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 Aa
