The Colle System, also known as the Colle–Koltanowski System, is a chess opening system for White that has been a part of the chess landscape since the 1920s.
Named after the Belgian master Edgard Colle and further developed by George Koltanowski, this system has been both praised and criticized by various chess experts.
Here we look at the Colle System, its move order, theory, variations, history, and its suitability for different levels of players.
Move Order of the Colle System
The Colle System is characterized by a specific set of moves not limited to a single move order.
White’s center pawns are developed to d4 and e3.
The king’s knight is developed to f3.
The king’s bishop is developed to d3.
The queen bishop’s pawn (c-pawn) is developed to c3.
Common continuations include development of the queen’s knight to d2 (Nbd2) and kingside castling (0-0).
A major theme of the Colle System is the ambition to play a well-timed e4, where the square is defended by the bishop on d3, the knight on d2, and possibly the rook on e1 after castling and shifting the rook to that square.
Below is an example of a Colle System position:
Theory, Strategy, and Purpose of the Colle System
The Colle System is not a fixed line of play but rather a system where the moves may be permuted at the player’s discretion.
The ambition to play a well-timed e4 is a central theme.
The system is often described as “slow and solid,” with a plan to play e4 in the near future.
Despite being regarded as totally innocuous by some, it offers solid development and good chances of not losing against a stronger player.
Variations of the Colle System
One notable variation of the Colle System is the Colle–Zukertort System.

This variation is characterized by developing the dark-squared bishop on b2.
The typical plan includes moves like 1.d4 d5 2.Nf3 e6 3.e3 Nf6 4.Bd3 c5 5.b3 Nc6 6.0-0 Bd6 7.Bb2 0-0.
Despite the apparently innocuous development, White will eventually play for a kingside attack.
Another line that has been tested is 3…Bf5, sometimes called the “Anti-Colle.”
