Learn How to Win Material: Trapped Piece
This middlegame puzzle is about recognizing when a piece is overloaded and cannot escape. White’s king safety is the key factor: the attacking queen creates a tactical refutation by pressuring multiple targets at once, while the trapped knight has no useful squares. The best practical response is a forcing defensive move that changes the tactical geometry and wins material by removing the attacker’s support. It’s a classic example of using calculation to convert a positional edge into a concrete gain.
