I was playing pool recently, and I had one ball left and the black ball. Since it was my shot, I took it, I sunk the remaining ball I had, and the white ball then hit the black ball, sinking it. Does this person who was playing against win? Another time another opponent I played had his shot and his ball was right on the pocket. I didn't actually hit or touch his ball, but it still sunk. Does he get two shots for that?
