Rolling-Cue-Ball CAROM ANGLE Systems

Dr. Dave demonstrates several useful systems to accurately predict carom direction for rolling-CB shots. The carom angle is the amount the CB deflects off the OB. Being able to predict this is useful to detect a possible scratch, to plan break-out and carom shots, and to visualize position-play paths through “traffic.”

CORRECTIONS:
- At the 3m07s point, the line showing the predicted CB direction should have gone from the finger to the 1 ball.
- In the diagram at the 3m46s point, ​the 0.281 and 2/7 (0.286) lines were mislabeled. They should be switched. 1/4 (0.250) is less than 0.281, which is less than 2/7 (0.286).

It's totally amazing to see so much thought, effort and calculation going into these systems.
But even more amazing is that you explain it to us "normal-thinking" people like : 'just learn how to wide to spread your fingers'
Truly effective teaching, especially when you're on the shot-clock.
Great video!

[battlefieldclips]

I’m a simple guy, sees Dr. Dave’s video, like it first n then watch it later !!!

[jonathangorman]

I've been looking for this exact video for a while. Makes me feel better that despite my best efforts, I've been struggling to figure out carom angles. I'd argue this is one of the most important things to get down. I've blown easy run outs so many times. I learned how speed and English change caroms a long time ago, but didn't know what the natural carom is!!!

[andraskoleszar]

I wish I didn't have to resort to my big word dictionary, but this is the most COMPREHENSIVE video on rolling cueball motion that I have ever seen. Purely amazing. The standard was hard to beat, but you truly outdid yourself with this Doc! Thank you for sharing❤️

[jaroslavcech]

Thanks Doc! You never stop to amaze me with your scientific approach. This is just insane amount of great information in one video! Thank you from the bottom of my heart for what you're doing for the world pool community. This is just amazing! Best of luck

[captainhundred]

I have found that playing reverse pool helps very much in caroms and scratch prediction. We play where any ball off the cue pocketed is 1 point. 10 points win, scratch erases score.

"If your peace sign is well calibrated"... lol, love it!

[jerryhughes]

Thanks Dr-Dave. You really do aim to swerve!

[chscythe]

Thank u for your tips and guide dr. Dave love you from the Phillipines🇵🇭

[martinandredill]

Wow, this is pure math, thanks for this awesome techniques. This Channel is perfect.

[kimsoriano]

thats why im always watching ur videos because i learned alot..thanks..

[brianhiles]

This is masterful. This video, with its mathematics, techniques, and rules-of-thumb, addresses the ongoing question of the relative efficacy of the HAMB method (Hit A Million Balls) and systemic analysis.

Only 14, 000 views!? This video should be in some kind of billiards canon for those serious about learning _why_ things happen the way they do.

I have only one quibble: _Carom_ has a specific meaning in billiards. (I am also aware of the _game_ of Carom on a Carom table). Perhaps the term _rebound_ instead?

*P.S.:* Generally, I´ve seen the other videos for which this one is a condensed overview plus new ideas. I´d like to specifically acknowledge the time and effort it must take you to annotate the many references you include in the description (and on your website), plus the up-to-date errata, for this and many other of your videos.

I wish I had the money to purchase your entire DVD set. (It´s a bad time).

[vincentbeaurivage]

I LOVE and ADMIRE your work, but if I play against a slow player who starts to measure his rolling angle with this method during a game, I might lose my calmness! Great work and amazing vulgarisation again! Thanks Dr. !!!

[jancollard]

Good afternoon to you Dr. Dave
My local women's league was wondering if you know any time shots that you could show us the set up just for fun. We already know the one with the cue ball and the eight kissing on the long rail and you bank the cueball and it moves the eight in front of the side pocket to be hit in by the cue ball.

But we were thinking if anyone knows some time shots it would have to be you! We have looked all over YouTube and the internet and we cannot find any information on them. We want to learn a handful for the challenge and of course for fun. Any help you can give us would sure be appreciated. Thank you so much Dr. Dave we love you. ❤️

Amazon wish list after viewing this video: Master chalk, slide rule, protractor, 8, 000 hole reinforcements, graphing calculator, Magic Rack, tape measure, and vodka.

Two questions not video related:
Why do you use balance rite other than needing few extra inches, does it give any advantage?

What happens when using this mid extensions on a uni lock and mating it to another uni loc, this only means you have two uni locs in your system cue, people complain about one uni loc thinking that it’s scary, how do you feel about having two ? Isn’t it bad?

[deathshead]

Great video. I play British pool though, where the cue ball is slightly smaller and also lighter than the OB. Does this have any effect on the angle?

[lgold]

Hi Dave. I’m not sure how I found you / do you list your videos as gaming or sports on YouTube

Dr Dave
Can you show some basic 1 cushion and 3 cushion players techniques to improve pocket billards players?
Thanks in advance✌️
