Folks:
What *game* are we talking about here?
BIH for games like banks, 14.1, and one pocket is just plain stupid, for lack of a better term. BIH behind the head string, yes. But full BIH anywhere on the table? Now you just destroyed some key aspects of the game, like intentional fouls.
I can see full BIH for rotation games, and even 8-ball. But not banks, 14.1, or one pocket.
However, methinks Push&Pool (aka Poolkillers) is getting at barbox 8-ball. Here, full BIH is a powerful punishment for not responding well to a safety.
