Normally 10. Rd1 is played: 10... Qc8 11. Bg5 (11. Qf5 Nf6 12. Nc3 O-O (12... Nc6 13. Bg5 d5 14. Nh4 Nd4 15. Qxc8+ Rxc8 16. e3 Ne6 17. Bxf6 Bxf6 18. Nf5 Rd8 19. Nxd5 Bxd5 20.

Qxg6+ Kd8 17. a3 It's quite nice to sacrifice and then continue with such a small move! 17... b5 18. e4 Nb6 19. Nc3 d6 Radjabov thought 19... Ne6 to be the best move, because after 20. Nxb5 Qc6 Black seems fine. But Leko thougth that after 19... Ne6 20. Nd5 is stronger 20... Nxd5 (20... Nf8!? (GM Rogers) 21. Qg4 (21. Qg7 Rh7 followed by taking on d5) ) 21. exd5 Nf8 22. Qd3 Both players didn't like 19... Nc4 20. Qg7 Rf8 21. Bh3 for Black. 20. Bf4 20. Rxd6+ Bxd6 21. Qxf6+ Kd7 22. Qf7+ Be7 23. Bf4 doesn't work because of 23... Qf8 20... Qe6 21. Bxd6 Bxd6 22. Qg7! A strong intermediate move which was missed by Leko. After the immediate 22. e5 then 22... Kc8! is strong, e.g. 23. Bxb7+ (23. Rxd6 Qxe5 24. Rxf6 Bxg2 25. Kxg2 Qh5) 23... Kxb7 24. exd6 Ncd5 22... Re8 23. e5 Qxe5 24. Bxb7 Ne6 25. Qg4 Nd4 26. Bxa8 Nxa8 27. Re1 27. a4!? was an alternative. 27... Qxe1+ 28. Rxe1 Rxe1+ 29. Kg2 Nc7 30. Ne4 Ne8 31. Qg6 Be7 32. Nc3 Re5 33. h4 a5 34. Qd3 Nd6 35.

Nxb5 41. axb5 a4 42. Qxf5 Rxh6 43. Qd5+ Rd6 44. Qa8+ Kd7 45. Qxa4 But even stronger is 39. Qh8! b4 40. Na4 Bf6 41. Qh7 Rc6 42. Qa7 which looks quite good for White. 1/2-1/2
