Use a knight to restrict escapes for the rook.
A rook gives check while a knight takes away king escape squares. Another piece supports the checking rook. Each piece needs to be in place: moving one too early can leave the king an escape or allow a capture.
Give checkmate
Your rook gives checkmate. The opponent cannot capture it, block the check or move the king to safety.
