Queen's Gambit DeclinedEdit

3.Nc3Edit

After building a pawn center with his first two moves, White begins the development of his minor pieces with 3.Nc3. On c3, the knight controls the d5 and e4 squares. White would like to play e4 at some point to gain even more presence in the center, and 3.Nc3 facilitates this break.

White's dark-squared bishop will likely go to g5 after Black plays Nf6, but of course this is not possible immediately because of 3...Qxg5. Moving the bishop to a different square on move 3 would simply lose a tempo if it later went on to g5, so it is best to develop a knight here instead. There are sound systems involving Bf4, but it is not wise to commit to a Bf4 system so early. Thus 3.Nc3 and 3.Nf3 are the most sensible options.
