More precise is 12... Qa5!? 13. Ba3 Be7 14. Bxa6 Nxa6 15. Qd3 Nd5 16. Rc1 Nab4 17. Qc4 c2 18. Bxb4! Nxb4 19. Na3 O-O 20. Nxc2 Nd5 21. dxc5 Qxc5 1/2-1/2, draw in Olsen, H - Kasparov, G, simul, Torshavn 2001. Weaker is 15. Ne5?! Rc8 16. Qb3 cxd4 17. Qb7 Rc7 18. Qa8+ Bd8 19. Bd6 Qd5! 20. Qxd5 Nxd5 21.

Nc2 a6 with an edge to Black in Nikolic, P - Bareev, E, Pula 1997 (0-1, 62).
13. Qxe2 c2!?
A novelty. After 13... Nbd7 14. Nxc3 c5 15. Rd1! (unclear is 15. e4 cxd4 16. Nxd4 Rc8 17. Ncb5 Bc5 18. e5 Nd5 19. Nd6+ Bxd6 20. exd6 O-O, Tisdall, J - Petursson, M, Ostersund 1992) 15... cxd4 16. Nxd4 Qc8 17. Ba3! White had an advantage in Nikolic, P - Hansen, L, Wijk aan Zee open 1993 (draw, 36).
14. Qxc2 Nbd7 15. Ba3 Rc8 16. Rc1!
A strong move.
16...Be7 17. Nbd2 O-O 18. Nb3
If 18. e4 then 18...Re8 19. Rab1 Bf8! 20. Rb7 cxd4 21. Qxc8 Qxc8 22. Rxc8 Rxc8 23. Bxf8 Nxf8 with a small edge to Black. Interesting is 18. Rab1!? Rc7 19. e4 Ne8 20. dxc5 Nxc5 21. Nc4 Nd6 22. Nxd6 Qxd6 23. Bb2 Qa6 with equality.
18...c4 19. Nbd2 Nb6 20. a5 c3! 21. Ne4
Probably somewhat better is 21. Bxe7 Qxe7 22. axb6 cxd2 23. Qxd2 (23. Qxc8 d1Q+ 24. Rxd1 Rxc8 25. bxa7 Qb7 26. Rdb1 Qa8 27. Ne5 g5 28. h3 Kg7 29. Ra6 h5) 23... axb6 24. Ne5 Qb7 with approximately equal chances.
21...Nbd5 22. Nxf6+
More precise is 22. Nc5.
Nxf6 23. Qd3 Nd5 24. e4 Bxa3 25. Rxa3 Qd6! 26. Ra4?!
More precise is 26. Rb3 Qf4 27. Qc2 Nf6 28. Rxc3 Rxc3 29. Qxc3 Qxe4 30. Qc7 a6.
26...Qf4!?
The initiative is in Black's hands. However 26...Nb4! is even stronger.
27. Qc2 Nf6

   
28. d5?!
Better is 28. Re1 Rc7 29. Raa1 (29. Rb4?! Rfc8 30. Re3? Nxe4! 31. Rxe4 Qxe4 32. Qxe4 c2) 29... Rb8 with a small edge to Black.
28...exd5 29. exd5 Qd6 30. Rd4 Rc5 31. Qd3 Rfc8 32. g3 h6
Better is 32...g6.
33. a6
Better is 33.Nh4.
44...c2?!
Zeitnot. Correct is 33... Nxd5 34. Ne1 Qe6 35. Nc2 Re8 with a clear advantage for Black.
34. Ne1 Nd7 35. Kh1?!
Timetrouble. Necessary was 35. Qe2 or 35. Qd2.
35...Ne5 36. Qe4 Qxa6 37. Qxe5? Qf1 mate
White resigned. 0-1
