Learn How to Mate in 2: Back Rank Mate
This chess endgame puzzle is a forcing tactical finish built around king safety, piece activity, and a trapped defender. White’s rook is active on the seventh rank, and the black king has very limited escape squares because its own pieces and pawns restrict movement. In positions like this, the strongest move is often a check that forces a reply and then clears the way for a direct finish. The key idea is to use coordination, not material, to create a mating net.
