Though these are not mutually exclusive, of course. \n\nHandicap is automatic, because the goal is to give everyone a fighting chance. Please make sure at the beginning of the game that the handicap is somewhat appropriate (I think it only takes correspondence rank into account). If it is not, the advantaged player is invited to pass as many times as necessary to establish balance. \n\nSince this is a learning group, reviews are encouraged.\n\nHave fun!",
