Two Knights Defence - Classical Variation
edit4...exd4
editBlack plays exd4. Black is a pawn up but has a number of weaknesses the square e5, the Knight on f6 that can be pinned and also the weak f7 square. This all adds up to giving White a number of options. They are.
- 5. O-O the classical variation.
- 5. e5 the modern variation.
- 5. Ng5 a misguided direct attack on f7.
- 5. Nxd4 rather normal move.
- 5. Bg5 pinning the Knight, but the pin can soon be undone, leaving no advantage for White.
- 5. Qe2 this supports e5, although e5 can be played immediately anyway.
- 5. c3 fails to 5...Nxe4 where Black has the nice d5 available and time to block any pins on the e-file against the King.
