1. e2e4  1... c7c6  2. g1f3  2... d7d5  3. d2d3 I must say that this is a rather curious system to employ against the Caro-Kann Defense. Followers of this solid variation are usually happy exchanging queens with a safe position. 3... d8c7 Kosteniuk is an attacking player, so she doesn't want the boring ending after 3...dxe4. 4. g2g3  4... e7e5  5. f1g2  5... g8f6  6. e1g1  6... d5e4  7. d3e4  7... f8e7  8. b1d2  8... c8e6 I am a follower of the \"when in doubt, castle\" principle, which will once again prove its worth, considering that this was the most accurate choice here and in the following moves. 9. b2b3 The bishop is developed in the excellent a1-h8 diagonal. 9... b8d7  10. c1b2  10... h7h6 This move is understandable: Black wants to avoid Nf3-g5. However, the knight move was not yet such a worrying threat. 11. d1e2 Preparing Nd2-c4. 11... b7b5  12. f3e1 [%c_effect e1;square;e1;type;GreatFind;persistent;true] An excellent move. The knight goes to d3 and the f-pawn is ready to go. 12... e8g8  13. e1d3  13... c6c5 Preparing counterplay with …c5-c4. 14. c2c4 [%c_effect c4;square;c4;type;GreatFind;persistent;true] 14... b5c4  15. d2c4  15... e6c4  16. b3c4  16... e7d6 White has a clear advantage with the pair of bishops and the plan of attacking on the kingside. 17. f2f4  17... f8e8  18. a1e1  18... f6h7  19. b2c3  19... h7f8  20. f4f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] A good practical decision. 20... f8h7  21. d3f2  21... d7b8  22. f2g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] 22... b8c6  23. f5f6 [%c_effect f6;square;f6;type;GreatFind;persistent;true][%c_highlight g7;keyPressed;none;opacity;0.8;square;g7;persistent;false,h6;keyPressed;none;opacity;0.8;square;h6;persistent;false,g8;keyPressed;none;opacity;0.8;square;g8;persistent;false] 23... h6h5  24. g4e3  24... g7g6  25. e3d5 [%c_effect d5;square;d5;type;Inaccuracy;persistent;true] This is not the most incisive. 25... c7d7  26. e1b1 [%c_effect b1;square;b1;type;Inaccuracy;persistent;true] 26... c6d4  27. e2e3  27... a8b8  28. h2h3  28... d6f8 Black should try to attack the queenside with the queen. Kosteniuk probably didn't want to separate the queen from the king and leave it unprotected, but this measure was necessary. 29. g1h2  29... d7d6  30. e3f2  30... b8b1  31. f1b1  31... d6c6  32. h3h4  32... c6d6  33. g2h3  33... e8b8  34. b1f1  34... b8b7 [%c_effect b7;square;b7;type;Mistake;persistent;true] This was the last chance to create counterplay on the queenside. From now on, it's too late. 35. g3g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] Black's king is in severe danger now. 35... h5g4  36. h3g4  36... d6b8
