Queen's Pawn Game: Colle System

1.d4 d5 2.Nf3 Nf6 3.e3

What Is The Colle System?

3.e3 shuts in the c1 bishop, a price White pays on purpose. It frees Bd3, c3, Nbd2 and 0-0, a setup with one goal. Every piece is placed so that the e3-e4 break opens the centre exactly when White's forces already point at Black's king. After the break, the d3 bishop and a knight landing on e5 create mating threats, Bxh7+ among them.

Black's reply decides the game you get. 3...e6 is the main line and the version White hopes for: the c8 bishop sits behind its pawns. 3...Bf5, the Anti-Colle, develops that bishop first and takes the force out of e4. 3...g6, the Gruenfeld Formation, blocks the d3 diagonal and meets e4 with a bishop on g7. Skip the e4 break and the setup gives you nothing.

How Do You Play Against The Queen's Pawn Game: Colle System?

You are Black and the replies scatter: 25% play ...e6, 17% ...Nc6 and 17% ...Bg4. The Colle is a system rather than an opening, so White will play e3, Bd3, Nbd2, c3 and then e4 almost regardless of what you do.

The one move that makes the Colle awkward is ...Bf5 or ...Bg4, because it develops the bishop before ...e6 shuts it in. That single decision is what separates a comfortable game from a passive one. After the bishop is out, ...e6 and ...c5 give you a full share of the centre. White scores 50% to 46% over 2,752 games, an ordinary edge that comes from familiarity rather than from the moves.
