I saw two statements from Hal Houle on Johnny Archers web site:
"When players write to you, asking how to aim, your pat answer is to say that you get three feet back from the shot, then you shoot parallel lines. That is all hogwash. That is not how you aim. Why don't you level with these recreational players? You use the aiming system whereby you aim the center of the cue ball at the edge of the object ball for any and all shots. You know exactly what I am talking about. We both know about placing the cue tip either left or right of cue ball center, and you know why we do that. Get honest for a change. These recreational players are no threat. Tell them the truth. - Hal Houle"
"From HAL HOULE: WHY DON'T YOU LEVEL WITH THESE KIDS AND TELL THEM THAT YOU USE AN AIMING SYSTEM THAT INVOLVES AIMING THE CUE BALL CENTER AT THE EDGE OF THE OBJECT BALL ON EVERY KIND OF SHOT YOU SHOOT. THAT AIMING SYSTEM ALLOWS YOU TO BE ACCURATE AND CONSISTENT. YOU KNOW EXACTLY WHAT I AM TALKING ABOUT. I HAVE USED THAT SYSTEM SINCE 1934. I GOT IT FROM THE BEST PLAYER THAT EVER PLAYED POOL. RALPH GREENLEAF. YOU WERE GIVEN IT BY SOMEONE, JUST LIKE I WAS. YOU DID NOT DREAM IT UP. SO WHY DON'T YOU DO THE DECENT THING AND BE HONEST WHEN YOU TALK TO THESE RECREATIONAL PLAYERS."
Aiming at the edge of the object ball on every shot? Or placing the cue tip either left or right of cue ball center? What does he mean? Is it possible that Hal talks about the aim & pivot system?
