Colle System
Setup moves: 1.d4 d5 2.Nf3 Nf6 3.e3 e6 4.Bd3 c5 5.c3
The Colle System is a classical, easy-to-learn repertoire choice. White builds a solid pawn chain on dark squares and aims for the thematic e4 break, often followed by a kingside assault with Ne5, f4, and Qf3.
- Low-theory approach ideal for club players.
- Leads to powerful king-side attacks when timed with e4 and f4.
- Flexible move orders can transpose to Colle-Zukertort setups with b3 and Bb2.
