Now I know why I am still a kyu player, I missed that obvious threat. It can't
be ignored.
It not only captures a lot of white stones, but resurrects black stones, which
leads to the death of a lot more white stones.
I can't see a white counterthreat big enough to match such a huge loss.
The error comes several moves back. More than once, white lost a liberty and
tenukied instead of taking a liberty from black. My hat is off to whoever
solves
this capturing-race issue for bots.

Many Faces takes the ko, but with only 24% win rate. It expects the ko threat
at F10, which can’t be ignored.

Yes, this is the one where bonobot resigned in (I believe) a clearly won
position. Take the ko, ignore one threat, play M12, ignore a 2nd "free move",
play L10 and take the L9 stones, finally respond to black's two free moves, and
I believe bonobot was still clearly ahead. Dan-level players seemed to be of
the
same opinion. In any event, it was certainly playable, not the best time to
resign.
I'd be interested if dan-level players read something different; I'm not in
that
league.
In any case, it looks like a great program! I wish you every success in
repairing these flaws and making still more progress.
I'm also interested in seeing how well bonobot does with longer time settings.
