16. ... h6? A weak and weakening move that gives White an imposing advantage. Black’s best seems to be 16. ... f5 17. exf6 exf6 18. Bb2 Kf7 so as to oppose Rooks on the open e-file.
17. Bb2 Nd4 18. Bxd4 cxd4


19. e6! Bf6. If 19. ... fxe6 then 20. Nh4! followed by Re1-e4, Qd1-e2 and Ra1-e1 and White will soon regain her Pawn with consequences similar to those of the game.
20. exf7 Kxf7 21. Re4 Rd6 22. Qe2 Re6. A bad move, but maybe there were no good ones.
23. Re1 Rxe4 24. dxe4 Qb5


25. e5 Qxe2 26. Rxe2 Bg7 27. Nxd4. The d4-Pawn has fallen, but much worse things await Black.

10. f4 b6 11. Bd2!? Bb7 12. Qf3 Nbd7 13. Rae1 0-0. 13. ... g6 will also bring good luck to 侯逸凡 (Hóu Yìfán): 14. Qh3 h5 15. Nd1! b5 16. Ba5! Qb8 17. Bc3 b4 18. Bxb4 Bxe4 19. Bc3↑ 侯逸凡 (Hóu Yìfán) – Vitiugov, 6th Aeroflot Open, Moscow 2007.
14. Qh3 g6? Deep in her heart, White was asking nothing else than a breakpoint! More appropriated was 14. ... Rad8 15. g4 Nc5 16. Nxc5 dxc5 17. g5 Nh5 18. f5 Qd7 19. Nd5 exd5 20. cxd5 g6 21.

1. e4 e6 2. d4 d5 3. Nc3 Bb4 4. e5 c5 5. a3 Bxc3+ 6. bxc3 Ne7 7. h4. One of the sharpest lines against the Winawer French besides 7. Qg4.
7. ... Qc7. After 7. ... Nbc6 8. h5 h6 9. Qg4 Rg8 10. Bd3 white is better, as played already in 1937 in the game L. Steiner – Koshnitzky.
8. Nf3. The Pawn sacrifice 8. h5 cxd4 9. cxd4 Qc3+ 10. Bd2 Qxd4 11. Nf3 Qe4+ 12. Be2 Nf5 is not entirely clear.
8. ... Nbc6 9. h5 h6 10. Bd3 Bd7. Avoiding a trap: 10. ... cxd4 11. cxd4 Nxd4? 12. Nxd4 Qc3+ 13. Qd2! Qxa1 14. c3 Nc6 15. Nb3 winning the Black Queen.
11. 0-0 0-0-0. 11. ... c4 12. Be2 f6 was played before.
12. a4 Nf5. Black should have either attacked the center with 12. ... f6 or blocked it with 12. ... f5.

14. Bxc5 fxe5 15. dxe5 Qa5. After 15. ... Nxe5 16. Nxe5 Qxe5 (on 16. ... Qxc5 17. Bxf5 exf5 18. Nf7 wins) 17. Bxa7 Qxc3 18. a5 Bc6 19. Qg4 White has a clear edge.
16. Bd4. Consolidating, but 侯 (Hóu) could have played the sharp 16. Bb4!? Nxb4 17. cxb4 Qxb4 18. Bxf5 exf5 19. Nd4 Rhe8 20. Re1 Be6 21. Rb1 with a powerful attack.
16. ... g6? Trying to open files against the White King, Black makes a fatal mistake. 16. ... Rhf8 is better.
17. hxg6 Rhg8. After 17. ... Nce7 18. Nd2 Nxg6 19. Nb3 Qc7 20. Bxf5 exf5 21. e6 Bxe6 22. Bxh8 White should win.
18. Bxf5! exf5 19. Nh4 Ne7. 19. ... Be8 is met by 20. Qh5!.


20. e6! White opens the e-file and preserves the g-Pawn.
20. ... Bxe6 21. Qe2 Rd6 22. Qe5 Rc6. After 22. ... Qc7 23. Qf6 Nc6 24. Rfe1 Nxd4 25. cxd4 Qg7 26. Qxg7 Rxg7 27. Re5 white has a decisive advantage.
