1...Bd6 is wrong. I think, 1...Bb8 draws (I hope I remember this correctly from
an analysis I have done some time ago). At least no engine was able to win, and
also Miguel has given convincing arguments.
It will be better to start from the initial position of WAC 100, instead of the
setup positions from FEN strings, to exclude the posssibility of repetition of
the original position.
Otherwise, one could argue, that the position is won after Kb3 (which would be a
wrong argument for a chess engine in my opinion).
