Checkmate mix (3)

Another exercise with mate-in-one puzzles. This time the goals is to achieve checkmate with a rook, bishop and pawn. Once more, the positions are very similar.

Take a look at the examples.
Three of the five pieces are on the same squares. But the white king and the bishop have a different place.

It is important that you get your pieces to work well together. Attack the king from close by or from a distance.
But make sure you don't let the king escape! If you move a piece that controls a flight square of the king, the king may get away. And you don't want that!
Does the king still have escape squares? Try to control these first.

What do you have to do?

Checkmate the black king. Have the rook, bishop and pawn team up.
