I wish I could like this video more than once. I had to discover a bunch of those shots the hard way. I'm glad to see them explained within the framework of CIT and SIT. Thank you!
Yesterday, (Sunday) I was going to post a comment on an older CIT video of yours to ask if you have any new videos on throw, specifically stunning balls into centre pocket. Then today, I see this little gem. Its like you read my mind. Thanks so much posting these great videos. I really appreciate the time and dedication it take to do this. I can't wait to share with the team!
Thanks to your previous videos on throw, I now came up with a trick shot that I show my buddies occasionally. The shot seems impossible because how the two balls are wired, but you are able to throw the second ball length of the table bank. Very beautiful shot on my nine foot table. Thanks again Dave for the tips!🙏🎱🙏
i always underestimate CIT for sharp cuts, i think "more spin and more speed = more throw" but it makes sense why that isn't always the case. also the part about frozen rail cuts goes against everything i thought i knew, but i haven't been consistently making them lately and now i may know why lol. thanks doc
Hi Dr.Dave, at 3:13 you said that to make the rail shot we need to have CB touch the rail slightly before the OB, and the CB cuts the OB away from cushion to cancel the throw. My question is, what throw, and why does the CB cuts the OB away from cushion? Do you mean that the CB's cut cancels the OB's SIT due to CB's spin picked up from rubbing the cushion? Or do you mean that the CB actually cuts the OB into the cushion, but because it is boucing away from the cushion, the CIT on OB is away from the cushion, and these two cancel?
It can work both ways. If the CB is still compressing the cushion at OB impact, the cut away from the rail (due to the compression) cancels the CIT. If the CB is already rebounding from the cushion with transferred sidespin (but the cushion is still compressed), the SIT cancels the cut. For more info, see: billiards.colostate.edu/faq/rail-cut/aiming/
@@leopard24 Sorry, but I made this one as simple as I could while still keeping it useful. Try watching it again (or several times). Better yet, try each of the shots at a table, one at a time.
Btw, with the extreme cut example notice how the check side spin kept cue ball in place, it was very firm stroke and yet the cb only traveled two cushions. This is very useful in any thin cuts when you don’t want the cb to fly around the table (eg 9ball or 8 ball last shots)
A lot of people don't believe in SIT, but I have been using it for 20 years. People told me I was wrong to my face, but here we are. If you are using spin, then you are throwing the ball and your CTE aiming system is garbage. Dr. Dave finally putting it to rest.
CTE has worked for me and improved my shot making since switching to it. I don’t use it with all shots but most. To say it’s garbage is funny to me. And how do people not know how putting spin on the cue ball affects the throw and path of the object ball?
@ CTE does not have throw correction built in, but this is the case with any “aiming system.” I personally think a better approach to aiming is DAM: billiards.colostate.edu/faq/aiming/dam/ I’m not sure what the other person meant by me putting CTE to rest. Maybe he was referring to my evaluation and analysis here: billiards.colostate.edu/faq/aiming/CTE/evaluation/
@@scruffyleon7383 I'm glad to here it. If you want to learn even more about throw, see items 16-40 and the supporting links and videos here: billiards.colostate.edu/faq/sidespin/aim/effects/#list Enjoy!
There's one question that comes to mind - what path do the balls actually take? A pretty straight line from the starter position at an adjusted angle? Or do they bend slightly on the route? I've heard it explained in terms of the balls basically skidding forwards as a pair before the object balls is released. Does it make sense to visualise as if the balls were slightly further forward and then picture the true mathematical angle from that position? Rather than to just think of finding the angle and then aiming thinner? I'm not sure whether picturing the balls further forward is the closest thing to the literal explanation, or whether it's a good idea to think this way (even if not necessarily quite real). It seemed to help to picture that skid forward rather than just to aim thinner.
@@cziffra1980 The balls stay in contact an imperceptible amount of time. The OB heads in the angled direction immediately, for all practical purposes. Although, with top or bottom spin, there is a very slight initial curve in the ball path. See the info and videos here: billiards.colostate.edu/faq/swerve/object-ball/ especially this video: ua-cam.com/video/XdjdgePMXFg/v-deo.html
When you put too much spin, you are not giving a lot of forward momentum to a cue ball. Ball travels with less speed, so the contact point does not transfer a lot force to a ball. So scratch that needs to create friction between balls is not enough applied to change direction, there is less friction. Also the speed of rotation is greater, so there is less time of contact between balls. In contrary, stop shot do everything opposite.
Unrelated to throw but I need this answer Dave. What’s higher percentage or more accurate over time… Regarding the speed of my shot, adjusting my bridge length and always bringing the tip of my cue back to my “V” and minimizing accidental left and right movement with my back hand OR keeping the same bridge length (say 12 inches) and adjusting the length of my backstroke? The first option is what I do and what feels comfortable and accurate to me but I’m curious your thoughts?
