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
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.
- The checking piece is a rook 11/11
- That rook stands on a square adjacent to the king 11/11
- A knight defends the rook 11/11
- A pawn covers at least one of the king's escape squares 11/11
How to spot it
- A knight of yours already defended by a pawn and within reach of the squares beside the enemy king. That is the hook; the rook comes last.
- An enemy king that has been pulled into the middle of the board, which is where this pattern lives.
- A rook with a route to a square adjacent to the king, however unsafe that square looks on its own.
- Advanced pawns of yours near the enemy king. They are the third link and they are the reason the pattern exists at all.

- Kill Box MateRook adjacent, queen a knight's move away
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.
