Checkmate With Queen Puzzle (Rated 1500): Mate in 4 — Queen Sacrifice
This chess puzzle is a classic mating attack built around king safety and forcing checks. Black’s active rook and queen create immediate pressure, while White’s king is stuck in the center with limited shelter. The key idea is to use forcing moves to drag the king into a vulnerable square, then coordinate the queen and rook to finish the attack. In practical classical chess, these patterns often appear when one side has an exposed king and loose pawns.
