I think the Exchange variation is a serious try against the KID below 2000, especially if you study it for a while and really understand what both sides are trying to achieve. It gives a big psychological advantage, as black players hate it and are likely to think you're only trying to avoid complications to achieve a boring draw.
What to play against the King's Indian Defense?

An interesting anti- Indian (KID, Grunfeld, Benoni) system with little theory to learn:
This has lately become fashionable even at top level chess, albeit mainly at fast time controls. A Grunfeld without a knight at c3 isn't effective, while a reversed KIA/French is no plain sailing either, as white's extra tempo is really useful. Most logical is 5...c5, when white has a choice between a reversed Tarrasch a tempo up with 6.Nc3 cd4 7.ed4 d5 (about equal, but it may appeal to many if the like Tarrasch-like formations) and 6.d5, which is an odd Benoni with a pawn on e3 and the bishop shut in, but still Black's road to equality is not easy.
That was actually very informative,heck i might even give it a shot,infact i know some grunfeld players who would be very unpleased about not bieng able to play the "normal" grunfeld(when the Knight is on c3) against me :).
Incidentally, this is what Colle-ites have been playing against the "Sneaky Grunfeld" for aeons, lots of times with b4, trying to open up lines against c5, where they try to prove the fianchettoed bishop is misplaced for this particular defensive task.

As a d4 player, I play against the Kid the most on this site. I play 10 min games, so I use multiple variations against it. The 4 pawns atack is the most fun. Be well, play well!

This gambit leads to very sharp play and good chances for white.
Only in Hope Chess, that is.
In reality white is already in trouble after 9...Ne4, which should come as no surprise: Black is ahead in development, and white has self- compromised his only trump: the big center.

It caused Kasparov to quit the King's Indian Defence.

you can also go for the caveman checkmate, if you assume your opponent is an idiot (which is sometimes the case, to be totally honest):

If you don't want to face the KID, or any of the indian defenses, play a King pawn opening.
No black can still force a kings indian with g6

No, that’ll end up a modern or a Pirc, where White is usually doing very well by move 5 or so.

No if your saying white is doing fine and the positions are very similar and when you play the kings indian your position sucks as much as the pirc / mordern
