Learn How to Spot Mate in 1: Back Rank Mate
This middlegame puzzle is a classic example of a forced mate where king safety collapses in one move. White’s heavy pieces are active, the black king has limited escape squares, and the back rank is vulnerable because the defending pieces are overloaded or pinned. In positions like this, the strongest move is often a quiet-looking rook move that becomes decisive because it seals every flight square and exploits the exposed king.
