Use the rook to attack pawns from the side.
A rook on the opponent’s second rank can attack pawns from the side and restrict the king. It needs access through a file and support against attacks. A second rook can help, but the opponent’s checks and passed pawns still matter.
Attack the pawn with your rook
Your rook attacks the pawn. The opponent must consider this threat; whether you can win it depends on the reply and any recapture.
