Morphy's mate is a checkmate against a king in the corner in which a bishop gives check along the long diagonal while a rook controls the neighboring file. Morphy's mate is a checkmate against a king in the corner in which a bishop gives check along the long diagonal while a rook controls the neighboring file, and the king's own pawn blocks the last flight square. The [bishop](https://georgelichess.com/glossary/bishop.md) is the checking piece in this pattern. It strikes the king on h8 along the a1-h8 [diagonal](https://georgelichess.com/glossary/diagonal.md) and also covers g7. The rook stands on the g-file, where it takes g8 and adds a second guard to g7. The king's own pawn on h7 removes the last [square](https://georgelichess.com/glossary/square.md), and with g7 covered nothing can step in between. That division of labor, bishop checking and rook guarding, is what separates it from [Pillsbury's mate](https://georgelichess.com/glossary/pillsburys-mate.md), where the rook gives the check. The pattern grows out of attacks in which the defender's g-pawn has been exchanged or destroyed, leaving the king on h8 beside an open g-file. Once a rook controls that file, any bishop check on the long diagonal becomes a serious threat, so the attacker's task is to find a safe route for the bishop, often with a [capture](https://georgelichess.com/glossary/capture.md) or a [sacrifice](https://georgelichess.com/glossary/sacrifice.md) on f6. For the defender, the warning signs are an open g-file and an enemy bishop that can reach the long diagonal. Contesting the g-file with a rook, keeping a piece ready to block on g7, or pushing the h-pawn to give the king h7 all break the net. The quiet piece goes in first. If the bishop checks before the rook controls the g-file, the king simply walks to g8. ## Example position White plays Bf6#. The bishop checks along the long diagonal and covers g7, the rook on g1 controls the g-file including g8, and Black's own pawn on h7 takes the last square. Position (FEN): `2r4k/pp3p1p/8/8/7B/8/PP5P/6RK w - - 0 1` Compare it with [Opera mate](https://georgelichess.com/glossary/opera-mate.md). An opera mate is a back-rank checkmate in which a rook delivers mate on the eighth rank while a bishop guards that rook and also controls the square in front of the king. Compare it with [Battery](https://georgelichess.com/glossary/battery.md). A battery is two of your pieces lined up on one file, rank or diagonal, with the rear piece backing up the front one so that both press on the same target.
