Sooner or later, every 1.d4 player you meet online turns out to be a London player, same bishop, same triangle, same plan. Most opponents respond with a shrug and drift into a passive middlegame, which is exactly what the London is hoping for.
This repertoire responds with a targeted plan instead: hit c5 early, develop pressure against the d4 pawn and the b2 square behind it, and challenge the London bishop with ...Bd6 at the right moment. None of it is sharp, and all of it is annoying for White, which is the correct energy against a system opening.
