You don't know what you are talking about. Name a well-known chess teacher who teaches what you are asserting regarding the London System. That is, you can play the same moves in the same sequence regardless of the moves your opponent plays. You can't.
I never said the same sequence. I said the same set of moves.
You changed your sentence so you realised I might be right.
I give up. There's no point in debating with the clueless.
