In engine vs. engine matches, Hiarcs 7.32 will destroy Fritz 5.32 most of the
time.  Hiarcs saves its hash tables between moves, Fritz starts from scratch at
the beginning of each move.  This in essence gives Hiarcs the equivalent of
pondering in the engine vs. engine matches.  In competition between the two
programs on separate machines, I believe that there is not much difference
between the two, maybe Hiarcs is a bit stronger.
