That would be a useful chart to have during matches.
You might be best off just making your own. There are only a few possibilities. Someone please correct me if I'm wrong:
Both balls out of the rack - leave them where they lie
Both balls in the rack - rack 15 balls, CB behind the string
CB in the rack - leave the OB, CB behind the string
OB in the rack - leave the CB, OB on the head spot
OB in the rack AND CB obscuring the head spot - leave the CB, OB on the center spot
14th and 15th balls pocketed during the same shot, CB out of the rack - leave the CB, rack 15 balls
14th and 15th balls pocketed during the same shot, CB in the rack - rack 15 balls, CB behind the string
Did I miss any?
