Learn How to Win Material: Trapped Piece
This middlegame puzzle shows how a pinned piece can become a tactical liability. White’s queen and bishop activity create pressure, but Black’s counterplay is based on a rook invasion that targets loose pieces and forces a decision. The key idea is to use active rook placement to overload the defender and win material by exploiting a trapped piece. In classical chess, these tactics often appear when one side’s back rank and queen-side coordination are slightly off.
