Here's how Ukrainian GM won in the second round. 

Anton KOVALEV (2636) - Vassily IVANCHUK (2738)
Grunfeld defense

1. Nf3 g6 2. d4 Nf6 3. c4 Bg7 4. Nc3 d5 5. Qb3 dxc4 6. Qxc4 O-O 7. Bf4

 

7...Na6 8. Rd1?! (the major line is 8. e4) 8... Be6! (an unpleasant for white reply, rarely played in practice) 9. Qa4 ( 9. d5? doesn't work because of 9...Nxd5! with the continuations working in black's favor) 9... Nd5 10. Be5 Nb6!? 11. Qc2 Nb4! 12. Qb1 Bxe5 13. Nxe5 (black is better after 13. dxe5 Qc8!? too) 13... c5! 14. dxc5 Qc7! 15. cxb6 (neither 15. Nxg6 hxg6 16. cxb6 axb6 leads to complete equality, with a trap 17.a3? Rxa3) 15... Qxe5

16. bxa7?! (white has to choose between 16. a3 and 16. g3) 16... Qa5! 17. a3 Na2! (avoiding the trap 17... Nd5 18. b4 Qxa3? 19.Nxd5 Bxd5 20. Rd3!) 18. Rd3 Rfc8!

19. e4? (stedier was 19. Qd1!? Nxc3 20. Qd2 Rxa7 21. Rxc3 Rxc3 22. Qxc3 Qxc3+ 23. bxc3 Rxa3 24. Kd2, although the endgame is still tough for white) 19... Nxc3 20. bxc3 Rxc3 21. Qb4 Rc1+! (white has no chance with the passive king's flank)  22. Kd2 Qg5+ 23. Re3 Ra1! (black has a variety of choices to convert the advantage)

24. e5 Rxa7 25. f4 Qg4 26. Rf3 Bd5 27. h3 Qe6 28. Rc3 Ra8 29. Ke3 Re1+ 30. Kf2 Re4! 31. Qc5 Rxf4+ 32. Kg1 Qxe5 33. Bb5 Qe4 34. Rg3 Rf5 35. Qb6 Rxa3 0-1

    Baadur Jobava went on with a rare line in Sicilian against Emil Sutovsky. Earlier it was mostly played by IM Eduardo Limp. Sutovsky sacrificed the pawn after the well examined theory. Although the energetic attack brought White a point, it is probable that Jobava could escape several moves before he resigned.
