Many years ago when I was trying to win all the little bar tournaments I could find, one particular 8-ball tournament comes to mind. It was in a rough place called the Purple Plum. For the win I had to kick three rails on the 8-ball, TWICE! My opponent had 5 or 6 balls remaining, and I tried to squeeze the 8 by one of them and barely missed. The 8 hit the corner pocket tip and bounced about 2 inches out and directly in front of the pocket, blocking one of his balls that was about a diamond out from the pocket.
The guy missed his shot and hooked me behind a ball where I had no easy kick at the 8. So I called a 3-railer, and immediately three or four locals came over to watch the shot. My opponent said If I hit either rail next to the 8 I lose. And his buddies stood right there to make sure. I shot it so softly that if I did happen to hit the rail before the 8 I'd hopefully not make it. The cue ball went exactly 3 rails and then barely touched the 8, rolling it right up to the edge of the slate. Luckily we weren't playing league rules in this place -- strictly old-school bar rules, so no ball in hand.
Well, the guy misses again and hooks me again where all I have is another 3-rail path to the 8. And once again everybody stood close to make sure I didn't cheat by barely touching another rail or corner pocket facing before the 8. I shot shot again, perfectly going 3 rails and barely touching the 8, clean in the middle, and it rolled over and dropped into the pocket.
I guess they were more amazed than mad, so I was lucky to win the $80 pot without a fight. Two hour hours later, after stuffing another couple hundred dollars into my pocket via ring game style, 9-ball, 5 players, $2 a ball on the 5-7-9, my buddy (playing on the table next to mine) accidently poked a girl's behind with the butt of his cue while breaking. This of course got her boyfriend up and over into my friend's face.
After everything settled down, my buddy stayed clear of the tables and just sat and watched the ring game. About 20 minutes later he said he'd heard a couple of guys talking about getting their money back. And they weren't planning to do it on the pool table! I gave my keys to my buddy, told him to start the truck and I'd be right out. Three or games go by where I gladly make sure to toss my $6 dollars out each time for not making any money balls, then I ask the guys in the game what they're drinking, lean the bar cue against the jukebox and start for the bar. I walk straight passed the bar and hit the front door. Haven't been back since then. And my buddy, the one that had the truck ready, laughed when I jumped in. As we were going down the road he confessed to poking that girl on purpose. He said her boyfriend was gathering up a few buddies, not to take my money, but to jump him for messing with that girl! Anyway, that buddy of mine just passed away a few months ago. So this story is a good memorial to him. Sorry if I went too far off topic. EVERY BAR ROOM HAS IT'S OWN RULES, though I think today many players have adopted BCA or VNEA rules in most bars.
