I agree, that was clearly a foul and should have ended his run. If he'd beaten Mosconi's 526, it would have eventually been completely discredited by this foul. I often practice 14.1 late at night by myself, always with the thought in mind of challenging my all time high run. Even though I don't video it, if I was to commit any sort of a foul like this in which a ball moves, I automatically start my run over, regardless of the fact that I'm alone in here, nobody is watching, and I'm not video taping the run. Anything less is cheating yourself and your own integrity, particularly as a 14.1 player - one of the few games left that is viewed as a "gentleman's game".
