Learn How to Spot Mate in 2: Back Rank Mate
This chess endgame puzzle is a classic mating net built around a back rank weakness. White’s active rook and bishop coordinate to restrict the black king’s escape squares, while the black rook is overloaded by the need to defend the back rank. The key idea is that a forcing check can drag the defender onto a square where it becomes pinned or unable to keep guarding the mating line. In classical chess, these short tactical finishes often decide games immediately.
