12... Bxf5
|
Forced. |

|
|
|
13. Rxf5
|
13. exf5 was also good, perhaps better. |

|
|
|
13... cxd5 14. exd5
|
The pawns on d6, f6 and g5 really limit the bishop on f8. Its counterpart on c1 is free to roam. This is a big advantage for white. Notice also that only the black h-pawn is on a white square. White's pieces are free to settle on white squares in black's terrotory without having to worry about pawns driving them away. |

|
|
|
14... Qe7 15. Nc3
|
White wants to complete his development, because the structural flaws in black's game are not going away anytime soon. |

|
|
|
15... Nh6 16. Rf1
|
White doesn't want to allow f6-f5 followed by Bf8-g7. |

|
|
|
16... Kd8
|
This was not absolutely necessary, because the threat of Re1 is always answered by Ne5. |

|
|
|
17. Nb5
|
The white squares on the queenside are equally weak, so black will find no shelter there. |

|
|
|
17... Nc5
|
The knight belongs on e5. |

|
|
|
18. Re1
|
Taking advantage of the lapse to take over the e-file. |

|
|
|
18... Qf7 19. Be3
|
The bishop is heading for d4. |

|
|
|
19... Nxd3
|
This loses material and is positionally flawed as well. The knight on c5 was a better piece than the bishop on d3. |

|
|
|
20. Bxb6+
|
An in-between move that wins a pawn. |

|
|
|
20... Kd7 21. Qxd3
|
White is now up material as well as still enjoying a lead in development and a spatial advantage. |

|
|
|
21... a4
|
This allows black to play b2-b4 and eventually c4-c5. 21. ...f5 was to be prefered. |

|
|
|
22. b4
|
The b-pawn will support the c-pawn's advance. |

|
|
|
22... Qg6
|
Black offers the queen trade, but why open the h-file for black? It would just help him untangle his kingside pieces. |

|
|
|
23. Qe3
|
White doesn't mind trading down into an ending, however. The extra pawn, which is soon to become passed, will be decisive. |

|
|
|
23... Re8 24. Qxe8+ Qxe8 25. Rxe8 Kxe8
|
The reduction in material has not eased black's defensive task. The c-pawn is going to cruise to its queening square. |

|
|
|
26. c5
|
Creating a passed pawn on the c-file no matter what black does. |

|
|
|
26... dxc5 27. bxc5
|
The c-pawn's advance can only be stopped by additional loss of material. |
