White retreats, but the pin is not a problem. |

11... Be6

Completing the development of the minor pieces, and blocking the e-file. |
|

|
|
12. Ba4
|
This is the third time the bishop has moved. White is falling behing in the element of time. |
|

|
|
12... Rc8
|
Black wants to preserve is pawn structure in case white chooses to capture. |
|

13. Bxc6
|
The fourth move of a piece that is exchanged for one that has moved only once. Now, black's spatial advantage is combined with an edge in development or time. |

13... Rxc6

Restoring material equality. |
|
| |
|
|
14. d4
|
This restablishes spatial equality in the center, but the moves d3 and d4 waste a tempo. Notice the white pieces on a1 and b1 have not moved even once. |
|
| |
|
|
14... c4
|
Black converts the spatial advantage in the center to the wing. |
|

15. b3
|
White wants to challenge the queenside expansion before it gets too far along. |

Or 15. ...b5. Black is not worried about a capture on c4, because the rook would recapture. Then white would be saddled with a backward's pawn on c3. |

Black would love to play with 2 bishops versus 2 knights. |

It is important for white to eliminate one of the bishops. |

Black continues to expand on the queenside. |

18. Bxg7

This helps white by exchanging the bishops, but it took white alot of time to accomplish. The pieces on a1 and b1 still have not been developed. |

Reestablishing material equality. |

Occupying the center with tempo due to the attack on the rook on c6. |

Black is going to play b4-b5 at some point, so is happy to position the rook along the b-file. |

20 moves into the game, the knight finally moves. |

Continuing the theme of queenside expansion. |
