Ba2 suggests itself, however Ba2 Bb6 Bb3 Bc7 and how to make progress?
Ba2 Bb6 c7 Kd7 (Bxc7 Kc6 Kd8 b6 Bb8 Kb7) c8=Q+ Kxc8 Kxd6-this however is drawn! Black places his king on b6 and his bishop on g5 and there is no way to make progress. So clearly Ba2 fails as c7 doesn't work and black's king can't be forced to move. However what if there was a slight alteration to the final position? if a black pawn was on g5 then the bishop couldn't go there!! Thus I must conclude that g5 is the solution. g5! allows two continuations-hxg5 or fxg5. Leaving the pawn is a terrible idea as soon as a king reaches e6 a pawn will be won. (though I'll go down that line as well just to show it)
I think this is the accurate idea....
Dude you're a master, did you use a computer or are you just that good?
