Four Knights Game Hanging Piece Puzzle (Rated 1055): Spot Mate in 1 — Hanging Piece Tactic

This middlegame puzzle is a classic example of king safety deciding the game immediately. White’s back rank and kingside pieces are loose, and the black queen has a direct route to the final blow. The key lesson is that a hanging piece can be more than a material target: if it also opens a mating line, the position can collapse at once. In classical chess, always check forcing moves before grabbing material.
