Knight cuts off escape, rook delivers on the h-file
A knight cuts off the king's escape squares while a rook or queen delivers check from the edge file. Named after Wilhelm Heinse's 1803 novel 'Anastasia und das Schachspiel,' the canonical shape is a knight on e7 (or e2) covering g6 and g8 around a king on h7, with a rook arriving on the h-file. The mating piece often gets there via a sacrifice that clears the diagonal or rank.
