Thanks again for the interesting results. I think the performance
is somewhat tilt because of the good results against the top engines.
I don't know Nimzo 2000 (Is this commercial?), however I have reports of
good results against it. But the result against Crafty certainly is not
that easy to reproduce.
Or it was luckier with black?
Thanks to Mogens for his efforts for the book. Also he has taken the
time, to make the original data available to me (which was much
more complicated, than it sounds).
BTW. I have seen some test results of you at Frank's site. They are
available as an Excel File. Is it possible to make them available
in ASCII (or mailing them to me in (zipped) ASCII). I can't read .xls ...
Regards,
Dieter

Yes it is..

Perhaps using another setting?
Seriously, besides extending Null move to 4, reducing pval since to help against Crafty..

Interesting. I increased pval once (it was not user accesible at the time).
Then I had a very nice series against Crafty, no loss in 10 games (G/60).
I never touched pval again ...
Perhaps my conclusion, that the new value was better, is wrong. I will try
a lower value some time.

Before null move 4?
Well with null move extended to 4, it might be different..Anyway, I lowered it a little only..0.9 or 0.8
