first off, why do you want them to not play it? if you know it as black, shouldnt you be better off as white vs. the KID than, say, the nimzo?
but to avoid it youd have to play the Tromp or something like that... and that sideline would be against all Indian defenses so it would be hard to isolate just the KID..
I play indian kings defence alot, so I would like to know what's the best way to either stop someone from going into the kings indian defence, or make the kings indian defence a bad decision for black?
