To me it sounded like a even headed gracious report ... no midlife crisis here.
I still think that Shredder will kick any programs butt in a tournament with
many games. I am looking forward to trying out the new Zappa in a long
tournament with normal even books.  I am still not convinced it is the strongest
engine, even though I thought it played great.  But it really was never in any
trouble out of the openings and was extremely well prepared.  I don't want to
belittle Zappa's achievement at all, I think they were great.  But a WCCC title
doesn't automatically mean you have the strongest engine.

I believe one of the main reasons Junior and Shredder's performance seemed
sub-par was because if you go to the engine room on Playchess, almost every
engine is playing one of these two.  So it is easy to play thousands of
automatic games and see which lines these 2 programs play poorly and cook books
against them.  Now Zappa is the new champ and people will probe for its
weaknesses once the program is available for public download.

By far the most impressive program in my opinion was Fruit.  It is using a
revolutionary type of evaluation that in many ways seems kamakazee.  Yet it
still manages to prove that its evaluation was correct.  I think it will be the
most difficult engine for other engines to deal with because most engines are
not even considering moves that it chooses.  This is why it can get away with
dramatically inferior hardware and no EGTB and books off the shelf that are not
tuned to its weird evaluations and still almost win the WCCC.  A Fruit with EGTB
and multiprocessor support with a Playchess engine room tested book will be a
formidable opponent.