@@MagicMikeBilliards Either approach is fine, but the second approach is more common with better players who have straight strokes. See the videos and info here: billiards.colostate.edu/faq/bridge/length/
During the Max SIT section you say that using approximately half of the maximum sidespin generates the most SIT, but during the Thin Cut section you say to use extreme side to pocket the 8 ball. Are you using maximum sidespin on the thin cut to deflect the cue ball more, or to generate more SIT? Does the very thin cut change things regarding max SIT?
@@seanzie24 The amount of spin required for max SIT depends on cut angle. For more info, see: billiards.colostate.edu/faq/throw/maximum/ With a thin cut, maximum spin if required for maximum SIT.
Wow, Dave this is quite revelatory knowledge, feel like cheat code :) One question about cue butt, i know it is matter of personal preference, but does thickness play some roll in terms of feedback? Does it affect grip in case of size of the hands? Should players with bigger hands try thicker cue butt? I've noticed that you play with p3, that has thick cue but.
@@Brandzaman39 I’m glad you liked the video, but are you saying I have a big butt? 😲🤓 Seriously though, I think butt size is unimportant (unless you think it is, in which case it is). I just compared my P3 to all the other cues on my wall. They all have the same standard butt size.
@@DrDaveBilliards A thicker cue stick is supposedly meant to provide better feedback on impact, with less vibration, according to people who make cues. Speed control is certainly important, but we can’t perceive everything visually, nor even motorically, when it comes to fine adjustments, which can sometimes make a significant difference in positioning.
@@Brandzaman39 I personally think the importance of a cue's "feedback" or "feel" or "hit" are grossly exaggerated (especially by people who make and collect cues). See: billiards.colostate.edu/faq/cue/feel/ Seeing how the CB moves is all the "feedback" I need.
@@brendanknowlton9231 Many areas have juniors programs. Check with local pool halls and ask them if they know of any. Some pool halls also do tournaments during the day on weekends and allow juniors to play with supervision. BEF junior state and national tournaments is another option: www.billiardeducation.org/
I play every other week at a bowling alley using the supplied cues. Are there any quick tests I can do to determine how the cue will play? Your answer might help others in a similar situation, or somene just starting out, or someone who currently doesn't have the money to buy a cue, or are confused by the mind-boggling pool cue and tip options.
I still believe you have to hit the ball just before the rail if you play with outside english. The throw will float the ball in and makes the ball stick against to the rail on his way to the pocket
@@D.H.1987 If you use gearing outside spin, the most accurate option is to hit the ball and cushion at exactly the same time. See: billiards.colostate.edu/faq/sidespin/outside-gearing/ If you use more outside spin than that, you need to hit the ball first.
Thanks for the video Dr. Dave, but I’m wondering why pros like to use stun on their last ball rather than just topspin, especially for example in 9 ball, when the 9 ball is on its spot, since stun will cause more throw? Obviously, pros are really good at compensating for throw, but I feel like it’s better to keep it simple and rolling it is better than stunning the ball.
@@omg4life234 They often stun the last shot to guarantee no possible scratch. See the 45 degree rule here: billiards.colostate.edu/faq/cue-ball-control/45-degree-rule/ But they also don’t use slow speed. Faster speed reduces throw significantly. They sometimes also use a small amount of outside spin to reduce throw even more.
@@whartonjones The amount of spin required for max throw depends on the cut angle. For a straight shot, half of maximum spin is required. For an extremely thin cut, maximum spin is required. For more info, see: billiards.colostate.edu/faq/throw/maximum/
At 5:50 you say too much sidespin throws the ball less, but then at 8:20 you show maximum sidespin to throw the ball as much as possible. Is the amount of sidespin needed for maximum SIT dependent on cut angle?
Yes. 50% spin gives maximum SIT for a straight shot only. More spin is required at larger cut angles. For more info, see: billiards.colostate.edu/faq/throw/speed-effects/
Always a lot of 'fun' playing an opponent who doesn't understand throw, and you just made a ball 'that shouldn't be possible, so it must be a foul'. I always take care to explain what I'm about to do, and even sometimes ask for a neutral bystander to observe, to avoid discussions afterwards.
Throw me some physics, Doc! Hey, man... you still need a faster camera. Seems like a local college should have something like a good, fast digital camera around... I mean, heck, Boulder and NIST is right up the street. One would think you would have a good college over there... But at this point I'd almost bet that my 4k x 60Hz iPhone would cap better than that.
