Learn How to Win the Exchange: Trapped Piece
This middlegame puzzle shows a classic trapped-piece idea in the Philidor Defense: one tactical shot can force a major material win by exploiting king safety and loose back-rank coordination. White’s queen invasion and bishop activity create a direct threat against the rook on h8, while Black’s king remains exposed and the defenders are overloaded. The key lesson is that a seemingly active piece can become tactically frozen when the opponent’s pieces coordinate on the same target.
