The problem is that a game is game... not a series of moves.  If you could
prove that program "X" plays every move in a DB game except move N, and then
you could prove that move N was better beyond any doubt, then you just proved
that in _that_ position (only) program X appears to know a bit more.  I don't
think you will ever find a tactical move that program X can find that DB didn't,
so you are going to be looking at positional stuff only.  And proving that
one positional move is better than another is a _very_ non-trivial thing to
do...
