Learn How to Force Mate in 4: Queen Sacrifice
This chess endgame puzzle is a classic forcing attack where material is secondary to king safety. White’s queen and rook coordinate to create a mating net against the exposed black king, and the key idea is a sacrifice that drags a defender away from the back rank. Once the king is pulled into the open, the remaining rook invasion becomes decisive. This is the kind of tactical finish you often see in classical chess and strong middlegame-to-endgame transitions.
