Blackmar Diemer Gambit Declined Intermediate Puzzle (Rated 1279): Win Material — Tactical Refutation
This middlegame puzzle is all about turning active piece placement into a decisive material gain. White’s queen and bishop create strong pressure around the enemy king, but the key idea is not a direct mating attack: it is a forcing sequence that exploits a skewer and a hanging piece. When the defender is overloaded, a tactical refutation can simplify the position while leaving one side with a winning material edge.
