I played in a Sat night tourney here for several years until my fave pool hall became a sports bar! Anyway, it was a handicapped tourney and alternated 8 ball one week and 9 ball the next. TD kept records and adjusted handicaps. Strangers were rated high to prevent the obvious. Flip for the break and alternate after. Number of games in each player had to win was based on handicap. Double elimination, $10 buy in, no calcutta. We often had 30+ players and had a good payout with $ added from the bar. Tourney started at 7pm and was usually over by 11. I ran this tourney a few times when the TD couldn't make it. He had a shareware (I think) program on his laptop that did just about everything except handle arguments!
