Under normal circumstances this is an win for the stronger side. In this position black sets its hope on the outside passer. If white would have a knight, his advantage would be reduced but actually with his bishop he has little problems to stop this pawn and attack at the same time. An easy win for white in a game between strong players. His general plan is to force the exchange of the rooks with threats, then enter blacks position by creating zugwang posiions.
