Learn How to Win Material: Trapped Piece
This middlegame puzzle is about recognizing when a piece is overloaded by its own duties and can be won through a forcing sequence. The key idea is clearance: remove a defender or blocker so a tactical route opens along a file or rank. In positions like this, active rooks on the seventh rank often create threats, but they can also become targets if the opponent’s back line is vulnerable. Always check whether a seemingly active piece is actually trapped by coordination problems.
