I went back and I took another look through your logs and configs, but I still don't think I know how to help, sorry. It still just looks to me...

Yep, there are many dozens of other known and recorded situations where the net makes a mistake too, the same way that top human pros sometimes simply miss a move....

This is great, thanks. There are a few things I'm interested in testing to help the search, and this seems like a good example position to try it on.

Thanks for this example too! I can add it as well.

Thanks, do you have an SGF for this second case?

The case that you posted on July 11 it turns out was never added for training. I can add it now though.

You probably configured KataGo to use the wrong rules. Check CGOS's documentation for what its rules are, then specify those rules in KataGo's config.

No, I remember from before CGOS's rule is not tromp-taylor, it's something else. Please check the documentation for CGOS carefully.

Seems like you should use neither one. Since CGOS uses neither Chinese rules nor Tromp-Taylor rules, but instead uses an alternative version of Tromp Taylor rules where suicide is prohibited,...

Take a look at this section in the config. https://github.com/lightvector/KataGo/blob/master/cpp/configs/gtp_example.cfg#L94-L115
