how to crush the KING'S INDIAN DEFENCE?

Fischer did not dare to play his King's Indian Defense against Botvinnik, or in Candidates' matches against Taimanov and Petrosian, or his 1972 World Championship match against Spassky.
Kasparov played the King's Indian Defense in World Championship matches against Karpov,
but Karpov played a slow positional system with g3 instead of the Bayonet Attack.

Not so surprising. The line was scarcely known until the 90s.

Yes, it was believed that white had to meet 9...Nh5 with 10 g3 to prevent 10...Nf4.
Here are two 2019 correspondence games white lost in the opening.

You can't crush it. The best you can do is shove an anal bead up your @$$ to crush it. Otherwise, just pick a solid line and build experience.

you dumbo

1.This is not a King's Indian,

2.After 6.e5?! Nh5 white is already overextended.

I love the KID with black and KIA with white.
