Round 2, Board 7

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f4 O-O 6. Nf3 a6 7. a3 Once again trying Vaisser's suggestion, as I did a couple of years ago against Wojtkiewicz. Looking back on my notes to that game, I wasn't all that satisfied with the result of the opening, and the same is true of this game. Perhaps 7. Bd3, as Matthew Marsh played against me in the 2003 Knoxville City Championship deserves a chance. 7... b6 8. Bd3 c5 9. d5 b5 10. O-O Afterwards, he suggested the immediate push 10. e5 White could also try the Benko Gambit-like position after 10. cxb5 axb5 11. Nxb5 (11. Bxb5 Nxe4 is a standard equalizing tactic) This is an interesting position. White will probably have to lose a tempo retreating Nb5-c3 and a3 has weakened the b3 square. On the other hand, with f4 already in White is much further along in the center than he typically is in the Benko and Black spent two moves to play b5. 10... bxc4 11. Bxc4 Nbd7 12. e5 I chose to go for rather murky complications rather than 12. a4 Nb6 13. Bd3 a5 when I thought Black was fine. 12... dxe5 13. fxe5 Ng4 14. e6 fxe6 15. h3?! Now Black gains a nice edge. The standard ploy of 15. Ng5 doesn't work out so well in this position after 15... Bd4+; Best seems to be 15. dxe6 to meet 15... Nde5 with 16. Bd5 15... Nde5 16. Nxe5 Rxf1+ A good intermezzo either diverting a White piece from d5 or forcing the awkward 17. Kxf1. If instead, 16... Nxe5 white plays the in between 17. Rxf8+ 17. Qxf1 Nxe5 18. Ba2 Since White trades the light squared bishop on the next move anyway, it was better to start activating the undeveloped queenside with 18. Be3 18... c4 19. Bxc4 This maintains material equality, but now Black's unopposed light squared bishop becomes a monster. 19... Qb6+ 20. Kh1 Nxc4 21. Qxc4 Bb7 22. Bg5 Rc8 on 22... Qxb2 my intention was 23. Rb1 but 23... Bxd5 looks very good for Black. He decided to try to avoid complications and just play on his positional trumps. 23. Qg4 Rf8?! 23... Qxb2 is still good. The Black king is a bit open, after 24. Rb1 Qxc3 25. Rxb7 Qe1+ 26. Kh2 Be5+ 27. Bf4 Bxf4+ 28. Qxf4 exd5 but it certainly isn't two pawns worth of compensation.

24. Bxe7? Remarkably, White has a resource here 24. Qxe6+ Qxe6 25. dxe6 Rf2 looks horrific, but 26. Rd1! seems to give White a realistic chance to hold the game, for example 26. Rd1 h6 (26... Bf8 27. Nd5) 27. Bxe7 Rxg2 28. Rd8+ Kh7 29. Rd7 Bc6 30. Rd6 Bf3 31. Rd3 with a repetition. 24... Rf5 25. Rd1 25. d6 Qxb2 26. Rd1 Bxc3 27. d7 Ba5 28. d8=Q+ Bxd8 29. Rxd8+ Kg7 and the opposite colored bishops work in Black's favor. 25... exd5 26. Bh4 d4 27. Ne2 27. Ne4 is nominally better, but Black is still winning. The text allows a nice finish. 27... h5 28. Qg3 Be5 29. Qd3 Qc6 30. Rg1 Rf1 31. Qb3+ Kh8 Moving the king to the 7th rank would allow Qxb7 with check followed by Rxf1 and White can grovel a little longer. [0:1]
