Frankenstein Dracula Variation Puzzle (Rated 1352): Win — Overloaded Defender

This middlegame puzzle illustrates how active pieces can outweigh a large material deficit. Black’s position contains a forcing tactical resource based on a bishop entering the king’s zone with check. The key idea is to exploit a relative pin, overload the queen, and use the open e-file to create a discovered attack against the exposed white queen. White’s extra material is less important because several pieces are passive and the king is vulnerable to coordinated threats.
