  3. Line against the Colle system, thoughts?

lichess.org/study/E2qZcJi7

@SirDillyMoves and I have come up with yet another anti-d4 system line, this one against the Colle. From our analysis so far it looks perfectly good for black. Thoughts on it? Thanks!

poor defence against colle. you do not play e3 but nd2 +1 for white if he plays natural.

I don't think you know what a "gambit" is.
