How to play against King's Indian Defense??

I've also always had trouble against the KID, and I've also tried all of the lines OP said. I currently play the Smyslov System, but I played the Saemisch for a long time, and might go back to it in the near future. Basically, f3+Be3+Qd2+0-0-0 and go from there. Often some Kb1+Nc1 maneuver. Sometimes I even just leave the pawn on d4 and don't advance it again. Although I used to go for Bh6 like Water_Flame suggested, I've found its usually better to just leave black with their bad bishop.

Here's a pretty cool game I found: lichess.org/3hDAA6hL#49

Bore them to death with the exchange variation!

I play Kings Indian all of my life.

@FunnyAnimatorJimTV #1 #7 With white against Kings Indian I played Mainline Classical and Makogonov (5.h3). For some reasons i scored bad with Makogonov, so meanwhile i always play classical. I know this in and out with both colors, so i feel comfortable with it from both sides. Check out games by Korchnoi with white in this line.

@TatsumakiRonyk #2 nonsense. :-p

@achja #5 Bf4 and Bg5 setups yes, everybody plays it. On Lichess this seem to be the mainlines against everything.
I feel comfortable against it.
* Bf4 can lose a tempo against e7-e5 or it has no effect when black plays c5 and lets e7 and d6 where they are.
* Bg5 wants to provoke weaknesses, h6, g5 but if black plays it sensible it feels more like a waste of time to me. Also black often plays c5 and the bishop g5 never really fits well against c5 setups.

@ the dudes suggesting exchange variation. Every hardcore Kings Indian loves dxe5. An even endgame with some winning chances due to the weak square d4, cool, lets play this.

@ the dudes suggesting Sämisch, Black seems to equalize in the 6...e5 line. However he doesnt do so by attacking on the Kingside but by neutralizing white on the queenside. so this may be an option if you dont like Kingside attacks. You must also have something against 6...c5 - and probably there is nothing :)

You can try Samisch variation, and castle queenside. Most of the time you will be attacking the opponent's king. (the plan is very aggressive; swap off his dark-squared bishop, and push Harry the h-pawn up the board)

King's Indian Defence is difficult for black. Kasparov gave up on it and shifted to the Queen's Gambit Accepted and the Slav Defence. Kasparov commented that black struggles in several lines. He especially referred to the classical variation, where Kramnik scored well with b4, but he mentioned also other lines. Nakamura did not dare play his usual King's Indian Defence against Carlsen in a must win as black situation and got a draw. Comment from Carlsen: if he wanted a bad position he could have played King's Indian Defence. Houdini won as white 2 King's Indian Defences against Kodomo in the ongoing TCEC Superfinal 2017. Bronstein said King's Indian Defence poses a bigger risk to black than King's Gambit to white.

@tpr You're saying play the Bayonett Attack? The main problem I'm having with the KID us that white's attack seems too slow compared to black's kingside. It appears the only method which avoids the kingside attack is the Smyslov System, where the center remains open. However then you have to worry a bit about the g7 bishop...

Here is an example of superb white play.

Kasparov said black strugles after b4 but also after Nd2 or Ne1.
Kasparov said he did not consider the King's Indian Defence refuted, but it took more time than he had available to work out reasonable defences for black.
