Re: [pbmserv] Bug (?) in Zertz game

No, only if one or more isolated rings are completely occupied by marbles,
the active player captures the marbles and the rings are removed from play.
In the above situation the isolated ring is empty (therefore it isn't
removed), so player2 can just put a marble on it and capture this marble,
but she will loose the initiative after that.
