22... Kc7

Avoids the knight fork on f6, which would drop the g4-Bishop. |

Threatening Rxb7 Kd8 (forced) Rb8 winning the g8-Rook. |

|
|
|
24... b6 25. a5
|
Same threat if Black takes on a6. |

|
|
|
25... b5 26. c4
|
Same threat again if Black takes on c4. |

|
|
|
26... a6 27. cxb5 cxb5 28. f4
|
Now shifting the action to the King-side, the f-pawn is a passed pawn, so it makes sense to advance it down the board. |

Rooks go behind passed pawns. |

33...Bxf1 34. fxd7 is good for White.
33...Re6 34. f7 Rf8 35. Rc8! is also good for White. |

This was probably unnecessary, but I just wanted to prevent any counterplay by Black. Except for the passed b-pawn, Black did not have any threats. |

The main alternative was 38. Rxb5 hxg3 39. hxg3 Rxg3 , with a similar material position. |

|

38... Kd5 39. Rxb5+ Kxd4 40. e6

Black will not be able to stop both pawns. |

|
|
|
40... hxg3 41. hxg3 Re8 42. Rb6 Kc5 43. Kf3 Ra8 44. e7
|
If 44...Rxa5, White wins easily: 45. e8=Q Kxb6 |

|
|
|
44... Re8 45. Rb7 Kc6 46. a6 Ra8 47. Kf4
|
Again threatening e8=Q if Black takes on a6. |

|
|
|
47... Kd6 48. a7 Ke6 49. Rb8
|
At least one pawn will queen now, so Black resigned.
