Black: GM Arthur Bisguier
2004 Emory/Castle Grand Prix
Round 5

In the final round I was once again paired with a grandmaster, this time I had the White pieces against GM Arthur Bisguier. While Bisguier's rating has dropped considerably in recent years, his vast experience still makes him a dangerous opponent. 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. cxd5 exd5 5. Bg5 c6 6. Qc2 Na6 7. e3 Nb4 8. Qd2 Bf5 9. Rc1 a5 10. a3 Na6 11. f3 This seems to be a new move in this position. It is probably better to play the immediate 11. Nge2, a flexible move that has been played by players as disparate as Shirov and Petrosian. I observe that I twice played f3 in this tournament before Nge2, which may indicate lazy thought. Just sort of saying, "well, I'll play f3 so I don't need to worry about ...Ne4." Since Black's knight maneuvers had weakened his control over e5, I also considered the active 11. Nf3 Be7 12. Ne5 O-O 13. f4 but decided this wasn't so great with his bishop already controlling e4. 11... Be7 12. Nge2 Nc7 13. Ng3 Bg6 14. Bd3 Ne6 15. Bxf6 Bxf6 16. Nf5 O-O 17. O-O c5 This nice move leaves Black with no particular problems. 18. Ne2 18. dxc5 Nxc5 is very comfortable for Black. The weakness of the b3 square means White will have to play with 2 knights against two bishops. The only other alternative is to try to hold up Black's queenside play with 18. Nb5!? c4 19. Bb1 Qd7 20. a4 18... c4 Now, the plans for each side are pretty clear. Black has firm control on the queenside and has restrained any central break by White. White has to go for the kingside attack. 19. Bb1 b5 20. g4 Re8 This move surprised me a bit. He wants to make f8 available for his knight, but moving the rook may be mistimed. Since the b-file will eventually be opened this rook may find better work there, so I think the immediate 20... Rb8 was better. 21. Neg3 Rb8 22. f4 so f2-f3 ended up not serving much of a purpose 22... Bxf5 23. Nxf5 b4 24. axb4 Rxb4 25. g5 Be7 26. Qg2 Since ...Nf8 will neutralize attacks along the b1-h7, I turned my focus to the g-file. 26... Nf8 27. h4 Qd7 28. h5 Qe6 a somewhat dangerous move. He wants to provoke Rf3 to relieve the pressure on the d5 square from the White queen, but on e6 the queen is potentially vulnerable to the move f5. 29. Rf3 Reb8? On the surface this doesn't look like a mistake since he attacks the b-pawn with tempo, but 29... Qb6 was the consistent move. Now I get to finish the game tactically.

30. Nh6+! gxh6 30... Kh8 31. f5 is no better 31. gxh6+ Ng6 32. f5 highlighting the problem of the black queen's position. 32. hxg6 fxg6 33. f5 was also strong 32... Rxb2 Moving the queen allows a mating attack. For example, 32... Qd6 33. fxg6 fxg6 34. hxg6 hxg6 35. Bxg6 Kh8 36. Rf7 +- He never has time to take on b2 in these lines since White will capture or move to h7 with double check. 33. Qxb2 Rxb2 34. fxe6 Nh4 34... Nh8 35. exf7+ Nxf7 (35... Kf8 36. Bxh7) 36. Bxh7++- 35. Rxf7 Bg5 36. Rg7+ Kf8 37. Rf1+ [1:0] This win was sweetened when all of the games on other boards went the way I needed them to in order to emerge as clear first in the 2200-2400 class.
