is a correct double/beaver even without Jacobyrule if the table stakes are set to 8 times the initial stakes (it is on snowie 3ply)!? But of course using a met makes gnubg work in match mode so beavers are not allowed. Is there a way to allow for beavers even in a match? If not, how can I deduce from the results of the rollout if a beaver would be correct?
