Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Be3 c5 8. Rc1 Qa5 9. Qd2 O-O 10. Nf3 Bg4 11. Ng5 (11. d5 {was Kramnik's try against Svidler in 2009. Ng5 is not as common.}) 11... Na6 12. h3 Bd7 13. Bd3 $6 {This move might be too optimistic.} Rac8 14. d5 c4 15. Bb1 Nc5 16. Bd4 { surprisingly this had all been played before in a low rated game between Moussa-Kauffman, 2010.} Bxd4 {A new move, and one that definitely makes sense.} 17. cxd4 (17. Qxd4 Nd3+ $1 {Anyways.} 18. Bxd3 cxd3 19. Qxd3 Bb5 $1 $17 {The inability to castle kills White's coordination, Black is certainly to be prefered.}) 17... c3 $1 {Karjakin must have missed this idea; or he overestimated his chances.} 18. Rxc3 {the only move, or c2+ was lethal.} Nd3+ $1 {This is the point of the combination, the h1 rook is going to hang to a skewer.} 19. Rxd3 Rc1+ 20. Ke2 Qxd2+ 21. Kxd2 Rxh1 22. Rb3 {White has compensation for the lost exchange. He does have one pawn and his central pawn mass is nothing to sniff at, however it is not sufficient.} b5 (22... b6 {was both more natural and more solid.}) 23. Nf3 f6 24. Ne1 a5 $6 {Grischuk advances his queenside pawns, but they are not a trump. They become weaker the more they move forward.} 25. Rc3 Rc8 26. Rc5 b4 27. Bd3 {By this point it has become clear that moving the pawns forward did not help Black at all.} a4 28. Ra5 b3 29. axb3 axb3 30. Ra7 Rd8 31. Rb7 {With the death of b3 it is Black that has to thing about equality, but it will still be within grasp.} Ra8 $5 { Keeping the game complex. This is not a bad move, but with Grischuk's consistent time trouble it was wiser to level the position as soon as possible. } (31... Ba4 32. Ra7 (32. Rb4 Ra8 33. Bc4 Kf8 $11) 32... Bd7 $11) 32. Rxd7 Ra2+ 33. Kc3 Rxe1 34. Kxb3 Rxf2 35. Rxe7 Re3 36. Kc4 Rd2 37. Bb1 Rb2 $2 {This is the start of the end for Grischuk.} (37... Re1 $1 38. d6 Kf8 39. Rb7 Red1 {was still equal.}) 38. d6 $1 {The pawn is very powerful. The rooks are surprisingly useless against it.} Kf8 39. Bd3 Rd2 40. Bf1 Ra3 (40... Re1 41. Kc3 Rdd1 {is unpleasant but had to be played.}) 41. Kb4 Ra1 42. Bc4 Rc1 43. Rf7+ Ke8 44. d7+ Kd8 45. Kc5 $1 {The support of the pawn is too much, while the e4 and d4 pawns keep the rooks away from the action.} Kc7 46. Rxh7 Rcd1 ( 46... Rdc2 47. d8=Q+ Kxd8 48. Kd6 $18) 47. d5 Rc1 48. g4 g5 49. d8=Q+ Kxd8 50. Kd6 Ke8 51. Bb5+ Kf8 52. Ke6 Re1 53. Kxf6 {The pawn count is too high!} Rf2+ 54. Kg6 {a small bit o precision. e4 is now taboo, so Grischuk resigned.} (54. Kg6 Rxe4 55. Rh8+ Ke7 56. Re8+) *
