thanks billyThere are many instances in which a tap foul can be used to lessen the effects of a problem situation.
One of the biggest , would be one ball on the table in front of your pocket and the cueball ends up in the jaws of the top pocket on the same side.
If I take a foul there and you take a foul and then I roll out to the center diamond on the top rail frozen , now there is still a ball in front of your pocket but there are 3 balls on the spot and 1 in your pocket. You need 2 of them and I need 3, I might still lose the game , but he has to do something more than roll the cueball the length of the table. At least I am still alive. I discussed this with a guy who almost never misses a ball, because he brought it up. He made the same shot Preacher Ronn made against Scott Frost , kicked hard at the ball trying to make it and scratch and banked it over in his hole 1 rail, absolutely by accident. When I showed him what I would have done he said Oh ,the opponent would have just made the ball, and broke the others out and won anyway, yeah sometimes he will , but sometimes he won't , how often do you think you will get craphouse lucky and make the ball? Once in a lifetime?
