already vulnerable.

Length

The number of cards held in a suit.

Level

1) The number of tricks that (when added to the book of six tricks) a bid or contract states will be taken. For example, a bid at the four level contracts to take (6 + 4) = 10 tricks.

2) The property of a contract that states whether it is at the part-score, game or slam level.

Lever

Slang expression for double

LHO

Left-hand opponent

Light

(Adv.) To enter the auction with relatively low values (for example, to "open light" or "overcall light"). To do so can be either a matter of tactics or of general style.

Lightner double

A penalty double, usually of a slam contract, that requests partner to choose an unusual suit for the opening lead. This criterion tends to regard as typical (and thus to exclude) a trump lead, the lead of defenders' bid suit, and the lead of an unbid suit.

Limit

In the bidding, to define a hand's strength with some degree of precision.

Limit jump raise

An invitational jump raise of a major suit, such as 1♥ - 3♥. Limit jump raises usually guarantee at least an 8-card fit in partner's major suit and around 10-11 HCP or the distributional equivalent.

Limit raise

Any call which invites partner to bid game in a suit partner has bid, previously. A limit raise promises trump support and hand strength about a king less than a minimum strength game force.

Line

1) (with "the"): A line on a bridge scorepad that separates points for tricks that count toward game (see Below the line) from those that do not (see Above the line).

2) On a given hand, the play strategy that is adopted by declarer or by the defenders.

2) Any suit of unusual length.

Loser

A card which apparently cannot take a trick.

Loser on loser

A card play tactic that attempts to create an advantage by playing two losers, often of different suits, on the same trick. Loser-on-loser play has many applications, including the creation of a ruffing position for declarer, the avoidance of overruffs by the defense, and interference with the opponents' communications.

Major penalty card

A card that is exposed by a defender prematurely and through intentional play; or, an honor card that is exposed prematurely even if accidentally. A major penalty card remains face up on the table to be played at the first legal opportunity, including as a discard. Compare with minor penalty card.

Major suit

The heart suit and the spade suit are major suits. Declarer scores 30 points for each trick taken in an undoubled contract with a major suit as trump. Because game requires at least 100 points for tricks bid and made, both 4♥ and 4♠ (or 2♥ doubled and 2♠ doubled) constitute game contracts. Compare with minor suits.

Major tenace

The highest and the third highest remaining cards in a suit, held in the same hand. For example, the ♠AQ before spades have been played. Tenaces define the structure of finesses. See minor tenace.

Matrix

The layout of the cards that play pivotal roles in certain endplays, most typically squeezes.

Maxims of bridge

A brief expression of a general principle - most have some validity but none are true in all circumstances.

Maximal overcall double

By prior agreement, a game-invitational double of an overcall that leaves no room for a bid, when a bid would invite game. For example, after 1♠ - (2♥) - 2♠ - (3♥) there is no room below 3♠ for a game invitation (and a bid of 3♠ itself would be taken as merely competitive), so a double is used as a game invitation.

McKenney

See Suit preference signal.

Menace

A card that requires an opponent to retain a higher card in the same suit, as a guard. The term is typically used of squeeze play.

Merrimac coup

The lead of an unsupported high card to force an opponent to use an entry before it can be used effectively. Named for a ship sunk during the Spanish-American War, to block the entrance to a harbor. Sometimes confused with, and spelled as, the Merrimack, the American Civil War ship that fought the Monitor. See Deschapelles coup.

Michaels cue bid

By prior agreement, an immediate cue bid of an opening bid, such as 1♦ - (2♦), for two-suited takeout. The cue bid of a minor suit shows length in both major suits. The cue bid of a major suit shows length in the other major suit and in an unspecified minor suit.

MiniBridge

Minor penalty card

A card below the rank of an honor card that is exposed by a defender prematurely but accidentally, via mishap. A minor penalty card remains face up on the table until played. The minor penalty card must be played before any other card below honor rank in the same suit; however, an honor in the same suit may be played before the minor penalty card is played. Compare with major penalty card.

Minor suit

The club suit and the diamond suit are minor suits. Declarer scores 20 points for each trick taken in an undoubled contract with a minor suit as trump. Because game requires at least 100 points for tricks bid and made, both 5♣ and 5♦ (or 3♣ doubled and 3♦ doubled) constitute game contracts. Compare with major suits.

Minor tenace

The second-highest and the fourth-highest (or lower) remaining cards in a suit, held in the same hand. For example, the ♠KJ before spades have been played. See major tenace.

