This is a great video on a topic that is one of the most important in my opinion, but that hardly gets mentioned with the frequency that it deserves. Most pool channels just talk about the game as if this doesn't exist and a lot of them talk about aiming systems or ghost ball aiming like it is full proof. But after having realized that you actually have to change aim slightly depending on the shot, I have drastically improved my game. Any player who is frustrated that they are missing shots without knowing why should learn about this.
If I can brag real quick, I just ran my first full rack of 9 ball! Such a great feeling! And I feel I owe most of it to Dr Dave's videos. Practicing drills he's shown to learn how and where the ball with go with spin, advice such as positive thinking, giving each shot 100% focus, getting back up if you aren't feeling the shot and start your routine again, cut induced throw/squirt/swerve, and many more. Thanks man!
I've been playing and running racks for years and it still feels good whenever I run one...What deflates my pride though is running a whole rack (especially 8 ball) and then blowing it on the money ball lol ...

A really nice way to demonstrate CIT if someone can’t visualize it is to use hockey pucks. Push one hockey puck into another at an angle and you can clearly see why throw occurs and why spin is imparted on the object ball
Good idea. I use poker chips for the same thing. Also, the slow motion videos here show it clearly with pool balls: billiards.colostate.edu/faq/throw/spin-transfer/
I new I could cut better with some out side English, but throw would often make me miss when I had to use other English for shape. All these things need to be worked out like you are doing.
Throw can make you miss outside spin cut shots too, if the amount of spin isn’t just right. For more info and demonstrations, see: billiards.colostate.edu/faq/sidespin/outside-gearing/

Would love to see a challenge where you rack 15 balls randomly and shoot them in order. I do this sometimes to practice my positioning in a fun way.
Thanks. I'm glad to hear it. I also like 15-ball rotation practice. Here's a collection of racks I filmed a while back: czcams.com/video/WkHiRBvutiw/video.html
I dont see myself really mastering all these factors until i get a pool table at home. Which isnt really possible because i dont have the room unfortunately. I dont have time to be practicing this at pool halls all the time. Sucks because i want to really learn all this and put it to practice but oh well. Hopefully one day ill have room for a table
Another well done video. I have improved my game a lot by your tips on how to compensate for CIT. My go to method is putting left or right side spin, and soft hits, since I'm usually playing on very fast cloth tables, and I like the benefit of 'bigger pockets' that slower speed hits give me. (not to mention less travel of the cue ball after contact, to reduce the risk of scratching). Thanks for producing the best explained 'mechanics of pool' videos on the internet! What happens if you need to put opposite, to CIT compensation, spin on the cue ball (inorder to avoid a scratch or make shape on the next ball)? Does that increase CIT even more?
Dr Dave thanks for another great video with practical information that we can all use on the table. I often would put low outside on those shots and now I know why I always overcut. I didn't realize that low had any effect so I thought it was the same as gearing English. By the way, what chalk do you recommend for less cling? Thanks again.
I'm glad you found the video useful. Some chalks definitely cause worse and more frequent cling. Tao Pyro seems to stick to the CB the least. See the videos and info here: billiards.colostate.edu/faq/chalk/comparison/
Even normal throw can have a significant affect on the line of a shot. And many people often mislabel a normal amount of throw as a "kick" (AKA "skid" or "cling").
Hey Dr Dave, huge fan. What happens if you did clinging chalk shot with gearing inside and outside spin? although this will probably never come up as a useful strategy, I was really curious how much you could offset the skid/cling.
With gearing outside spin, there would be absolutely no throw or cling. For demonstrations and more info, see: billiards.colostate.edu/faq/sidespin/outside-gearing/ The effect of inside spin (with or without cling) would depend on shot speed and angle, per the info here: billiards.colostate.edu/faq/sidespin/inside/ and here: billiards.colostate.edu/faq/throw/answers/ Enjoy!
For me it is hard to aim to over cut a ball because I instinctively tend to compensate and my brain does not want to aim to "miss" Should I go to ground zero to correct my compensation mistakes or how can I improve the compensation process?
I have an Olhausen table with simonis and the accufast cushions here at the house and rattling the ball in corners is always a concern when having to use English at high speeds...
I'm glad to hear it. When you are in a binge-watching mood, check out my library of over 430 videos here: czcams.com/users/DrDaveBilliardsvideos Enjoy!
