I'm from the states, so be kind. Watching a U.K. Pool .Tour match and saw something I have never seen in any kind of cue game. Player breaks and runs down to the 8/black ball and misses shape. He can see his ball, but doesn't have a clear pocket. He shoots cue ball into black ball into opponent's ball. This knocks opponents ball out of the way, and he then shoots black ball into pocket to win the game. Why is he allowed to continue?
