Jouni, 6d’s are NOT ridiculously strong. I am a solid 6d KGS player but lost many games to Zen and Crazy Stones. Actually they might be able to reach 6d already with 10 secs/move or in even faster games.

Also 6 months is very very short time, and when old games are starting to expire, KGS rating will follow. See e.g. CS rating graph for reference. KGS rating system works brilliantly and it is almost impossible to exploit, because only way to exploit it is to make 8d? account and then go kibitzing other people's games, but if there are only few games played, it has very little influence for system as a whole. Therefore it is certainly better rating system than in any other Chess and Go servers. (it is even better than Glicko) People observe KGS-rating system often problematic, because it punishes most severely those who are weak players. one improvement to rating system could be, that it would calculate separate ratings for both, slow and blitz games. 6d for MC-gobot seems a bit optimistic, I would bet €5 that it won't happen in 2012. 6d's are ridiculously strong. I calculated that in January, out of 56 games against 5d's CS won 48%. This is indeed impressive, although there is long way to beat 6d's in even game. –Jouni On 7 January 2012 21:03, Jeff Nowakowski <[email protected]> wrote: On 01/02/2012 05:04 PM, Rémi Coulom wrote: Improving the KGS rank at 5d is very difficult. The current experimental version of Crazy Stone wins 78% against Crazy Stone 2011. That's less than one stone difference on KGS. But I am sure both Zen and Crazy Stone will reach 6d in 2012. There are two problems with the KGS rankings: One, they are weighed down a lot by past games from weaker versions. Two, you have to worry about people trying to game the system. I found strong evidence that one of the frequent CrazyStone players was losing games intentionally against a weaker bot, while at the same time winning frequently against CrazyStone. I brought this up with an admin, and he said they were looking into it, but several days have gone by and the player was not deranked (which is the usual punishment for gaming the system, and would remove past games from the rank calculation). -------------------------------------------------------------------------------- _______________________________________________ Computer-go mailing list [email protected] http://dvandva.org/cgi-bin/mailman/listinfo/computer-go
