Learn How to Kill Box Mate: Back Rank Mate
This chess endgame puzzle is a classic kill box mate pattern: the enemy king is boxed in by its own pieces and pawns, leaving only one narrow escape square. In positions like this, a forcing check can drive the king onto a file or rank where a rook delivers the final blow. Even in a winning middlegame or endgame, king safety can outweigh material when the defender has no luft and no useful interposition.
