The epaulette mate

The only mate on this list that the defender mostly builds. One piece gives the check; the other two belong to the player being mated.

The pattern

The pattern, finished. The black king on f8 is in check from the rook on f5. It has five squares to try and none of them work: e7 and f7 are covered by the rook on c7; e8, g7 and g8 are blocked by its own pieces.

The king stands between two of its own pieces on the same line, classically the two rooks on d8 and f8 after the king has been forced back to e8. A queen or a rook then checks from directly in front of it.

There is nowhere sideways, because the king's own pieces are there. There is nowhere forward, because the checking piece is there and is defended or out of reach. And the squares diagonally forward are on the checking piece's lines. One piece from the attacking side does all of it.

The practical value is in the recognising, not the forcing. A king with pieces on both sides of it is a king that is one check away from mate at all times, and the whole trick is noticing that the position you already have is that position.

What is always true

Each line below was tested against all 24 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 queen or a rook 24/24
The king is flanked, on one line, by exactly two pieces of its own 24/24
The check comes along the line perpendicular to that pair 24/24

How to spot it

A king that has been driven back to its own first rank with rooks still on both sides of it. Nothing else on the board matters.
Any check you can give on the file in front of that king, even a check that hangs the piece, because it may not be capturable.
The defensive version. If your own king is sitting between two of your rooks, move one of them or make luft before the position becomes forced.
Pawns as well as rooks. The blockers do not have to be major pieces; two pawns either side of a king in the middle of the board do the same job.

Where the name comes from

An epaulette is the shoulder board on a dress uniform, and the two pieces standing either side of the king are the shoulder boards. It is one of the few chess names that describes a picture rather than a person.

Easy to confuse with

These are the patterns Epaulette Mate gets mistaken for. The difference is usually one piece or one square.

Questions people ask

What is the epaulette mate?

A checkmate in which the king is boxed in by two of its own pieces standing either side of it on the same rank or file, while a queen or rook checks along the perpendicular line.

Why is it called the epaulette mate?

Because the two pieces flanking the king look like the epaulettes, the shoulder boards, on a uniform.

How do I avoid being mated this way?

Do not leave your king between two of your own pieces on the back rank when a major piece can reach the file in front of it. Moving one rook or making luft removes the pattern entirely.