It all has to do with the moment of impact as to the reason a hard shot with some draw does not flare... is because the impact is hard enough to rebound through the elastic spheres before the lack of left or right spin can transfer well as CIT. Also, the wobble on that throw shot is not merely the ball-to-ball grip during the equatorial impact, but the ball on the cloth coefficient completes the jolt that sends it wobbling as there is a momentary skid at that tangency as well though not as great an influence.
I think the video explains the physics accurately and simply. For more information, see: billiards.colostate.edu/faq/swerve/object-ball/ and: billiards.colostate.edu/tutorial/throw/ The elastic deformation of the balls is miniscule and unimportant compared to all the other effects.
Inside spin actually helps manage throw better in most situations, per the info here: billiards.colostate.edu/faq/sidespin/inside/ But this works only if you are good with compensating your aim for CB deflection: billiards.colostate.edu/faq/sidespin/aim/compensation/
I think we compensate for outside q ball deflection, and changing to be inside would take new adjustment. Some times it will be better for shape so we should learn all these.
Cue elevation makes an accurate hit more difficult, but all the effects covered are the same, except at faster speeds where the CB will be hopping some. For more info, see: billiards.colostate.edu/faq/cue/elevation/
I just bought Aramith Premium pool balls brand new; and I started seeing that chalk marks were staying in there often. But for my it didn't make sense since I thought all the chalks might be the same. Now in your video I heard that there are some chalks that leave chalk marks on pool balls more than other. Thanks for the info. Any recommendation on an inexpensive and good chalk to keep my new balls in good shape, Dr. Dave?
Taom chalk seems to be one of the best for not sticking to the CB. For more info, see the videos and results here: billiards.colostate.edu/faq/chalk/comparison/ Enjoy!
@@DrDaveBilliards I remember I watched this video a while ago, and I’ve watched again. I like the conclusions. Btw: seeing on Amazon how much costs just one cube of Taom chalk, that’s was not what I had in mind when thinking of inexpensive chalk Lol! However, I appreciate the suggestion.
@@DrDaveBilliards Yup, I looked for that one on Amazon and it's very affordable. Right now I'm just using the chalk the guy who gave me his pool table had. So, for now I don't need to buy new chalk. But I already know which one I'd look for when I need it. Thank you, Dr. Dave. You've been helpful and kind, as always.
Dave, does the amount of gearing outside spin applied to cancel out throw change depending on the cut angle or are you applying the same amount of spin or tip position no matter the cut angle? @DrDaveBilliards
Hi Dr. Dave! Great video. I just had a quick (physics) question: is swerve solely a product of the cue not being completely level (i.e. the downward force creates a swerve effect)? Or is the actual spin of the ball creating the serve as the ball travels forward? Also, with CF shafts, I know you mention one potential drawback is that the tip can contact twice and cause excess squirt, is there anything one can do to avoid that? Is it just a matter of learning your cue and how much spin you can put on a shot? Thank you!
Swerve is caused by a combination of cue elevation and sidespin. For more info, see: billiards.colostate.edu/faq/swerve/ With a very stiff shaft, a miscue can occur with a good hit at very large tip offset (close to the miscue limit), but it doesn't happen with typical modern CF equipment.
Thanks. The beard would be very gray now. Maybe I'll grow it again when I get older and want to do a full head and face of gray for a distinguished and crazy professor look. :)
@@DrDaveBilliards It can be a nice idea for your videos. I feel easier to aim with outside spin but mostly fail with inside spin. I can see Efren use inside very well even very long soft shot.
@@thangthang4808 FYI, I already have videos dealing with how to aim when using sidespin (including inside) here: billiards.colostate.edu/faq/sidespin/aim/compensation/
To me the least amount of throw occurs when there is both Gearing and draw used to form a "spin vector" at the OB strike point, which can then be implemented at a slower overall speed or faster and get the same result. Watch out for the scratch, however, when using gearing English and speedier shots.
