The Closed Game: 1.d4 d5 2.Nf3... 3.e3 arises after 1.d4 d5 2.Nf3 Nf6 3.e3 and falls under ECO code D04. This enters the Colle System, a systematic opening built around the central idea of preparing the e4 pawn break. Two distinct setups exist within the system. The traditional Colle, played in the style of its namesake Edgard Colle, features the developing sequence Bd3, c3, and Nbd2. The Colle-Zukertort system takes a different approach: since the dark-squared bishop tends to be passive behind the e3-pawn, White plays b3 instead of c3 to fianchetto it, with the b3-pawn also supporting a later c2-c4 advance. Because White's early moves follow a predictable pattern in both setups, Black enjoys considerable freedom in choosing their own formation. With 14.2 million Lichess games across all rating levels, it is a well-established opening choice.
