Queens Pawn Game Mate In 4 Intermediate Puzzle (Rated 1491): Spot a Mate in 4 — Queen Sacrifice

This middlegame puzzle comes from a Queen's Pawn Game structure where king safety matters more than material. White’s pieces are coordinated around the enemy king, and the key idea is to use a forcing queen move to drag the king into a vulnerable square. Once the king is exposed, the bishop and queen work together to exploit the weakened dark squares and the pinned g-pawn. The position is a classic example of a tactical mating net built from pressure, not a random attack.
