Larry,i dont see how you can make the cue ball go backward then go forward....
if it goes along the tangent line and hits the top of the stripe i could see the follow english getting the cue ball go as diagrammed
but the stripe would have to go to the side rail
great imaginative shot tho....
If the two balls are close enough together, meaning that the hitting of the ball to be banked and the ball to be forced backwards is almost simultaneous, then the shot works. The forced ball will move directly backwards towards the pocket and the banked ball, if hit decently should either make or hang in the pocket.
The CB if hit with high RHE will move up table almost exactly like Dave showed it. Only thing that could possibly be wrong with this shot is the separation between the two balls, if it's to wide, then the shot will fail. To me it's very close, looks like it's doable, I'm just disappointed I didn't see it before.
It would be my choice if the two balls laid right. Good shot Dave and way to look over the table!
PS... The high applied to the CB will actually draw the CB slightly off the ball to be banked, helping close the gap between the two balls.
