3-on-3 rules

[Jim O'Connell]

I currently run a 5-on05 adult basketball league, I'll be starting a 3-on-3 league in the spring. I am looking for a set of rules for 3-on-3. I realize that most rules would be the same but there may be some critical differences. For example, should it be a half-court game or should we play full court on a smaller court. If we play half court, should we play alternating possessions or make it-take it. And, will I be able to get by with a single ref for these games, or will I still need two like in my 5-on-5 league. I realize that many of these issues may be a matter of my own preference instead of actual rules, but I am looking for guidance on what has worked for others. Thanks for your help.
