Damiano's mate
Also known as Damiano mate
Damiano's mate is a corner finish where a friendly pawn props up the queen as she settles on the square next to the enemy king. Because the pawn defends her, the king cannot take her, and with every flight square covered the game is over.

How it works
With the black king tucked into the corner on h8, the white queen drops onto h7 – the square right beside it. She is protected by the pawn on g6, so the king cannot capture her. From h7 the queen also covers g8 and g7, the only other squares the king might run to. With h7 occupied and defended, and both g-file escape squares controlled, the king has no legal move: checkmate.
How to spot it
Look for it when the enemy king is boxed into a corner (often h8 or h1) and you already have a pawn one diagonal step away – a pawn on g6 against a king on h8, for instance. That pawn is the key: it lets your queen sit on the square next to the king without being taken. Aim your queen at that adjacent square along an open rank or file, and check the king has no escape over the two neighbouring squares your queen will cover.
Key ideas
- A supporting pawn lets the queen sit safely on the square beside the king
- The cornered king's escape squares are all covered by the queen herself
- Works because the king cannot capture a defended queen
- Look for a pawn on g6 (or f6/h6) against a king on h8
- A close relative of Damiano's bishop mate
Famous example
Named after Pedro Damiano, the early-16th-century Portuguese author whose 1512 treatise catalogued such mating patterns. It is a cousin of Damiano's bishop mate, which uses a bishop and queen sacrifice to herd the king into the same corner finish.
