1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be3 e6 7. Be2 ( 7. Qd2 ) 7... Be7 ( { Black might try the early wing play, but it's not likely to achieve much without follow-up piece play. } 7... b5 8. a4 b4 9. Na2 a5 ( 9... Nxe4 10. Nxb4 ) 10. c3 ) 8. a4 Nc6 9. O-O O-O 10. f4 ( { Another way to utilize Be3 it to try and achieve a bind on square b6. This is an older plan and is well known. } 10. Nb3 b6 11. f4 ) 10... Qc7 { Black prepares ...Nxd4 and ...e6-e5. } 11. Kh1 Re8 { While this move has the virtue of clearing for ...Be7-f8 and ...e6-e5 with some chance of play on the e-file, it also neglects the queen-side Bc8 & Ra8. } ( 11... Bd7 ) 12. Bf3 ( { Interesting or dubious I cannot say for certain: } 12. g4 Nxd4 13. Bxd4 e5 14. Be3 exf4 15. Bxf4 Be6 ) ( 12. Qe1 Nxd4 ( 12... Qb6 $2 13. Qd2 { and Black's queen must already retreat } ) 13. Bxd4 e5 14. fxe5 dxe5 15. Qg3 { pinning Pe5 and directly pressuring Kg8 } ) 12... Bf8 { Black doesn't fear White's plan and plans the counter strike ...e6-e5. } 13. Nb3 { but this takes pressure off Nc6, so Black can develop his queen-side freely. } 13... b6 14. a5 $5 bxa5 15. e5 dxe5 16. fxe5 Rd8 { Black takes this moment to transfer the rook to a more active square. } 17. Nd4 Nxd4 $5 { I'm not certain this was necessary, but it challenges White immediately and makes the game interesting. } ( 17... Bb7 18. exf6 Nxd4 19. Bxd4 e5 20. Bxe5 Qxe5 ) 18. Bxa8 Qxe5 ( 18... Nb3 19. cxb3 Rxd1 20. Rfxd1 Nd7 ) 19. Bg1 Be7 { White's queen is feeling the pinch as any move from Nd4 discovers an attack on Qd1 and the queen is tied to Pc2. } 20. Nd5 { This is a desperate measure for certain. It's a "trick" to trade Nc3 for Nd4, which helps White block the d-file too. } 20... Nxd5 21. Bxd4 Qb8 22. Qh5 f5 ( 22... g6 23. Qf3 { still forces ...f7-f5 } ) 23. Bxd5 Rxd5 { Black has a bishop plus two pawns for White's rook, but Black's doubled a-file pawns aren't so great. I suppose a lot depends upon whether White can find a way to utilize all his pieces. If Black can shut out one or two of White's pieces then his pawns might have a say in the outcome. Pg7 is an obvious target, but ...e6-e5 could shut out Bd4. } 24. Qe8+ Bf8 25. Bc3 Qb7 26. Rxa5 { I don't see how trading Pb2 for Pa5 could be good. It makes Black's Pa6 a passer. } ( 26. Rae1 ) 26... Bd7 27. Qh5 Rxa5 28. Bxa5 Qxb2 29. Qe2 Qa2 { defending against Qxe6+, so Bd7-b5 is a real threat AND threatening Ba5 } 30. Qd2 Bc6 31. Rc1 Qc4 { quickly preventing c2-c4, so it's only Black's Pa6 which might have a good chance of advancing. Still, it's very close to equal. } 32. c3 Be7 33. Bd8 Bc5 34. Bg5 h6 35. Be3 Be7 { Black avoids trades because he'll need both bishops to guard the many squares necessary for either an offense or a defense to work. } 36. Rb1 a5 37. Kg1 a4 38. Bd4 a3 39. Ra1 Bd5 40. Qe3 a2 { This ensures Black all the winning chances. Ra1 won't be able to do anything offensively so long as Pa2 threatens to advance. } 41. Qg3 Bf8 ( 41... g5 $4 42. Qe5 ) 42. Rc1 Be4 { threatening ...Be4-b1 to enable ...a2-a1=Q } 43. Qe1 { White is essentially offering to trade Black's bishop and pawn for rook, to play the ending one pawn down, but with much better drawing chances. Black, on the other hand, has the threat of advancing Pa2 and more pawns on the king-side. So, he might attack Kg1 or threaten to advance Pe6 while using Pa2 as a constant diversionary threat. } 43... Bd6 44. h3 Qd3 45. Ra1 Qc2 { White can't find an adequate mechanism to prevent Black's many threats. } 0-1
