Learn How to Spot Mate in 3: Queen Sacrifice
This puzzle is a classic forcing sequence where material takes a back seat to king safety. White’s pieces are active, but Black’s king is vulnerable to a direct mating net because the back rank and key escape squares are restricted. The winning idea is to use a sacrifice to drag a defender away, then follow with a forcing rook invasion that leaves the king boxed in. In practical terms, this is the kind of pattern that appears in chess endgame and middlegame positions alike.
