Like you, I'm an old school guy. We were on the hunt every day just looking for a game and weren't too particular about who, what and where. Just put your stick together and get it on. Let the best man win. I'd walk into a poolroom prepared to play anybody, any game on any table in the house! Most of the time it was 9-Ball back then, One Pocket second most popular (I guess some things never change). Occasionally I played Banks, Eight Ball (almost exclusively on bar tables), and even gambled a few times at Pay Ball on the 10' snooker table, a little Three Cushions and some 14.1 on the East Coast.
Any game was better than no game and we had to adjust to the conditions whatever they were. Table rolls, dead cushions, chipped balls, obstructions, bad cues, all of that. It was all part of the game! My attitude back then was that if I was a better player it would show up no matter what game we were playing. And most of the time I was out there on the lonesome, no one to back me up but myself.
The education I got and the confidence I gained during that time in my life helped me immensely in whatever success I achieved later on.
