BS for its a draw.
Please post a line where either player wins, with the opponent making the following moves :
if Black : ...Bb5 first. Then, play any legal moves with the king ; if none is available, play the bishop on any square of the diagonal b5-f1 that is not under attack by White's king, and come back to b5 next move.
if White : Be3-b6 first, then any legal moves with the king. If none is available, it means the a5 pawn is not under attack (check it) so move the bishop along b6-g1 and back.
I agree to publicly bow to your skills and change my image picture to whatever you wish it to be if you manage it.
most probabl draw. if black palys smartly, can win.
