Slav Defense Diemer Gambit Puzzle (Rated 1176): Win Material — Discovered Attack

This middlegame puzzle shows a classic attacking idea: use a forcing sacrifice to drag the king into a vulnerable square, then win material with a discovered attack on the queen. White’s pieces are coordinated around the enemy king and queen, and the key is that the opponent’s queen is overloaded while the king’s shelter is weakened. The combination is not about long-term maneuvering; it is about creating a direct tactical sequence that converts pressure into a decisive material advantage.
