Learn How to Trap a Piece: Winning Material
This middlegame puzzle is about recognizing when a piece has run out of safe squares and can be forced into a losing sequence. The position is materially imbalanced, but the real lesson is tactical: one side can create a direct threat that exposes a piece to capture and leaves the opponent with no good recapture. In practical classical chess, these moments often decide the game because a seemingly active piece becomes a liability.
