I would practice more on the big tables, not just to prepare for a day of gambling at the pool hall. Also, this guy that can't run 4-balls has a better chance of winning on a bar box. The fact that you prepared yourself for this game tells me that you need to get your game together a whole lot more before you start gambling with anybody. When I got back into pool in 2001 after a 30+ year layoff, a guy at the pool hall several years older than me, told me "you shoot too hard, and don't play anybody in here for money". After practicing a lot, I still feel like I am the worst pool player ever, but I can assure you that on my worst day, a guy that can't run 4-balls on a bar box would not beat me in a race to 5 or more, no way, I don't care how bad I am shooting.
If you don't have natural ability, or live in a pool room, the way you practice is very important. Plus gambling is a different game also. and the idea that you practiced on a 9 ft. table just to prepare for this game tells me that you are not ready to gamble. Either you are a good enough player to gamble or you aren't. I just don't think you have spent enough time practicing correctly to get out there and gamble.
