Use a knight to finish against a cornered king.
A rook or queen restricts the king near a corner, and a knight gives the final check. The knight’s check cannot be blocked. The other pieces must cover the king’s escapes and prevent a capture of the knight.
Sacrifice your rook to continue the attack
If the pawn takes your rook, your queen can give check. In this continuation, your pieces keep attacking and give checkmate.
