Colle System Kingside Attack in Chess

The Colle System Kingside Attack is a plan where White’s Colle setup (typically pawns on d4/e3 and c3, with the light-squared bishop often on d3) is used to generate pressure against Black’s kingside. A defining feature is the early kingside space and coordination that supports a pawn thrust like f4 or g4, followed by piece swings toward e4/g4/h4. The goal is to create threats on the dark squares around the king while keeping the center stable.
