I saw Smokey Bartlett in Jackson,Tn back in the early 90's do the Bert Kinister shot where the cue ball is in the jaws of the corner pocket,and the object ball is 6 diamonds away in a diagonal straight line.
You not only have to make the ball but you have to draw the cue ball back in a straight enough line to scratch.
He did it 3 times in a row after miscuing on the first try,and all 3 of them were hit well enough you actually heard the ball slap the back of the pocket liner on an old 8 foot Steepleton.
This was NOT on Simonis either,this was with a normal,clean Red Circle,and clean but old rubber backed Mali cloth. Tommy D.
