9...Nxd5
Also possible is 9...exd5 10. a4 Rb8?! (10...b4 is correct, with counterplay) 11. axb5 Rxb5 12. b3 Be6 13. Bb2 Qd7 14. Ne5 Nxe5 15. Bxe5 Ng4 16. Bc3 Bf6 17. Bxf6 Nxf6 18. Ra6 Rc8 19. Qa1 Rc7 20. Nf3 Rb6 21. Ra5, with a small edge to White in Movsesian, S - Karjakin, S, Antalya 2013.
10. Ne4
Or 10. c3 Bb7 11. Qe2 a5, with equality in Genrech, L- Sretenskij, N, Dos Hermanas 2003.
Or 10. a4 b4 11. Nc4 (11. Nb3 Bb7 12. Nfd2 Rc8 13. Qg4 Nd4 14. Nxd4 cxd4 15. Nc4 Nf6 16. Qe2 Bxg2 17. Kxg2 b3 18. cxb3 Rb8= D'Amore, C - Nielsen, P, Gothenburg 2005) 11...Bb7 12. h4 Rc8 (12...h6 13.

Or 10. c4 bxc4 11. dxc4 Nb6 (11...Ndb4!? 12. Ne5 Bb7 13. a3 Nxe5 14. Bxb7 Nbd3=) 12. b3 a5 13. Bb2 a4 14. Ne5 Nxe5 15. Bxe5 Ra7 16. Ne4 Qxd1 17. Rexd1 Bb7, with a slight advantage to White in Markus ,R - Kravtsiv, M, Germany 2014.
10...Bb7








   
11. c3
A novelty. After (11. Bd2 Qc7 12. c4 (12. Nc3 Nxc3 13. bxc3=) 12...bxc4 13. dxc4 Ndb4, Grossmann, S - Lindenberg, G, Greifswald 2003 (13...Nf6!? 14. Bf4 Qb6=) 14. Bf4 Qb6 15. Qe2, Black has sufficient counterplay.
11...a6
Or 11...Qb6 12. a4 b4 13. Nfd2 Rad8 14. Nc4 Qc7 15. Qh5 e5, with counterplay.
12. a4 b4
Black could try 12...h6.
13. Bg5 f6
Interesting is 13...h6!? 14. Nxc5! hxg5 15. Nxb7 Qc7 16. c4 Nb6 17. d4 Qxb7 18. d5 Na5 19. d6 Bf6 20. Nxg5, with compensation.
14. Bd2 e5 15. Rc1!
White ends development and plans to seize the c-file.









   
15...Rf7?!
A dubious move. Correct is 15...Rc8 16. d4 cxd4 17. cxd4 Nxd4 18. Nxd4 exd4 19. Rxc8 Qxc8 20. Qb3 Kh8 21. Nxf6 Rxf6 22. Bxd5 Qf5 23. Qf3 Qxf3 24. Bxf3 Bxf3 25. Rxe7 h6, with equality.
16. d4!
Peter sacrifices a pawn.
16...bxc3?!
16...exd4 is better, 17. cxd4 cxd4 18. Bh3 Bc8 19. Bxc8 Rxc8 20. Qe2, and White has only a small advantage.
17. bxc3 cxd4 18. cxd4 Nxd4
White obtains a clear advantage after 18...exd4 19. Qb3 Rb8 20. Bh3 Ba8 21. Qc4 Nb6 22. Qxa6 Nb4 23. Qb5, and Black must defend.
19. Nxd4 exd4 20. Qb3!
A strong multi-purpose move: White's queen pressures on the a2-g8 diagonal and attacks the b7-bishop.
20...Rb8
After 20...Qd7 21. Rc4 f5 22. Rb1 Ne3 23. fxe3 Bxe4 24. Rxd4 White is better.
21. Rb1 Qd7








   
22. Rec1!
A quiet but powerful move. White seizes the open c-file to play Nc5.
22...Qe6?!
A mistake. However, in the case of 22...h6 23. Qa2 Kh8 24. Nc5 Bxc5 25. Rxc5 Nc3 26. Bxc3 dxc3 27. Rxc3 Kh7 28. Rcb3 Bxg2 29. Rxb8 Bh3 30. Rc1 White has a clear advantage.
23. Nc5 Bxc5 24. Rxc5 Rd8 25. Ba5 Rd6 26. Qc4!
And White wins. Excellent play by Peter Svidler!









   
26...Nc3
If 26...h5 then 27. Rxb7 Rxb7 28. Bxd5, winning.
27. Rxb7 Qe1+ 28. Bf1 Ne2+ 29. Qxe2
29. Kg2 is also good, 29...Nf4+ 30. gxf4 Qe4+ (30...Qe6 31. f5) 31. f3 Qg6+ 32. Rg5 fxg5 33. Rb8+ Rd8 34. Rxd8#, checkmate.
Black resigned. 1-0
