The handicap system is imperfect anyway, it's almost a coincidence that it works as well as it does. okay, this sounds like chess bias. the handicap system *defines* the difference in skill levels in go. it's a coincidence that something like ELO can match fairly well to stones. not the

Pro ranks are assumed to be about 1/3 of a stone; the one stone per rank formula applies to amateur ranks. I have watched a pro 8p regularly give three stones to a 6 dan amateur. A weaker pro might give the same player 2 stones. Some ( including myself in the past ) have argued that they can

I can't really agree with this statement. My customers tell me they would much rather play a challenging even game against an opponent of their level, than a challenging handicap game against a much stronger or much weaker opponent. This is why version 12 of Many Faces has levels that are

At 1 or 2 stones difference, the handicap system works well.At greater handicaps it's skewed. The coincidence that I'm talking about is that it works to a reasonable degree at larger handicaps. The handicap system is based on the idea that no matter what your level of play, you

I am 3k on KGS and I'd say that I win nearly every game that I give handicap and lose over half the games that I receive handicap. That would seem to imply that more handicap should be given near my rank. That is because the KGS rating system is not based on handicap. It is

The purpose of a handicap games is to allow a 50% chance of either contestant winning. .. Programs do not care, Are you sure?-) I haven't got round to moving beyond a plain MC bot yet, where the effect is rather striking, but less naive bots also depend on win-rate for their move evaluations.
