Frankenstein Dracula Variation Puzzle (Rated 936): Win — Discovered Attack

A discovered attack is a tactical pattern in which one piece moves away and reveals an attack from another piece behind it. In this middlegame position, the critical move creates check while uncovering a powerful queen attack. White’s exposed tactical coordination means the apparent extra material does not guarantee safety. The combination exploits king pressure, a vulnerable queen, and overloaded defenders to convert activity into a decisive material gain.
