There is already an Estimate Points button in the gamereview after each finished game you’ve played. I would like to have this “estimate points” function in other places as well.
Of that I am aware.
Read again: I wrote that I am not aware that KataGo has PARTIAL SE.
Maybe you can try and inspire some of those who actually develop Go AIs if you do not intend to DIY?
I have trouble understanding what Andreas means by a “breakpoint” (to me it is a point in a programme where execution is stopped to allow the developer to investigate its behaviour). But anyway, Benjamin Teuber’s site AI Sensei does a a good job of creating problems from your games, which may help some people interested in Andreas’ idea, even if the approach is not what Andreas intends.
