I have been playing off and on for almost 2 years now. I still have not gotten a break and run in 9 ball. I can break and run to the 8 ball a few times a week. I average running to the 4 or 5. I have never pulled it off in 8 ball either. I have come to the table after my opponent had a dry break and run out in 8 ball. I think it is in my head. I find it very frustrating. I have a table at the house I play on must of the time. It is a bar box with shimmed pockets. The corners are 4 1/4 and the sides are 4 3/4.
