Hanging Piece Puzzle (Rated 694): Win Material — Cheapo

This middlegame puzzle demonstrates how quickly material can change when an undefended queen and an attacked piece coexist. White already has a material advantage, but the position demands accurate calculation because the bishop on b8 is under pressure from the rook. The key strategic idea is to identify the most valuable target, use check to gain time, and preserve the advantage while neutralizing the opponent’s tactical threat. This is a practical winning combination rather than a mating attack.
