It has discussed in length a few times, but you'll find on these rules questions there is no conclusion. If a poll was taken then we would have a result. But there again OnePocket.org does not play by this rule, so it has little importance!
It could become of importance if OnePocket.org was to compile a host of alternative rules that the game could be played by. I think this is important for why should OnePocket.org be late to the party, instead of leading the way in the category of alternative rules. We do have some existing alternative rules written in the Official OP Rules, but I am referring to a complete separate listing.
DCC plays by this rule of if you score on the break it is a re-rack, but if you go under their DCC alternative OP Rules there is no mention of this scenario.
Therefore by Official OP rules, when the cue ball pocket scratches the opponent receives BIH. The scored ball is spotted and the player is assessed a foul. This IMO is the best way to play out this scenario if you want to stay on track with traditional OP. Whitey
