5...Nd6 · l'Hermet variation
[edit | edit source]Black attacks White's bishop. White's choices are between a quick draw or a drawish endgame.
White could take with the bishop first, 6. Bxc6. This leads to the famous Berlin Wall endgame, 6...dxc6 7. dxe5 Nf5 8. Qxd8+ Kxd8 where it is very hard for White to achieve more than a draw.
If White allows Black to take their bishop, 6. dxe5, Black doesn't actually win it and this leads to a big trade. 6...Nxb5 7. a4 Nbd4□ 8. Nxd4 Nxd4 9. Qxd4 d5. If White takes 10. exd6 e.p. Qxd6= this is the famous Berlin draw: neither side have anything better than to move their queens between the e- and d-files.
White could retreat the bishop, 6. Ba4 the Showalter variation, which allows Black to take the pawn 6...exd4 or push 6...e4 to where their pawn is defended by the knight. The game is thought equal either way.
The intermezzo 6. Bg5!? Be7 7. Bxe7 Qxe7 has been tried to avoid the queen trade after Bxc6 and postpone the endgame.
History
