Learn How to Back Rank Mate: Endgame Pin
This chess endgame puzzle is a classic forcing sequence built around king safety and a pinned rook. White’s king has limited escape squares, while the back rank becomes vulnerable because the defending rook cannot freely move. The key idea is to use a forcing check to drag the king into a tighter box, then exploit the pinned piece to deliver mate. In classical chess, these patterns often appear when material is balanced but one side’s pieces are poorly coordinated.
