Rook and knight mate in the corner
A rook delivers check on the h-file with the knight a knight's move away protecting it. The king has no escape: the rook checks, the knight covers the king's flight square and defends the rook. One of the oldest named patterns, dating back centuries to Arabic chess problems.
Rook delivers the check, knight covers the escape square.
