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 are better at.
Off the top of my head, 'same strength'could be defined as i) Same amount of experience of both games, ii) Drops the same number of points over the course of the game when playing a perfect player, iii) As ii), but scaled for the board area, iv) Typically reads the same number of moves, v) Same win rate on average when playing typical human players, vi) Same win rate on average when playing Gnu Go.

David, I saw this on Sensei's Library that indicates larger boards are harder: ----[ snip ]---- 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. He describes a sample game that was played out to about 130 moves before ending. Only the first 57 were shown. Korschelt remarked that the game "took on a freer and more deeply involved character, but ... at the same time the difficulty of keeping command of the game grew at an extraordinary rate." He goes on to note that on a 19x19 board, "too many unexpected situations turn up for beginners," and speculates that if the board were to increase to 23x23, "not even the best players could any longer maintain a comprehensive view of the countless possible combinations." ----[ snip ]---- This seems to also match my intuition, even though I'm not as good a player as you are. If you extrapolate backwards, to 7x7, 5x5, 3x3 it seems clear that smaller boards are less complex and therefore easier to master. I cannot believe 9x9 is harder than 19x19 and I don't care how strong the player is who says that - I don't believe it. - Don _______________________________________________ computer-go mailing list [EMAIL PROTECTED] http://www.computer-go.org/mailman/listinfo/computer-go/ -- This email has been verified as Virus free Virus Protection and more available at http://www.plus.net
