Was this a good hit?

Also if you watch Caudron's video, he say on a rail first hit, the CB will have a bunch of side spin on it coming off the rail, while on a ball first hit it will have mostly roll. The Tyler shot the CB seems to have mostly roll, very little spin.
 
Going by the video only (not the reaction of the balls), is inconclusive. If you go frame by frame, which is <> keys, there are 3 frames of interest. Immediately before contact, during contact (or as close to as possible), and after contact. The first frame that shows any motion of either ball shows both balls moving. Thus you can't determine purely from the frames which balls was hit first.
 
Slightly off topic, does anyone know what Tyler was playing on this shot? Here is the beginning of the shot, it starts at 37.18 if the link does not take you right there. I'm thinking he was maybe trying to hit the 3 into the 8, leaving the 3 there, and get the CB behind the 10. What do you think?

I think he either tried to cut it into the corner past the 8 and just hit it dogshit bad; or he was trying to stick the CB and send the 3 behind the 10.

Tyler wasn't having a good day in any event.
 
That was my first thought too. But look where the 4 is near the 9, and I think he had inside spin on it. So if he made the 3, he would not have been anywhere near the 4.
Yeah I agree after I rewatched it a few times - I think you got the intended play right. Even if he tried to cut the 3 into the 8 and hide the CB he hit it about as bad as possible.

Stealing Spartan's picture, if it was a rail first hit, wouldn't the CB have gone approx in the direction of the arrow? Since it would have hit very deep behind the 3?

If the CB rebounded at the same angle it approached the rail, it could be a fullish hit on the OB and could follow fairly straight after it.

If it hit the OB first it would move the OB a little so the rebound hit couldn't be as full - that might produce the angle you drew.

I think the fact that the CB follows as straight as it does after the OB means it must be a rail first hit.

Youtube player shows a split hit. The 3 ball moves simultaneously with the cue ball changing direction. IOW to the eye, the cue ball managed a perfect wedge - 90 degree <contact> will transfer no energy etc... although, subsequent frames show somewhat less than 180 degree alignment per the movement of the 3.
 
I think he hit ball first. (or ball and rail simultaneously) What do you think? 5 second clip: EDIT: The 3 does not hit the rail at the end of the clip. The only relevant question is if it was a ball first or rail first hit.

Who shot it? If it was Mika shooting then it was a foul. If Tyler was shooting then,,,Good Hit! :ROFLMAO::ROFLMAO:

Yep....
And if it hit rail first the cb would of lost most all of it's forward/natural/rolling movement if it hit Behind the ball and rail first.
Look at the cb travel after the fact.
It's impossible to hit behind the ball first, and have so much natural Forward rolling of the cb as it rolls across table.
Also, the cue ball rolled faster and was closer to the other long rail, when they both came to rest.
 
There is a third possibility that I think is what happened. The cue ball missed the 3 going in but was still in the cushion when it hit the 3 ball. I think that explains why the cue ball did not stop close to dead. Dr. Dave has a video and explanation of a shot doing that. Strange action on the cue ball.

In this situation, it's possible that the cue ball barely brushed the 3 going in. Like moved it less than the thickness of a hair. That means that you can't tell from the motion of the balls after the hit whether the hit was good or not. I think "no foul" is the correct call.
 
Rail first. Foul.
That's how it looks and how I'd call it if I was playing but the youtube shows the CB wedged in and subsequently both balls moving away from the cushion identically (give or take) until they separate. With a HS/HD camera you might be able to discern what happens but failing that, no call. Had I shot that, it would have been to drive the 3 to another cushion. With Styer, maybe he played to thin it.
 
Bad hit. you can stop the video and see that the cue ball has passed the edge of the object ball and is frozen on the rail and the 3 has not moved yet. Then the cue ball catches it on the way out.

Looks like a bad hit to me

Yep, and thus causing one to think ''rail first''. It's a legal shot that has so little movement of the obj ball it doesn't effect the forward motion of the cue ball. I've seen high speed 88 degree (example) cut shots on the short rail being cut into the corner, from 8 feet away that were an 2'' from the pocket and only moved 1/2 ''.
And I'm sure some of us have seen a ball clipped so thinly, that it rolled back into it's cloth dent.
 
IMHO, a foul should never be called unless you are certain it's a foul. If it needs this level of scrutiny the call goes to the runner
