Kb4 looks to be the only way to start... I'll keep looking at it...
be right back with more that I can get. for future reference, after the white monarch gets to b4, black's king casn not get on d1 again, or else Kc3 would win.

It looks like a draw

ex: 1.Bf3+ Ke1! 2.Ba5 Kf2 draw

if white doesn't start with Bf3+ black either promotes or exhanges the pawn for a bishop.

what about 1. Kb4?
I think white may win, just can't prove it...
yet. Edit: not 2. Ba5? but Bh4+! would win.

no!
white does win, and I will prove it by asking for black's move after Bb5+!

Kc2 is met by Ba4+ and Kc1 where there isa pin on the pawn...
WHITE WINS!!!

White's winning move is
1. Kb4
if 1. ... Kc2, then 2. Ba4+ Kc1 3. Bg5 king moves away, Kc3 wins
if 1. ... Kc1 then Bg5 followed by Ba4 no matter what
if 1. ... Ke1 2. Bh4+ Kf1 3. Bb5+ Kg4 4. Be2 and white wins
if 1. ... Ke2 2. Bb5+ and similar technique wins...
this is a won position for white.

with the ...Ke1! line blacks second move would be ...Kd1!. and thats a draw.
