The incongruities of pool terminology can be puzzling for someone new to this game. How do you arrive at the 4 ½’x9’ measurements on a 4 ½’x9’ table? How do you use the diamond system for banking? A side pocket bank is okay, but a cross-corner bank will always be long because the corner “diamond” is not equidistance in relation to the playing surface. And what ever happened to these diamonds anyway? Is a ninety degree cut shot theoretically the maximum angle you can cut a ball? Knowledgeable players who have played bar table pool with the big ball know that with English it’s possible to exceed that maximum. Just some questions and observations for discussion and debate.
