Back-Rank Mate
A rook or queen attacks along the back rank while the king's own pawn shield removes its escape squares.

A back-rank mate happens when a rook or queen gives check along the defender's first rank and the king cannot step forward because its own pawns occupy the nearby squares. The pawn shield that normally protects the king becomes a cage.
Look for a king on its home rank, three pawns or other pieces blocking the rank above it, and an open file or rank that an enemy rook or queen can enter. Then check whether the heavy piece can reach the back rank with protection or from a square where the king cannot capture it.
In the playable position, White's rook moves from e1 to e8. The rook attacks the king across the eighth rank, while Black's pawns on f7, g7, and h7 occupy all forward escape squares. With no capture, block, or king move available, Re8 is checkmate.
Before a back-rank threat becomes decisive, a pawn move such as h3, h6, g3, or g6 can create luft, an escape square for the king. Also watch open files, keep a defender on the entry square, and calculate whether a tempting rook move leaves your own back rank exposed.
The final check is delivered along the rank where the king began the game: White's first rank or Black's eighth rank.
Create a safe flight square, guard the opponent's entry squares, contest open files, and avoid moving the last defender away from the back rank without calculating the consequence.
