20. Raxc1 Nxf2 
 | 
notice how black is clearing out the D file with a pesky insistence on controlling the center of the board and gaining tempo through threats of gaining material... | 
   
    | 
|   |

21. Bxf7 Bd3 
 | 
White greedily takes the f7 pawn, without realizing the fierce discovered attack that black could set up with Bd3... |

22. Qxd8 Bc4 
 | 
Black executes the discovered attack, only to find that the white Queen is not able to check her own King. In situations like this you want to remain calm and look for opportunities to counterattack with the strong pieces you have in a threatening position, in this case, for Black that will be his King... |

23. Nf6 Kxf7 
 | 
Black begins his fierce counterattack with his King... |

24. Qe7+ Kxe7

This next series of moves is brilliant!  |

25. Rce1+ Kxf6 
 | 
Notice how the Black King continues to gain material while White slowly withers away, his substantial lead in material down to a mere +5... |

26. Rhf1 c5 
 | 
White pins the f2N, and black cannot do anything about it, and so black advances some of his pawns. Now you will see Black continue to advance his King into the attack, gaining temp in the open file in the center along the way with threats and checks.  |

Black is is position now to defend his N, but has left himself vulnerable to attack from the other rook... |

30. Rxf2+ Kxf2

A fairly even exchange of material. Note that Black is now only down 2 points! The comeback is nearly complete!  |

31. Rxa7 Bd3

Continuing to develop the minor pieces and look for rook outposts... |

This move was the crusher! Black locks down the d3 square with this powerful pawn push, and White is helpless! |

33. a4 bxa4 
 | 
White tries in vain to break up the d3 bishop outpost, but only succeeds in granting black a passed pawn (hint hint, the winning move will come from that passed pawn!)  |

The black pawn is free!  |

35. Rg2+ Kxg2

The Black King is still in a strong position, and continues to rack up material gains! IN fact, Black is now finally ahead in this game!  |

Chasing!  |

Still chasing!  |

The underpromotion to a Knight in this case was warranted, as White has begun to realize in this game that the Black King is much more powerful than anyone could have expected. Clearly it was more valuable to stop the Black King from advancing along the g file, and so the underpromotion to protect the g6 square was essential. Note that promotion to a Queen or Rook or Bishop would not have been able to control that g6 square -- only a knight would do the trick! |
