GOGOD FEATURES ATOM BOMB GAME & MORE: The Summer 2005 update of Games of Go on Disk (GoGoD) is now available, reports T. Mark Hall. "This edition has 32,370 professional games and is backed by a massive encyclopedia of tournament data, features, commentaries, photos and reference tools covering all aspects of go." Of special interest is an extensive feature on go in wartime Japan, as this August is the 60th anniversary of the famous atom-bomb game. "GoGoD was asked to produce background material for a special exhibition on this game at the Imperial War Museum in London," explains Hall. See  An even longer feature covers larger-than-life go hero Inoue Genan Inseki. GoGod surveys the world of Edo go, covering gambling go "and oddities such as the first case of someone jailed for copying game records." Also included are newly-discovered games by old masters suc h as Genan, Shuwa and Jowa, adding to GoGod's collection of historical games. "However, the main focus this year has been on filling gaps in modern games - many from obscure sources - and the bulk of the additions has been there," says Hall, who adds that "an unusually large amount of tournament data" has also been added.

The E-Journal plans to provide expanded coverage of the Ing this year, with updates, photos and games posted online as well as in the EJ.

GO ONLINE: Web Site Updates
by Roy Laird
        Recent updates to include a clickable American go map, links to three new vendors with unique products, an article by a team of Microsoft programmers who are studying go, and a walk down memory lane.
        The new map makes finding an AGA chapter or go club as easy as clicking on  Just choose the state where you'd like to play and up pops a list with contact info. The clickable map is a dramatic improvement, thanks to the efforts of Sergej Zoubok, with help from Chuck Robbins. And when you do show up at a chapter or club, be sure to let them know you found them on our site! NOTE: any updates should be reported to
        We're finding more and more makers and distributors of go equipment these days, often because they ask us for a link. That's how we found out about GoFigure, a German company at that seems to specialize in boards and stones made from the light, fine-grained wood of the beech tree. Firebrand Chess at sells equipment for various games, and they're expanding their go inventory. One item that caught our eye is a floor board with collapsible legs. On the cyber-side, MoyoGo, like GoGod and Master Go is a game-based analysis tool. Users compares their games to a database of over 190,000 records. They must be on to something, because their Bayesian move prediction system has captured the attention of Thor Graepel and his colleagues at Microsoft UK. See their paper at for more information.
         History buffs and researchers can find lots to get excited about on our site. There's the E-Journal archive at, and the archive of material from old American Go Journals at (The archive of Journal covers alone is worth the click.) Various archival materials can be found at And of course there's the AGA Historical Archive at, Now it turns out that there's even an archive of the web site itself! Go to and put our URL in the "Search" window, and you'll find doz ens of snapshots of the site dating back to 1997. Our thanks to Steve Stringfellow for spotting this link!
