A back-rank mate is delivered by a rook or a queen along the first rank, against a king that is hemmed in by its own unmoved pawns. It is the most common mating pattern in club chess for a simple reason: castling puts the king behind three pawns, and if those pawns never move, the king has no escape square when the rank opens.

How to spot it

• The castled king still has all three pawns in front of it and no luft — no square to step up to.
• Only one piece guards the back rank, so removing or deflecting it opens the mate.
• You have a rook or queen that can reach the rank with check in one move.
• It is worth a sacrifice: giving up material to deflect the one defender is the standard way this happens.

A worked example

White: king h1, queen f1, bishop f3, pawns g2 and h2. Black: king g8, rook b1, pawns e6, f7, g6 and h6. Black to move.

1. Rxf1 takes the queen and checks along the first rank.
2. The white king cannot move: g2 and h2 are its own pawns, and g1 is covered by the rook that just landed on f1.
3. Nothing recaptures either — the bishop on f3 does not defend f1, and the king cannot reach it.

The idea The king was never in danger from across the board. It was in danger from its own pawns: one open rank, three pawns that never moved, and a single check ends the game.
