1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. g3 O-O 5. Bg2 d6 6. e4 Nbd7 7. Nge2 e5 8. O-O a6?! 8...exd4 and 8...c6 are the best options for Black here. 9. a4? 9.d5 punishes a6 the most, as now Black wants the pawn on a5 instead. 9... exd4 10. Nxd4 Nc5 11. h3 Re8 12. Re1 a5 Black has an extremely comfortable game. 13. Nb3?! 13.b3 followed by Bb2 looks best 13... Ncd7?! Why go back? 13...Nxb3 14.Qxb3 Nd7 is good for Black. 14. Nd5?! 14.Be3 Ne5 15.Qe2 Be6 16.Nd2 and White is very solid. 14... c6 15. Nxf6+ Bxf6!? 15...Qxf6 and Black is better because of the misplaced knight on b3. 16. Qc2 16.Qxd6 Ne5 and Black has more than enough compensation. 16... Qb6?! 16...Qe7 looks like a more natural square for the queen. 17. Be3 Qb4?! (17...c5) 18. Bd2 Qb6 19. Be3?! (Better is 19.Be3) 19... c5 20. Bd2 Ne5 21. Bc3 Be6 22. Nd2 Nd7?! 22...Qd8 23.b3 Nc6=/+. 23. Kh2?! I don't see what this does. 23. Bxf6 Nxf6 24.Qc3 Nd7 25.f4 and White has good play. 23... Bxc3 (23...Qd8) 24. Qxc3 24.bxc3 is an interesting alternative, trying to keep the black knight out of d4, as well as giving White an open d-file. 24... Ne5 25. b3 Qb4?! (25...Nc6) 26. Qxb4?! 26.Qe3! and White has good attacking chances because of the misplaced black queen. 26... axb4 27. f4 Nc6 28. Nf3 f5? 28...Kf8 29.Rad1 Rad8=. 29. exf5? 29.Ng5! is very strong here. 29...Nd4 30. exf5 Bxf5 31.Bxb7 Rab8 32.Bd5+ Kg7 33.Nf7! Nxb3 34.Nxd6 and White should be winning. 29... Bxf5 30. Rxe8+ Rxe8 31. Re1? This drops a pawn for nothing. 31. Rd1 Bc2 32.Rxd6 Bxb3 33.Nd2 Bc2 and the situation isn't 100% clear, though I still prefer Black. 31... Rxe1 32. Nxe1 Na5 33. Bd5+ Kf8 34. g4 Bb1 35. Nf3 Bc2 36. Nd2 b6 37. Kg2 Bxb3? 37...Nxb3 is much simpler. 38. Nxb3 Nxb3 39. Kf2 Ke7 40. Ke3 Nd4 41. h4 h6 41...h5! 42.f5 (42.gxh5 gxh5 43.Be4 Kf6-+) 42...gxf5 43.gxh5 b3-+. 42. Be4 Kf6 43. g5+ hxg5 44. hxg5+ Kf7 Now it isn't clear anymore. 45. Kd3 Ne6 46. Ke3 Nd4 47. Kd3 Ne6 48. Ke3 Nf8 48...b3 49.Bd3 b2 50.Be4 Nd4 51.Kd2 Kg7 52.Bd3 (52.Kc3 Ne2+ 53.Kxb2 Nxf4-+) 52...Kf7 53.Be4 and it is unclear how Black can break White's fortress. 49. Kd3 b3 50. f5?! 50.Kd2 Ne6 51.Ke3 and it is basically the same as the previous variation. 50... gxf5 51. Bxf5 Ne6 52. Kc3?! A stiffer defense would be 52.g6+ Kf6 53.Be4 (53.Bxe6 Kxe6 54.Kc3 Kf6 55.Kxb3 Kxg6 56.Kc3 Kf5-+) 53...Nf4+ 54.Kc3 Nxg6 55.Kxb3 Nf4 56.Kc3 Ke5 57.Bf3 and though Black should still be winning, it is a bit more difficult. 52... Nd4? 52...Nxg5 53.Kxb3 Kf6 54.Bc8 Ke5 55.Kc3 (55.a5 bxa5 56.Ka4 Kd4 57.Ba6 Nf3 58.Kxa5 Ne5-+) 55...Ke4 56.Bb7+ Ke3 57.Bd5 Ne4+ 58.Kb3 Kd4-+. 53. Be4 Ke6 54. Bd3 Ke5 55. Bb1 Nf3 56. Bd3? 56.g6 Kf6 57.Be4 (NOT 57.Kxb3 Nd2+ 58.Kb2 Nxb1 59.Kxb1 Kxg6 60.Kc2 Kf5 61.Kd3 Ke5 62.Ke3 d5-+) 57...Ne5 (57.. .Nd4 58.Bd3) 58.Kxb3 Nxg6 59.a5 bxa5 60.Ka4 Ne5 61.Bd5 Kf5 62.Kxa5 Kf4 63.Kb6 Ke3 64.Kc7 Kd4 65.Kxd6 Nxc4+ 66.Kc6=. 56... Nxg5 57. Kxb3 Kd4-/+ 58. Kc2 Nf3 59. Be2 Ne5 60. Kb3 Ke4 And Black won after a few more moves. 60...Nc6 and Na5 wins easily. 0-1 [Joshua Friedel]
