Hi,

Joachim Rang confirmed that they are both identical regarding playing strength
there is nothing altered.

There will come 150 games more from Ray and also some from other testers for the
setting.

Concerning the setting I got some mails that the history threshold reducement
works better in combination with king safety 104. We would also have tested
this, but after all this nasty threads motivation from CEGT testers dropped to
zero. Maybe Ray still will do it for helping Fabien. We shall see, patience is
needed and no results anymore with less than 300 games. We learnt from that.

It is just frustrating to do many hours of work daily for organizing all and
only receive critics. I can only repeat, give to me any bigger database inside
or outside of CEGT and I will always find a few games that look strange for
whatever reasons, mybe bugs of the engine, maybe something with hardware or any
GUI. This is unavoidable with thousands of games and statisitically over many
games irrelevant. Trying to find something by all means, just because of
eagerness to see a certain setting perform better, it is easy to suggest or
allege dozens of reasons.

I answered again, to be polite and because of your own efforts, but please give
me some rest now from posting.

Best Regards
Heinz
