This is the side view and is how a ref. would position theirself to view the contact point. With draw the cb is not allowed to go past the contact point.

https://drive.google.com/file/d/1ZbNG3z88AJnQSJZVSsKhoFy7hAPX0gem/view?usp=drivesdk This is a follow shot, the cb must hesitate at the contact point before going forward. If the cb takes off at nearly or the same speed as the ob, you know it is a foul. I wish I would of hit this just a little better, but I had a really good slow motion side view, whereas the cb sat there and spins before going forward, but I lost it.

Here is a couple of my favorite shots.

But, I am slightly cutting the ob and thus the cb initially goes on the tangent line before the spin takes over. It the cb went forward through the tangent line then it would be a foul.

on the internet, if you type in Pool Rule Quiz, and then go to answers, shots like these are on there. Many players think that if they elevate the cue then a foul would not happen, or not called, not so, for the same foul criteria applies providing the cb is not jumped into the ob. The Quiz is done by Bob J. and very well done.
I thought by posting these videos it might complement the rule Steve posted for discussin. Enjoy, Whitey
