The resignation is evaluated at 0ply, which is not perfect. in the attached game it thinks player 1 loses 0.02% gammons.

Evaluating it at 2ply would do the right thing here (but it is not perfect either and could miss other cases, although surely many less than 0ply).

I think the choice of 0ply is from when CPUs were much slower and the idea was to avoid causing a delay when the user wants to finish the game quickly. Nowadays 2ply would probably be fast enough, or we could do something like : 0ply, if accept, we're done, if not reevaluate at deeper ply.

On my turn, when any roll will allow me to bear off at least one man (and then lose), my offer to resign (normal) should be accepted but is declined.