With "gearing outside spin," there is absolutely no throw. Backspin is not required. For more info and demonstrations, see: billiards.colostate.edu/faq/sidespin/outside-gearing/ Although, with backspin drag shots, you can use less sidespin to the get the "gearing" effect. For more info, see: billiards.colostate.edu/faq/sidespin/drag/
Dave I'm not sure I see any spin being imparted to the object ball. Sure the stripe is wobbling because it's no longer exactly vertical after the object ball is thrown, but if it were genuinely spinning wouldn't the stripe be rotating only in one direction, not wobbling back and forth? There are several coaches on CZcams who are adamant that induced spin is a myth and appear to prove it using slow motion cameras for certain shots such as straight shots using side. This has gotten me quite confused as there appears to be differing opinions on this from different sources.
There are also people who insist the Earth is Flat! Undisputable and conclusive proof that spin transfer exists can be found in the videos and other resources here: billiards.colostate.edu/faq/throw/spin-transfer/ Enjoy!
@@DrDaveBilliards Even this test doesn't seem to my eyes to be an argument for induced spin though. The 'wobble' effect is simply the result of the stripe not being vertical. Which could be caused by a small amount of deflection or throw. I.e. My point is that the 'wobble' is not spin. How do you prove otherwise?
@@dhirajpallin2572 I think the videos and resources on the resource page provide undisputable visual, shot-example, and math/physics proofs: billiards.colostate.edu/faq/throw/spin-transfer/ If you know anybody who doubts spin transfer, please refer them to this page so they too can be convinced.
@@DrDaveBilliards Dave I watched the video you linked, but in the video you are still just making the point that because the stripe isn't vertical it means there was spin transfer, when as I said this can still just be accounted for by the throw alone. It doesn't prove there is spin on the object ball. Only that the throw pushes the ball off vertical (which I guess could be considered temporary spin, but only for a split second). How do I know from these videos that the cushion deflection angle is due to spin or simply due to throw changing the angle coming into the cushion?
Both and pool and snooker players need to adjust aim for throw. Most top players do this by feel, but it helps to know the important principles summarized at the bottom of the page here: billiards.colostate.edu/tutorial/throw/ Object ball swerve on the other hand is too small of an effect to be concerned with.
Ghost Ball works fine as long as you adjust the ghost ball target slightly to account for throw when necessary. For help, see the videos and info here: billiards.colostate.edu/tutorial/throw/ Enjoy!
Hello Dave, thank you for the video. If one would oil the OB, this should remove the CIT? Oil on the table is not nice so I am thinking to wax. I just want to know if I hit the geometrically corect point in practice. How to separate trow from aiming, learn aim without trow and then add the compensation based on the shot?
Waxing the balls can dramatically decrease throw. The only problem is: the amount of throw changes as the wax wears off with play. Fore more info, see: billiards.colostate.edu/faq/ball/cleaning/
@@DrDaveBilliards omg. Thank you for the experiments. Silicon spray it is. Can you advertise some, or any kind will work? Just want to have this pure ghost ball aiming filling for some practice. P.S. Nice work on deriving the throw equations.
@@vyacheslavboyko6114 I don't recommend Silicone Spray. It is very messy, and it gets on everything (cloth, tip, and you), and it is tough to clean off.
@@DrDaveBilliards So what do you recommend? I cannot spit on the balls every shot XD. Should I search for a wax? But wax doesn't reduce the throw entirely 🙄
@@DrDaveBilliards I tried Wax und some lubricant. The wax worked best, however, it is a bad practice to wax the contact point every 2 or 3 shots. So the wax will slowly transfer to the table cloth in 100 -1000 shots. Well, now I am thinking to learn the aiming with natural throw. For that I will 3d print a ramp to accelerate the white ball and measure the trow of natural roll contacts.
3:19 gearing outside spin has almost no deflection i have noticed since you’re not hitting the cue so far to the side. Im kinda surprised you dont know this 🤔
It depends on the cut angle. For small cuts, the amount of spin and CB deflection are small; but for larger angles, the amount of spin and CB deflection are much larger (especially with a non-LD shaft).

Pros have a good intuitive sense for most pool physics stuff; although, even pros fail to properly compensate their aim for throw at times. I see it all the time.
Did you mean: "The game is 90% mental. The other half is physical." FYI, many quotes like this that apply to pool can be found here: billiards.colostate.edu/maxims/ Enjoy!
Please someone explain overcut throw aim in relation to his initial ghost ball marker setup. I’ve seen other videos say to do this but they never really tell you how. This is definitely a source of my misses right now I’d definitely love to start workshopping immensely.

