Learn How to Win a Pin: Decisive Material Gain
This middlegame puzzle is built around a powerful pin on the queen and king line. White’s active bishop creates a tactical bind that forces the opponent’s queen into a vulnerable square, where it becomes overloaded and unable to defend the rest of the position. The key idea is not a flashy attack on the king, but a clean winning combination that uses alignment, pressure, and a hanging piece to convert a small edge into a decisive material gain.
