Learn How to Spot a Mate in 2: Queenside Attack
This classical chess puzzle is a forcing middlegame tactic where White uses an active rook and a queenside attack to create a mating net. The key idea is not material gain, but coordination: one piece invades with check, another piece is forced to respond, and the queen delivers the final blow. The position also shows how a sacrifice can be used to remove a defender and expose the king to a direct finish.
