A “trained professional referee” should be very competent concerning understanding basic pool ball physics and how tangent lines work. This stuff is crucial to making correct calls confidently. After a careful video review, the correct call should have been figured out.
BTW, if any “good player” sets up this shot and shoots it both ways with the view Capito had, I am confident it would be very clear that the CB should not move the way it did if the hit were clean. The required hit on the 4 was very full. That CB should go forward, as demonstrated in my video.
dr-dave are you the best player in the world ever in the history of the universe and all the other universes? Do you know on every shot, as soon as you have hit the cue ball, exactly where all the balls are going?
Your analysis of the shot is great, and we can all learn a lot from it. Mostly, we can learn not to play that shot because, unless we play it correctly or almost correctly, the cueball won't
either hit the target ball first or hit both balls simultaneously. Good and honest players do this all the time to avoid controversy when they are playing less clued up opponents. But saying that the referee should have called a foul is stone cold wrong - it is not a clear and obvious foul. If I'm a TD and a referee starts making judgements based on what is "supposed to happen", I'm swapping places and asking that ref to follow my bracket.
