Yes.  This is a really hard problem, and I haven't found a good way to deal with
it.  For
just a single endgame like KRPKR it isn't very hard to tune the scores to be
reasonably
consistent with the evaluation of more complicated endgames, but when you add
code
for more and more classes of endgames it becomes very complicated to make the
program handle the transitions between different endgames correctly.

If anyone has found a good way to handle this problem, I would be happy to learn
about it.
