Kasparov v. Petrosian (After 35.__Kc6)
1. d4 d5 2. c4 dxc4 3. Nf3 Nf6 4. e3 Bg4 5. Bxc4 e6 6. h3 Bh5 7. Nc3 a6 8. g4 {This weakens white's kingside. This move is very aggressive and is a prelude to an exciting game.} 8... Bg6 9. Ne5 Nbd7 10. Nxg6 hxg6 {Black's kingside appears to have been destroyed but it gave black an open h-file for his rook.} 11. Bf1 {Retreating the bishop and placing it later on g7 where it can control the h1 -a8 diagonal.} 11... c6 12. Bg2 Qc7 13. O-O Be7 14. f4 {White continues his aggressive intentions on the kingside.} 14... Nb6 15. g5 Nfd7 16. Qg4 O-O-O {Black opted to castle on the queenside as white already gained a promising attack on the kingside.} 17. Rb1 {White now intends to pawn roll this b pawn.} 17... Kb8 18. b4 Nd5 19. Na4 f5 {This move practically thwarts white's intentions on the kingside.} 20. Qg3 Nxb4 21. Bd2 Nd5 22. Rfc1 {It is a basic principle to occupy open files with the rook. At this point, black's defensive skills will be ultimately tested.} 22... Ka7 23. Qe1 Ba3 24. Rc2 Qd6 25. Rb3 Qe7 26. Qe2 Rb8 27. Qd3 Bd6 28. Nb2 Rhc8 29. Nc4 Bc7 {Black truly defended very well against white’s attacking maneuverings.} 30. a4 b5 31. axb5 cxb5 32. Ra2 Kb7 33. Bb4 Qe8 34. Bd6 Ra8 35. Qb1 Kc6 {Here the king cooly defends itself against white's attack by indirectly attacking white's bishop.} 36. Rba3 {White now decided to lose a piece for the sake of continuing his attack.} 36... bxc4 37. Rxa6+ Rxa6 38. Rxa6+ Bb6 39. Bc5 Qd8 {Black's defensive skill is superb. White now is a piece down and his attack is about to end.} 40. Qa1 Nxc5 41. dxc5 Kxc5 42. Ra4 {Black has successfully defended against white's attack!} 0-1