@@DrDaveBilliards I was imitating a diagram you have where the OB is Center table facing to a side pocket and a CB is about 15 degrees out exaggerating speed from slow to fast to get the feel then adding suggested spin. Do you have drills I could purchase or you recommend to work on thin/thick anti swerving shots? I’m also learning I hate big pockets!

Great video!! Where did you get that practice ball with the black line?? Looks usefully for training
It is part of the "Elephant Practice Ball" set. You should be able to find it online.
Hey Dr Dave, huge fan. What happens if you did clinging chalk shot with gearing inside and outside spin? although this will probably never come up as a useful strategy, I was really curious how much you could offset the skid/cling.
With gearing outside spin, there would be absolutely no throw or cling. For demonstrations and more info, see:
billiards.colostate.edu/faq/sidespin/outside-gearing/
The effect of inside spin (with or without cling) would depend on shot speed and angle, per the info here:
billiards.colostate.edu/faq/sidespin/inside/
and here:
billiards.colostate.edu/faq/throw/answers/
Enjoy!
Thanks Doc!
You're welcome!
For me it is hard to aim to over cut a ball because I instinctively tend to compensate and my brain does not want to aim to "miss" Should I go to ground zero to correct my compensation mistakes or how can I improve the compensation process?
I have lots of good aiming advice here:
billiards.colostate.edu/faq/aiming/dam/#advice
Check it out.
I have an Olhausen table with simonis and the accufast cushions here at the house and rattling the ball in corners is always a concern when having to use English at high speeds...
Love your vids.
I'm glad to hear it. When you are in a binge-watching mood, check out my library of over 430 videos here:
czcams.com/users/DrDaveBilliardsvideos
Enjoy!
It all has to do with the moment of impact as to the reason a hard shot with some draw does not flare... is because the impact is hard enough to rebound through the elastic spheres before the lack of left or right spin can transfer well as CIT. Also, the wobble on that throw shot is not merely the ball-to-ball grip during the equatorial impact, but the ball on the cloth coefficient completes the jolt that sends it wobbling as there is a momentary skid at that tangency as well though not as great an influence.
I think the video explains the physics accurately and simply. For more information, see:
billiards.colostate.edu/faq/swerve/object-ball/
and:
billiards.colostate.edu/tutorial/throw/
The elastic deformation of the balls is miniscule and unimportant compared to all the other effects.
Does inside spin affect the throw? Because I have always heard its harder to pot with inside spin as oppose to outside spin
Inside spin actually helps manage throw better in most situations, per the info here:
billiards.colostate.edu/faq/sidespin/inside/
But this works only if you are good with compensating your aim for CB deflection:
billiards.colostate.edu/faq/sidespin/aim/compensation/
I think we compensate for outside q ball deflection, and changing to be inside would take new adjustment. Some times it will be better for shape so we should learn all these.
What about if you throw cue elevation to the mix with this same test? Hampered, close to the cb etc
Almost always when i miss, i dont cut enough : )
Cue elevation makes an accurate hit more difficult, but all the effects covered are the same, except at faster speeds where the CB will be hopping some. For more info, see:
billiards.colostate.edu/faq/cue/elevation/
Hitting shots too full is sometimes an aiming problem; but as my video showed, it can sometimes be due to not compensating for throw.
I just bought Aramith Premium pool balls brand new; and I started seeing that chalk marks were staying in there often. But for my it didn't make sense since I thought all the chalks might be the same. Now in your video I heard that there are some chalks that leave chalk marks on pool balls more than other. Thanks for the info.
Any recommendation on an inexpensive and good chalk to keep my new balls in good shape, Dr. Dave?
Taom chalk seems to be one of the best for not sticking to the CB. For more info, see the videos and results here:
billiards.colostate.edu/faq/chalk/comparison/
Enjoy!
@@DrDaveBilliards I remember I watched this video a while ago, and I’ve watched again. I like the conclusions.
Btw: seeing on Amazon how much costs just one cube of Taom chalk, that’s was not what I had in mind when thinking of inexpensive chalk Lol! However, I appreciate the suggestion.
@@rapanchoo Master chalk is fine, and very cheap.
@@DrDaveBilliards Yup, I looked for that one on Amazon and it's very affordable.
Right now I'm just using the chalk the guy who gave me his pool table had. So, for now I don't need to buy new chalk. But I already know which one I'd look for when I need it.
