11. ... b4 12. axb4 Nxb4 13. g4 Be7 14. g5 Nd7 15. h4 Nc5 16. Kb1


16. ... d5? A theoretical blunder which betrays 侯逸凡 (Hóu Yìfán)’s scarce or inexistent preparation. All the more surprising is that the “stem game” is a very famous one: 16. ... Rb8 17. h5 0-0 18. g6 Bf6! 19. Rdg1 Ba8! 20. Bg5? (⌓ 20. h6 fxg6 21. hxg7 Bxg7 22. Bh6) 20. ... Be5 21. gxh7+ Kxh7 22. Nb3? (⌓ 22. Be3) 22. ... Nxc2! 23. Nxc5 Na3+ 24. Ka2 Qxc5 25. Na4 Nc2! 26. Kb1 Qa3 0 : 1 M. Adams – Kasparov, 22nd Torneo Internacional de Ajedrez Ciudad de Linares, Linares 2005.
17. exd5 Nxd5 18. Nxd5 Bxd5


19. Nf5! Rd8? Of course after 19. ... exf5 20. Qxd5 0-0 21. Qxf5 Black has nothing to be happy about, but the text is, if possible, even worse for her. The rest is easy.
20. Nxg7+ Kf8 21. Qc3 Rg8 22. Nh5 Qc6 23. Nf6 Bxf6 24. Bxc5+ Be7 25. Bxe7+ Kxe7 26. Qf6+ Ke8


27. c4 Be4+ 28. fxe4 Qxe4+ 29. Ka1 Rxd1+ 30. Rxd1 1 : 0.
