I already understood from a previous comment of you that the motivation for
testing personalities is very low and the only reason for testing one
personality that is not the default personality is because fruit is a special
case.

This was the reason for my question why do you test chessmaster personalities
and not the results of fruit.

Without that comment that already suggested that there is probably little chance
that you will test third personality of fruit I would probably not ask the
question about chessmaster personalities.



 Maybe Ray still will do it for helping Fabien. We shall see, patience is

Very good
Here is another idea that I suggest the CEGT
Never test future versions of Movei.

It is just frustrating to be attacked after trying to be productive.
I guess that people will learn never to check the games of CEGT and not to care
if there are errors.

 I can only repeat, give to me any bigger database inside

Note that I did not investigate most of the games.
I looked only at few games(I think less than 10 games) that fruit lost to see if
there is some problem and even in games that I looked at I did not look at most
of the game and I tried to see fast if I can find some error that I cannot
reproduce.

I do not know if there are problems in the other games and of course I learned
that it is better to tell nothing about problems to the CEGT and trying to check
if there are no errors in the games is a waste of time.
