What you say is consistent with what I've heard from other sources. My understanding is that in ELO terms the ranks are compressed at the higher levels and spread out at lower levels. So there is less difference between 4 dan and 5 dan than 15 kyu and 16 kyu for instance. If I want to use ELO and also expect the handicaps to be fair, then I will need to account for this curve. On the web I see that some ELO based GO servers assume 100 ELO is 1 rank, and do exactly what I proposed, when they handicap they fold this into the ELO rating of the players for rating purposes. I would like to do better than that, so what I need is a formula that can be gradually adjusted by the server. Something more sophisticated than just an ELO to stones formula that takes more into consideration than just the rating difference. I'm glad you brought this to my attention. - Don > David > > > -----Original Message----- > > From: [EMAIL PROTECTED] > > [mailto:[EMAIL PROTECTED] On Behalf Of Don Dailey > > Sent: Friday, December 22, 2006 2:04 PM > > To: computer-go > > Subject: Re: [computer-go] Anchor Player > > > > > > So really, what I want to be able to do is: > > > > 1.
