34. Kh2 c6
With this move the White Queen is blocked from e8, the Black rook is free, and d5 is protected. Now it should be apparent that the four connected black pawns on the queenside are the major force in this game.

 
35. Qxa7
White reduces the enemy pawn force by one. Still, he is trading time for this pawn.

 
35... Kc7
The King continues to hold b7 while also holding b6. The king will need to accompany the pawns up the board and this better positions him.

 
36. Qa4
The a7 pawn capture cost White two tempi, since the Black king wants to move up the board, anyway.

 
36... Ra1
This forces the exchange of queens.

 
37. Qb4 Qxb4 38. Rxb4
The pawns are looking more and more formidable. Two connected passed pawns on the sixth rank are stronger than a rook, and a knight can only stop two connected passed pawns by occupying the square directly in front of the more backward when they are in echelon. That is probably impossible when the White king is far afield, and the pawns are supported by the Black king.

 
38... c5
Here come the pawns!

 
39. Rg4
White now intends to capture the black kingside pawns, and try to distract Black and to queen a white kingside pawn.

 
39... Kc6
The Black King stays with his pawns.

 
40. Nb3
The Knight moves to interfere with the pawns. Perhaps not a good move. The knight has no scope, where it is or where it was. Better may be to advance f4, because after Rxg7 the white f-pawn will be passed.

40... Ra3
There is no place for the knight to move, except back to the square he just left. He will 'sacrifice' himself for one pawn plus the disconnection of the remaining two black pawns.

 
41. Nxc5
This move is forced. Nd2 loses quickly with: 41. ... c4, 42. f4 c3, 43. Nf3 g6, 44. Nd4 Kc5, 45. Ne6 Kb6, 46. Nd4 Ra2.

41... Kxc5
We are now in an endgame. Black's plan is obvious: March the passed pawns up the board. He must use his king, because the rook is ill suited to protect both disconnected pawns. If White begins toward the queenside with his King, the Black rook will need to restrain him. When White's rook attacks a passed black pawn, either King or rook must be in position to protect. Black expects the game to be decided on the queenside, and will not use tempi to protect his kingside pawns. But what is White's plan? He seems to have only one possibility for a draw: to capture one or more kingside pawns, getting a passed pawn on the kingside, and race for a White Queen. However, Black has tempo; his queenside pawns are already passed and one is already on the fourth rank. So, if White chooses this path, he must quickly produce a passed pawn. Which one? Obviously, the f-pawn, because it will become a passed pawn in just one move. White cannot squander tempi, he must leave the h7 pawn rather than waste a move capturing. Having more pawns than black will not win because the deciding factor will be tempo, not material. White's hope must be that he can get his distant king in front of the advancing Black pawns. It may not be possible, since it will require a 'juggling' act by his rook. The rook must restrain the Black queenside pawns without helping Black get his King up the board!

The White rook gets the black g-pawn.The f-pawn is now passed. With White, I would try to queen the f-pawn, time is important: The rook can only hold the Black pawns for a short time and the king is far from the action.

 
42... b5
The Black pawns keep rolling up the board.

 
43. Rxh7
This may be a costly loss of tempo. White should ignore this pawn and play f4 while the Black rook is no threat. Time is important.

Another step forward.

 
44. h4
White cannot stop the Black pawns, he hopes to slow them down and threaten to queen his own pawn.

 
44... b3
Closer to the queening square.

 
45. h5
Had White left and not captured the Black h-pawn, his f-pawn would now be on f6!
