1. d4 2. Bc4 is not possible.
I play the Queen's Gambit as white, not any of these systems, and sure the London and Colle are very quiet, but I don't get the point of your post. If people want to play unambitiously, so be it. You should try to play dynamically against their passive openings, or better yet, watch GM Shankland's videos on beating passive QP openings and then see if you have these problems.
The main reason I think people play these openings is that people have school, or jobs, or family that they need to attend to, and they don't have time to spend on learning random variations of sharp KID or Grunfeld theory and would rather just play the same sort of thing over and over again. Sure it leads to uneventful games but it's their decision.
Whenever I play against someone who plays d4, then doesn't play c4, it makes me want to shoot myself.
2. nf3
2. bc4 or bf4
2. nc3
All crap. It leads to 20 moves of shuffling pieces around aimlessly until someone makes a tactical blunder or misses a pawn push (usually the other person). Its not a slow positional strangling, its a slow game period. Most of them don't even lead to cool endgames.
Anyone else feel this way?
