How can the "opening book competition" >>factor be removed? Is it sensible to do this? It isn't a serious problem but not for the reason that Tom gave. All programs have learning features whether it is a book learning feature or a middle game learning feature. The 2 are combined in M-Chess 7.1 so that they feed off each other. One of my wishes for Crafty is to be able to actually learn the openings by extending Crafty's book the way that M-Chess does it. However in a short computer chess tournament learning is of little importance. Therefore opening book preparation for comp-comp tournaments takes on the importance that it does for GM play. Hiarcs 6 lost a game in KK Kup 2 directly attributed to a bad opening. -- Komputer Korner
