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!
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
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!!!
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❤️
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.
@@battlefieldclips7013 There are different versions, but the simplest is: On every shot, strike any OB off the CB to try to pocket the OB. This is covered, with other ways to practice caroms, on VEPP-IV: drdavebilliards.com/videos/vepp/disc-IV/
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).
@@DrDaveBilliards Have you ever thought about playing live games with guests? or making live videos answering questions from your fans .. It Will be incredible, this is working very well here in Brazil and the players here dont have half of your technique.
@@martinandredill I like the idea of doing some live videos where I answer questions. I've just added this to my list. Thanks. I'll be sure to announce them on Facebook and to my RU-vid subscribers.
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. !!!
I agree that some of the techniques in this video are not fast, especially if you have not practiced them a lot. However, the peace-sign stuff is very fast, easy, and accurate with just a little practice.
@@DrDaveBilliards - More than anything, I think using these techniques to get precise carom angles during practice will help visual memorization so that it becomes more natural. This way, you don't have to be that person during a league match who's doing crazy stuff with the cue, haha.
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 RU-vid 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. ❤️
Sorry, but I don't have any resources for timing shots, other than the one you mentioned and "wing shots." See: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gDWU4WwM19o.html
@@JustCallMeLoathesome That's a bit excessive. :) All you really need is this: billiards.colostate.edu/resource_files/30-degree-rule_angle_templates.pdf
FYI, I posted lots of "vintage Dr. Dave" pool and super-slow-motion videos 14 years ago, even before the high-voltage arc video. See: ru-vid.comvideos?view=0&sort=da&flow=grid
this is way awesome, dave - your youtube videos (and the full series discs too!) are just amazing, thank you! question: is it legal in tournament play to have a reference marking on your cue? -todd
Have you ever tried just aiming at the spot on the ball that points towards the direction you want to go? I will try to explain better, in the beginning of your video you use the 13 ball and the one ball so I will use those to explain. If you draw a line through the center of the 13 ball directly to the 1 ball, there is a point where that line meets the back of the 13 ball. I have found that shooting the cue ball towards that spot is an excellent approximation of what you are explaining. Obviously you can never hit that point because it is on the opposite side of the ball you are shooting at.
That's called "back of the ball" aiming. I have tried it. I've also analyzed it. For more info, see: billiards.colostate.edu/faq/cue-ball-control/where-cb-goes/#full-thin
I already have lots of stuff that is helpful for carom/billiard players. Check out the CB control stuff here: billiards.colostate.edu/faq/cue-ball-control/ and the kicking system stuff here: billiards.colostate.edu/faq/bank-kick/ That should keep you busy for a while.
Dave, here's one you have to see if you haven't...this cue ball is amazing, Judd Trump, snooker, about a week ago: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OOMipTXxhoY.html Good stuff here, if I ever get back to a table. You could also put marks on your cue with a sharpie if you wished. They will come off the finished portion with alcohol...not sure how well they would come off an unfinished shaft, though. Maybe very thin pencil or pen lines would work. I was going to build a stick and was thinking about working a lot of the rules of thumb into the design, you could easily hide many of them, if it mattered, in diamond angles chosen, etc. I don't think I've ever seen rules prohibiting this though. I should look it up. If you don't mind throwing a snooker shot into your replicate awesome shots series, this might be a cool one to add. Mr Barton said he found it very difficult to emulate. I don't know if it'd be easier or harder on a smaller pool table with different cloth, though.
I have seen it. I actually have a link to it here: billiards.colostate.edu/videos/snooker/ I think it would work on a pool table, but the cloth would need to be very slick and fast. If I do another Top 10 Famous Shots video, I will definitely include this shot. FYI, my other videos in the series are here: ru-vid.com/group/PLH9d4KFY28XscHllvlP_rVC1jQjDXZmYD
It is fine. I got it only to increase the length of my cue since I am tall. I've also grown to like the added weight; although, I over-hit everything at first.
I would recommend ignoring everything except the peace-sign stuff. That technique is easy, fast, and accurate with a little practice. For more info, see the videos and info here: billiards.colostate.edu/faq/30-90-rules/peace-sign/
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?
I don't understand the concern about Uni-Locks. I don't have any problem with them. Concerning my joint extender, I have it only for the added length. I also grew to like the extra weight. But I don't think there is any real advantage beyond that. See: billiards.colostate.edu/faq/cue/balance/ and: billiards.colostate.edu/faq/cue/length/ Enjoy!
@@DrDaveBilliards I don’t have problems with uni loc but I was wondering that you got these piece cue how can it not affect anything? So you’re saying that if you have one piece cue or a cue that is cut by 10 sections with a pin in each section, regardless which pin if it’s uni loc or radial or whatever, will both cues play the same? Please try to not just paste links and answer with words maybe 🤔
@@xanh350 Additional joints can affect the feel and sound of the hit and the cue weight; and if there were any joints close to the tip (within 6-8 inches), you would have a real problem with CB deflection, but that's about it, assuming the joints are all tight as they should be. I actually check my joint tightness periodically when I am playing, out of habit, just to be sure. For more info, see: billiards.colostate.edu/faq/cue/feel/ and: billiards.colostate.edu/faq/squirt/endmass
I don't use the cue pivot tricks, but I do use my peace sign frequently in matches (especially when the exact CB direction is critical). It is fast and it works like a charm.
Also, some things in my videos are just curiosities or principles that people find interesting (and sometimes useful, or sometimes a just as a tool to help learn and develop intuition for something). Not everything is meant to be used literally in game situations.
... from electricity physics to pool physics ... a good redirection. :) For those interested, here is the mentioned high-voltage arc video, which has been getting lots of views lately: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GMbN9nb3qyk.html
The cue methods are honestly not very practical (I presented them mostly for people who have an interest in pool technology and info like this), but the peace-sign trick is very useful.
The peace sign is easy and effective. Alternatively, just play long enough so you can intuitively “see” the natural angle. Ain’t nobody got time for that! :)
