JimS:
Cheating the pocket would mean hitting the ob with less than a 1/2 ball hit meaning that most of the energy of the shot was obsorbed by the ob and the cb wouldn't roll as far as the ob. Right? Hitting above center on the cb won't make any difference as the speed of the shot means no follow would be applied.
For a spot shot, 1/2 ball aim only makes from within a few inches of the head spot. Shooting from near the rail takes a significantly fuller aim.
Also, it's a 45-degree cut that makes both balls travel equal distances after contact. That's closer to a 1/4 ball aim and much too thin for this shot. Since the OB is farther from the corner pocket than from the foot rail, you need the OB to travel farther than the CB, so you need a fuller hit than 45 degrees - in fact, you need a fuller hit than 1/2 ball aim.
You're right about the rest.
