1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... c7c5  4. d4d5  4... e6d5  5. c4d5  5... d7d6  6. e2e4  6... g7g6  7. f2f4  7... f8g7  8. f1b5 [%cal df1b5][%c_arrow f1b5;keyPressed;none;from;f1;opacity;0.8;to;b5;persistent;false] Historically this line has always been considered one of the most dangerous against the Benoni. 8... f6d7 It is firmly established in opening theory that this is the best way to cover the check. 9. a2a4  9... b8a6 Now and in the next moves Black can castle, which may lead to a transposition of moves. But Rapport has other plans. 10. g1f3  10... a6b4 This variant became famous due to Kasparov's analysis of his win against Nunn, published in the book The Test of Time, one of the best chess books ever written. 11. e1g1  11... a7a6 Kasparov attaches a question mark to this move and suggests 11...0-0. 12. b5d7 A direct continuation of the attack and a paradoxical move, as White normally doesn't want to exchange his light-squared bishop for a knight, further facilitating Black's development. The idea is to play f4-f5 next, when the absence of the knight in the defense can be felt. It's very difficult to say without deep analysis which move is better, whether this or bringing the bishop to c4 or e2. 12... c8d7  13. f4f5  13... e8g8 [%c_effect g8;square;g8;type;GreatFind;persistent;true] 14. c1g5  14... f7f6  15. g5f4  15... g6f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] Another move that gets a question mark in Kasparov's original analysis. Apparently Rapport has his own opinions on classical games. 16. d1d2 [%c_effect d2;square;d2;type;Interesting;persistent;true] An interesting novelty. White plays slowly: the idea is to move the rook to e1 and then play Bh6, when the attack develops easily. Black needs to be fast. 16... f8e8 [%c_effect e8;square;e8;type;GreatFind;persistent;true] 17. a1e1  17... c5c4 [%c_effect c4;square;c4;type;GreatFind;persistent;true] A typical move, securing the d3-square for the knight. 18. e4f5  18... e8e1  19. f3e1  19... d7f5  20. f4d6 [%c_effect d6;square;d6;type;GreatFind;persistent;true] 20... d8d6  21. f1f5  21... a8e8 White has problems with the d3-square and the dark squares. It's important to prevent the bishop on g7 from becoming active in the following moves. 22. g2g3  22... d6d7 [%c_effect d7;square;d7;type;Interesting;persistent;true] 23. f5f1 [%c_effect f1;square;f1;type;Inaccuracy;persistent;true] 23... f6f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] Now the g7-bishop comes to life again. 24. d5d6 [%c_effect d6;square;d6;type;GreatFind;persistent;true] A good move to create counterplay. 24... b7b5 Both 24...Re6 and 24...Qe6 are interesting alternatives. 25. a4b5  25... a6b5  26. c3e2 [%c_effect e2;square;e2;type;Mistake;persistent;true] Attacking the b4-knight is the right idea, but this square is wrong. 26... e8e6 [%c_effect e6;square;e6;type;GreatFind;persistent;true] A sensational move. 27. f1f5  27... e6e2  28. d2e2  28... d7f5  29. e2e8  29... g7f8 [%c_effect f8;square;f8;type;Mistake;persistent;true] A difficult choice, but objectively this move is wrong. 30. d6d7  30... b4c6  31. d7d8q  31... c6d8  32. e8d8  32... b5b4  33. d8d1 [%c_effect d1;square;d1;type;Mistake;persistent;true] The losing move. 33... f8c5 There's a forced mating attack now. 34. g1g2  34... f5f2  35. g2h3  35... f2f1  36. h3g4
