DOUBLE THE FUN AT YOUTH CAMPS: Go-playing youngsters who haven't signed up for this year's Youth Go Camps will want to start making plans now, reports Jon Boley. "This year we are extremely fortunate to offer Camps on both the East Coast and West Coast," says Boley, who's returning as Director for the West Coast camp at Mills College in Oakland California. "On the East Coast we will have Feng Yun, 9P, teaching alongside Bruce Wilcox," says Boley. "Feng Yun has taught some of the strongest youth in the United States and teaches go at her school in New Jersey." On the West Coast, Mingjiu Jiang 9P and Jin Chen 6d are returning this year. The East Coast Camp runs July 2-9 and the West Coast July 16-23. Check out photos, a video and download application forms (scholarships are available!) at

ORDERS OF MAGNITUDE: "You guys are just not having any luck with math!," writes Roy Schmidt. "Hot on the heels of the 3+2 = 6 apology, you run Roy Laird's news about solving 5x5 go.  He says 'At about a quarter of the full-board version, 5x5 go is miniscule...'  5/19 might be close to 1/4, but when we square it, it's closer to 1/16:  that is, 25/361 = about 1/14." Adds Kirk Martinez, "5x5 go has on the order of 25 (factorial) possible game paths, whereas 19x19 go has on the order of 361, which is unfathomably more complex - 'orders of magnitude' does not even do it justice.  The two games are in different universes." Martinez goes on to say that "It would be very interesting to hear more details from (Dr. van der Werf)  about recent progress on solving 6x6 and 7x7 go, (as well as) any communication he might have with Mr. Maasaki."

ONLINE GO: 5x5 Go Updated, EJ Archived & On CD
by Roy Laird
      Our sharp-eyed readers (see above) are of course quite correct (I was inexplicably thinking of a 9x9 board). Fortunately, my column provoked some interesting follow-ups, including inspiring Myron Souris, the man behind the "problem of the Week" series on the AGA's home page, to discuss the unexpected complexity he's found on boards as small as 2x2.  To download this analysis, go to
      Dr. van der Werf successfully defended his dissertation on "AI Techniques in the game of Go" in January.  He has written extensively on the subject and you can visit his home page at for a link to a bibliography which includes the full text of many publications.  When I asked how MIGOS has done against human opponents, van der Werf told the E-Journal: "A while ago Migos played two gam es for a radio interview against Robert Rehm a former Dutch champion, 5 dan, 2508 EGF. The first game Migos started with c3 and, not surprisingly, won by 25 points. For the second game I manually played MIGOS' first move on c2 so that Robert would have a chance and both players could make a living group. This game ended with the optimal result of a 3 point win for black (much like the example shown on my website). Robert did not make any mistakes. So far Migos has not faced a human opponent for the b2 opening (except for myself, ~1k). The main reason is that it takes quite long to play a game (which is annoying for a radio interview). However, I expect that strong human players should also be able to play that opening without mistakes (although they will not be as sure as my program :-))."
      Did you know that you can look up any issue of The American Go E-Journal?  At /EJournal/archive/EJarchive.asp, you will find a link to, which maintained an archive from the EJ's inception in 2001 to match 2004, and a list that picks up from that issue onward.
      Another way to view the EJ's contents is on the CD-ROM in the AGA Yearbook.  Go to to see the complete contents of last year's CD -- except the games and problems of course!  This year's edition is in the mail now and it's free to full members of the AGA.
