45. ... d4!?

Although this move is speculative, Kramnik sacrifices a pawn to activate his rook and bishop. Objectively it may be not the best, but for a human player passive defense is intolerable, so that justifies his decision.
46. exd4 Re6+ 47. Kd2 Bd3 48. d5 Rd6 49. Kc1 Bg6 50. Bb4 Rxd5 51. Rxa6 Kd7 52. Rf6 Rb5 53. Bc3 Rf5 54. Rb6 Rxf4
188The active rook is able to eliminate white pawns, achieving a draw now.

29. ... e5 30. dxe5 Nxe5 31. fxe5 Qxe5

Black has only a pawn for a piece, but White's pieces are badly placed, and all of his pawns are vulnerable.
32. Nf1 Bg7 33. a3
( Defending the pawns was not really possible in the long run: 33. Kd2 Re6 34. Nb7 Bh6 35. Nc5 Bxe3+ 36. Nxe3 Qxe3+ 37. Kd1 Re5 -/+ [%eval -32767,0] Black has still more ways to improve his position with Rhe7, Qxg3 and d5-d4. )
33. ... Qxc3+ 34. Qxc3 Bxc3 35. Bd1 Re6 36. Bc2 Bg6
190Both White's rooks and knights are effectively out of the game for many moves to come, so the current material balance is virtually irrelevant here.
37. Nd2 Rxe3 38. Rd1 Bf6 39. Rhh1 d4 40. Rde1 Rhe7 41. Rxe3 Rxe3
In view of inevitable material losses, White resigned. A true positional masterpiece by Kramnik!

45. ... f5 46. gxf5
193
46. ... Rf6!!
Paradoxically, this is the only move that keeps Black alive!
( After 46. ... Ra6 47. e6! the black rook would be cut off from the kingside and Black would lose: 47. ... Ra7 48. f6 +- )
47. Kg3
( 47. e6 Qe4 = )
47. ... Qe4
Now the game ends with a repetition.

36. g5!?

White opens up the game to exploit the power of his two bishops.
36. ... hxg5 37. hxg5 Nxg5 38. Bc6 Rc8 39. Rh1
As compensation for the pawn, White's rooks are also obtaining a lot of potential - on both sides of the board.
39. ... Kg8 40. Raa1 Nce6 41. Rh4
White is threatening to double on the 'h' file, so Black has to create an escape square for his king.
41. ... f6 42. Rg1
195
42. ... Kf7 43. Bd5 Ke8 44. Rh8+ Nf8 45. f4 Ne6 46. Kf3 f5 47. Rg6
196Black's pieces are tied up in too many ways, so White begins to pick up the fruits of his labour.
47. ... Nc5 48. Bxg7 Rf7 49. Bxf8
( 49. Bxf8 Rxf8 50. Rxf8+ Kxf8 51. Rg8+ Ke7 52. Rxc8 +- )
