1. e4 c5 2. Nf3 Nc6 3. Bb5

Sicilian Defense: Nimzovich-Rossolimo attack after 3. Bb5.

Sicilian Defense: Nimzovich-Rossolimo attack after 3. Bb5.

Thus begins the Sicilian Defense, Nimzovich-Rossolimo attack. I don’t have a very good track record against this defense so I get unhappy when my opponents play this against me. I managed to draw this game, though.

a6 4. Bd3?

Sicilian Defense: Nimzovich-Rossolimo attack after 4. Bd3?

Sicilian Defense: Nimzovich-Rossolimo attack after 4. Bd3?

Most of my opponents capture the Knight here. Better was 4. Be2 because the Bishop on d3 blocks the advance of White’s d pawn.

d6 5. Ng5 h6 6. Qh5 Ne5

Sicilian Defense: Nimzovich-Rossolimo attack after 6... Ne5.

Sicilian Defense: Nimzovich-Rossolimo attack after 6… Ne5.

White is playing quite aggressively here. I believe that bringing the White Queen out this early in the game is premature. Black will gain tempi by attacking the White Queen. Note that Black is also threatening to capture the White Bishop on d3 and thus double White’s pawns.

7. Be2 Nf6 8. Nxf7 Nxf7 9. Qg6 Be6

Sicilian Defense: Nimzovich-Rossolimo attack after 9... Be6.

Sicilian Defense: Nimzovich-Rossolimo attack after 9… Be6.

White is down a pawn for a Knight here. White is also down in development. I think that White is playing more like a 1300 than an 1800 here!

10. f4 Kd7

Sicilian Defense: Nimzovich-Rossolimo attack after 10... Kd7.

Sicilian Defense: Nimzovich-Rossolimo attack after 10… Kd7.

On general principle I don’t like moving the Black King here and forfeiting the right to castle. However, I believe that it was necessary to break the pin on f7 even if it means giving back the sacrificed material. Black still has a lead in development here.

11. f5 Bxf5 12. exf5 Ne5

Sicilian Defense: Nimzovich-Rossolimo attack after 12... Ne5.

Sicilian Defense: Nimzovich-Rossolimo attack after 12… Ne5.

Now both sides only have two pieces developed. White has neglected his Queenside development for an attack on the Kingside. Black is cramped on the Kingside and his dark-squared Bishop is hemmed in by his own pawns. I would call this position unclear.

13. Qg3 Rg8 14. O-O g5

Sicilian Defense: Nimzovich-Rossolimo attack after 14... g5.

Sicilian Defense: Nimzovich-Rossolimo attack after 14… g5.

With his King stuck in the Center Black decided to advance on the Kingside and free up some space there. If 15. fxg6 then Rxg6 attacking the White Queen is good for Black.

15. Rd1 Qb6 16. Qb3 Qxb3 17. axb3 Bg7

Sicilian Defense: Nimzovich-Rossolimo attack after 17... Bg7.

Sicilian Defense: Nimzovich-Rossolimo attack after 17… Bg7.

Now Black has completed his development and can advance on either wing. White still needs to develop his queenside pieces.

18. Re1 (White keeps wasting time by moving this Rook around.) Raf8 19. Bc4 Nxc4 20. bxc4 h5

Sicilian Defense: Nimzovich-Rossolimo attack after 20... h5.

Sicilian Defense: Nimzovich-Rossolimo attack after 20… h5.

Black has more space on the Kingside and better placed pieces. Black continues his advance on the Kingside.

21. Nc3 g4 22. Re2 Re8 23. Na4 Kc6 24. Ra3 Nd7 25. Rb3 Rgf8

Sicilian Defense: Nimzovich-Rossolimo attack after 25... Rgf8.

Sicilian Defense: Nimzovich-Rossolimo attack after 25… Rgf8.

White has a Knight on the edge of the board attacking b6 and a Bishop that is hemmed in by his own pawns. Black is attacking the pawn of f5 and for some reason that I don’t understand White lets his have the pawn.

26. d3 Rxf5 27. Be3 Ref8

Sicilian Defense: Nimzovich-Rossolimo attack after 27... Ref8.

Sicilian Defense: Nimzovich-Rossolimo attack after 27… Ref8.

Black is up a pawn here and has his rooks doubled on the f file. Black also controls the long diagonal from a1 to h8. White now challenges control of the f file.

28. Rf2 Rxf2 29. Bxf2 b5 30. cxb5+ axb5

Sicilian Defense: Nimzovich-Rossolimo attack after 30... axb5.

Sicilian Defense: Nimzovich-Rossolimo attack after 30… axb5.

Black now advances on the Queenside too! Black has a slight space advantage here.

31. Nc3 c4 32. Rb4 Bxc3 33. bxc3 d5

Sicilian Defense: Nimzovich-Rossolimo attack after 33... d5.

Sicilian Defense: Nimzovich-Rossolimo attack after 33… d5.

Black is still up a pawn and one of White’s pawns is doubled. This has the effect of giving Black two pawns up. The White Bishop is slightly stronger than the Black Knight in this kind of open endgame.

34. Be3 e5 35. Rb1 Nc5 36. d4 exd4 37. cxd4 Ne4

Sicilian Defense: Nimzovich-Rossolimo attack after 37... Ne4.

Sicilian Defense: Nimzovich-Rossolimo attack after 37… Ne4.

Black has his pawns on light squares where the White Bishop cannot attack them and his Knight is on a good outpost square. Black also controls the f file. White has managed to undouble his pawn, but is still down one.

38. Re1 b4 39. Rb1 Kb5 40. Kh1 Nf2+

Sicilian Defense: Nimzovich-Rossolimo attack after 40... Nf2+

Sicilian Defense: Nimzovich-Rossolimo attack after 40… Nf2+

I am not sure why White allowed this check. Black wants White to capture the Knight here and give the Black Rook control of White’s second rank. White declined.

41. Kg1 Ne4 42. Re1 b3 43. h4 gxh3 44. cxb3 hxg2 45. bxc4+ Kxc4

Sicilian Defense: Nimzovich-Rossolimo attack after 45... Kxc4.

Sicilian Defense: Nimzovich-Rossolimo attack after 45… Kxc4.

Black is still up a pawn after the White capture on g2. Still, the passed h pawn was not enough to win this game.

46. Kxg2 Rg8+ 47. Kh3 Rg3+ 48. Kh4 Kd3 49. Bc1 Kxd4 50. Rxe4+!

Sicilian Defense: Nimzovich-Rossolimo attack after 50. Rxe4+!

Sicilian Defense: Nimzovich-Rossolimo attack after 50. Rxe4+!

This move surprised me. It wins the Black Knight and leaves Black with two passed pawns versus a Bishop. White cannot win this game with only a King a Bishop left but Black was unable to promote either passed pawn.

Kxe4 51. Kxg3 d4 52. Bg5 Kd3 53. Be7 Ke2 54. Bf6 d3 55. Bg5 d2

Sicilian Defense: Nimzovich-Rossolimo attack after 55... d2.

Sicilian Defense: Nimzovich-Rossolimo attack after 55… d2.

Black cannot hold onto the pawns here and thus draws.

56. Bxd2 Kxd2 57. Kh4 Ke2 58. Kxh5 1/2-1/2
