What is Mayet's Mate?

Rook, supported by a bishop, delivering checkmate

Mayet's mate features a rook attacking the black king, supported by a bishop. This pattern often emerges after the black king has castled kingside in a fianchetto setup. White typically achieves this position following a sequence of sacrifices along the a-file or h-file. It is a variation of Anderssen's Mate and closely resembles the Opera Mate."
