Queens Gambit Accepted Saduleto Variation Mate In 1 Beginner Puzzle (Rated 945): Epaulette Mate — Queen Sacrifice

This puzzle is a classic epaulette mate pattern in a sharp middlegame. The key idea is that the enemy king is boxed in by its own pieces, leaving no safe escape squares once the checking piece lands on the critical square. Even though material may look balanced or even favor the defender, king safety overrides everything when the king is trapped by surrounding pieces and the final check cannot be met by capture, block, or flight.
