Go up one level in this thread


Letting Rybka use an optimized book is almost not fair for other programs.  It
is already way stronger than anything out there, and the only time it usually
loses is when it is caught with a book move.  Very rarely do you see Rybka get
outplayed in the middle game in an even position ... and I mean VERY VERY
RARELY.  Rybka was already beating any engine with its own native book very
handily, so now I guess things will really get ugly.  They might get even uglier
once the last few weaknesses of Rybka are covered (endgame knowledge).

I can assure you also, that this "public" book is not the best book that they
have.  The best book is kept for special tournaments.  But still it is a vast
improvement over anything out there.  The already lopsided tournament results
will be stretched even further.
