With a single forward motion the cue stick I can take the cue ball from the foot rail, walk it up the table to the head rail, run it over to the corner pocket and jam it against the pocket facing for a corner hook. If I try that in my next one pocket game and claim that "I'm just taking a foul" I'll probably be laughed at and asked to pay for the game and the table time. This technique is about 200 years old. It was called "trailing" back then, and it was frowned upon.
At 14.1 there is a question about how much pushing/manipulating of the cue ball should be allowed. In the old days, some players taking a foul would push the cue ball into the side of the rack for what seemed like a couple of seconds. I think that should not be allowed as part of the game. At what point should such manipulation be banned? Clearly my table-length corner hook should be outlawed as not part of the game.
On a related point, with a single tip-to-ball contact, I have a technique that can move every ball on the table to specified locations. It takes a while, but the tip stays on the cue ball.
