Hook Mate

The Hook Mate is a rook-and-knight checkmate against a king on the edge of the board. In the example below the rook checks down the h-file and covers g8 along the eighth rank, while the knight defends that rook and physically occupies the square beside the king. So far it resembles the Arabian Mate, but the Hook Mate carries one extra condition: a pawn has to defend that knight. The pawn supports the knight and the knight supports the rook, so the three pieces lock together in a chain.

How often does it show up

Of the 212,300 puzzles in this site's database, 379 (0.2%) carry the hook mate tag (counted August 2026), and 76.0% of them are tagged endgame against 23.5% middlegame.

That endgame share is the highest of the 19 named mates measured for these guides. The blind swine mate is next at 71.9%, then the triangle mate at 67.6%. 53.0% fall below rating 1200 and 44.6% are tagged mate in one.

Why it is mate

Take the squares around the h7 king one at a time.

• g8: attacked by the h8 rook along the eighth rank.
• g6: occupied by the white knight. Kxg6 is illegal because the h5 pawn defends it.
• g7: occupied by Black's own pawn.
• h6: nothing attacks this square right now. But stepping there empties h7, which opens the h8 rook's file all the way down to h6 - so the king would still be in check and cannot go.
• h8: the checking rook stands there, and Kxh8 is illegal because the g6 knight defends it.

There is no way to block either. h8 and h7 are adjacent, so there is no square in between to interpose on, and Black has no piece that can capture the rook.

Note how the jobs divide. The rook is what actually controls the flight squares - g8 directly, and h6 through the file the king itself would vacate. The knight blocks g6 with its own body and defends the rook. It is easy to assume the knight attacks g8 or h6, but from g6 a knight only reaches e5, e7, f4, f8, h4, and h8.

One pawn holds the whole thing up

The piece worth studying here is the pawn on h5. It sits two squares from the king and takes no part in the check or in covering flight squares, yet without it there is no mate.

Key piece

Shifting the pawn one square gives Black exactly one legal move, Kxg6, and that single move ends the attack. The knight is standing right where the king can reach it, blocking that square with its own body, and it is tied to defending the rook so it cannot step away. Something has to back it up, and that is the pawn's whole job. Pawn supports knight, knight supports rook: that chain is the skeleton of the Hook Mate.

Versus the Arabian Mate

Both patterns have the rook checking and the knight defending it; what differs is where the knight has to stand. In the Arabian it sits on f6, safely beyond the king's reach, and it attacks the g8 flight square directly. In the Hook the knight steps right next to the king on g6 and blocks that square with its body, leaving flight-square control to the rook - and putting itself where the king could capture it. The pawn covers that risk.

How to set it up

1. Push the enemy king to the edge. On the h- or a-file it has at most five squares to run to instead of eight, and only three in the corner.
2. Bring the knight to the square beside the king. Aim for a square like g6 that blocks a flight square with its body while also defending the square the rook needs.
3. Back that knight with a pawn. A knight that arrives before its pawn support can simply be captured by the king, so it is safer to have the pawn in place before the knight jumps in.
4. Bring the rook to the back rank with check. Confirm the square it lands on is one the knight defends.

Defending against it

• Look for the pawn behind the knight first. When an enemy knight heads for a square next to your king, whether a pawn defends that square decides whether you can take it. If none does, just take the knight.
• Get off the edge. A king on h7 or h2 is the precondition for this pattern. Step toward the center while you still have time and the pattern cannot arise.
• Think about the pawn in front of your king. In this diagram the g7 pawn seals a flight square for the defender. Pushing it is not automatically right, though - decide based on where the attacking pieces are aimed.
