Anderssen’s Mate is a checkmate pattern that features a rook supported by a pawn as it checkmates the opposing king along the eighth rank from the corner. The pawn is then also defended by another piece or pawn. The pattern is named after Adolf Anderssen, a German chess master from the 19th century.
