Take a look at Mike Page's video (linked in my post above) for a convincing demonstration of that.That 30 degree deflection from 1/4 to 3/4 hit was incomprehensible to me until someone 'splained it. So many shots seem to come up wanting to roll a straight back bank that are on a scratch angle almost no matter where you hit the OB.
The principle works in reverse too. The CB's possible follow paths and draw paths mirror each other, if you squint a little.
Heh, heh. If you squint a little...
But I may be missing your point here. In what way does a draw off of a HBH mirror a natural roll off of a HBH?
Heh, heh. If you squint a little...
BTW, Page's gem about a HBH draw coming off at 90 degrees was a bona fide knock-your-hat-off gem! I wish I'd known that when I played lots of 9-ball! How many 9 balls did I miss pocketing by carom because I wasn't sure where to hit the OB?!

Not just a half ball hit - any hit. In the drawing below (not a half ball hit), imagine the "stun" line (tangent line) is a mirror. Then the "follow" path and the "draw" path are reflections of each other in this "mirror" (if they have equal spin at contact).Heh, heh. If you squint a little...
He has a real knack for zeroing in on the most important stuff and making it understandable. Everybody should visit Fargo Billiards (his renowned pool joint in Fargo, ND) and spend 'til it hurts.BTW, Page's gem about a HBH draw coming off at 90 degrees was a bona fide knock-your-hat-off gem!

I think Doc's talking about maximum draw, not stun. For a half ball hit, maximum draw brings the CB to a path about 90 degrees from the CB's original path (not the OB's path as in a stun shot). This is a handy rule of thumb (not exact) for tight position play - it's most accurate at slower speeds, I think.
More force (speed) means the CB's curve will be longer/flatter, as I said. "Stun" means the CB is sliding without forward or reverse rotation when it hits the OB (like a stop shot at an angle). It's well defined; if I "considered" anything else a stun shot I'd simply be wrong.
And I was answering Vapros. I answered you in another reply (with your name on it).
As usual, for a stun hit more distance means you hit lower and/or harder and less distance means you hit higher and/or softer. This is pretty basic stuff, Bill - do you really think the good players here need this much detail?YOU forgot the "distance" between the CB and OB!
How is "stun" achieved at shorter or more distance that is shown in the diagram?
