Hello, I informed the German go scene that there is (some) progress at KGS bots with dynamic komi. Based on this, a friend told me that they would have an open afternoon for go beginners in the middle of March - and they expect many newbies with strengths between 17k and 30k. His question is if a

Fuego_9x9_1h (or a variation of this name) played on OGS a couple of handicap 9x9 games. It used dynamic komi. I think it was manually adjusted after every move, and worked well. -ibd Am 17.02.2010 um 22:51 schrieb Ingo Althöfer: Hello, I informed the German go scene that there is (some)

Does anyone have data based on several thousands games that attempts to measure the effect of dynamic komi?I would like to see results that are statistically meaningful. We need to see a few thousand games played against a fixed opponent WITH dynamic komi, and then the same program without
