Benko GambitA59

Silva B. (1908)
Shabazz D. (2093)

Robert Fromke Memorial (5)

Game against Ben Silva, a relatively late bloomer in chess, but very tricky. The only issue with him is his tendancy to be impatient at times. He usually wins games against me in blitz, but in longer time controls, it's important to have a good pace.

1. d4 c5 2. d5 Nf6 3. c4 b5!? The Benko Gambit. It is still a respected defense and new ideas are evolving all the time. It is a favorite of many top players. 4. cxb5 a6 5. bxa6 g6 6. Nc3 Bxa6 7. e4 One of the more practical lines. 7... Bxf1 8. Kxf1 d6 9. g3 9. g4!? was a line that was considered an Anti-Benko system that Yasser Seirawan used successfully a couple of times. 9... Qc8 10. h3 Bg7 11. Kg2 O-O 12. Nge2 Na6 13. Be3 Qb7 14. Qd2 Nc7 15. f3 Rfb8 16. b3 Nb5 17. Rac1 Nd7 18. Nxb5 Qxb5 19. Rc2 Ne5 20. Nc1 Qa6 21. Rf1 Rb4 22. Rf2 Rab8 23. Qe2 Qxe2 24. Rfxe2 h6 25. f4 Nd7 26. Kf3 R4b7 27. Nd3 Rf8 28. Bd2 f5 29. exf5 gxf5 30. Rxe7 fxg4+ 31. hxg4 Rf7 32. Re6 Bf8 33. f5 h5 34. Bg5 hxg4+ 35. Kxg4 Rg7 36. Rh2 Rb5 37. f6 Rf7 38. Kf5 Nb6 39. Nf4 c4 40. bxc4 Nxc4 1-0 Seirawan,Y (2595)-Gurevich,D (2535)/New York 1987/CBM 002 9... Bg7 10. Nf3 Nbd7 11. Kg2 O-O 12. Re1 Ra6!? 13. Bf4 Qa8 13... Qb6 14. Qe2 Qb7 15. Rab1 Rfa8 16. a4 Rb6 14. Qd2 Nb6 The idea is obvious. Exert pressure down the a8-h1 diagonal with ...e6 and/or ...f5. Typical Benko ideas. 15. Rab1 Rb8 16. e5 dxe5 16... Nfxd5! 17. exd6 exd6 18. Bxd6 Rd8 19. Nxd5 Nxd5 20. Bxc5 Nc3 17. Bxe5 Rd8 During the post-mortem, Ben thought this was a mistake, but it was the correct choice. 17... Nc4 was another move I considered and probably decent. 18. Qd3 Nxe5 19. Rxe5 Rd6 18. Bc7?! Rd7 19. Bxb6 Rxb6 20. Qe3 Qa5?? Clear blunder. This was a move played without a purpose other than guarding c5, but the queen belongs on the diagonal. Black can press with 20... Nxd5! 21. Nxd5 (21. Qxc5? Nxc3 22. Qxb6 Nxb1) 21... Qxd5 22. b3 (22. Rbd1 Bd4) 22... Qa8 23. Kg1 Houdini(23. a4 Re6 24. Qxc5 Rd3 25. Re3 Rexe3 26. fxe3 Rd2+!) 21. Ne5 I knew this move would cause lots of trouble, but I found the best try. 21... Nxd5 22. Nxd5 ... now the game takes an interesting turn after my next move... which was not good. 22... Re6? not good but probably the most complicated. 22... Rxd5 23. Nc4 not good either. 22... Qa8 23. Nxd7 Qxd5+ 24. Kg1 Qxd7 25. Qxe7 Qxe7 26. Rxe7 23. Nxd7! Best. This gives white a lasting initiative with two rooks and two passed pawns. However, the black queen would earn her paycheck in this game. 23. b4 23... Rxe3 24. Nxe3 24. Rxe3! 24... Qc7 The knight is trapped, so white has to playing actively to coordinate pieces. 25. Red1? Unnecessary. White has allowed black a chance to complicate matters. 25... Bd4 26. Nxc5 Bxc5 27. Nd5 Qe5 27... Qa7! with good play. After 28. Rd2 Qxa2 29. Rc1 Qa5 30. Rdc2 Bd6 it's hard for white to make any use of his doubled rooks. 28. b4 Bd4? No excuse. I was concerned about white's pawns and I wanted to create threats, but this move gives white the advantage again. 28... Ba7 29. b5 Bc5 29. Nxe7+ Kg7 30. Re1 Qf6 31. Re2 Be5 Trying to confuse him, and.. . 32. f4? It worked! 32. Nd5! is winning. 32... Bd6 33. Nd5 Qd4 White's pieces cannot get coordinated and this spells trouble against a fleet-footed queen and an exposed white king. 34. Ne7 Bxb4 Now I was completely relieved as I knew the remaining passed pawn would be no problem. 35. h4? Final mistake. 35. Rxb4!? with an idea of a fortress. 35... Bxe7 36. Rxe7 Qd5+! I saw that this wins a rook in all variations. Wow! 37. Kf2 37. Kh2 Qxa2+ 37. Kh3 Qf5+ 37. Kf1 Qd3+ 37. Kg1 Qc5+ 37... Qxa2+ 38. Re2 Qxb1 Now it's over. Just need a bit of technique. 39. Re3 Kf6 40. Re5 h6 41. g4 Qb2+ 42. Kf3 Qxe5! I decided to do it the most concrete way. I calculated this to an easy win. 43. fxe5+ Kxe5 44. Ke3 f5 44... g5 45. hxg5 hxg5 46. Kf3 Kd4 45. gxf5 Kxf5 46. Kf3 h5 47. Kg3 Ke4 48. Kg2 Kf4 49. Kh3 Kf3 0-1 [Shabazz D.]
