There was a trick snooker table set up in Bill's Recreation Center, no relation, in Jackson, MS in the 60s and 70s. The table was mainly used for golf games. One of the side pockets was "Fixed" and as most of you know, the side pockets are everything in golf. On this table if you rolled the object down the rail, at just the right speed, it would roll off and into the side pocket.
One of the top players in Memphis at the time was a black guy they called Black Danny. He played all games well. Not top speed but well. Danny comes into Bill's asking to play anyone any thing. The top golf player in town, not me, told him he would play him some golf and pointed to the trick table. Danny agreed and the game was afoot. It didn't take long for our guy to get dry docked on the trick side pocket. Our guy's ball was frozen on the side rail so he slow rolled it, as to lag for the side, and it rolls about a quarter inch past the side pocket then, like a real golf putt, rolls back around the lip and falls in the pocket on the side near which it came.
Danny jumped up in the air, landed and screamed, "What it did?!!!"
Danny figures he has been trapped but refuses to quit. He thinks now that he knows the trick pocket that he can do the same thing. Wrong. The shot had to be rolled down the rail at an exact speed to fall off into the pocket and every time Danny tried it, no luck. He either hit it too hard and ended on the other side or never hit it far enough to work.
Danny stayed in town about a week practicing rolling balls toward that trick side pocket. When he thought he had it down he tried our guy again. Didn't like it then either.
