Although Tei and Aoba Professionals explained the match at the front stage with a projection, the game was so complicated that I couldn't see which is winning until near the end. Another semi-final match, my Fudo Go vs Katsunari, also was shown on the screen but in a small picture at upper right

What you are saying is that many professionals are overrated or underrated (sometimes by as much as two stones). The same goes for amateur ranks too. So a rank estimate from a series of 7 stone games against a 4p will still have a error margin of one or perhaps two stones. I agree with that.

I think a 7 stone handicap against a 4p would be normal for an EGF 1d, not for a japanese 1d. A japanese 1d is about 3k EGF. He would require more than 9 stones. Dave Van: computer-go-boun...@computer-go.org namens Darren Cook Verzonden: wo 17-12-2008 2:48

When the japanese audience stated that CrazyStone was playing like a 4d or 5d they were talking about japanese ranks. This suggests that it played like a 1d EGF or 2d EGF according to the audience. Dave Van: computer-go-boun...@computer-go.org namens

One of my customers tried a tournament between Many Faces and Go++ 7.0, one of the strongest traditional programs. He says: Good news first: after 30 games MFGo12 (32min) vs. Go++7.0 (level 5) your program showed to be much stronger even on my slow PC - result so far would be 22 - 8 ! David

Hi Mark, I'm not claiming to be an authority on the matter, but I beg to differ. Name me an EGF 7-dan that's not professional level. And then explain how come they are listed among players that are anywhere from 1p to 5p in different Asian countries. I used to be an EGF 6-dan and have beaten

One option is to reduce the time limit from 40 minutes to 30 minutes to add another round. You can seed a swiss competition so it is likely that the best programs will meet in the last round. Regards, David -Original Message- From: computer-go-boun...@computer-go.org
