1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be2 e6 7. 0-0 Be7 8. f4 0-0 9. Kh1 Qc7 10. a4 Nc6 11. Be3 Re8 12. Bd3 Bd7 13. Qe1 Nxd4!? Quite a novelty — but hardly sounder than 13. ... Nb4 14. a5 Nxd3 15. cxd3 Bc6 16. Qg3 Rac8 17. f5 e5 18. Nf3 d5 19. Bh6 (Smirin – Summermatter, 6th International Open, Geneva 1992) and now 19. ... Bf8!∞ seems to be tenable.
14. Bxd4 Bc6. 14. ... e5 also deserved consideration, since after 15. fxe5 dxe5 16. Qg3 Bd8 Black somehow holds everything together.
15. Qg3 Bd8? That doesn’t seem a good idea, at least not now.


16. e5! dxe5 17. Bxe5? White ought to take with the Pawn, powerfully keeping the upper hand: 17. fxe5! Nh5 18. Qh3 g6 19. Ne4± with a big edge.
17. ... Qe7 18. f5 exf5? This must be the losing move. Instead, after 18. ... Nh5! 19. Qg4 Qh4 everything was okay for Black.
19. Rxf5 Qe6 20. Raf1+− Kf8 21. b3 b5 22. axb5 axb5 23. Nxb5 Bd5 24. Bxf6 gxf6 25. Nd4 Qb6 26. Rxd5 Bc7 27. Qh4 Be5 28. Nf5 Kg8 29. Qg4+ 1–0.
