Knockout is probably the best way given we're in a situation where scheduling will probably be an issue. I'd say the games is dependent on how fast it is. Most of the time 1 game is sufficient for casual things. My personal preference is for 1 0 or 0 1 games online, but something in the 10/0 or 30/0 range is probably the most agreeable time to a more casual crowd. Or are we forgoing timekeeping entirely?What kind of rules we thinking?
Swiss or knockout?
1 game or best of 3?
