French Defense Diemer Duhm Gambit Accepted Puzzle (Rated 904): Win Material — Greek Gift Attack

This middlegame puzzle shows a classic kingside attacking idea where White uses piece activity and king safety to create a forcing tactical sequence. The key is that Black’s queen has become overextended in the center, while White’s knight and bishop coordinate against the enemy king’s shelter. Even though the position is not a mating finish, the attack wins material by exploiting a vulnerable king position, a pinned pawn, and a trapped queen. It is a strong example of how a tactical shot can convert into a decisive advantage.
