Again this is only so the CCC members can get an Idea NOT an exact assurance
that Program X is stronger than program Y. But in this particular case where
Fritz has its origianl version 8.008 and also version 8.0023 which Tony from
the SSDF is testing right now, we are not too sure if version 8.008 is really
stronger than version 8.0023. When Shredder 7 and Shredder 7.04 were tested
against all the three versions of Fritz, it gave us a clue with a small margin
of error that version 8.0.0.8 is the stonger against Shredder, but that doesn't
indicate that it is stronger overall against the rest of the programs.
Therefore, my little test will only give you a clue.

It all depends how much weaker, if the weaker program is more than 50 points
weaker, than the opening might not help the weaker program much. Just to give
you an escenario lets take List 5.04 with its opening book for instance, versus
shredder 7.04 without an opening book at all, if you match them in a 40 games
match i would not put my money on List 5.04. There is one major reason why you
can't depend on opening book too much

1st. The opening book could have been created by collecting openings from human
players, and of course these opening are NOT guarantee to be error free.

2nd. It is not clear if top programs such as shredder 7 or Fritz 8 are able to
create opening moves that could be better than those taken from humans players,
specially if the opening books were taken from games of players less than the
top 100 FIDE ranking.
