11...Nxd4
After 11...Qc7 12. Nc3 Bd6 (12...Be7) 13. h3 (13. g3! is better) 13...O-O 14. Qc2 Rac8 (14...Nxd4!) 15. Rad1 Bh2+ (15...Rfd8) 16. Kh1 Bf4 17. Ne4 (17. Bxf4) 17...Nxe4 18. Qxe4 Bxe3 19. Qxe3 Rfd8, Black had counterplay in Stellwagen, D - Nataf, I, Germany 2005. Or 11...Be7 12. Nc3 O-O 13. h3 (13. Nf3!) 13...Qc7 (13...Nxd4!) 14. Nf3 Rfd8 15. Qb3 Rdc8 16. Rad1 Be8 17. Bb6 Na5 18. Bxc7 (18. Bxa5! Qxa5 19. Qxb7 Bb4 20. Re5 Bc5 21. Qb3, with a small edge to White) 18...Nxb3 19. Bd6 Bxd6 20. Rxd6 Na5, with counterplay in Zvjaginsev, V - Grigoriants, S, Krasnoyarsk 2007.
12. Bxd4 Bc6
Or 12...Rc8 13. Nc3 (13. Nd2) 13...Bc5 (13...Bc6) 14. Be5?! (14. Ne4 Nxe4 15. Rxe4, with a small edge) 14...Bc6 15. a3 Qxd1 (15...O-O) 16. Raxd1 a5 (16.. O-O) 17. h3 (17. Nd!?) 17...Ke7 18. Nb5?! (18. g3) 18...Bxb5 19. cxb5 Rhd8, with equality in Degraeve, J - Sarthou, G, France 2002. After 12...Be7 13. Nc3 O-O 14. Qb3 (14. Qd2) 14...Bc6 15. Rad1 Qc7?! (15...Qa5) 16. Bb6 Qf4 17. Ne2 Qh4 18. Nd4 a5? (18...Ng4 19. Qg3, with a small edge) 19. Nxc6 bxc6, White was better in Looshnikov, N - Yuffa, D, Satka 2012.
13. Nc3 Be7








   
14. a3!
In the game Kinnmark ,O - Paoli, E, Eksjo 1975 Black got counterplay after 14. Qd3 O-O 15. Rad1 Qc7 16. Be5 (16. Qe3!?) 16...Qa5 17. Qg3 Nh5 (17...Rfd8!?) 18. Qe3 (18. Qh3!?) 18...Qc5?! (18...Rfd8) 19. Qh3 (19. Nd5!? exd5 20. Bd4 Qd6 21. Qxe7 Qxe7 22. Rxe7, with a small edge to White) 19...g6 (19...Nf6) 20. g4 (20. a3! a5 21. Nb5 Rfd8 22. Nd4) 20...Nf6 21. Re3 Rad8 22. Rxd8 Rxd8.
14...a5?!
Weakening his queenside. After 14...O-O!? 15. b4 Qd6 White has only a slight edge.
15. Qd3 O-O 16. Rad1 Qc7
Now White obtains a small but lasting advantage.
17. Be5 Qb6 18. Qg3 Rfd8








   
19. Rxd8+!
A good move, because after 19...Qxd8 White can seize the open file with Rd1. In the case of 19. Bc7?! Rxd1 20. Nxd1 (20. Bxb6? Rxe1) 20...Qc5 the game is equal.
19...Qxd8 20. Rd1 Qb6?!
20...Qf8! is better, 21. Bd3 g6, with a small edge to White.
21. Bd4! Qb3
Black quickly loses after 21...Qxb2? 22. Nd5 Qxa3 23. Nxf6+. Magnus finds an excellent plan: to attack on the queenside with b2-b4.
22. Rd3! Qc2








   
23. b4!
White obtains a clear edge.
23...axb4 24. axb4 Nh5 25. Qe5!
Magnus attacks all over the board!
25...Bf6 26. Qxh5 Bxd4 27. Rxd4 Qxc3








   
28. Qa5!!
White sacrifices his queen.
28...Rf8
If 28...Rxa5 then 29.Rd8+ Be8 30.Rxe8 checkmate.
29. Qb6 e5 30. Rd1
Also good is 30. Rd8 g6 31. b5 Be4 32. Rd7 h5 33. Qd6.
30...g6 31. b5 Be4 32. Qf6
Possible are 32. Rd7 and 32. h4.
32...h5 33. h4
33. h3 deserves attention.
33...Bf5 34. Rd5 Qc1 35. Qxe5
White grabs a pawn.
35...Be6 36. Rd4 Ra8 37. Qe2 Kh7 38. Rd1!








   
38...Qc3 39. Qe4! Ra1
39...Rb8 is more stubborn, 40. g3 b6 41. Kh2 Qf6 42. Qe3 Bg4 43. Rd4 Rc8 44. Bg2, though White has great chances to win here too.
40. Rxa1 Qxa1 41. c5! Qc3 42. Qxb7
Winning.
42...Qe1








   
43. b6?!
Stronger is 43. Qe7! Qb1 44. b6 Bc4 45. b7, winning.
43...Bc4 44. Qf3 Qxf1+?
Correct is 44...Bxf1 45. Qxf7+ Kh8 46. Qf6+ Kh7 47. Kh2 Qe8 48. Qf4 Qd7 49. Qf3 Bb5 50. b7 Qc7+ 51. g3 Kg7 52. Qd5 Kh7 53. f4 Bc6 54. b8=Q Qxb8 55. Qxc6, and White has two extra pawns.
45. Kh2 Qb1 46. b7 Qb5








   
47. c6
And White wins: the b7 pawn promotes to a queen.
47...Bd5 48. Qg3
Black resigned. 1-0
