21... Ke8
The king must move, and that gives white time to capture the knight on b3.

 
22. Bxb3
After the smoke clears white is a piece ahead, has an extra pawn, and has a rook on the seventh, while black's rooks remain disconnected on their original squares. White's advantage is overwhelming.

 
22... g6
It is time to just pick your poison, but 22. ...g5 was better.

 
23. Rxc7
Adding another pawn to the material plus.

 
23... h5
There is nothing constructive for black to do.

 
24. Bf7+
I would've probably played 24. Rd1, with the threat of doubling rooks on the 7th. 24. Rd1 Rd8 25. Rxd8 Kxd8 26. Rxa7 is clearly winning for white, but the game continuation is more than adequate.

 
24... Kd8 25. Rc6
White is letting black coordinate his rooks, which I would've tried to prevent, but it hardly matters, since white is up so much material.

 
25... Ke7
Allowing another pawn to fall, but connecting his roooks.

 
26. Bxg6 Rad8
Finally activating one of the rooks, but it is too little too late.

 
27. Rc7+ Rd7
The only chance was 27. ...Kf6 with the idea of getting his d-rook to the seventh. With every piece exchange, white's material advantage looms larger.

 
28. Rxd7+ Kxd7 29. Rd1+
Even at this late stage, white is developing with tempo.

 
29... Kc6 30. Rd5
Merciless! White merely has to create a passed pawn, and escort it to the queening square. Black will be helpless to stop it.

 
30... h4 31. Rxe5 Rg8 32. Bf5 a5 33. Be6
Not merely attacking the rook, but gaining control of the g-pawn's queening square.

 
33... Rg6 34. Bd5+ Kc7
Notice how 34. ...Kd6 allows 35. Re6 Rxe6 36. Bxe6 Kxe6 37. f4, where white has simplified into an easily won k p ending. Simplification is an important endgame strategy.

 
35. Rh5 Rg4 36. h3 Rf4 37. g3 hxg3 38. fxg3
Now, white has three passed pawns, of which two (g and h-pawns) are connected. Connected passsed pawns are a real force in the ending, because they can help protect one another as they advance.

 
38... Rf6 39. g4
The march begins. Passed pawns are very strong in endings, because it forces piece to try and blockade them. Tieing a piece down to the defense of a square limits its mobility, which in turn limits its power.

 
39... Kd6 40. g5
40. e5 is another winning move.

 
40... Rf8
40. ...Rg6 would've only prolonged the struggle.

 
41. g6
Notice that the bishop covers the g-pawn's queening square. Black cannot stop the advance of the pawn.

 
41... Ke7 42. g7
1-0 The key to this game was white's aggressiveness after he got a lead in development. He continued to make threats while developing, which forced black to make further concessions. White then cashed in on his advantage in time by winning material. His lead in development was so great that he was able to continue to attack and win even more material. By the time black finally got untangled the material deficit was so great that resistance was futile.
