Subject: Re: Creating Opening books ==> don't use CAP data.

Hello,

As with any other tool, if misused, CAP data might be harmful to your program's
success.  Many people have used the CAP data to great success within their
program, so I think that the problem is not with the CAP data, but in how you
are using it.

I would also like to say that I think your posts on this subject are verging on
hostile towards the CAP project and Dann.  Dann has done a lot of terrific work
for computer chess, and many people find the results of his CAP project
extremely useful.  This information is made freely available, with loads of
volunteer effort going into it.  It seems to me that complaining about it is in
very poor taste.

As far as hand generated books go, I think that most authors are willing to
accept the position that will occur maybe once every 100 games where the opening
book might be wrong, rather than have the opening book be 100% hand verified
(which doesn't necessarily even mean it's any better), and leaving book on move
3 or 4.  There is a compromise here - would you rather accept a small mistake
once every hundred games, or get generally smacked about in the opening in every
game?  I personally would prefer the former, and apparently so do most authors.


Regards,
Adrien.
