Suicide? Do you mean self-atari? But there must be more to it than that
because you don't have a rule that prevents all self-atari, right?

X can't fill J6 because that would be suicide. For the moment, H5 is an
eye.

Subject: [computer-go] Complicated seki with Ko
With X to move, Many Faces immediately gives about a 1% win rate, and
after
a few seconds, resigns, showing 23742 playouts with 0.5% win rate. 10
ply
principal variation, staring with A7. I don't have any special code to
detect superko or give-2, get-1 in playouts, but the playouts don't
generate
self- atari moves in a seki, so I think it never tries J6 for either
side.
How does MF recognize that it is a seki without analyzing what happens in
the ko?
The eye on H5 is false if X can fill J6, so it is premature to use the
"both
sides have an eye with only shared liberties" rule.
