Queen's Gambit Declined Puzzle (Rated 877): Crush the Kingside — Bishop Sacrifice

This classical chess middlegame shows a direct kingside attack built around piece activity and king safety. White’s pieces are coordinated to exploit dark-square weaknesses around the enemy king, while Black’s defenders are overloaded and short on active counterplay. The key idea is a forcing sacrifice that drags a defender away from the king’s shelter, creating a tactical entry point for the queen. In positions like this, the attack is stronger than static concerns such as an isolated pawn.
