Congrats to Zen this time. Thanks again, Ingo. Later this group went over Jordan. For some reason crossing the Jordan is not one of the hundreds of euphemisms that do exist in the english language. How about it entered the garden of serenity :-) The MFs winrate graph is pretty good at telling

I'll admit, I'm not a dan player. I don't even play enough to know my rank. Probably I'm missing something about the position. But it seems that the group simply doesn't have two eyes and allows Zen to remove the last way of getting two eyes. Although Zen also did not see it as being as

Ingo is correct. The territory chart's fluctuations are because it uses the old territory evaluation without any lookahead. So for example if a move threatens a big group, and the reply saves it, there will be fluctuation, since the group's territory went from solid to unsettled, back to solid.
