As a TO I always put myself (or a helper) down as a Spare player, so if an odd number turns up, I play, and if an even number turns up, then I don't.
I think most TOs do this.
what we tried to do if even, is to do this way:
- having several spare players. (ideally 3, for a one-dayer tourney)
- each of this 3 players is off one round
else, what happens most of the time, is the following, one or several coachs of our local league are not allowed (by wife) to be there all day , and came for one game or 2 (most of the time, with a funny roster, like gobelins, in order)
so "à la carte", but every heres came for just playing games and meet coachs, to the more participants, the better
