Sicilian Defense Mate In 3 Puzzle (Rated 969): Spot Mate in 3 — Hanging Piece
This middlegame puzzle is a sharp example of how a hanging piece can decide the game when king safety is already fragile. White’s king looks safe, but the back rank and the h-file are vulnerable, and Black’s queen can exploit the loose rook on h1 to force a mating net. The position rewards tactical awareness over material count: once the first forcing check lands, the defender’s replies are heavily restricted and the attack becomes unstoppable.
