The King's Indian works fine against the London.
I use that, in fact ( Nf6-Bg7-d6 ), and I'm quite well. But it’s just a KID setup against a London System; what comes out of it is not a real King's Indian Defense game.
Can you confirm it ? I understand very little about openings, I’m just a classification enthusisast.
Only 1.E4 or 1.d4 should be allowed then no need for random chess and opening theory be cut down. Change my mind.
