1. Nf3 d5 2. d4 e6 3. c4 c5 4. cxd5 exd5 5. Nc3 Nc6 6. g3 Nf6 7. Bg2 Be7 8. O-O O-O 9. Bg5 c4 10. Ne5 Be6 11. e3! According to Khalifman in Opening Repertoire according to Kramnik part 5 this is White's best chance for an advantage. The alternatives 11.Nxc6 and 11.f4 lead to unclear play. 11... Nd7 12. Nxc6 bxc6 13. Bxe7 Qxe7 14. b3 Nb6 15. bxc4 After 15. Qc2 Khalifman recommends 15... Qd7!? for Black. Keep this move in mind! It was played by Grischuk in 2001 against Maghami. One of the ideas is to exchange light squared bishops with Bh3. 15... Nxc4 16. Qa4!? Still following Khalifman. This active move confronts Black with his weakness on c6. According to Khalifman, White has the advantage in this position. He continues with 16.. . Nb6?! 17.Qa6! followed by a4 with a pleasant position. But I had another idea. 16... Qd7! Strictly speaking, this idea wasn't entirely new. Not only had Grischuk played it already in a slightly different position (after 15.Qc2), but I myself had had the idea on the board in a club game against Rob Witt. There, the moves 16...Rab8 17.Rfb1 were interposed first, but I decided it was more useful to put the queen on the diagonal c8-h3 immediately, and protect c6 already. 17. Rfb1 Rab8 Black is going to play Rb6 and Rfb8, and there's not much that White can do about that. 18. Rb3 Witt played 18. Rb4 which transposes to the game. White has to take on b6 sooner or later. 18... Rb6 19. Rab1 Rfb8 An important position for the evaluation of Black's idea. White now has to find a clear plan to break Black's fortress. In the game, he doesn't succeed, but I wouldn't be surprised if White doesn't have any advantage after Qd7 anymore. 20. Qa6 20. Rxb6 axb6 (20... Rxb6!?) 21. Rc1 Witt-Moll, Amsterdam 2006 21... h5!? and I don't think Black is worse. 20... h5! After this move, Black doesn't have problems anymore. White now switches to massive exchanges, resulting in a drawish ending. 21. Rxb6 Rybka suggests 21. Na4!? Rxa6 22. Rxb8+ Kh7 23. Nc5 but after 23... Qd6 24. Nxa6 Qa3 Black's position is OK. 21... Rxb6 21... axb6!? 22. Rxb6 axb6 23. e4 23. Bf1 b5 is again fine for Black. 23... dxe4 24. Bxe4 24. Nxe4 was slightly sharper, but after 24... Bd5! (24... Qxd4 25. Qa8+ Kh7 26. Ng5+ Kg6 27. Nxe6) 25. Qa8+ Kh7 26. Ng5+ Kg6 27. Bxd5 Qxd5 28. Nh3 Kh7 Black has nothing to fear. 24... g6 and a draw was agreed. After 25.d5 massive exchanges follow again, after which a dead position arises. 1/2-1/2
