Vulture Defense Puzzle (Rated 1397): Refute a Hanging Piece — Tactical Refutation

This middlegame puzzle is about turning king safety and piece activity into a decisive material gain. White’s queen and bishop coordinate aggressively around the black king, while Black’s last move leaves a piece exposed and overworked. The key idea is to notice when a defended-looking piece is actually vulnerable because its capture opens lines or removes a key defender. In classical chess, these moments often decide the game immediately through clean calculation rather than long maneuvering.
