straightline: "Can you provide the logic behind this?"

I wanted you or PJ or Bill to post a video demonstrating your point of view on the subject.

It's all about "throw" - if you understand it our "views" are simple cause and effect.

A refresher:
When the CB's surface rubs across the OB's surface, either from the CB hitting the OB at an angle ("cut-induced" throw) or from CB side spin ("spin-induced" throw), or a combination of the two, it creates rubbing friction that "throws" the OB a little off the CB-OB line-of-centers (more on straighter and slower shots). Throw must be compensated for while aiming, either consciously or "by feel".

"Cut-induced" throw can be easily seen by freezing two OBs together against a rail and shooting that "dead" corner pocket combo straight into either OB from an angle (as if it's the "ghost ball"). You'll see that maximum throw does indeed happen at about a 30° (half ball) cut as shown by Bob's chart above.

A Catalog of Common SCRATCHES, and How to Avoid Them

So in the shot I referenced how do you teach your students to not find the bottom of the side pocket?

I start from the path the cue ball wants to follow with it rolling smoothly on the cloth and no sidespin. If that leads to a pocket or anywhere else they don't want to be, then the shot has to be modified. In the case of the scratch shot at 10:35 in the original video, there are many ways to avoid the scratch. Which way you choose depends on where you would rather go. If you don't want to use side spin, hitting lower on the cue ball to get less than full follow when it arrives at the object ball is the only choice. Well, you could hit it so hard the follow action is delayed, but that would cause other problems.

I think a good way to learn the paths of the cue ball from full draw to full follow for various cut angles is the Wagon Wheel referenced above. Those paths can also be used for the shots along the rail in the video.

That would be great if there's enough players for a short tourney.

There's not much chance of success 4 a 3C tourney with this format, except within certain select areas.

There used to be a single elimination handicapped weekly tournament at Bob Byrne's home room in Novato. I think Diab went to 20 or so. Played on three tables.

Gomez comes back from the brink of disaster to claim International One-Pocket Open

azhousepro
St. Augustine, FL – At what proved to be (at the time) the most critical juncture in the final match of the $20,000-added International One Pocket Open (with others to come), Justin Hall was ‘on the hill’ at 2-0 in games, and ahead in balls in the third rack 7-4. It wasn’t the first time in the game that he was one shot away from the title and wouldn’t be the last. He bent down to shoot the ball that would finish the match; straight-forward, medium-range shot, straight into a corner pocket. And missed it, the ball hitting the short […]
