Mating Pattern
Damiano's Mate
Damiano's Mate is one of the oldest recorded checkmating patterns, set down by Pedro Damiano in 1512. Its signature is a queen supported by a friendly pawn on the sixth rank, delivering mate right next to the enemy king. In the diagram White's pawn on g6 stands one square from Black's king and guards the h7 square, while the white queen waits on h5. Because the pawn defends the queen's landing square, White can crash into h7 and the king cannot strike back.

What Damiano's Mate is
Damiano's Mate is the pattern in which a queen, backed by a pawn on the sixth rank, mates on the h-file beside a castled king. The defining piece is that advanced pawn: here it sits on g6, one step from the black king on g8, and it guards h7. Because a friendly pawn already covers the square the queen will occupy, the queen can be thrown onto it with impunity, since the king dare not capture a protected attacker.
Everything depends on the g6 pawn. Remove it and Qxh7 would simply be met by the king taking the queen; with it, the same capture is checkmate. The pattern shows how a single advanced pawn can transform a queen from a piece the king could gobble into an untouchable executioner sitting on its doorstep. It is a textbook example of a supported piece delivering a short-range mate that the defending king is powerless to answer.
The line move by move
With White to move, the finish is a single blow: Qxh7#. The queen leaves h5, captures the black pawn on h7, and gives check from the square diagonally beside the king on g8. The move is a queen sacrifice in appearance only, because the pawn on g6 is defending h7. The king therefore cannot answer the check by capturing the queen, which is the entire point of the combination.
Now look at the king's escape squares. It cannot take on h7, and it cannot flee: f8 is occupied by its own rook, f7 by its own pawn, and both g7 and h8 are covered by the queen now standing on h7. No black piece can capture the queen, and against a check delivered from an adjacent square no interposition is possible. The king is mated on the move.
Using the pattern
In practice Damiano's Mate is usually the finish of a longer combination. In its classic full form the attacker first sacrifices a rook to rip open the h-file and drive the defence away, and only then brings the queen to the h-file for the mate on h7 or h8. The diagram isolates that clean finishing position so the essential mechanism, queen plus supporting pawn on the sixth, stands out on its own.
The practical signals are worth memorising. When you have a pawn planted on g6 and an open route for the queen to the h-file, the h7 and h8 squares become mating targets the king cannot defend. As the defender, treat an enemy pawn that reaches g6 as a serious warning, keep the h-file closed, and avoid letting your king be sealed in by its own rook and pawn as Black's is here.
Key ideas
- Damiano's Mate is a queen supported by a pawn on the sixth rank mating beside the enemy king.
- Here the g6 pawn guards h7, so Qxh7 is protected and the king cannot capture the queen.
- After Qxh7 the king on g8 is checked from an adjacent square with no way to block.
- Its flight squares fail: f8 and f7 hold its own rook and pawn, and the queen covers g7 and h8.
- The advanced supporting pawn is what turns a capturable queen into an untouchable mating piece.
- In full form the pattern follows a rook sacrifice that tears open the h-file for the queen.
