There shouldn't be, since the programs are playing chess better and better, they
should find the same rules of thumb work as work with humans.

I think it might be useful to fudge occasionally though.  You can take a
position that a person would say is even, or perhaps worse for white, and yet a
computer playing black against a human will be worse off.  So perhaps you try to
teach the computer to avoid these positions even if they are objectively better.

The same could be true of material values, if a program is ham-handed about
handling a bishop and a knight, maybe you would teach it to prefer a rook and a
pawn.
