1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f3 { This is the Saemisch Variation, a very aggressive setup for white against King's Indian. White wants to play Be3, Qd2, 0-0-0, and try to launch an attack on black's kingside. So, black needs to play this type of opening a bit differently.
I'd suggest having another opening in your back pocket, in case you're playing an opponent who you know plays Saemisch Variation against King's Indian. Maybe you can play Grunfeld or Nimzo-Indian against such opponent, that way you're not as predictable. :) [%csl Bg7][%cal Bc1e3,Bd1d2,Ye1c1,Rh2h5,Rg2g5] } 5... O-O 6. Be3 { Are you ready for this amazing, secret move?? :) } 6... a6 $3 { Brilliant!!!! This move completely stifles white's plans.
Essentially what this a6 move does is it turns this "Saemisch King's Indian" into a "Benko Gambit with an Awkward Setup for White". That's right, we're leaving King's Indian territory! It's quite important to know the types of plans in many different openings. [%csl Ga6] } 7. Qd2 Nbd7 { If you're not familiar with the Benko Gambit, basically black gambits a pawn on the queenside in compensation for a compact pawn structure and clear planning of pressurizing white's queenside by using the a and b files in cooperation with the bishop on g7 and the knights. It's one of very few fundamentally correct gambits.
Because of this queenside pressure, it would be a bit foolish for white to castle queenside! White can't storm the kingside attack he wishes to because black will be able to put too much pressure on the queenside. I put an example sideline game where white castled queenside and lost.

Most likely white will play d5 and not dxc5. dxc5 would be illogical for white to open the center and give up on the idea of a wing attack.

Summary: Against Saemisch King's Indian, you play 6...a6 followed by Nbd7, c5 and b5, turning the King's Indian into a Benko. It's a very good system that simplifies the game for black! The ideas: Sacrifice a pawn with b5, open the a+b files, play Qa5 and pressurize the queenside. Don't be afraid to exchange the queens with Benko! It's sound enough for black to exchange queens. } *
