Bf3 {Up until now it seems that Kramnik has been able to outplay his opponent. He has the better bishops and when he has access to c5 he will attack a6.} Nf6 19. Qe2 Ne8 20. g4 $5 {Gaining space on the kingside, but perhaps a little unnecessary.} Ned6 21. Bg2 Qc8 22. Nbc5 Re8 23. Bg3 Qd8 24. Rcd1 e6 25. f3 {White's plan is to push e4 at some point, but he doesn't seem particularly well placed to do so. After all, d4 will be very weak.} Qe7 26. Kh1 Bh6 27. Nf4 Nb7 28. Ncd3 Nd8 29. e4 $2 {Kramnik felt prepared force this advance, but he is far from. d4 is not the only weakness, b4 is also going to be difficult to defend. If anything the break seems to simply help Black.} Nc6 30. exd5 Nxb4 {The awkward moment for White. His structure is horrible and he has to somehow justify it.} 31. dxe6 (31. Nxb4 Qxb4 32. dxe6 Bxf4 33. Bxf4 Rxe6 $19 {Black's pieces are swarming, has the better structure and much better coordination.}) 31... Nxd3 32. Rxd3 (32. Nxd3 Qxe6 33. Qxe6 fxe6 {looks pretty bad for White also. The structure is very good for Black, Ne3 is a threat, a5 is also hanging...}) 32... fxe6 33. Qe1 Qd8 34. h4 Rf7 (34... Bxf4 35. Bxf4 Bd5 {is also unpleasant for Kramnik.}) 35. g5 Bg7 36. Bh3 Rxf4 $1 {A nice exchange sacrifice. This takes advantage of the speceific placement of the pieces now to maximize the activity of Black's minor pieces.} 37. Bxf4 e5 38. Bg3 e4 $1 39. Rd1 (39. fxe4 Bxe4+ {is completely winning.}) 39... Bd5 {Black's down the exchange. But it's obvious that White has nothing to play for, his pieces don't coordinate at all and his king is weak.} 40. Be5 exf3 41. Qf2 Qxa5 {two pawns and the position has not improved for White.} 42. Bg4 Rf8 43. Rd3 Qb4 44. Bg3 h5 $1 45. gxh6 Bxh6 46. Kh2 Nd2 $19 47. Ra1 Ne4 48. Qc2 Nxg3 49. Rxa6 (49. Kxg3 Qd6+ 50.
