Checkmate pattern

In chess, several checkmate patterns occur frequently, or are otherwise of such interest to scholars, so as to have acquired specific names in chess commentary. The diagrams that follow show these checkmates with White checkmating Black.

In Anastasia's mate, a knight and rook team up to trap the opposing king between the side of the board on one side and a friendly piece on the other. This checkmate got its name from the novel Anastasia und das Schachspiel by Johann Jakob Wilhelm Heinse.

In Anderssen's mate (named for Adolf Anderssen), the rook or queen is supported by a diagonally-attacking piece such as a pawn or bishop as it checkmates the opposing king along the eighth rank.

Sometimes a distinction is drawn between Anderssen's mate, where the rook is supported by a pawn (which itself is supported by another piece, as in the diagram), and Mayet's mate, where the rook is supported by a distant bishop.

In the Arabian mate, the knight and the rook team up to trap the opposing king on a corner of the board. The rook sits on a square adjacent to the king both to prevent escape along the diagonal and to deliver checkmate while the knight sits two squares away diagonally from the king to prevent escape on the square next to the king and to protect the rook.

The back-rank mate occurs when a rook or queen checkmates a king that is blocked in by friendly pieces (usually pawns) on his first rank.

The Bishop and knight checkmate occurs when the king teams up with a bishop and knight to force the opponent king to the corner of the board. The bishop and knight endgame can be difficult to master: some positions may require up to 34 moves of perfect play before checkmate can be delivered.

Blackburne's mate is named for Joseph Henry Blackburne and is a rare method of checkmating. The checkmate utilizes the black rook (it could be a bishop or queen instead) to confine the black king's escape to the f8 square. One of the bishops confines the black king's movement by operating at a distance, while the knight and the other bishop operate within close range. Threatening Blackburne's mate can be used to weaken Black's position.
