Queens Pawn Game Accelerated London System Exposed King Puzzle (Rated 1376): Spot Hook Mate — Mate in 3

This puzzle is a classic hook mate pattern in a sharp middlegame. White’s attack works because the black king’s shelter is weakened by advanced pawns, creating an exposed king with limited escape squares. The key idea is to use a forcing queen sacrifice to drag a defender away, then bring the rook in with check. These patterns often appear in classical chess when king safety matters more than material.
