Blackmar Diemer Gambit Accepted Kingside Attack Intermediate Puzzle (Rated 1103): Spot a Mate in 1 — Queen Sacrifice

This middlegame puzzle is a classic king-safety finish: White’s queen and bishop coordinate to overwhelm the dark squares around the black king. The key idea is that the enemy king has limited escape squares, while the defending pieces are overloaded and unable to cover the critical entry point. Even though material may be close, the attack is all about forcing the king into a mating net before any counterplay can begin.
