At a guess, perhaps the "before resignation" equity should be -2.3?

After a closer look, things are clearer. If the dice haven't been shaken, the position is evaluated (from the current players perspective). If the dice have been shaken the best (0-ply) move is made and then the position evaluated (from the other players perspective).

Clearly the code above in my previous email only applies if the dice haven't been rolled a different calculation is needed for the case with the dice rolled.
