sounds like what some of the ol' masters called "tuck and roll". center ball but with slight movement of tip at the moment of impact. these movements are tiny but can have major effects.
Can someone tell me where the center of the cueball is?

Thanks for the help.That's makes alot of sence to me."the core"
One reason I ask this ? is, it seems like I can get alot more turn on my object ball than most people that I try to help,yet my cball doesn't seem to have any noticeable turn or spin on the cball with the shots I'm thinking about.Which are bank shots by the way.I just think that on some shots I use a little different angle going through the cball (not a 100% sure though) If I do it it's very slight and hardly noticeable.John B.
IF I remember correctly, Dr. Dave, in his slow motion video DVD , he said that once the tip hits the surface of the ball it leaves faster than you could ever do what you asking John. The rebound of the ball off of the tip happens to fast to influence the direction or path by moving off of a straight path.
But if the cue is rotating prior to making contact, the friction between the tip and ball will act somewhat like ball-ball friction (i.e., throw):IF I remember correctly, Dr. Dave, in his slow motion video DVD , he said that once the tip hits the surface of the ball it leaves faster than you could ever do what you asking John.

There's no real advantage to it as the same thing can be achieved with a perfectly straight stroke, and likely more accurately:
Affecting the cueball's spin/direction with a swiping stroke becomes less and less doable as you move away from centerball.....unless your stroke becomes nothing much more than a monstrous swipe.

I am confident, John, that the swiping or swooping or nipping or whatever people want to call it is not what's causing the difference you notice.
You are like a circus dolphin trying to teach turtles to jump gracefully through a hoop ;-)
Seriously, though, to get the most turn requires getting the highest spin-to-speed ratio on the object ball when the object ball reached the cushion. And this is a subtle thing. It's not the same thing as getting the most spin (i.e., highest spin-to-speed ratio) on the object ball right away. You do that by stunning the cueball into the object ball at low speed. But that spinning object ball loses it's spin on the way to the cushion. So it's a tradeoff: you have to hit it a little harder, getting less initial spin but retaining more of that spin at the cushion.
You know all of this stuff instinctively --just how to hit it to maximize the turn when the object ball is a certain distance from the rail on particular cloth.
Is this for shots where the object ball is cut by about 20-30 degrees?... But can you explain how I turn the object a lot without turning the cball any? ...

Mr. Jim,
Well stated. Many want to elude to the very short tip contact time as making some things impossibly. However if the motion is incorporated or put into operation prior to contact some or many of those things can be accomplished, especially with a soft tip that allows maybe as much as twice the contact time of a hard tip.The effects may seem small, but even 1 mm can make the difference between a ball that drops & one that gets rattled or ponited out. To me, any difference IS significant.
Best Regards to You &
