In [ext]The Theory & Practice of Go, Korschelt describes an experimental 21x21 goban that he constructed and turned over to his Master, Murase Shuho, for testing. Anyone who wants to try this can play email-style games on dragongoserver.net -- up to 25X25. Forrest Curo _

There are multiple possible definitions of what it means for a player to be the same strength on two different sized boards. It is impossible to pit a 9x9 player against a 19x19 player. If two people use different definitions of 'same strength', they are bound to disagree about which size people

Humans don't have much experience with 9x9 go. In such tight confines, there is a premium for precise reading; there is little margin for error. It is much harder to escape, and harder to trade territory for influence. There is also, as Dave Fotland observed, little established literature on the

2007/4/12, Don Dailey <[EMAIL PROTECTED]>: 9x9 is a good board size for computers. I'm not really sure if there is anything special about 19x19 (why not 17x17 or 21x21?) perhaps they thought 17x17 was too hard (if it's true that smaller boards are harder for humans.) To the question "why not
