1. e2e4  1... c7c5  2. g1f3  2... g7g6 This Sicilian Variation is not very popular at the highest level. After 3.d4 the game can go to what we know as the \"Maroczy Bind\" or else to lines of the \"Accelerated Dragon.\" But the game quickly takes an original road. 3. c2c3  3... d7d5  4. e4e5  4... b8c6  5. f1b5 An interesting move and far less played than 5.d4. 5... c8g4  6. e1g1  6... d8b6  7. c3c4 [%c_effect c4;square;c4;type;Mistake;persistent;true] A very optimistic move that puts White in serious trouble. 7... e8c8  8. b5c6  8... b6c6  9. h2h3  9... g4e6 Black already has an almost winning advantage here, although with kings on opposite sides there is always hope of complicating the game. That's what Kosteniuk starts trying now. 10. f3g5 [%c_effect g5;square;g5;type;Interesting;persistent;true] Sacrificing a pawn. 10... d5c4  11. g5e6  11... c6e6  12. f1e1  12... g8h6  13. b2b3 [%c_effect b3;square;b3;type;GreatFind;persistent;true] White does everything to open files on the queenside. 13... h6f5  14. c1a3  14... b7b6  15. b3b4  15... c5b4  16. a3b4  16... e6c6 [%c_effect c6;square;c6;type;Mistake;persistent;true] An imprecise move that gives chances to White. The queen is less useful than it looks on this diagonal. The priority is to develop the bishop on f8 and to remove the king from the c-file. 17. b1a3 Now 18.Nxc4 is threatened, and the rook is coming to c1, positioning itself in an x-ray with the black queen. 17... d8d4  18. a3c2  18... d4d3  19. a1c1  19... f8h6  20. d1g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] The queen is very well positioned here, keeping an eye on the c4-pawn. 20... c8b7 [%c_effect b7;square;b7;type;Inaccuracy;persistent;true] 21. e1e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] 21... b6b5  22. c1b1 Bringing the rook into the attack and also setting up Bc3, freeing up the b4-square for the knight. 22... h8c8  23. b4c3 Black only has one move now. The trend of the game is not good, and the evaluation of the position has changed from \"comfortable advantage\" to \"very dangerous.\" In these cases, it's very difficult to be cold-blooded enough to find the best moves. 23... a7a5 [%c_effect a5;square;a5;type;Mistake;persistent;true] 24. c2a3 [%c_effect a3;square;a3;type;GreatFind;persistent;true] Black's position completely collapses now. All pawns on the queenside pawns will be captured. 24... b7a6  25. b1b5  25... d3c3  26. d2c3  26... h6c1  27. e4c4  27... c6c4  28. b5a5  28... a6a5  29. a3c4  29... a5b5  30. a2a4  30... b5c5  31. c4a5  31... c8b8  32. g4c4  32... c5b6  33. c4b5  33... b6c7
