The way it looks like its done on a break, it looks like you aim at the bottom of the ball as if you were going to illegally jump it. Then do your practice strokes the on your last stroke your stroke arm comes up then goes down in a scoping motion and the cue ball is hit just below center ( considerably higher than you aimed) or that's the illusion. I'm told its called flat stroking and I've seen some players do it just on the break and some players on every ball. I've seen some Asian players do it. Can't find any specific videos demonstrating it. But if anyone knows what I'm talking about please pm me or explain the mechanics behind it
