Can you influence the cb while it is rolling?

I keep my eyes open for ways people cheat, and I heard something interesting on the broadcast between vietnam and USA. Announcer said that the vietnamiese were tapping the table (rails) to slow down the cb for position. He said it should be illegal, but it isn't. He said it was an effective way to slow the rolling ball down, using either the fingers or the chalk. They weren't using much force at all to tap the rail. I always thought this was a "nervous tick" habit, but could it work? I don't think you could do anything about it in leagues, but it would be interesting to confront someone if it does work.

I've heard it's something about sending vibration waves through the table/slate which slow the roll. My guess is that the change, if any, is infinitesimally small. May have more of a sharking impact on your opponent than any impact on the cueball. :p
 
hard to dismiss out of hand

Since it has to transfer though different materials I would suspect natural dampening to occur however the show "mythbusters" was able to get a very noticeable vibration traveling through a bridge for several hundred feet just tapping on it with a few ounces I believe.

If the rhythm of the tap matched the harmonics of the material getting the slate to vibrate substantially might be possible since each tap would add to the returning harmonic. I have no idea how likely this is to work but I surely wouldn't count on it.

I agree, it sounds silly

I thought it sounded silly too, but Kim was not joking, he was actually slightly disgusted that the vietnamese were doing it. He said in the broadcast it was fact. I think Kim is pretty smart, so I got to thinking. Anyone else hear it in the broadcast? Anyone else ever hear of this?

I remember Larry Blazer complaining one time that Chuey Rivera did something similar in a match. They were playing and Chuey was running out. The CB was traveling straight for the corner pocket and Chuey hit this table hard with the flat of his hand and the CB stopped cold. Larry thought it should have been a foul but the TD ruled that since he didn't touch a ball, it wasn't.

I tried it several times and was unable to make the CB stop consistently, but it seemed to work sometimes.

As for a gentle tapping, it doesn't seem to me like it would work...but crazier things have happened.

Cheers,

Yeah, but Irving Crane used to believe wholeheartedly that cueball spin could not transfer spin to an object ball....

Just because a really good player believes something way down deep in their soul doesn't mean anything, unless they can prove it.

i think it's baloney,,,,,,,oscar meyer baloney.

a question nonetheless,,,how has this phenomenon been measured??????????????? and i don't mean slamming the side of the table with a truck,,,,i mean "tapping" as the op says.

"the anouncer" said the player was tapping the rails. that means the rubber to me. so he's saying when tapping the rubber the vibrationn transfers along this totally nonconductive material, along slate, along cloth, and makes the cb slow down. or maybe the player was tapping the wood...yeah, that's it . from the wood to the slate to the cloth. maybe it was a table length shot and the vibration could be felt all the way down there. or maybe it wasn't, but the player was keenly aware of effective range of his tapping.

as the cb was crawling at x cm per minute, did the announcer notice the cb slowing down to x-y cm per minute. I KNOW,,,the announcers got this bit of info from several pool players!!!

I'm not so sure I can agree with Kim on this one. I have never heard of this before, and I find it doubtful.
 
i believe i caught the culprit!!

was it done with a jackhammer? unfortunately, this extreme measure rendered the table useless.

Since the merest momentary flicker of a man's eyes in the direction of another attractive woman, when he is standing 50 feet away from his wife in a crowded room, can create minute changes in air waves which vibrate against his wife's antennae and cause her upper lip to curl, even when the said flicker of the eye took place out of her line of view when her back was turned........this cue ball theory is entirely believable:)

Do not forget - Chewy racks the balls, and slow plays better than anyone in the USA.

All you East Coast guys or MidWest dudes, get down in CO. We gamble. 303 810 4123.........

Good point, and you didn't even mention about how when the wave bounces back from the guys wife it can hit him with an incredibly increased impact!!;) :eek:

Freaking jackhammer gnomes keep ruining the tables around here too! It's time for the Dept. of Homeland Security to get serious about this problem. Illegal jackhammer gnome immigration is the number one problem facing American pool today!

Great pic!

I was so curious about this one that maybe we should ALL write to the guys at Myth Busters and see if we can get them to test it!
 
I think it's a load of crap. Who's to say that the vibration doesn't actually speed the cue ball up?

Somebody should tell them it would be easier just to play the speed right in the first place...
 
more detail

If I remember correctly when Kim made this comment was during a partners game. When it appeared the cue ball would scratch the shooter's partner begin tapping frantically on the wooden part of the rail, not a cushion.

I noted the claim at the time but only in passing. I don't remember how fast the cue ball was rolling or what the eventual outcome of the shot was. I believe the partner was using a chalk cube, don't remember for sure about that either.

I'm skeptical of this working but it might stop a slow rolling ball an inch or two shorter or perhaps deflect the path enough to keep a cue ball barely out of a pocket if it was going to fall. This wasn't the gentle tap of a finger on the table some people have in their bridge hand. Anyone who has watched curling knows that it doesn't take much to change the course of those monster pieces of rock, hard to say absolutely that you can't affect the path of a cue ball without testing.

As I said earlier, I am skeptical of this. However, someone would do it just once if they were playing me for serious dollars or in a tournament. I would warn to expect a gentle tap upside the head with a cue stick on the second attempt and would deliver on any second attempt. I think that what annoyed Kim was the attempt to manipulate the cue ball, successful or not.

I have seen the CB slowed by hitting the table. I'm talking a good smack, not a tapping. The CB noticebly slowed down and came to a stop 2-4" quicker than it should have. This would be easily proven with a little Engineering know-how or simple experiment at your favortie pool hall (when the owner isn't looking).

Tapping on the other hand would have no significant effect. In fact, I would categorize that with the people that put their hand up in the policeman's pose as if it will somehow slow the CB. Face it, we are funny beings. We even push on imaginary brake pedals when riding with an aggressive driver.
