There are two basically different handicap systems, right? One of them allows free placement of the handicap stones and the other is fixed. I would probably do the fixed version for consistency. To accommodate programs that haven't implemented handicps I could just send play commands along

I'd really like to see a way to work out the issue of handicap stones so that they can enter into computer go competitions. In the past, there's been strong complaints about stronger bots playing against weaker bots. Would giving handicap make such match ups at least seem more interesting? I thi

I would like to take part in the 19x19 competition. I also prefer kyu rating to Elo, but I got the impression that you were relating kyu rating with handicap games (that is usually done by human players). I think handicap is a bad idea for computers. Handicap requires human intelligence to unders

I think probably I just go with ELO, much simpler. I think later we will want to have handicaps.Even at 9x9 Mogo is all by itself although I expect other programs to eventually catch up or get close later. For the Anchor, I think I will take David suggestion and start with AnchorMan. The

Hi Sylvain, I'm not worried about the ELO situation but you are right. When skill is measured by ELO you are talking about the probability of winning a game against any given opponent, we just have to be careful how we interpret or compare to other board sizes. If 2 opponents are 50 ELO rating p
