OK, I think one should look only on his side and not criticize others...do you
understand what I mean?
Everybody know how good is Jeroem, still when you make a book for a chess
program you may experience that sometimes things do not work as expected. This
can happen to everybody and I do not see why criticize a book maker for those
things...
I always said that the opening book is part of a chess program and an important
part even if not the most important one which is the chess engine.
For me to evaluate a chess program without the opening book is like to evaluate
an airplane without the wings...it makes no sense.

I think there should be a limit to that. I would say no more than 2 programs and
the book should not be exactly the same.
I mean for me it is a sort of competition with other book makers. If I am
partecipating with one program only and another with 3 or more he has more
chances to win and so the result would be less important...I hope you understand
what I mean.
If the book is made by the same team for all chess programs, how can one call
himself maker of the opening book who got the title? Of course he got it...how
could have been otherwise?

Yes, this is unfair to me.
Also I do not see how this can be done (allowed) without the permission of the
author...

This is a very good question!
I always said, since 1978, that a good opening book is essential in today chess
programs. It is even more today because the programs are stronger and there are
faster hardwares.
So, now it shoud be clearified what a good opening book is. To me a good opening
book is something that helps the program to play better and score better.
This means that even a small book which brings to positions more suitable to a
specific chess program is a good book. It could be the best one for that
program.
