chipuni: How is this defined as best play? How was this determined?

PurpleHaze: A group of New Zealand dan players over the course of several years with the assistance of computers and a few Japanese pros.

gimpf: Maybe for such things we should add always when possible a bibliographical reference. Don't trust best play by amateurs...

RobertJasiek: Anything about perfect play without a rules text and a mathematical proof is not serious.

PurpleHaze: Fine, I looked up my notes: the rule set is NZ (no suprise) and the pros were Kudo Norio and Nakayama Noriyuki. My source was a post to rec.games.go by Bill Taylor.

After checking Google, the post may have been this one (but this is not how I remember it): [ext] http://groups.google.ca/groups?q=%22Bill+Taylor%22+7x7+group:rec.games.go&hl=en&lr=&ie=UTF-8&group=rec.games.go&selm=CGpsqI.rz%40cantua.canterbury.ac.nz&rnum=1

And Jasiek and Taylor have argued this point before: [ext] http://groups.google.ca/groups?q=%22Bill+Taylor%22+7x7+group:rec.games.go&hl=en&lr=&ie=UTF-8&group=rec.games.go&selm=7vggql%24iog%242%40cantuc.canterbury.ac.nz&rnum=6

There is also an article in the summer 1995 edition of the American Go Journal by James Davies.

JaredBeck: Can we assume by the score of 19-10 that komi on 7x7 should be 9? Or should it be 9.5? 8.5?

Evand: The correct komi for 7x7 would be 9 points, if the solution is correct. See komi for an explanation. The usual definition is that correct komi would lead to jigo with perfect play.


(Sebastian:) Interesting, that pushing the cart from behind (W10) can be best play.

Bill: Considering the fact that White is blocking Black from the corner, rather than trying to get in front, I think W10 is best described as a block.

DougRidgway: See this for another line and a link to the whole SGF.
