Frankenstein Dracula Variation Puzzle (Rated 1132): Fork — Vienna Game
A discovered attack occurs when one piece moves aside and reveals a line from another piece. In this Vienna Game position, the queen’s placement creates unusual tactical pressure against the opposing queen, while the knight can move with check. That forcing move also attacks multiple targets, transforming Black’s active-looking setup into a tactical liability. The key idea is not a mating combination, but a winning combination that exploits king safety, a pin, and overloaded defensive resources.
