The Colle system setup is a quiet White plan that leaves the c1 bishop behind a pawn on e3 for now and groups the other pieces, with Bd3, Nf3, Nbd2 and c3. The Colle system setup is a quiet White plan that leaves the c1 bishop behind a pawn on e3 for now and groups the other pieces, with Bd3, Nf3, Nbd2 and c3, around one central push, e3-e4. Where the London develops its dark bishop early, the Colle deliberately leaves it on c1 and accepts a slower start in exchange for a very solid center. The payoff comes later, when e4 frees that bishop and opens lines for everything else. That e4 push is the heart of the system. It works best when the [knight](https://georgelichess.com/glossary/knight.md) on d2, the bishop on d3 and often a rook on e1 all support it, so that after an exchange on e4 White recaptures with a piece and gains activity. If White pushes too soon, Black simply exchanges and is comfortable. There are two common versions. With c3, White keeps a compact [pawn chain](https://georgelichess.com/glossary/pawn-chain.md) and waits for e4. With b3 and Bb2, the Colle-Zukertort version, the queen's bishop goes to the long [diagonal](https://georgelichess.com/glossary/diagonal.md) instead and aims at Black's king. [Tactics](https://georgelichess.com/glossary/tactic.md) follow the light-squared bishop. Once e4-e5 drives away a knight on f6, the [sacrifice](https://georgelichess.com/glossary/sacrifice.md) Bxh7+ becomes a real threat, so Black must watch h7 whenever the d3 bishop and the queen can reach it. Typical errors: playing c4 out of habit, which turns the game into a different [opening](https://georgelichess.com/glossary/opening.md), and letting Black strike first with ...e5 while White is still preparing e4. Tip: before playing e4, count attackers and defenders of the e4 square and push only when the count favors you. ## Example position The Colle-Zukertort version: b3 and Bb2 put the queen's bishop on the long diagonal, the other bishop waits on d3, and Nbd2 followed by Ne5 or e4 is White's next step. Position (FEN): `r1bq1rk1/pp3ppp/2nbpn2/2pp4/3P4/1P1BPN2/PBP2PPP/RN1Q1RK1 w - -` Compare it with [London system setup](https://georgelichess.com/glossary/london-system-setup.md). The London system setup is a White plan that brings the dark-squared bishop to f4 before e3 can shut it in, then builds a sturdy triangle of pawns on c3, d4 and e3 that suits nearly any Black reply. Also worth reading is [Stonewall structure](https://georgelichess.com/glossary/stonewall-structure.md). A pawn formation with pawns on c6, d5, e6 and f5 (for Black) or c3, d4, e3 and f4 (for White) that builds a solid wall controlling e5 or e4 but leaves the light-squared bishop passive. Compare it with [System opening](https://georgelichess.com/glossary/system-opening.md). A system opening is a fixed setup that a player uses against almost any reply, such as the London or the King's Indian Attack, trading theoretical depth for familiar plans and a repeatable structure. Whether "Colle system setup" suits your repertoire depends on the games you play.