Thank you, Dr. Dave. You've been helpful and kind, as always.
Dr Dave should rename himself to Professor Dave 👍👍👍
FYI, I was a university professor for 30 years. For more info, see:
billiards.colostate.edu/dr-dave/
@@DrDaveBilliards I knew it 😊👍👍👍
Dave, does the amount of gearing outside spin applied to cancel out throw change depending on the cut angle or are you applying the same amount of spin or tip position no matter the cut angle? @DrDaveBilliards
It is different for every cut angle. See the 40% Rule stuff here:
billiards.colostate.edu/faq/sidespin/outside-gearing/
Hi Dr. Dave! Great video. I just had a quick (physics) question: is swerve solely a product of the cue not being completely level (i.e. the downward force creates a swerve effect)? Or is the actual spin of the ball creating the serve as the ball travels forward?
Also, with CF shafts, I know you mention one potential drawback is that the tip can contact twice and cause excess squirt, is there anything one can do to avoid that? Is it just a matter of learning your cue and how much spin you can put on a shot? Thank you!
Swerve is caused by a combination of cue elevation and sidespin. For more info, see:
billiards.colostate.edu/faq/swerve/
With a very stiff shaft, a miscue can occur with a good hit at very large tip offset (close to the miscue limit), but it doesn't happen with typical modern CF equipment.
@@DrDaveBilliards you’re the best Dr. Dave! Thank you!!
Great stuff doc. I just bought your book, when are you gonna grow back your beard?
Thanks. The beard would be very gray now. Maybe I'll grow it again when I get older and want to do a full head and face of gray for a distinguished and crazy professor look. :)
@@DrDaveBilliards Are you implying that you aren't already a crazy, distinguished professor? Ahaha
It's ok I am growing mine to compensate
@@Fenomenoe9 How about a mullet to go with it? :)
@@DrDaveBilliards haha, Dr dave pushing his luck :D
Hi @Dave, can you explain how inside spin effect the throw, swerve. Thanks
See:
billiards.colostate.edu/faq/sidespin/inside/
@@DrDaveBilliards It can be a nice idea for your videos. I feel easier to aim with outside spin but mostly fail with inside spin. I can see Efren use inside very well even very long soft shot.
@@thangthang4808 FYI, I already have videos dealing with how to aim when using sidespin (including inside) here:
billiards.colostate.edu/faq/sidespin/aim/compensation/
@@DrDaveBilliards Thank Dave
To me the least amount of throw occurs when there is both Gearing and draw used to form a "spin vector" at the OB strike point, which can then be implemented at a slower overall speed or faster and get the same result. Watch out for the scratch, however, when using gearing English and speedier shots.
With "gearing outside spin," there is absolutely no throw. Backspin is not required. For more info and demonstrations, see:
billiards.colostate.edu/faq/sidespin/outside-gearing/
Although, with backspin drag shots, you can use less sidespin to the get the "gearing" effect. For more info, see:
billiards.colostate.edu/faq/sidespin/drag/
Dave I'm not sure I see any spin being imparted to the object ball. Sure the stripe is wobbling because it's no longer exactly vertical after the object ball is thrown, but if it were genuinely spinning wouldn't the stripe be rotating only in one direction, not wobbling back and forth? There are several coaches on CZcams who are adamant that induced spin is a myth and appear to prove it using slow motion cameras for certain shots such as straight shots using side. This has gotten me quite confused as there appears to be differing opinions on this from different sources.
There are also people who insist the Earth is Flat!
Undisputable and conclusive proof that spin transfer exists can be found in the videos and other resources here:
billiards.colostate.edu/faq/throw/spin-transfer/
Enjoy!
Concerning stripe wobble, the next time you are at a table, hit a stripe with a small amount of sidespin, and you will see the wobble.
@@DrDaveBilliards Even this test doesn't seem to my eyes to be an argument for induced spin though. The 'wobble' effect is simply the result of the stripe not being vertical. Which could be caused by a small amount of deflection or throw. I.e. My point is that the 'wobble' is not spin. How do you prove otherwise?
@@dhirajpallin2572 I think the videos and resources on the resource page provide undisputable visual, shot-example, and math/physics proofs:
billiards.colostate.edu/faq/throw/spin-transfer/
If you know anybody who doubts spin transfer, please refer them to this page so they too can be convinced.
