When I play the above move, I get a mate score from crafty. ie:
after Bd3, ...
(4) 17-> 51.30 -Mat40 1. ... Ke3 2. Bf1 Kf2 3. c5 Kxf1 4.
cxd6 <HT>
(which comes from tablebases of course...)
Kf2 then leads to a mate in 39...
3. Bh3 is not the move for white however... that leads to a repetition. white
plays c5 to stay on the track to mating... Bh3 will also mate, but only after
going through the 2-fold repetition first, and wasting time...