@@DrDaveBilliards I thought you said it was a GoPro. That is why I said that because my vids are pretty sharp even after UA-cam down-res-es them. Though I am not trying to capture a fast, short event, which my videos do show blur on as well. So yeah, even Best Buy's last years closeout models would be nice. Problem is they don't get marked down very far. I used to love buying a big screen TV that was hundreds off the orig price. Cameras... nope. But sure, any digital "slr" replacement that came into the world likely has a better frame rate. I still do not know how they write at the rates and array sizes we do get cheap. Thank God for Moore's law.
@ The main camera is a nice Canon camcorder. The shooter POV stuff is from a head-mounted GoPro. The rail cut shot slow motion stuff was from my iPhone.
@@DrDaveBilliards You should call the slo-mo guys and have them come over. I know their gear is overkill, but it would be fun to see them record a few events. I am still not happy with some shot analyses, such as the tip compression vid. Great for slow shooter, low compression events... but you know I shoot hard and I think the tip compression is different for a higher impact force and velocity 'moment'. Because my "soft" tips definitely allow me to get a slightly better 'grip on the tip' and apply a bit more more of the Mr. Twisty function we began using leather tips over our "clubs" or "billiards" on. That is what a cue was originally referred to as. Those Frenchies and their words...
Hi Dr Dave! Very curious about the physics of throw and how the mechanic equations showcase that this effect is maximum at slow speed and particularly for a stun shot. It is there any formulation available?

@@omg4life234 They often stun the last shot to guarantee no possible scratch. See the 45 degree rule here:
billiards.colostate.edu/faq/cue-ball-control/45-degree-rule/
But they also don’t use slow speed. Faster speed reduces throw significantly. They sometimes also use a small amount of outside spin to reduce throw even more.
I love you

At 8:36 you talk about using extreme right spin but in an earlier shot you said max SIT occurred at about half of max left/right. What changed?
@@whartonjones The amount of spin required for max throw depends on the cut angle. For a straight shot, half of maximum spin is required. For an extremely thin cut, maximum spin is required. For more info, see:
billiards.colostate.edu/faq/throw/maximum/
5:51 can you explain why, from a physics standpoint, more side spin results in less throw at the same speed?
@@jakehinkle1613 Yes. This is described in detail here:
billiards.colostate.edu/faq/throw/speed-effects/
At 5:50 you say too much sidespin throws the ball less, but then at 8:20 you show maximum sidespin to throw the ball as much as possible.
Is the amount of sidespin needed for maximum SIT dependent on cut angle?
Yes. 50% spin gives maximum SIT for a straight shot only. More spin is required at larger cut angles. For more info, see:
billiards.colostate.edu/faq/throw/speed-effects/
Always a lot of 'fun' playing an opponent who doesn't understand throw, and you just made a ball 'that shouldn't be possible, so it must be a foul'. I always take care to explain what I'm about to do, and even sometimes ask for a neutral bystander to observe, to avoid discussions afterwards.
Agreed. Making shots and winning games and matches with a little knowledge is fun.
Throw me some physics, Doc! Hey, man... you still need a faster camera. Seems like a local college should have something like a good, fast digital camera around... I mean, heck, Boulder and NIST is right up the street. One would think you would have a good college over there... But at this point I'd almost bet that my 4k x 60Hz iPhone would cap better than that.
@@cosmicraysshotsintothelight Agreed. I should purchase a fancy high-speed camera, but I think the iPhone 12 was able to show the important points.
@@DrDaveBilliards I thought you said it was a GoPro. That is why I said that because my vids are pretty sharp even after UA-cam down-res-es them. Though I am not trying to capture a fast, short event, which my videos do show blur on as well. So yeah, even Best Buy's last years closeout models would be nice. Problem is they don't get marked down very far. I used to love buying a big screen TV that was hundreds off the orig price. Cameras... nope. But sure, any digital "slr" replacement that came into the world likely has a better frame rate. I still do not know how they write at the rates and array sizes we do get cheap. Thank God for Moore's law.
@ The main camera is a nice Canon camcorder. The shooter POV stuff is from a head-mounted GoPro. The rail cut shot slow motion stuff was from my iPhone.
@@DrDaveBilliards You should call the slo-mo guys and have them come over. I know their gear is overkill, but it would be fun to see them record a few events. I am still not happy with some shot analyses, such as the tip compression vid. Great for slow shooter, low compression events... but you know I shoot hard and I think the tip compression is different for a higher impact force and velocity 'moment'. Because my "soft" tips definitely allow me to get a slightly better 'grip on the tip' and apply a bit more more of the Mr. Twisty function we began using leather tips over our "clubs" or "billiards" on. That is what a cue was originally referred to as. Those Frenchies and their words...
@ Easier said than done.

That means you still have room for improvement. 🤓

Actually, second. I was first! :)
@@DrDaveBilliards hahaha Touché!
Hi Dr Dave! Very curious about the physics of throw and how the mechanic equations showcase that this effect is maximum at slow speed and particularly for a stun shot. It is there any formulation available?
