King's Indian Defense
For those interested in using the KID:
The KID (king's indian defense) is one of the most dynamic openings for black in response to 1. d4. It starts with the odd 1... Nf6, at first allowing white to grab control of the center, before later only to seize it back. In the traditional King's Indian games, the purpose of black is to close off the center, dividing the board into two halves: the queenside and the kingside, naturally ( a divorce!). White then proceeds to attack from the queenside, while Black undertakes the task of attacking the kingside. These games tend to lead to exciting games, better for Black in my opinion, but if White's plays correctly he or she should be able to rip the queenside wide open.
In the following game, it shows the consequences of white beginning the attack too late, allowing Black to gain tempo on the kingside. It is from a game I played in USCF tournament.
