well, I doubt that it is doable. I once read that there are about as many
possible game-positions as atoms in the universe. If that is true, it's never
solveable as long the universe does not get some more atoms for the
tablebase-generator-program... :)
Because somehow the fifty-move counter must be a part of a position, you know
some positions might be mate, but only if the fifty-move counter is not bigger
then a special number.

Besides that -> a friend of mine gave me an explanation why the simulation-idea
of our life in the movie matrix is unlikely. Let's expect that you need more
then one atom to simulate one atom. Therefor a simulation of such a big thing
like the universe and how it is presented to us is VERY unlikely. I think this
is a very reasonable explanation.

Greets, Thomas
