Mayet's Mate: bishop and rook row the king into the corner
Have you ever seen a king cornered in its own corner, with no square to flee to? That’s exactly what you achieve with Mayet’s Mate. It’s one of those mating patterns that, once you see them, you start looking for in all your games.
The idea is simple: a rook breaks in on the last rank and a bishop closes off the only diagonal escape. The opponent can’t do anything. Checkmate is inevitable.
The pattern of Mayet’s Mate
Let’s look at what elements you need for this to work:
- The king is in the corner (a8 or equivalent after castling long).
- A piece of the opponent’s own blocks b8 (knights, bishops, or pawns).
- The attacking bishop controls the b7-c6 diagonal (or equivalent), blocking the king’s escape.
- The rook delivers checkmate on a8 (or on the last rank).
Notice the key difference from the back-rank mate: here the bishop blocks a diagonal escape square, not just the rank. That’s what makes this pattern special.
The pattern in action
Let’s look at a practical example. Play it out and see how simple it is to execute once your pieces are well placed.
You play White. The black king is on a8, blocked by its own pawn on b7. The bishop on b6 controls the diagonal covering a7. Bring the rook from d1 to d8 to deliver checkmate along the eighth rank.
Why the bishop is essential
What would happen without the bishop? The king would escape to a7 when the rook entered on the 8th rank. One move and the mate would vanish.
The bishop on b6 closes off that option. It controls the b6-a7 diagonal and leaves the king with no way out.
After Rd8+, the king on a8 has three squares and none of them work:
- b8: covered by the rook on d8 (same 8th rank: d8-c8-b8 ✓)
- a7: the white bishop on b6 covers a7 (diagonal: b6-a7 ✓)
- b7: its own black pawn ✓ (blocked)
Mate. That clean.
The bishop-rook cooperation
This pattern shows you something fundamental about how pieces cooperate. The rook acts along straight lines, the bishop along diagonals. Together they cover all four types of lines on the board.
When the king is in a corner and can’t move in a straight line or diagonally, there’s no escape. Once you master this coordination, you’ll start seeing these opportunities well before they arrive.
The variant with a blocking pawn
In real games, it’s more common for the king to be on a8 blocked by its own pawn on a7 and pawns on b7 or b6. The rook enters from the a-file or the 8th rank, and the bishop covers the diagonal escapes.
The essence doesn’t change: rook + bishop = complete control of every angle around the king in the corner. That’s the formula.
How to prepare Mayet’s Mate
Now that you know the pattern, here’s how to reach it in a real game:
- Provoke the opponent’s long castling, or wait for the king to end up on the queenside.
- Activate the bishop on the long diagonal aiming at b7 (or b2 if the pieces are mirrored).
- Open the a-file with trades or with the a4xa5 advance.
- Place the rook on the a-file or on the eighth rank to break in.
The sign that the mate is close: the enemy king is in the corner and its only free square is a diagonal your bishop already controls. At that moment, a sacrifice of material to speed up the attack might be the right move. When you see that position, act fast.

Preguntas frecuentes
What is Mayet's Mate?
Mayet's Mate is a checkmate pattern where a bishop controls the diagonal that blocks one of the king's escape squares, and a rook delivers checkmate on the last rank. The king ends up trapped in the corner by its own pieces and the bishop's control.
Who was Mayet?
Carl Mayet (1810-1868) was a German chess master who played important games during the 19th century. Although he wasn't the strongest player of his time, several tactical patterns from his games have been documented under his name.
How is Mayet's Mate different from Morphy's Mate?
They're similar but with different geometry. In Morphy's Mate the bishop covers the diagonal toward g7 (blocking that escape). In Mayet's Mate, the bishop covers the diagonal toward b7 or the long diagonal, blocking the king's path toward the central squares.
When does Mayet's Mate occur?
It occurs when the enemy king has castled long and is in the a8 corner (or equivalent), with its own pieces or pawns blocking the adjacent squares, and the attacking bishop controls the diagonal that blocks the last escape square.
