Caro Kann Defense Advance Variation Discovered Attack in Chess

In the Caro-Kann Defense, Advance Variation, White usually builds the center with 1.e4 c6 2.d4 d5 3.e5, creating a fixed pawn chain. A discovered attack in this structure happens when a piece moves to open a line for another piece, often revealing pressure on the black king, queen, or a loose central piece. The defining feature is the Advance Variation pawn chain, where the e5 pawn and supporting pieces create tactical lines that can suddenly open with a single move.
