In game Ranked, 9x9, there are three places where AI has determined a really bad move. These are typically shown as “-79” in a circle.
I think this must be a software error. It should show as “-7.9”, no?
I have also seen cases where “-79” is meant not to have a decimal point, because a player didn’t notice that a very large group had just a few liberties, and it was captured. When there are 40 stones in the group, capturing it could give 80 points, right? At least in Japanese rules, the only ones I barely understand.
I do apologize for suggesting that OGS might have a bug. I’m probably just not understanding something.
