this is the way to interpret the situationHere are my two thoughts on this topic. I have played thousands of games of one pocket over the years, and this scenario has never happened to me. #2. If it's true that when you accidentally touch the cue ball when you have ball in hand behind the line, that your opponent will then have ball in hand, well that is a stupid rule and should be changed. Because there is no other scenario in one pocket other than a cue ball scratching that gives your opponent ball in hand, and this should be no exception. So the good part is that this type of scenario is super rare, and like any other game of pool, you and your opponent can agree to some common sense rules.
the onepocket,org rules say this(bolded parts by me for emphasis)
6.3 Cue ball after a foul: Following either a pocket scratch or the cue ball jumping the table, the incoming player has cue ball in hand. Following any other standard foul, the cue ball is played where it lies.
and this
Unless clearly contradicted below, general pocket billiards rules of play and conduct apply to One Pocket, and complete General Rules & Regulations are available from the World Pool-Billiard Association (WPA) or the Billiard Congress of America.

the rule 6.3 clearly contradicts the straight pool rule and would/should be the rule followed in a onepocket match
@Bob Jewett agree?