@@DrDaveBilliards Dave I watched the video you linked, but in the video you are still just making the point that because the stripe isn't vertical it means there was spin transfer, when as I said this can still just be accounted for by the throw alone. It doesn't prove there is spin on the object ball. Only that the throw pushes the ball off vertical (which I guess could be considered temporary spin, but only for a split second). How do I know from these videos that the cushion deflection angle is due to spin or simply due to throw changing the angle coming into the cushion?
Thank koch
I wonder, do professional players think about this or do you just play by feel? Also is this more of an issue in snooker?
Both and pool and snooker players need to adjust aim for throw. Most top players do this by feel, but it helps to know the important principles summarized at the bottom of the page here:
billiards.colostate.edu/tutorial/throw/
Object ball swerve on the other hand is too small of an effect to be concerned with.
My head is spinning. Basically ghost ball doesn't work is what you're saying. I am missing shots quite a bit that I'm left scratching my head.
Ghost Ball works fine as long as you adjust the ghost ball target slightly to account for throw when necessary. For help, see the videos and info here:
billiards.colostate.edu/tutorial/throw/
Enjoy!
Hello Dave, thank you for the video. If one would oil the OB, this should remove the CIT? Oil on the table is not nice so I am thinking to wax. I just want to know if I hit the geometrically corect point in practice. How to separate trow from aiming, learn aim without trow and then add the compensation based on the shot?
Waxing the balls can dramatically decrease throw. The only problem is: the amount of throw changes as the wax wears off with play. Fore more info, see:
billiards.colostate.edu/faq/ball/cleaning/
@@DrDaveBilliards omg. Thank you for the experiments. Silicon spray it is. Can you advertise some, or any kind will work? Just want to have this pure ghost ball aiming filling for some practice. P.S. Nice work on deriving the throw equations.
@@vyacheslavboyko6114 I don't recommend Silicone Spray. It is very messy, and it gets on everything (cloth, tip, and you), and it is tough to clean off.
@@DrDaveBilliards So what do you recommend? I cannot spit on the balls every shot XD. Should I search for a wax? But wax doesn't reduce the throw entirely 🙄
@@DrDaveBilliards I tried Wax und some lubricant. The wax worked best, however, it is a bad practice to wax the contact point every 2 or 3 shots. So the wax will slowly transfer to the table cloth in 100 -1000 shots. Well, now I am thinking to learn the aiming with natural throw. For that I will 3d print a ramp to accelerate the white ball and measure the trow of natural roll contacts.
this is gospel
I'm glad you think so. Hallelujah!
Good
Thanks.
3:19 gearing outside spin has almost no deflection i have noticed since you’re not hitting the cue so far to the side. Im kinda surprised you dont know this 🤔
It depends on the cut angle. For small cuts, the amount of spin and CB deflection are small; but for larger angles, the amount of spin and CB deflection are much larger (especially with a non-LD shaft). For more info, see the videos, illustrations, articles, and other resources here:
billiards.colostate.edu/faq/sidespin/outside-gearing/
The closer to stun, the greater the throw.
Bingo.

Do pro players know this stuff when they r in their hustle-time, or do they get to know these things when they start their pro careers??... I am refering my question to American and Philippinian players, I think in Germany(I happen to live here)thers exisits a more classic way to become a pro player, u always Start as an amateur player by getting coaching and participating in tournaments where u represent your club...in any sports
Pros have a good intuitive sense for most pool physics stuff; although, even pros fail to properly compensate their aim for throw at times. I see it all the time.
Basically cut it thinner for slow speeds, hit it thicker if you gonna bang. That’s all you need to know if you’re under 600 fargo which you are.

Please someone explain overcut throw aim in relation to his initial ghost ball marker setup. I’ve seen other videos say to do this but they never really tell you how. This is definitely a source of my misses right now I’d definitely love to start workshopping immensely.

You're welcome. I aim to swerve (and to throw). :)
@@DrDaveBilliards I was imitating a diagram you have where the OB is Center table facing to a side pocket and a CB is about 15 degrees out exaggerating speed from slow to fast to get the feel then adding suggested spin. Do you have drills I could purchase or you recommend to work on thin/thick anti swerving shots? I’m also learning I hate big pockets!