Mirror

Mitchell movement

A pairs tournament movement in which the pairs sitting in one direction (usually North-South) stay in the same seats throughout, but after each round the pairs sitting in the other direction (usually East-West) move to the next higher numbered table, and the boards are moved to the next lower numbered table. Unless an arrow switch is performed, the effect is to create two events, a "North-South" contest and an "East-West" contest, with separate winners.

Mixed

1) Of an event: contested by pairs or teams in which every pair comprises one male and one female player.

2) In the auction: A mixed raise is, by agreement, a jump cue bid of opener's suit in support of partner's overcall. It tends to show four card support for partner's suit and the strength of a good single raise. In 1♦ - (1♥) - 1♠ - (3♦), 3♦ is a mixed raise.

Morton's fork coup

A play that forces the defense to choose between taking a high card that will establish extra winners for declarer, and ducking the trick, after which the high card cannot be cashed.

Movement

In a tournament, the scheme for the progression of players and boards from table to table, arranged so that a pair does not play the same boards twice, or meet the same opponents twice etc. The most common movements for pairs tournaments are Howell and Mitchell.

Moysian fit

A 4-3 trump fit. Named after Alphonse "Sonny" Moyse Jr., long-time editor of The Bridge World, who wrote and published a variety of articles that promoted the virtues of such fits, and bidding styles designed to locate them.

MUD

Negative double

A conventional call used by responder in a competitive auction to denote possession of at least one unbid suit.

Negative free bid

Responder's suit bid following an opening bid and an overcall. Nonforcing by prior agreement.

Negative inference

Negative response

A bid that shows insufficient values for a stronger response. For example, a 2♦ response to a forcing 2♣ opening bid is often negative, as is a 1♦ response to a Precision 1♣.

Negative slam double

In a competitive auction, the double of a voluntarily bid slam to show no defensive tricks, and therefore to suggest a sacrifice.

Neuberg formula

In duplicate pairs tournaments, a method of fairly adjusting match point scores when not all boards have been played the same number of times. It gives equal weight to each board by calculating the expected number of match points that would have been earned if the board had been played the full number of times.

Non-forcing bid

A bid which partner may pass. See also forcing bid, invitation, sign-off.

Non-vulnerable

The state of vulnerability in which both bonuses and penalties are smaller. Therefore, less is at stake for a non-vulnerable pair investigating game or slam, or that is contesting the part score, than for a vulnerable pair. Also, "not vulnerable."

Nonadverse suit

A suit which has not yet been bid by either opponent.

None vulnerable

In rubber bridge, the state of the score in which neither pair has made a game. In duplicate bridge, the vulnerability condition under which neither pair is designated as vulnerable for the board in play. Also, "neither side vulnerable."

O

Obligatory

1) Of a finesse: A duck, made in the hope that a high card will fall. For example, declarer holds ♥K432 opposite dummy's ♥Q765. The ♥2 is led to the ♥Q, which wins. Declarer now leads dummy's ♥5 and RHO follows with the ♥J. Declarer ducks, hoping that LHO must now play the ♥A. The play is obligatory because given the first heart trick, no other play can yield three tricks.

2) Of a falsecard: A falsecard that, like an obligatory finesse, cannot lose and might gain. An example is the play of the card that one is known to hold (for example, the play of a queen after it has been successfully finessed).

Odd

Specifying a level. To make 4♥ is to make four-odd.

Odd-even discards

A defensive carding scheme under which the play of an odd-numbered card is encouraging and that of an even-numbered card is discouraging. The rank of the card may be used to show suit preference.

Off the top

Said of some number of tricks that can be lost or won without gaining or losing the lead. "There were eleven tricks off the top in spades", to mean that declarer could take eleven tricks without interruption; or, "We're down off the top", to mean that the defenders can take at least four immediate tricks against 4♥.

Offside

a) not by invitation only (invitational event)

b) not by qualification in a preceding event or qualifier

c) not by representation of geographic zones, nations, cities, clubs, etc; nor by requirement that pair or team members share geographic residence, club membership, etc (national event, etc)

d) not by age, sex, or playing record (seniors, Masters, etc).

Open is generally ambiguous but it does have the last sense (d) in the names of WBF world championship events, where the relevant Categories are Youth (with subcategories), Seniors, Women, and Open. For the WBF, transnational means open in sense (c).

2) To play, from third hand, a lower card than the one led to the trick. If declarer leads the ♥J, LHO plays a small heart, and declarer plays the ♥2 from dummy's ♥AQ2, declarer has passed the ♥J.

Pass and pull

To make a forcing pass and on the next round remove partner's double by bidding.

Passed hand

A player who passed instead of opening the bidding. The inference is that a passed hand does not hold the values required to open the bidding (unless playing a strong pass bidding system).

