Hi, Guy Haworth has asked me to take the baton from him and organize making this wonderful new tool available to the World Team in the Kasparov vs. The World interactive game. At this point I am wondering about the following: 1. It is my understanding that Crafty needs minor modifications before it could be used with the new KQQKQQ tablebases. When will this happen? I saw Robert's post in this thread about a new version of Crafty being readied last night (Sep 22). 2. Is there any change in Crafty's system requirements when one uses it with the 6-man tablebases? 3. The tablebases are very large, and downloading them is not an option for most users. Is there a chance of having them available on CDs? My plan is to announce the availability of Crafty and the four-Queen tablebases on the World Team Strategy Bulletin Board http://bbs.msnbc.com/bbs/kasparov-team/index.asp after all the details have been worked out at this forum. I would like to have a few chess computer enthusiasts to take on the challenge of installing the new Crafty with the 6-man EGTBs and making them available to the World Team. Please advise as to the above questions on this board or via e-mail (pmarko@netcom.ca). Thank you and best regards, Peter On September 22, 1999 at 09:35:46, guy haworth wrote: >This note contains a request - for Robert Hyatt I think ... > >As CCC readers may be aware, Eugene Nalimov and Christoph Wirth have >independently created a complete and self-consistent KQQKQQ endgame database. > >Both authors responded readily to the request of the World TEam (in GK-v-WT) and >their achievements are without parallel.
