Learn How to Win a Hanging Piece: Colle System
This chess puzzle comes from the Queen's Pawn Game Colle System and shows how a small tactical oversight can flip a middlegame. White’s attacking piece is overextended near the enemy king, but it is also vulnerable because it lacks support and can be met by a forcing king capture. In classical chess, these positions often hinge on king safety, piece coordination, and whether the opponent’s last move left a hanging piece. The key lesson is that active-looking threats are not always sound if the defender can respond with tempo and material gain.
