Advice on how to play against the Kings Indian Defense?

Everytime I face the Kings Indian Defense, I totally don't know what to do. I usually lose, I can't seem to figure out how to play vs. it. I don't castle long and attack, but is that better?

I really need some help, I am facing it nearly every game now.

1.e4 move order or 1.Nf3 move order?  

Usually Nf3/Nf6 order

What about the early ...Bg4 line?  It's played quite frequently at the top level.  Here's a very recent example from Wesley So, albeit against a much weaker opponent (the ideas are still there though, and many other top players play this line as black, I'm sure you can find lots of games in a database):

There are many other ideas too, such as exchanging the LSB for white's knight, adopting a semi-slav pawn structure of c6/d5/e6, and other developing schemes as well.  I'm not sure what your repertoire is though...maybe 1...d5 doesn't work for you?  Anyways, this is just an idea.  

Thanks, but I think i mis-spoke. I usually face it as white, not black. Is that the kings indian DEFENSE?

A few years ago, there were a number of books with advice for White:

Yeah...thats the KID, an entirely different opening, disregard everything I said lol.  There are dozens of ways to play against it...just pick one you like and learn it.  

Bump

I have never faced the KID (I'm a 1.e4 player), but I think a Saemisch is decent:

White can continue in a Yugoslav Attack-like fashion with Be3, Qd2, O-O-O and so on.

A Sämisch player at a good level needs to prepare a response to ...a6 +...c6 + ...b5 lines; the Panno (5...a6 6...Nc6 7...Rb8 intending ...b5); 5.f3 O-O 6.Be3 c5! (which is meant to equalise for Black); and the traditional mainlines with ...e5. It's quite theory-rich and you need to be ready for a whole host of plans from Black.

The 5.h3 (or 5.Nf3 O-O 6.h3) lines are doing quite well for White at the moment, and quite a few Black players won't know exactly how to play against them (myself included!). Otherwise, there's the Smyslov line (1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.Nf3 O-O 5.Bg5) or the Fianchetto, both of which lead to quieter waters.

Against openings like KingsIndian and modern white, at least for the first few moves, can play anything they like, depending on the taste, experience and ability of the OP, which I don't know or frankly care about. 

Here's a super aggressive way to counter the KID; The Four Pawns Attack

If annoying your opponent is your main objective (i.e. playing exchange variations against the French), then the Fianchetto variation is quite solid - it deprives Black from the Mar Del Plata style attack (which is very frustrating).

The Smyslov (Bg5) lines may catch lower rated opponents off guard but a strong opponent will know how to play against it.

Otherwise Saemisch and 4-pawns attack are quite solid although you would need to understand the resulting positions.

Against the Saemisch as Black I don't personally play the ...a6, c6, b5 lines because White can set up a f3-e4-f4-c5 pawn structure which is a hard one to crack.

thanks so much to you guys. It was much needed.

Spassky. Your answer lies there.
