Learn How to Win Material: Trapped Piece
This middlegame puzzle comes from the Philidor Defense and shows how a seemingly active queen can become tactically vulnerable when the position is opened at the right moment. The key idea is not a mating attack, but a decisive material gain based on king safety, loose pieces, and a trapped piece motif. White’s king is still in the center, so Black can use forcing play to punish the exposed queen and convert the initiative into a clear advantage.
