Queen's Pawn Game Discovered Attack in Chess

In the Queen’s Pawn Game Discovered Attack, a piece on a line (often a bishop or rook) is unblocked so that it suddenly attacks a target—while the move also reveals an attack from behind. A defining feature is that the “unblocking” move happens in the Queen’s Pawn Game structure (typically after developing pieces around d4/c4/e3 and the central pawns), creating a discovered line against a king, queen, or major piece.
