Frankenstein Dracula Variation Puzzle (Rated 1358): Pin — Win Material

This Vienna Game puzzle illustrates how a tactical refutation can overturn an apparent material advantage. The key idea is to attack a vulnerable piece while creating a passed pawn with promotion potential. A pin and skewer work together: the queen appears to threaten the enemy king, but its position becomes a tactical liability. In the middlegame, forcing pawn captures, checks, and threats against overloaded defenders can expose hanging pieces and produce a decisive material gain.
