Bh3 as in the game Domínguez Pérez – Kamsky, 1st SportAccord World Mind Games; Blindfold’s Event; 北京 (Beijīng) 2011. 11. f3 0-0 12. g4 b4? A bad move, as the White’s Knight is very happy to move to the Kingside for assisting in the attack. A possibly better idea was 12. ... hxg4 13. h5 gxh5 14. Ne2! gxf3 15. Ng3 c5, where Black can still hope to get some counter-play. 13. Ne2 hxg4. Black has no time for 13. ... a5 on account of 14. Ng3! hxg4 15. h5! with consequences very similar to the game. 14. Ng3! gxf3? This only helps White’s attack, but even after 14. ... c5 15. h5 gxh5 16. Nxh5 (16. Rxh5? is met by 16. ... cxd4) 16. ... Nxh5 17. Rxh5 Nf6 18. Rh4 White retains a powerful initiative. 15. h5! Nxh5. A lesser evil would have been 15. ... gxh5 16. Rxh5 c5 (16. ... Nxh5 transposes to the game) 17. Rh4 with the same point as mentioned above.


16. Rxh5! White sacrifices the Exchange to shatter Black’s defence. 16. ... gxh5 17. Nxh5 Nf6 18. Qh2 Re8 19. Bd3 e5 20. Nxg7 Kxg7 21. Nh7! A pretty coup. 21. ... Ng4. On 21. ... Nxh7 22.