Passed out

1) A deal is passed out if the auction begins with four consecutive passes. There is no contract, no play of the hand, no score. The players proceed to the next deal.

2) A bid, double, or redouble (an action) is passed out if it is followed by three passes, which end the auction. The last action identifies the contract and the play follows.

Passive defense

2) A remedy assigned by a director to redress damage done by an infraction. The penalty for a minor, procedural infraction might be some number of tricks, matchpoints or IMPs, or disallowing a particular bid or play. A more serious violation of the game's Proprieties may be imposed by barring the offender from an event, a portion of an event, or from organized bridge.

An alert which must be made at the beginning of the round before play begins on the first board. Different national governing organizations may establish different requirements for prealerts. Examples of methods for which the ACBL requires a prealert include the following:

• An agreement to lead the small card from "xx" on opening lead
• An agreement (canapé) to bid the shorter of two suits before the longer suit with a two-suited hand
• An agreement to use any bidding convention that entitles the opponents to consult a written defense during the auction

Precision

A bidding system that combines the features of Kaplan-Sheinwold with a strong, artificial 1♣ opening bid.

Preempt or Preemptive Bid (or Raise)

1) A bid (or raise) predicated on length of a suit rather than overall strength, primary function of which is to interfere with the opponents' bidding by taking away bidding space they need to exchange information.

2) (Noun) A bid that has a preemptive effect, regardless of its intent.

Preference

A call that returns the bidding to partner's first-bid suit; for example, in 1♥ - 1♠; 2♦ - 2♥, 2♥ is a preference. A simple, non-jump preference shows neither strength nor support for the suit; it is simply a return to partner's presumably longer suit.

Prepared bid

A bid, often a slight violation of a partnership agreement, that is chosen to avoid a later bidding problem. Playing five-card majors, for example, the decision to open a strong four-card spade suit in preference to a weak five-card heart suit.

Prepared club

See Short club.

Present count

A carding agreement under which a count signal shows the number of cards currently held. In a count-giving situation, a defender might first play the ♥3 from ♥753, and the ♥7 as his second play. Also, "current count."

Principle of restricted choice

A guideline to the play of the hand, concerning the probability of the location of key cards in the unseen hands.

Protect

See balance.

Protest

See appeal.

Pseudo squeeze

A position that, to a defender, appears to be a true squeezed position, but is not. Declarer hopes that the defender will misplay as a result. The literature often gives as an example a position in which declarer has a void in dummy's apparent suit of entry.

Psych, psyche, psychic, or psychic bid

A call that grossly misstates high card strength or distribution, made so as to deceive the opponents. The Laws specify that psychic bids themselves are legal. It is, however, a violation to infer and fail to disclose that partner has psyched, when the inference is based on partnership agreement or experience. Sponsoring organizations regulate the use of certain psychic bids.

Psychic control

A bid that, by partnership agreement, announces that the player's previous bid was a psychic.

Pull

1) To remove the opponents' trumps.

2) To remove partner's double.

Qualifying

(Adjective) A session or sessions preliminary to the final of an event.

Quantitative

1) Of a bid: A call based, usually, on high card points, rather than a feature such as fit or shortness. A raise from 1NT to 3NT based on a 4-3-3-3 hand with 10 HCP is a quantitative raise.

2) Of scoring: The method of scoring used in rubber bridge or in IMP events. The metric used is the number of points earned on each deal, perhaps adjusted by the IMP scale and victory points. In contrast, comparative scoring is based on the number of pairs that have been out-scored.

Queen-ask

In Key Card Blackwood, the cheapest bid over the response to 4NT, to ask responder for the trump queen.

Quick tricks

see honor tricks

Quitted trick

A trick whose cards have all been turned face down (duplicate bridge) and gathered in front of the trick's winner (rubber bridge). In rubber bridge, a player may inspect a quitted trick if his side has not yet led to the next trick. In duplicate bridge, a player may inspect a quitted trick only if told to do so by a director.

2) A bid by the same player in a suit he has already bid.

Rebiddable suit

A suit with sufficient length and strength, according to partnership agreements, to be rebid in certain defined circumstances.

Recorder

A member of a bridge organization whose responsibility it is to maintain a record of reports of possible violations of the Proprieties.

To lose some number of tricks in preparation for a squeeze. Losing the tricks "tightens up" the position, removing idle cards from the defenders' hands before they can be used as safe discards in the squeezed position.

Red

(Slang) Vulnerable. From the color of the paint on a duplicate board. Also: "Red vs. red" to mean both teams vulnerable, and "red vs. white" to mean vulnerable vs. not.

