A question for Fran Re: The swipe stroke.

Fran, the different cue stick angle shows that if the tip isn't moving in line with the stick, then the CB must go in another direction - in other words, the two strokes produce different effective force directions, but the same amount of spin (effective tip offset).

Here's the same diagram rotated to illustrate that.

Nice try but that's not how the diagram was presented and even if so, the angle of the cue stick is still wrong and misleading.

1.) If you think my attempts (and Tom Ross' and Dave Gross' attempts) at swoop strokes are wrong or misleading, please post a video showing us how it should be done instead. If you don't have a camera or a smartphone, I'm sure you can find somebody with one. It is extremely easy to post video with Youtube, even if you have never done it before (and it would be very easy to find somebody to help if necessary). You can even film in slow motion with modern phones. For an example of how to do this, see: NV F.3 - Pool stun/draw/follow jump shots at various cue elevations, with smartphone slo-mo.


2.) Try the procedure clearly described and demonstrated in the following article and video:
"Swoop Experiment" (BD, August, 2015)
NV F.2 - Swoop Stroke Experiment - Can swooping create extra spin on the cue ball?
If you don't want to watch the entire video, the explanation and demonstration of the referenced test starts a the 6:34 point in the video. If you get different results than I got, please share your observations and data (and video, if available).


I look forward to seeing a proper swoop stroke along with a demonstration clearly showing that it can do something a straight stroke cannot do.

IMO, a straight stroke is much more reliable, consistent, and accurate for most people; but again, I am open to seeing demonstrations that might change my perception.

Thank you,
Dave



Let's stick to your video and your diagram. There are serious errors that I pointed out about them in this thread. What's important is that those reading this thread will think twice about this stroke before forming an opinion based on your erroneous diagram and simplistic and incorrect video.

Trying to justify an error is just another error, Dave. When you have nowhere to go, you do that whole "let's agree to disagree" thing.

You're welcome, Dave. I'm always happy to help and I hope you continue to experiment, now that you have the information I provided here.

Not trying to irritate but to peace make:

When someone says swivel or swipe I think of a stick that comes across center cue ball (if done right) not off center as in the diagram.

Matt,

Did you see my attempted swoop strokes starting at the 9:51 point in the video? The diagram certainly applies to them. I was not able to get maximum sidespin by contacting the CB closer to center (although I most certainly tried), and I thought I was swooping fairly fast (compared to the forward speed of the cue). Again, I would love to see Fran, you, or anybody else try the experiment and achieve maximum sidespin with a swoop stroke, striking closer to center ball. I would also love to see someone achieve more sidespin with the swoop stroke than is possible with a straight stroke under the careful controls of the experiment (although, I still think this is not possible).

Again, the experiment is clearly described and demonstrated in the following article and video:
"Swoop Experiment" (BD, August, 2015)
NV F.2 - Swoop Stroke Experiment - Can swooping create extra spin on the cue ball?
The explanation and demonstration of the referenced experiment starts a the 6:34 point in the video. If you or anybody else gets different results than I got, please share your observations and data (and video, if available).

Regards,
Dave

You mean because it doesn't contact the CB at or even right of center and then "swoop" across center? I think the assertion that such a contact can produce a meaningful shot is what's wrong and misleading.

At least Dave has taken the time and trouble to try to explain, test and illustrate what he thinks happens with a "swoop" stroke - all you've done is nip at his heels with unproven (even unillustrated) assertions.

Hi Matt.

I don't think I have ever been brave enough to start contact on the opposite side & may never have actually done that, at least not consciously, intentionally, but I have swiped my share & may have done so a bit inadvertently or perhaps even subconsciously.

That said, I have swooped them in the vertical direction too. For those, I am quite sure that I have started below the equator.

My point is that I think that starting on the opposite side is not the only swipe/swoop stroke definition.

It's sort of like hitting with 2.75 'tips' of normal english vs 3 'tips' of normal english.

Swiping from at or very near center is still swiping.

Best 2 Ya,
Rick

No one can do the shot as you describe it. I am not sure how you expect him to make a video of what can't be done. If you disagree, post your own video. Otherwise you are asserting without evidence.

Thank you kindly.
 
The angle of the cue stick should be perpendicular or near perpendicular ( a slight angle outward is acceptable) to the cue ball at the immediate point of impact, followed by the swooping motion as the tip is on the ball.

Actually, it is possible to achieve maximum sidespin with a stroke as Fran has described; although, it would be extremely difficult, and it would be nearly impossible to do so consistently. Regardless, it would not be an effective technique in actual pool playing on a real table.

The following diagram illustrates Fran's proposed stroke along with an equivalent straight stroke, both achieving maximum sidespin.

center-ball swoop.jpg

Again, I challenge anyone to attempt to create Fran's stroke at an actual pool table. I have tried very hard and could not come even close to maximum sidespin with a center-ball hit, even with a significantly-exaggerated swiping motion.

I would also like to see someone post a video showing what is considered a good swoop (or swipe) stroke.

I would also like to see someone generate more spin with a swoop stroke than is possible with a straight stroke, using the carefully-controlled experiment described and documented in my article and at the 6:34 point in my video. If you haven't tried it yet, please do so.

Regards,
Dave

What do you do when you swipe something?

you go from one side to ?
how many sides have a ball?.......
what determine a side?
For a question to be it has to be a answer.

Everybody does it in one way or another. Think outside the "billiard box" for a while.

Is it better to speak in riddles to widen people's thoughts or is it better to speak clearly and directly and focus them?

But to answer your questions:

In the standard way of speaking of billiard balls, each has ball two sides as viewed by the player in shooting position.

When I swipe something, I take it without permission.

Common usage determines a side. I suppose it all stems from human bilateral symmetry.

Some questions for you:

How many sides do you have?

to stand under a question is to be the answer, hence the question.

to know the answer is to be the question.

What you see from a angle - be the angle.

I have many sides.

I am the ball.

questions are meant to be answered to be fully understand.

Do it and the answer will come to you.

When you swipe the floors, - do you want to move something?

Hi Christian,

How have you been & where have you been hiding?

I hope all has been well for You & Yours.

Some do not understand your 'language' telling them to simply experiment & do to find the answers to THEIR questions.

All of the Best of Blessings to You & Yours,
Rick

Hi Rick, doing fine over here, speaking Swenglish as usual:).
I wish you and yours all the best.

The ball is a sphere, not a flat object. Look at pictures of spheres and let it come to you.

Sit on a training ball and feel it.
Place a ball on a flat board and move it around.

Angle in, angle out.

Everybody can and everybody knows, - we are all doing it in many aspects of life.

Connect the dots, a angle for a angle.....

Answers come from questions.

How do you flip a coin? Is there a arc there somewhere? Is there a swipe?

Where would you grab a big round stone to move it?

How do you put spin on a tennis, bowling, golf, soccer, basket etc ball?

Regards

Christian

Ps what we find interesting or irritating guides us, let go and follow the string - connect the dots. Be Open for everything and attached to Nothing.
You have to let go to get. Breathe in, breathe out, eat-?, drink-?
Forgive, For giving. Give to get......
I aim to please
