1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. f3 e5 7. Nb3 Be6 The Sharp Naidorf variation of the Sicilian Defense! It's apparent that both players are seeking a victory in today's encounter!
8. Be3 Nbd7 9. g4 Nb6 10. g5 Nh5 11. Qd2 Be7 12. O-O-O Rc8 13. Rg1 O-O 14. Kb1 g6 15. Qf2 Nc4 16. Bxc4 Bxc4 17. Na4! A new and very strong novelty! White's Knight is heading to occupy the b6 square.
17... Be6 The dubious attempt to attack with...
17... b5? 18. Nb6 Rb8 19. Na5! Qc7 20. Naxc4 bxc4 21. Nd5! and White has a clear positional edge.
18. Nb6 Rc7 19. Qd2 Rc6 20. Nd5 Bxd5 21. exd5?! I was very surprised at this move. White voluntarily chooses to obstruct the "d" file .... allowing Black the additional option of violent counterplay with f7-f6! The Knight is too far away on b3 to rejoin the action, and Black has no Pawn on b5 in order for White to take advantage of the typical sicilian hole on c6!
21... Rc8 22. Qd3 Qd7 23. c4 f6! 24. gxf6 Rxf6 Anand starts his counterplay. White has extremely weak pawns (f3 and h3) on the King-side for Black to target.
25. Nd2 Rf7 26. Rc1 Qf5!? A much clearer continuation seems to be...
26... Nf4! 27. Bxf4 Rxf4 28. Ne4 Qh3 29. c5 Rxf3! and the Black pieces have come to life!
27. Rc3 27. Qxf5 This idea deserves attention. White has nothing to worry in the resulting endgames.
27... b5 28. b3 Qh3 29. Rgc1 bxc4 30. Rxc4 Ra8 31. Ra4 Bf8! A very nice move! Vishy is offering his opponent the Pawn on a6, however!, only now does Leko realize that it istaboo!
32. a3 32. Rxa6 Rxa6 33. Qxa6 e4! and Black gets a strong initiative. 34. Qf1 Qxh2 35. Nxe4 Qe5!
32... Nf6 33. Bg5 Qxh2 34. Rh4 Qg2 35. Bxf6 Rxf6 36. Rg4? A tragic mistake in the time pressure. After...
36. Qe3 Qg3 37. Rch1 h5 38. R1h3 Qg2 39. Rh2 and Black has to accept the draw.
36... Qh3 37. Rcg1 Ra7 38. R1g3 Qh6 39. Ne4 Rf4 40. Rxf4?? after...
40. Rg1 Black is much better, but at least Anand still has to work to get the full point.
40... Qh1+! 41. Ka2 exf4 42. Rg4 Bg7 43. b4 a5 44. Kb3 axb4 45. Kxb4 Qe1+ 46. Kb3 Qc1 0-1