Redeal

In rubber bridge, the prescribed remedy for a faulty deal. In duplicate bridge, redeals are not used except in special cases and under a director's supervision.

Retain the lead

Maintain the right to lead to the next trick by leading and winning the current trick.

Return

To lead back, usually the suit that partner led.

Reverse

A bidding sequence in which a single player, on consecutive calls, bids two different suits, and bids the two suits in the reverse order to that expected by the basic bidding system. The specific definition of a reverse therefore depends on the bidding system. The reverse is designed to show additional strength without the need to make a jump bid. Because the reverse takes up bidding space, the reverse bidder is usually expected to hold a stronger than average hand, usually more than 16 HCP.

Revoke

Failure to follow suit as required when a player is able to do so.

Rewind

(Slang) To redouble.

RHO

Right-hand opponent.

5) Roman discards: odd-even discards.

6) Roman leads: Rusinow leads.

RONF

Acronym for Raise Only Non-Force. A treatment used for responding to preempts, usually weak two bids. All bids except the single raise are forcing.

2) In duplicate bridge, a set of boards leading to another round (e.g., the semi-final round), or a set of boards that two pairs play against one another.

3) Of a control, the round on which the control can stop the opponents from winning a trick. An ace, for example, is a first round control; the king is a second round control.

Rubens advances

Transfer advances of overcalls. See Useful Space Principle.

Ruff

To play a trump on a trick when a plain suit was led.

Ruff and discard

The lead of a suit in which both opponents are void, so that one opponent can ruff while the other discards (or sluffs). A ruff and discard is usually damaging to the side that leads to the trick. Also, ruff and sluff or ruff and slough.

Ruff out

To establish a suit by ruffing one or more of its low cards.

Rule of Eight

A way to decide whether to overcall an opponent's 1NT opening. Length in long suits, the losing trick count and HCP are combined.

Rule of Eighteen

Some federations have adopted strict rules to limit the destructive effect of very weak openings. One is this Rule of 18, which states: "The sum of the number of cards in the two longest suits plus the number of HCP must equal or exceed 18". For instance, with a 5-5 distribution, 8 HCP are needed.

Rule of Eleven

A calculation that can be used when it is assumed that opening leader has led the fourth highest card in a suit. By subtracting the pips on the card led from 11, the result is the number of cards in the other three hands that are higher than the one led. Third hand, for example, can then make inferences about declarer's holding in the suit by examining his own and dummy's holdings; likewise, declarer can make inferences about right-hand-opponent's holding in the suit.

Rule of Five

When the bidding has reached the 5-level in a competitive auction, tend to defend rather than bid on. In other words, in competitive auctions, 5-level contracts belong to the enemy. See also Law of Total Tricks

Rule of Four

Avoid giving support for partner's 5-card suit if a superior 4-4 fit might be available.

Rule of One

When there is just one trump out higher than yours, it is normally best to leave it out.

Rule of Seven

To help interventor to decide if s/he is strong enough to double opponent's preemtive opening: "Interventor adds at his real HCP count an average of 7 HCP, supposed to be partner's strength. If the total is at least 21 and interventor has at nost a doubleton in the preempt suit, s/he should double. If s/he has 3 cards s/he must deduct 1 point from the total. If advancer is obliged to bid at the 3 level, interventor should be slightly stronger."[1]

Rule of Ten

A calculation that can be used when it is assumed that opening leader has led the fifth highest card in a suit. By subtracting the pips on the card led from 10, the result is the number of cards in the other three hands that are higher than the one led. Third hand, for example, can then make inferences about declarer's holding in the suit by examining his own and dummy's holdings; likewise, declarer can make inferences about right-hand-opponent's holding in the suit.

Rule of Three

On a competitive part score deal, with the points roughly equal between your side and theirs, once the bidding has reached the 3-level, tend to defend rather than bid on (unless your side has 9 trumps.)See also Law of Total Tricks

Rule of Twelve

A calculation that can be used when it is assumed that opening leader has led the third highest card in a suit. By subtracting the pips on the card led from 12, the result is the number of cards in the other three hands that are higher than the one led. Third hand, for example, can then make inferences about declarer's holding in the suit by examining his own and dummy's holdings; likewise, declarer can make inferences about right-hand-opponent's holding in the suit.

Rule of Twenty

A widely used guideline of the Standard American Yellow Card (SAYC) bidding system which states that a hand may open bidding "normally" (that is, by bidding one of a suit) if the sum obtained by adding the combined length of its longest two suits to its high card points is twenty or more, but that weaker hands must either open with a preempive bid or pass. See also Zar points evaluation method.

