Subject: Re: [Computer-go] Komi and the value of the first move

I couldn't find the article again where I read that 20 - 30 points was an accepted value for the first move.

If you mean 19x19 and the first move is played in the corner, then its value is around 10 points.

I think it's closer to 14 points.

Actually I agree to Nick, it's maybe around 10-15 points. 10 points is a very general and traditional view among high dan and professional players. I was not mean to give an exact value, but to argue that over 20 points is just too large for a move in the corner.

This page contains some information (maybe you have already read) that supports my traditional view:
http://senseis.xmp.net/?Komi

[7] Bill: Which pros? The traditional value is 10 pts., and the first Environmental go game? revealed that Jiang Jujo and Rui Naiwei did not agree on the value of the first move. Rather, it seems that the value of the play is inferred by mathematically inclined amateurs to be two times komi.

I believe that an opening move on, say, a 4-4 point is worth about 14 points. An opening move on a 4-10 or a 10-10 point may be worth slightly less (though I have seen no convincing evidence of this), but still more than 10 points.

Yes, it is maybe not a correct estimation. I also agree to Stefan that komi and the value of the first move are more or less different concepts. But anyway, by far no one can say for sure the exact values, since we don't know at all what is the optimal playing of Go. Even professional players make many mistakes while playing.
