Dark Square Control

Submitted by Phobetor on Sat, 08/30/2008 at 2:09pm.

In some variations of the Sicilian, the weak light squares are a common theme. For example in the Sveshnikov Variation (1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5), black plays e7-e5 early on, leaving big holes on d5 and f5. In other variations, the dark squares around the black king are weak. This usually happens when black plays e7-e6 early on, and the dark squares especially become weak when black gives up the dark-squared bishop early on, like in the Sicilian Pin Variation (1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 Bb4).

Below is a game I played in July, where the weak dark squares were very important. Black fianchettoed his dark-squared bishop, but he also left a big hole on d6. After I developed, I took advantage of these big holes by making threats and severely restricting his pieces' movement. When he contested the d6-square with his dark-squared bishop, I saw that he couldn't afford to give up his bishop anyway, even if it cost me the exchange. He took up the challenge, grabbed the exchange, but not much later had to pay the price. There were too many holes around his king, and his pieces still couldn't be activated. On move 30 he resigned in view of forced mate on the next move.

Below is the game with annotations and analysis. Enjoy!

Looking back at it now, I saw it was not so clear why 24... Re8 or 25... Nxh4 are bad. After some thinking, I remembered why it was wrong, but since it was not trivial, I added some variations in those lines to the move list.

@ Crux: The board we played the game on just had a weird diagonal! For some reason, the squares h8, g7, ..., d5, c4 were on one line! Tongue out

Ok, I'll fix it, just for you!

Awesome game, although your annotation to move 20 confused me..."Finding a better place for the knight. If black takes on d6, the c4-h8 diagonal will be very weak, and the white knight is ready to jump to f6 with dangerous threats."

Thanks erik, lapin, madpawn :) Unfortunately this is not an average game and this is one of the few games from my best games collection ;) If only I could play such games every day...

@ Kingfisher: After 26... Nxf4 27. Qxh6 Nh5 white just plays 28. gxh5. I don't see how Nh5 is any good for black...

I think Nimzowitch would have loved the way the dark squares were colonised. I especially like the Petrosian idea of exchanging the rook for a minor piece  (20. Ne4) in order to continue the dark square squeeze. A very instructive game for those who wish to use this important strategy in their game. Thanks

How does 26... Nxf4 lose? Nxf4 Qxh6 Nh5 holds for black

@ ADK: Thanks :) But although the finish required some calculation, the game was actually won around move 20, when I got full control of the dark squares around his king. The combinations and tactics just flow from a superior position.

@ colle-pirc: I highly doubt Kasparov ever played that. This link supports my statement that it's really bad and barely ever played in good games, and this link shows the games of the match you mention, and I don't see any accelerated dragon games. Oh yes, if black played d7-d6 instead of Nc6, then g6 is fine, but not in the game above. And for what it's worth, Fritz 11 rates 5... g6 6. Nxc6 bxc6 as +1.00 for white.
