1. d2d4  1... g8f6  2. c2c4  2... c7c6  3. b1c3  3... d7d5  4. e2e3  4... e7e6  5. g1f3  5... f8e7 A rare move. Van Foreest had prepared something... 6. f1d3  6... d5c4  7. d3c4  7... b7b5 It was Bent Larsen who figured out that this pawn can be advanced without the necessity of preparing it with a7-a6. 8. c4d3  8... b5b4 Apparently Black wants to prevent the e3-e4 advance. 9. c3e4 The most common reply. 9... b8d7  10. e4f6  10... d7f6  11. e3e4 And this is played anyway $1 Always a dangerous move against the Slav. 11... c8b7  12. e1g1  12... e8g8  13. e4e5 Once the black knight is removed from the f6-spot, all kinds of tactics start to lurk. 13... f6d7 Van Foreest does not blink and keeps blitzing. 14. d3e4  14... d8b6 It was only here that Black started to think, and he spent almost twenty-five minutes on the clock for his last move. Alas, without the queen in Her residency, Black's kingdom is in a horrible state. 15. c1g5 A normal positional idea $2 15... e7g5 Blitzed out in a flash, and probably Kaidanov could not believe his eyes. After a thorough check, he executed a famous tactical idea. 16. e4h7 [%c_effect h7;square;h7;type;Brilliant;persistent;true] The Greek gift sacrifice at the very top level $1 16... g8h7  17. f3g5  17... h7g6 The only move, but as we shall see, Van Foreest has missed an important detail. 18. d1g4  18... f7f5  19. g4g3  19... b6d4 This was the move that Black was hoping for. Believe it or not, this is a novelty. Which, however, changes nothing. 20. g5e4 [%c_effect e4;square;e4;type;Brilliant;persistent;true] Black sank back into deep thought, but there was no way back for him anymore. 20... g6h7 At least trying to slightly worsen the position of the white queen. 21. g3h4  21... h7g6  22. h4g5  22... g6f7  23. a1d1 Now Black can take the pawn. 23... d4e5  24. d1d7  24... f7g8  25. d7b7 But White won a piece nevertheless and quickly finished the job. 25... e5b2  26. e4c5  26... f8f7  27. b7f7  27... g8f7  28. f1d1  28... b2e5  29. d1d7  29... f7g8  30. h2h4  30... a8e8
