Mate In 3 Puzzle (Rated 1236): Force Mate in 3 — Queen Sacrifice

This chess endgame puzzle is a classic forcing sequence where the queen dominates the king’s escape squares. The key idea is to use checks that keep the opponent’s king boxed in while also exploiting a pinned defender and a trapped minor piece. In classical chess, these patterns often appear when material is down but the enemy king is exposed. The winning method is not about winning more material first; it is about creating an unavoidable mating net.
