Learn How to Trap a Piece: Winning Material
This middlegame puzzle is a classic trapped piece example where one side’s active queen and rook create a tactical net around the enemy king and bishop. The key idea is not a flashy mate, but a forcing sequence that wins material by exploiting a pinned and overloaded defender. In practical classical chess, these positions often arise when king safety is compromised and a piece has no safe squares. Recognizing that a trapped piece can be captured after forcing exchanges is the main lesson.
