Round 3 Board 1

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Nxe4 6. d4 b5 7. Bb3 d5 8. dxe5 Be6 9. Nbd2 Nc5 10. c3 Nxb3!?

Although I achieved a reasonable position against Ron Burnett, I wasn't keen to try 10... Nd3 11. Qe2 Nf4 12. Qe3 g5 again, but was still in the mood for an alternative to the usual moves. 11. Nxb3 Be7 12. Nfd4 Qd7 12... Nxd4 is also playable. 13. Nxc6 Qxc6 14. Be3 O-O 15. Nd4 Qd7 16. b4 f6 It might be a bit better to try 16... c5 17. bxc5 Qc7 17. exf6 Bxf6 18. Re1 Bf7 18... Rae8 is another way to go, but I was looking at the idea a6-a5-a4 19. Qd2 a5 20. a3 a4 To take away the maneuver Nd4-b3-c5. This is consistent with Black's previous move, but it would be better to first prevent the exchange of dark squared bishops with 20... h6 with an approximately equal game. 21. Bg5 Bxd4?! 21... Bxg5 22. Qxg5 Rae8 would still be about equal. I was worried that the bishop would be bad against the knight because of the pawn structure, but the opposite colored bishop position is worse since White's bishop has a great deal of scope. White now operates unobstructed on the dark squares and Black lacks play on the light squares. 22. cxd4 Rae8 23. Rec1 Re6 24. Bf4 c6 25. Rc3 Rg6 26. Rac1 Be8 27. Re1 Qf7 28. Bg3 Bd7 29. h3 Re8 30. Be5 Qf5 31. Kh2 Rf8 32. f3 I was quite impressed by the way Sergey used his kingside pawns on the light squares to further restrict my bishop. .. h5 33. g4 hxg4 34. hxg4 Kf7

I wanted to get my rooks to the h-file, but since the Rg6 is no longer well placed and Rf8 is already reasonably placed 34... Qf7 followed by 35...Rh6 deserved more consideration. 35. Kg2 Not 35. gxf5?? Rh8+ 36. Qh6 Rhxh6# or 35. Kg3? Rxg4+ 35... Rh8 36. Bg3 Qf6 37. Rce3 Re8 This abandoning of the h-file shows the flaw in the logic of Black's 35th move. 38. Rxe8 Bxe8 39. Qf2 Bd7 It may be slightly better to prevent Bh4 by 39... Rh6 40. Qe3 Qd8 40. Bh4 Qd6 41. Re7+ Kf8 42. Qg3 Qxg3+ 43. Kxg3 Be8?! Black's position has slowly drifted away. I thought the rook could become active via the h-file, but it is too slow. The last chance may have been to temporarily hold up f4 with 43... Be6 intending after 44. Rc7 Bf7 45. f4 to try to give the rook some prospects on the e-file with 45... Re6 44. f4 Rh6 45. f5 Rh8 45... Rxh4 46. Rxe8+ and White easily wins the pawn ending since his king can stop the d-pawn after the ...c5 break. 46. Rc7 Rh6 47. Be7+ Kg8 48. g5 Rh1 49. Rc8 Re1 50. Bd6 Kh7 51. Be5 Rg1+ 52. Kf4 Rf1+ 53. Kg4 Rg1+ 54. Bg3 Bf7 55. Rf8 55. g6+ Bxg6 56. fxg6+ Kxg6 57. Rxc6+ is also a straight forward win, but White doesn't even have to allow Black that much. 55... Bg8 56. g6+ Completing the domination of the black bishop by White's pawns 56...Kh8 57. Rc8 c5 Unfortunately, Black's c-pawn prevents a stalemate trick with 57... Rxg3+ 58. Rxc5 Ra1 59. Be5 Rg1+ 60. Kh4 Rh1+ 61. Kg3 Rf1 62. Rc7 [1:0]
