14... Bxf3 
 | 
Now that the pin is broken, Black figures that his game will be easier if he trades pieces. | 
   
    | 
|   | 
| 
 | 
15. Qxf3 
 | 
Black must defend f7 or lose the pawn and allow White to invade, so he castles. | 
   
    | 
|   | 
| 
 | 
15... O-O 
 | 
This protects the King and the pawn, and allows the Rook flexibility to join the fray as is pleases. Black's main idea now is to attack the doubled pawns on the c-file and then dominate the c-file. |

White puts his Rook on a good square. It attacks Black's pawn on b7 and therefore develops with tempo. It also allows the Rook some flexibility to defend the pawn on c4. | 
   
    |

16... b6 
 | 
Unfortunately, Black has to block his Queen's access to a5, which makes her a very depressed piece there on the back rank. |

This move feels a little pointless to me, except that it clears the way for Rf4 and then Rh4, which are a major part of White's attacking idea.  | 
   
    |

17... Rc8 
 | 
Black's attack begins. | 
   
    | 
|   | 
| 
 | 
18. Rb4 
 | 
White defends his pawn valiantly. | 
   
    | 
|   | 
| 
 | 
18... a5 
 | 
Black wants to chase the Rook to a4, where his Queen can attack it with tempo. | 
   
    | 
|   | 
| 
 |

White decides to leave the pawn. He also gets access to a very nice looking rank. So he hasn't given up the pawn without compensation.  | 
   
    |

19... Qc7 
 | 
Black decides to add some more pressure, since he has time. | 
   
    |

20. Rf4 
 | 
Now a trap has appeared. If 20. ...Qxc4 21. Rxb6 e5! 22. dxe5 Qc5 ! | 
   
    | 
|   | 
| 
 | 
20... Qxc4 21. Rh5 
 | 
White sees the trap and clears that diagonal. Black must now be a little careful. White has a powerful attack brewing, so before Black can continue his attack he must be sure that he is safe. | 
   
    | 
|   | 
| 
 | 
21... Kh8 
 | 
I think that 21. ...Qxc3 was better because it basically ruins White's whole attack. | 
   
    | 
|   | 
| 
 | 
22. Rh6 Qxc3 23. Qh4 
 | 
This couldn't have happened with the Rook still on h5 (thus Black should not have moved the King, but rather he should have taken the pawn first). Luckily, Black has a tactical idea that wins (and even if it didn't, it would allow him to defend). | 
   
    | 
|   | 
| 
 | 
23... Qxd4+ 24. Kf1 
 | 
If 24. Kh1 Rc1 . | 
   
    | 
|   | 
| 
 | 
24... Rc1+ 
 | 
Black is very lucky that this tactic arrived on the scene, because without it he would have had to defend against the attack on the h-file. | 
   
    | 
|   | 
|

White's lack of defense is becoming readily apparent. That's his only move. | 
   
    | 
|   | 
| 
 | 
25... Qb2+ 
 | 
Now if 26. Kd3 Rc3  27. Kd4 Qb4  28. Kd5 Rc5# or 26. Ke3 Rc3  27. Kd4 Qb4  28. Kd5 Rc5# | 
   
    | 
|   | 
| 
 | 
26. Kf3 
 | 
Again, this is White's only move (his other two options lose by force). |
