9...Bxd3 10. Qxd3 e6 11. Bd2 Ngf6 12. O-O-O Be7 13. Kb1 Qb6 14. Rhe1 O-O 15. Nf5!








   
15...exf5!
This move is better than 15...Bb4? 16. Nxh6+!, and White had a strong attack in Karjakin, S -Mamedyarov, S, Zug 2013.
16. Rxe7 Qd8 17. Re2 Ne4








   
18. g3
The alternatives are 18.Be1, 18.Bc1 and 18.Bf4. After 18. Be1 Re8 19. g3 Ndf6 (19...Qe7!?) 20. Nh4 Papp, G - Doric, D, Mitropa Cup, Sibenik 2012, Black can play 20...Qd7 with equality. Or 18. Bc1 Re8 19. Rde1 Ndf6 20. Nh4 Qd5 (20...Qd7) 21. Qb3 (21. f3 Ng3 22. Re5 Qd7, 21. Qf3 f4 22. Bxf4 Qxd4) 21...Qxb3 22. axb3 Nxf2 23. Nxf5 Rad8 24. c4 (24.Rxe8+ Rxe8 25. Rxe8+ Nxe8 26. c4 Ng4) 24...Nd3 25. Rxe8+ Nxe8 26. Re7 Nxc1 27. Kxc1 Rb8, and the endgame is drawish. Or 18. Bf4 Ndf6 19. Be5 Ng4 20. Bg3 Re8 21. Rde1 Qa5 22. c3 Ngf6 23. Be5 Ng4, with equality.
18...Ndf6 19. Nh4
White also could try 19. Ne5.








   
19...Qd7!?
A novelty. In the game Kasimdzhanov, R - Ruck, R, Schwetzingen 2013, Black played 19...Re8.
20. Qf3
Or 20. Bf4 Nxh5 21. Nxf5 Qxf5 22. Rxe4 Nxf4 23. gxf4 Rad8, with equality.
20...Qxd4 21. Nxf5 Qe5 22. Bc1 Rfe8 23. Rde1








   
23...Re6
Also interesting is 23...Qd5!? 24. Ka1 Re6 25. g4 Rae8.
24. g4 Rae8
Black equalizes, threatens ...Nc3+, bxc3, ...Qb5+.
25. Ka1
Or 25. Re3=.
25...Qd5 26. Qa3 Nxg4
Or 26...Qc5 27. Qxc5 Nxc5 28. Rxe6 fxe6 29. Ne3 Nce4.
27. Nxg7 Kxg7 28. f3 Nef6 29. Rxe6 Rxe6 30. Rxe6 Qxe6 31. fxg4 Qxg4 32. Qxa7 Qxh5

The endgame is drawish.
33...Qh1 34. Kb1 h5 35. Qc7 h4 36. Qf4 Ne4 37. a4 h3 38. a5 Qe1
Also possible is 38...h2 39. a6 c5 40. a7 Nc3+ 41. Ka1 Ne2 42. Qg4+ Kf6 43. Qh4+ Ke6 44. Qc4+, with perpetual check.

Or 39. c4 Nd2+ 40. Kc2 Qg1 41. Bxd2 h2 42. Bc3+ Kg6 43. Qf6+ Kh5 44. Qf5+ Kh6, with perpetual check.
39...Nd2+ 40. Ka2 Qxc1 41. Qg5+ Kh7








   
42. Qh5+
