Bird Opening Mujannah Puzzle (Rated 1580): Trap a Piece — Decisive Material Gain

This middlegame puzzle is about turning a tactical pin and loose piece into a decisive material gain. White’s pieces are active, and the key idea is to exploit the fact that one black piece is overworked and vulnerable to being trapped or removed. When a pinned piece cannot move freely, tactical pressure often shifts from attack to simplification, letting you win material cleanly rather than forcing a direct mate.