Rule of Two

When missing two non-touching honors, it is normally superior to finesse first for their lower honor. In the following two example hands, three tricks or the maximum possible are needed. Template:BridgeSuitNSTemplate:BridgeSuitNS In the first hand, finesse the ♠10, not the ♠Q. Similarly in the second, lead the ♥2 and when West follows with the ♥9, it is best to finesse the ♥10. When one of the missing honors is the 10 the rule will not apply, as one does not normally finesse for a 10 on the first round.

Rule of Two and Three

A bidding guide suggested by Ely Culbertson, which counsels preemptors to be within two tricks of their contract if vulnerable, and within three if not. Few players now follow the Rule of Two and Three.

Ruling

A finding and decision by a tournament director or appeals committee.

Run

Rusinow leads

An agreement to lead the second highest of touching honors.

S

Sac

(Slang) Sacrifice. Also, "sack."

Sacrifice

To deliberately bid over an opponent's bid, hoping that the cost of a penalty will be smaller than the value of opponent's presumed successful contract.

Safety level

A level at which the partnership can normally assume, on the basis of the previous bidding, that its contract will succeed. It is the point below which the partnership prefers to explore even higher contracts. Also, "security level."

Safety play

A play that maximizes the chances for fulfilling the contract (or for achieving a certain score) by avoiding a play which might result in a higher score. Contrast with percentage play: the latter is the best play in a suit, while a safety play is the best line for the contract.

Sandbag

(Slang) To bid weakly or pass with good values, in the hope that the opponents will get overboard.

Sandwich

An overcall made after an opening bid and response by the opponents. The overcall is "sandwiched" between two hands that have each shown strength.

Short club

The natural opening bid of 1♣ when the suit contains only three cards. Usually employed by players using the five-card majors treatment for openings bids when holding a hand with opening values but lacking a 5-card major. When the hand contains two clubs and three diamonds, an opening diamond bid is preferred. Also, "short diamond."

Short-suit game try

By agreement, a bid of a short side suit after a single raise, hoping to reach game. For example, after 1♥ - 2♥, opener might rebid 3♣ with a singleton or void in clubs. The bid tells partner where high cards will be least useful, indicating duplication of values. It requests partner to take positive action with high-card strength outside that suit. Otherwise, the bid requests partner to sign off (in this example, by bidding 3♥). See help-suit game try and game try.

Short-suit points

In hand evaluation, points counted for singletons and voids.

Sound

A hand that is relatively strong for a call that is contemplated or that has been made.

Splinter bid

An unusual jump bid that by agreement shows a fit for partner's last-bid suit and a singleton or void in the bid suit. For example, a partnership could treat 4♣ in response to an opening bid of 1♠ as a splinter bid, showing a good hand with spade support and a singleton or void club. Compare with Fragment bid.

Strong notrump

An opening notrump that shows a balanced hand and 15-17 or 16-18 HCP. Compare with weak notrump. A partnership's choice between the use of a strong notrump or a weak notrump has extensive implications for its entire bidding system.

Strong pass system

A bidding system that mandates a pass by first (or second) hand to show what other systems would regard as an opening bid. A corollary is that if the next hand also passes, third (or fourth) hand must bid to keep the deal from being passed out.

Strong two-bid

Stub

(Slang) Part-score.

Sucker double

(Slang) An ill-advised penalty double, such as one based on HCP when the bidding warns of freak distributions.

Treatment

A natural bid that: (1) either shows a willingness to play in the denomination named, or promises or requests values in that denomination, and (2) by partnership agreement gives or requests additional information on which action could be based. If the treatment is an unusual one, it requires announcement to the opponents even though it is natural. For example, a partnership that plays Flannery usually agrees that a 1♠ response to a 1♥ opening bid shows five spades. So the 1♠ response to 1♥, while natural, is a treatment because by agreement it shows at least a five card suit. Contrast with convention, a bid that gives or requests information not necessarily related to the denomination named.

Trump squeeze

A squeeze that forces an opponent to weaken his holding in one of the threat suits enough that the suit can later be ruffed out.

Trump suit

(Often, simply "trumps.") By way of the auction, declarer and declarer's partner select the trump suit on the basis of their combined length and strength in the suit: the greater length to ruff more losers in the plain suits, and the greater strength to better control the play of the trump suit itself.

Such bids are limited only by the failure of the bidder to make a stronger or weaker bid; thus an Acol opening bid of one of a suit is limited by the fact that the opener failed to pass, to make a 2 level opening bid, or to make a pre-emptive opening bid.
