Subject: Fritz GUI and 1 MB bug

Hi all,

browsing through the messages from last weeks one word about my experiences and
those told to me by other CEGT testers.

If you use a ChessBase GUI before native Shredder 9 and never cared for
downloading a free and newer UCI.dll you will definitely encounter the 1 MB bug,
especially for Deep Sjeng,  Yace,  Pharaon and some others that are naturally
UCI. You could avoid this by configuring some engines with Wb2UCI adapter,  but
better simply download a new UCI.dll. All CEGT testers with Fritz GUI are using
a new UCI.dll and after checking the task manager many thousands of times we did
not encouter the 1 MB bug anymore.

Known testers like Claude Dubois have demonstrated with many hundred games that
with a new UCI.dll this problem is fixed. There will be other bugs like not
being able to handle games with more than 256 moves and so on, but there is no
flawless GUI up to now. It was claimed that UCI engines have disadvantage
against native engines. Why then does Fruit 2.1 perform so well also against
those? Should it not perform worse against them and better against other UCI
engines also allegedly handicapped.

I am not really a ChessBase fan and read a lot about lousy support for
custumers. Just to mention that CEGT testers of course also use Shredder Classic
GUI and Arena (depends on engines, that have to be tested,  as you can´t test a
few like Junior and Hiarcs in other GUI´s).

Moreover we are using shorter general books (not Nunn and Noomen positions
currently, although they are also fine), because we want to test mainly the
strength of the engine itself.  We do not like books adapted to certain
opponents or lines with 30 moves and more and we already have an endgame
position after this.

So this topic for me is finished. I am fed up with this discussions with many
who only like their own GUI, because their are many fine ones and will not
answer to responses where intentions are clear. In this forum there are
sometimes overaggressive people, so it is not my favourite one.

Best Regards
Heinz
