Knight + rook + pawn: the king caught on a hook
A rook delivers check defended by a knight, with a pawn (or piece) blocking one of the king's flight squares, together forming a hook the king cannot wriggle off. Closely related to the Arabian: same rook + knight idea, but the king sits one square off the corner because a pawn is plugging the escape.
Take the knight with check. The rook arrives on the h-file with the knight on f6 already covering the king's only flight to g8.
Go on then, take it.

White to move. Black has just blasted into h3 with the knight. Time to return the favour, the king on h8 is stuck in the corner.
