Learn How to Trap the Queen: Winning Material
This puzzle shows a classic trapped-piece idea in the middlegame: one well-timed bishop move creates a tactical net around the enemy queen and turns a skewer-like threat into a winning combination. White already has the better space and more active pieces, so the key is to use coordination rather than a direct attack on the king. The point is to force the queen into an awkward response and then win material with a lower-value piece.
