Mate In 3 Puzzle (Rated 1231): Spot Mate in 3 — Queenside Attack

This classical chess puzzle is a forcing middlegame attack where the king is dragged into a mating net on the queenside. The key idea is not material gain, but coordination: a queen and supporting pieces work together to restrict escape squares, exploit weak squares, and convert an exposed king into a forced checkmate. In positions like this, a quiet-looking move can be the start of a decisive tactical sequence, especially when the opponent’s king lacks safe flight squares.
