[Event "Montreal"] [Site "Montreal"] [Date "1979.06.17"] [Round "12"] [White "Karpov, Anatoly"] [Black "Larsen, Bent"] [Result "0-1"] [BlackElo "2620"] [ECO "B01"] [TimeControl "0"] [WhiteElo "2705"] { A strong world champion falls to the Scandinavian Defense played by a Scandinavian. The outcome of this game is determined primarily by rook play. Black's rooks and other pieces are wonderfully coordinated. } 1. e4 { B01: Scandinavian Defence } 1... d5 2. exd5 Qxd5 3. Nc3 Qa5 4. d4 Nf6 5. Bd2 Bg4 6. Be2 Bxe2 7. Ncxe2 Qb6 8. Nf3 Nbd7 9. O-O e6 10. c4 Be7 11. b4 O-O { 11... Bxb4? is no good 12. Rb1 pins it against black's queen. 12... a5 13. a3 and the bishop falls. } 12. a4 c6 13. Qc2 Qc7 { 13... Bxb4? is still no good because of 14. a5. } 14. Rfe1 b6 15. a5 { White gets more space. However, there is a fine line between pawns that are aggressively poised and over extended. } 15... Rfb8 16. a6 b5 17. c5 { This push gains space, but creates a wonderful post for black's knights on d5. } 17... Nd5 { A comfortable square for the black knight. } 18. Nc1 Re8 19. Nd3 Rad8 20. g3 { Prevents intrusion on f4 and h4. } 20... Bf6 21. Re4 Nf8 22. h4 Rd7 23. Kg2 Red8 24. g4 Re8 25. g5 { White wins space now on both sides of the board. } 25... Bd8 26. Nfe5 Rde7 27.

Re4 trying to hold on to h4, is a better option for white in this line. } 36... Bxh4 $1 { A surprise sacrifice tactic. } 37. Qe2 { If instead, 37. Bxh4 then Rxd3. The rook is immune due to Nf4+ forking king and queen. } 37... Bxg3 38. fxg3 Qd7 39. Qxf3 { A tough decision -- can white coordinate his Rooks before black activates his Queen? } 39... Rxf3 40. Kxf3 Nxb4 $1 { The knock-out blow. Now if 41. Nxb4 then 41... Qxd4 with a triple attack and no where to hide. } 41. Rd1 Qxd4 42. Re4 Qd5 43. Nf2 Qh5+ 44. Kg2 Nd5 { 44... Nxa6 is also quite playable. } 45. Rxe6 h6 { Black attends to his King's safety. } 46. Rd3 Kh7 47. Rf3 b4 48. g4 { White pokes at the hovering queen. White cannot play 48. Rxc6 because 48... Ne3+ 49. Rxe3 Qd5+ 50. Ne4 Qxc6 is hopeless for white. } 48... Qg5 49. Kg3 Qc1 { White still cannot touch the pawn on c6. 50. Rxc6? b3! 51. Rxb3 Qf4+ 52. Kg2 Qa4 picks off lots of material. } 50. Nh3 Qc4 { 50... Qxc5 is OK also. } 51. g5 $2 { White is desperate. He plays for a swindle. } 51... h5 { The only move. } 52. Re8 h4+ 53. Kg2 b3 54. Rb8 Qe2+ 55. Nf2 Ne3+ { White resigned here. There would follow: } 56. Rxe3 Qxe3 57. Rb7 Qxg5+ 58. Kf3 Qxc5 59. Ne4 Qc2 60. Rxa7 b2 61. Rb7 b1=Q 62. Nc5 Qf1+ 63. Kg4 Qcf5+ 64. Kxh4 Q1h3# 0-1
