Learn How to Clear the Back Rank: Mate in 2
This puzzle is a classic clearance mate pattern in a middlegame setting. White’s pieces are active, but Black’s king is vulnerable because key squares and defensive lines are overloaded. The winning idea uses a forcing sacrifice to drag a defender away, opening a route for the rook to deliver checkmate. Patterns like this often appear in classical chess and are easy to miss if you focus only on material instead of king safety and piece coordination.
