Another King's Indian
The game you are about to see is a King's Indian where White ended up taking the fight to the Kingside. I don't prefer to play King's Indians like this, but Black's thematic ...a5 stabilized the Queenside situation, and eventually led to a position that held chances for both.
As background, I recommend that you play over my game from the US Amateur Team chp in 2009. You can find the game here: http://blog.chess.com/Jpatrick/cooking-a-kings-indian or in the Chess365 database. If you play over that game, you will get a good idea of how White's game can develop on the queenside.
Okay. Here is the game. If you read and understand the annotations, you will improve your feel for handling the King's Indian Defense.
