This is a harder case that my current "knowledge" doesn't cover.  Black
has the right bishop for its rook pawns.  Of course white has the same
colored bishop and if they are traded, it is a draw because of simple
rook pawns left with the opposing king controlling the queening square.

I can fix this cheaply and will.  But it is simply a good illustration of
just how many special cases there are in endgames that computers have to
handle...

Be interesting to see if any program currently has this evaluation knowledge
to call this a draw, statically.  It is doable.
