Queens Gambit Accepted Bogoljubow Defense Puzzle (Rated 1476): Win Material — Discovered Attack
This middlegame puzzle shows how a forcing sacrifice can expose the enemy king and overload the defender at the same time. White’s active queen and bishop coordinate against the black king, while Black’s queen is tied to a key defensive task. The key idea is that one tactical shot can create a discovered attack, forcing the king to respond and leaving a major piece vulnerable. The result is a clean winning combination based on king safety and piece coordination.
