The hook mate

Three pieces, each one safe only because of the one behind it. Take any link out and the whole thing is a blunder.

The pattern

abcdefgh12345678
The pattern, finished. The black king on e7 is in check from the rook on e8, which the knight on f6 defends. It has eight squares to try and none of them work: d8, e6 and f8 are covered by the rook on e8; d6 is covered by the pawn on e5; d7 is covered by the knight on f6; f7 is blocked by its own pawn; the rook on e8 cannot be taken, because the knight on f6 defends it; the knight on f6 cannot be taken, because the pawn on e5 defends it.

The rook stands next to the king and checks. A knight defends the rook, so the king cannot take it. A pawn defends the knight, and covers a flight square of its own into the bargain. That chain is what the name describes.

The knight is the piece that makes this different from an ordinary rook check. From two squares away it defends the rook and takes a square beside the king at the same time, which is the same trick the Arabian mate uses, in a position where the king is in the open rather than in a corner.

The pawn matters more than it looks. In every position on this page there is a pawn covering an escape square, and it is usually a pawn the attacker pushed several moves earlier for a completely different reason. The mate is often available because of a pawn nobody was thinking about.

What is always true

Each line below was tested against all 11 positions in this course that show the pattern, using the same rules engine the trainer runs on. The build stops if any of them is ever false, so the count beside each one is the real count.

Questions people ask

What is the hook mate in chess?

A checkmate delivered by a rook on the square beside the king, defended by a knight, which is in turn defended by a pawn that also covers one of the king's escape squares.

How is the hook mate different from the Arabian mate?

Both are a rook next to the king defended by a knight. The hook mate also needs a pawn, and its king is usually in the open rather than in a corner, where the edges of the board would do the pawn's job.
