Rook vs Bishop
Except you need to use both colour squares to drive the king back. You need to get the kings in opposition in a rook and king ending. You cant do this if there's a bishop controlling important squares.
It's a book draw in most positions i think.
[edit] The position shown is definitely a draw. I checked it in a tablebase just to make sure.
I finished a game of rook and king vs bishop and king only, is there any general way to force mate if you are a rook and king?
