Trapped Bishop Puzzle (Rated 1367): Win Material — Trapped Piece

A trapped piece is a tactical problem where an apparently active defender has limited safe squares. In this middlegame, Black must recognize that exchanging on a strategically important square changes the balance of material and leaves White’s active rook vulnerable. The key idea is to calculate forcing exchanges before retreating or defending. When an opponent’s pieces are overloaded, a precise tactical refutation can turn a material disadvantage into a decisive advantage.
