I composed this related problem:

$ gq -l games/trevor/trevor_35.sgf  --decide-dragon J10 -o t350.sgf
finished examine_position
J10 can be attacked at L10 (5 variations)
J10 cannot be defended (3 variations)

Clearly L8 will lead to a Ko.  However, I have no idea of the best
way to fix this problem.  Seems like an optics ko problem, right?
Can simple tuning hope to help it?

See related simple problem:

loadsgf games/trevor/trevor_36.sgf
360 owl_defend G8
#? [(2|3) J9]*
