I don't think so. If you test, for example, Hiarcs 6 and Fritz 5 at
equal ply levels, H6 would win hands down. It's more a matter of
computing time.

Playing one of the best current programs against a state of the art of
some 15 years ago on equal platforms would be interesting. Say one of
the Sargon programs, also by the Spracklen like your Challenger, against
Rebel, Hiarcs, Mchess, Genius or Fritz. This might give us an idea about
the advances in programs during the last 15 years. It might also bring
some light about this discussion I had with Bob a few months ago, where
he said programs didn't improve qualitatively in this period of time and
I disagreed with him.
