11. Bd4 |
White doesn't mind trading the dark square bishops, because that takes much of the sting out of black's setup. 11. 0-0 is another good alternative. | ||||||||
| | |||||||||
|
11... Qa5 |
Black wants to clear the back rank and connect his rooks. One of the interesting things about the geometry of the chessboard, is that moving the queen to the edge, also activates it in the center. Do you see how from a5, the queen attacks the key central squares d5 and e5, as well as the less crucial but still important squares c5 and f5? | ||||||||
| | |||||||||
|
12. O-O |
White has maintained his advantage in space, but is now lagging a bit in development. Black must try to take advantage of this soon or risk drifting into passivity. | ||||||||
| | |||||||||
|
12... Rfc8 |
Which rook belongs on the c-file? Black is hoping to open more lines on the queenside, so leaves the rook on a8 where it is for now, and activates the other rook. | ||||||||
| | |||||||||
|
13. b3 |
Securing the c-pawn, but it also represents an additional weakening of the dark squares in whites center and queenside. White is counting on the bishop on d4 to compensate. | ||||||||
| | |||||||||
|
13... a6 |
Black would love to be able to play b7-b5 at some point, and a6 increases his chances of doing so. | ||||||||
| | |||||||||
|
14. f4 |
14. Nd5 is also promising. White is increasing his spatial advantage. | ||||||||
| | |||||||||
|
14... Rab8 |
Again, with an eye towards an eventual b7-b5. | ||||||||
| | |||||||||
|
15. Qd3 |
A move with multiple purposes. It provides additional suppoprt to the knight on c3, discourages b7-b5 and assists f4-f5. The f4-f5 push is the usual plan in these types of positions. | ||||||||
| | |||||||||
|
15... Bd7 |
Probably not best. Black is still thinking about b7-b5. 15. ...Ne8 was more prudent, and 15. ...b7-b5 more thematic. In the latter line black sacrifices a pawn for piece activity, hoping to win it back under more favorable circumstances. | ||||||||
| | |||||||||
|
16. e5 |
A good aggressive continuation taking advantage of white's edge in space. | ||||||||
| | |||||||||
|
16... Bf5 |
Redeploying the bishop to a more active post with tempo. | ||||||||
| | |||||||||
|
17. Qe3 |
Getting out of harms way and keeping the pressure on. | ||||||||
| | |||||||||
|
17... dxe5 |
This capture is virtually forced. | ||||||||
| | |||||||||
|
18. Qxe5 |
This was came as a surprise and was a big relief. 18. fxe5 keeps the pressure on and even 18. Bxe5 was to be preferred. When you have an edge in space, generally speaking, you should avoid exchanges. When you are cramped seek them out. | ||||||||
| | |||||||||
|
18... Qxe5 |
Black is very happy to get the queens off of the board. | ||||||||
| | |||||||||
|
19. Bxe5 |
White may have underestimated the small combination at black's disposal in this position. | ||||||||
| | |||||||||
|
19... Ng4 |
Finally exploiting the weakened dark squares. | ||||||||
| | |||||||||
|
20. Bxg7 |
20. Bxb8 Bxc3 is fairly level. Notice that white can't play 21. Rac1 because of 21. ...Bd4 and 22. ...Rxb8. - | ||||||||
| | |||||||||
|
20... Kxg7 |
After the exchanges any spatially advantage for white is much less important. White's advantage in the endgame now shifts to a 3 on 2 pawn majority on the queenside. Both sides will want to create a passed pawn, but only white's will be an outside passed pawn, which means the pawn will be on the other side of the board from the kings, and therefore more difficult to stop. | ||||||||
