[Event "Bled"] [Site "?"] [Round "0"] [White "Olafsson"] [Black "Petrosian"] [Result "0-1"] [ECO "C16"] [Opening "French: Winawer, Advance Variation"] 1. e4 e6 2. d4 d5 3. Nc3 Bb4 4. e5 Qd7 5. Qg4 f5 6. Qg3 b6 7. h4 Bb7 8. Bd3 Nc6 9. Nge2 O-O-O 10. Bd2 Nh6 11. a3 Be7 12. Bb5 {White pins the Black knight on c6. 12.Qxg7 Ng4 would put the White queen in serious danger of being trapped.} 12... Rdg8 {12...a6 Although trying to break the pin looks natural, White has a strong reply. 13.Bxc6 Bxc6 14.Qxg7 Ng4 15.Bg5 allowing White to take advantage of Black's dark squared bishop. 15...Bxg5 16.Qxd7+ Rxd7 17.hxg5} 13. Qd3 Nf7 14. O-O-O {14.Nf4 would be better, threatening a fork.} 14... Kb8 { A very deep and yet simple move. Petrosian's idea is to break the pin, on the Black knight, with 15...Qc8.} 15. Nf4 Qc8 {Although Black's position looks cramped, he is almost ready to begin striking at White's center. The target, as is so often the case in the French Defense, is the pair of pawns at d4 and e5.} 16. Nce2 Ncd8 17. Qb3 {17. Qb3 is a miscalculation which costs White a pawn and the game. Better was 17. c3. 17.c3 c5 18.Kb1 Although, Black would still stand better due to, his play on both flanks.} 17... c6 18. Bd3 c5 { Finally! Black achieves the goal of the opening and breaks down White's center. } 19. dxc5 Bxc5 20. Nh3 Nxe5 {Black has won a very valuable center pawn. Given Petrosian's technique, it is good enough for the victory.} 21. Bf4 Ndf7 22. Bb5 {22.Qc3 Attacking the pinned knight again. would be met adequately by 22...Bd6. } 22... Ka8 { Black gets his king out of the pin. Which allows his knight on e5 to move.} 23. Nd4 Ng6 24. Qa4 {An unsound sacrifice which ends the game. Still, White had no good response to Black's threat of pawn e5.} 24... Bxd4 25. Bd7 Qf8 26. Rxd4 e5 27. Rb4 exf4 28. Rxb6 Nfe5 29. Rxb7 Kxb7 30. h5 { 30.Qb5+ Kc7 when Black would soon realize his material advantage.} 30... Qd6 31. hxg6 Qxd7 32. Qxf4 Nxg6 {White resigned as Black is up a whole rook.} 0-1
