11. dxc5
|
The pawn capture now because the queen at d8 is blocked. |

|
|
|
11... Nxc5
|
Recapturing and offering a reduction of 2 queens from the board. |

|
|
|
12. Qxd8+
|
Taking it closer to the endgame. |

|
|
|
12... Nxd8
|
The best move. Better than Ke8xd8, and definitely better than Be7xf8 losing the c5 knight. A necessary move, but black devolves a little with 4 pieces on the back rank. |

|
|
|
13. b4
|
The knight has few good squares and must flee the center. |

|
|
|
13... Nd7
|
Another piece lands in the pile. No fault of black on this move, it is just the way the position is playing out. |

|
|
|
14. a3
|
Simply shoring up b4. Nc3-b5 with the intent of Nb5-c7+ was a thought, but black would see it coming and either castle or move the rook. |

|
|
|
14... Ne5
|
Black seeks useful squares for the knight, or at least safe ones. The problem is a discoordination of pieces. Both bishops need open lines - black has in effect 2 bad bishops because of the pawn structures of both players. Some pawn moves could break open some lines, but there is the danger of not having tied rooks that will present itself if not remedied. Another problem for black is underdevelopment of pieces. |

|
|
|
15. f4
|
The knight will be forced to move yet again, costing tempo. |

|
|
|
15... gxf4 16. Bxf4
|
Recapturing and asking the knight to step-off. |

|
|
|
16... Nc4
|
Its a good foothold for the knight, but it is working alone. |

|
|
|
17. Nb5
|
Remember the Nb5-c7+ fork threat - it is still there. |

|
|
|
17... e5 18. Bh2
|
Keeping the north-west line is preferable, so the bishop relocates to a safe position on that line. |

|
|
|
18... Ne6
|
A good move that prevents the fork at c7 and offers d4 or f4 at a later time to the knight. |

|
|
|
19. Bd5
|
With the idea of removing the defender of c7. |

|
|
|
19... Bd7
|
With the idea of attacking the loose knight, but not so good because it only offers the appearance of an equal trade. White can capture and protect in one move. The turning point in the game. |

|
|
|
20. Bxc4 a6
|
To dislodge the knight and limit the danger. |

|
|
|
21. Bxe5
|
Creating a greater threat while gaining material. |

|
|
|
21... O-O
|
Black obtains a better position while ghosting the rook from danger and keeping a counter attack pressed to the knight at b5! |

|
|
|
22. Nd6
|
Pressing the position, prevents Ra8-c8. |
