exd5 Puzzle (Rated 1600): Trap Pieces — Gain
A trapped piece can decide a middlegame even when one side appears materially ahead. The key is to recognize when an attacking piece has entered deep into enemy territory while its escape squares are controlled. In this position, Black’s tactical opportunity comes from combining an attack on a valuable rook with pressure against an overloaded queen. The resulting exchange changes the material balance and gives Black a decisive advantage.
