[Sicilian defence (B20)]
Sicilian (B22), Alapin's variation (2.c3)
2...d5 3. exd5 Qxd5 4. Bb5+ Nc6 5. Nf3 Bg4 6. d3 Bxf3 7. Qxf3 Qxf3 8. gxf3 Rc8 9. Be3 e6 10. c4 g6 11. Nc3 b6
12. O-O-O Bg7
At this point, tChess likes White's position slightly more (materially/tactically); however, Black likes his position. White's doubled isolated pawns are likely to be a weakness in the long term, but the open files may allow White some attacking chances in the short term.
13. Ne2 Ne7
tChess sees it virtually even after these moves.
14. d4 cxd4 15. Bxd4
Nxd4 may be slightly better for White.
15...O-O 16. Bxg7 Kxg7
Superficially, Black's king position looks like it could come under attack; however, White has no pieces which can directly attack Black's king on g7 and despite the open file, the position is solid defensively.
White unwittingly trades off his only piece (dark colored Bishop) that can attack Black's now well guarded King.
17. Rd7 Ra8 18. Rd6 Ne5 19. Rg1? Nxf3
If White plays f4, Black can take the pawn on c4; then if the Bishop captures the knight on c4, Rc8 would pin the bishop to the king, and win it with b5 (net effect is Black wins a pawn).
20. Rg3? Nh4?!
If Black plays Nxh2, the knight will become trapped. Black misses an immediate fork (which would win the exchange - knight for rook - with Nf5, forking both rooks [20...Nf5 21.Rxf3 Nxd6]). Instead, the move sets up an alternative fork on the next move.
21. Nd4? Nhf5
White misses the fork and Black ultimately wins the exchange of knight for rook.
22. Nxf5+ Nxf5 23. Rd7 Nxg3 24. hxg3 Rfd8 25. Re7 Kf6 26. Rc7 a5 27. Rb7 Rab8 28. Ra7 h5 29. a4 Rd6 30. c5 bxc5 31. Rxa5 Rbd8
Black's control of the open d-file is a big advantage.
32. Kb1 Rd2 33. f4 Rg2 34. Bc6 Rxg3 35. Rxc5? Rc8
White's capture allows Black to pin the bishop to the rook. Black's plan is to bring the king over; win the bishop; the only way for White to save it is to play b4; then b5, freeing up the rook; but then White's king would lose his only shelter and become more susceptible to mating threats.
36. Ka2 Ke7 37. Rc1 Kd6 38. Bh1?? Rxc1
White forgets about the pin and loses the rook instead of the bishop.
39. Bb7 Rc5
With all of Black's advantages, his only immediate concern is to make sure a pawn doesn't promote. This move and the next move squash any potential counterplay...
40. b3 Ra5 41. Be4 Kc5 42. Bc2 Kb4
Ka3 was White's only hope of building a fortress. Black's move limits the White king to the first two ranks.
43. Bb1 Rc5
With the outcome all but decided, White tries to give himself some stalemating chances, with his next two moves.
44. f5 gxf5 45. Bxf5 exf5 46. a5 Rg2+ 47. Kb1 Re5 48. Kc1 Re1#
0-1
