Colle System
The Colle System is a slow, solid opening system for White. It differs from London System in that the dark-square bishop remains inside the pawn chain, to be developed at a later time. The Colle has a passive reputation since it puts very little pressure on Black in the opening. However, the system plays consistently with ideas that are easy to understand, and is perhaps even more "systematic" than the London.

Strategic guide
Plans and motifs
- White's usual move order is 1.d4, 2.Nf3, and 3.e3.
- White's most common idea is to prepare the pawn break e4 with moves such as Nbd2, Re1, and sometimes Qe2.
- This pawn break unleashes the "potential energy" of White's pieces, opening lines for the dark-square bishop and rook.
- After e4, White can naturally proceed with a kingside attack.
- White's pieces are well-placed for a Greek gift sacrifice.
- Black plays for their own central pawn break, or Black may counterattack on the queenside with the pawn storm ...c5-c4 and ...b5.
