Learn How to Win Material: Hanging Piece Tactic
This middlegame puzzle is a classic example of a hanging piece tactic: one loose enemy piece sits on a vulnerable square, and the position is ripe for a forcing tactical refutation. White can exploit the alignment of the pieces, the open file, and the pin on the queenside to win material decisively. The key idea is not a flashy attack, but accurate calculation that converts a tactical oversight into a large material gain.
