Nakhmanson Gambit, Kf6 Defence, Queen Capture
[edit | edit source]9. Qxe4
[edit | edit source]White now has the very simple threat of Bg5+ winning the Black queen.
Let's look at some obvious defences that don't work:
- 9...h6?? 10.Nh4! sees the White queen invade on g6 in combination with a rook on e1, for example
- 10...g5 11.Qg6+ Ke5 (Ke7 12.Nf5#) 12.Re1+ Kd5 13.Qe4+ Kc5 14.Be3+ Kb5 15.a4+ 1-0
- 10...d6 11.Qg6+ Ke7 12.Re1+ Ne5 13.Bf4 Kd7 14.Bxe5 Qxh4 (or 14...dxe5 15.Rxe5 with threats of Qf7+, Qe6+ and Qg4+) 15.Bf6! 1-0
- 10...Ne7 (to control g6 and stop that from happening) 11.Qf4+ Ke6 12.Re1+ Kd5 13.Re5+ with mate in 2
- 9...d5?? 10.Bg5+ Kf7 11.Qf4+ 1-0
- 9...Ne7?? would be the correct move against 9.Re1, but here it fails quickly to 10.Qf4+ when 10...Nf5 11.Qg5+ wins the queen anyway, and 10...Kg6 or 10...Ke6 allow the f3-knight in with check.
The correct move is to indirectly control g5 with 9...Be7! which also vacates the f8 square on which the Black king can shelter from e-file checks. Black's Plan A is to make an immediate dash for f8, but this isn't always possible.
