But the fact remains that if you do manage to hit the ball and the cushion at the same instant, contact-induced-throw will push the object ball into the cushion and you will miss the pocket completely for long shot, rattle the ball for medium shots, and maybe make the ball for short shots with ample pockets. Of course this assumes you do not have outside gearing side spin on the cue ball.
Telling a beginner to hit the ball and cushion at the same instant for frozen rail shots is very bad advice. It is better to tell them the truth.
So, you kind of agree with the original post? This might be a first for me on AZB! I'm really excited as I respect yours and Dr. Dave's opinions. I've added to the OP by including how I drill on this shot. Thanks.
