Checkmate pattern
Anastasia’s Mate: Knight and Rook Trap the King
Published Updated
Anastasia’s mate checkmates a king against the side of the board using a knight and rook. In the familiar White attack, a knight on e7 covers g8 and g6; the king is drawn onto the h-file, often by a queen sacrifice on h7, and a rook checks along that file. The traditional name is usually traced to the pattern’s appearance in Wilhelm Heinse’s 1803 novel Anastasia und das Schachspiel.

The anatomy of the pattern
In the model geometry, a knight on e7 controls g8 and g6, the two flight squares beside a king on h7. A black pawn on g7 occupies the remaining adjacent square. A rook can then mate along the h-file if the line is clear, the rook is safe, and no capture or interposition answers the check. The familiar way to draw the king to h7 is a queen sacrifice there, but the final geometry is what defines the pattern.
The classic execution
The position below has the familiar machinery: a knight on f5 one hop from e7, a queen on the b1–h7 diagonal, and a rook lifted to the third rank. After 1.Ne7+, Black chooses 1…Kh8; 1…Kf8 is the defensive alternative discussed below. The corner move allows 2.Qxh7+ Kxh7 3.Rh3#. In the final position, g8 and g6 belong to the knight, g7 is occupied by Black’s pawn, and the rook controls the h-file.
Play the finish yourself
Take over after 1.Ne7+ Kh8 and play both sides: sacrifice the queen on h7, recapture with the king, and land the rook mate. After the final move, account for g8, g7 and g6 and confirm why the checking rook cannot be taken.
How to spot it coming
- In the illustrated version, your knight can reach e7 with check, usually from f5 or d5.
- The enemy king is castled short with its h-pawn still home and the g7 pawn blocking the escape.
- You have a rook lift available (Re3–h3, Ra4–h4) or an open h-file for the queen or rook.
- A queen or bishop hits h7, so the king can be dragged onto the file by a sacrifice.
The defensive resource
In the worked position, 1…Kf8 after 1.Ne7+ avoids the corner and therefore the mating pattern, though White can take the c8-rook with 2.Nxc8 and gain the exchange. In other positions Kf8 may be illegal or inferior, so calculate the available king moves rather than memorising one defence. Earlier resources include challenging the rook lift, controlling h7, exchanging the attacking knight, or creating a genuine flight square before the forcing sequence begins.
