Ross Porter's thoughts have prompted me to write re the format of your tournaments ABC and Pro-Am.
Ross included one fact which I had not been sure of, and that is the distance (hour and half-hour.) Perhaps you might include this in the header for us colonials. (Point taken - Ed.)
I agree that handicapping is not the answer to providing a fair day's play for one and all, and would like to propose a scenario which we have tried successfully at State level, and which is also used for every major event at world level in another branch of cue sports.
This is the, "Double Elimination," draw, and I have included a copy courtesy of John Lewis, Billiards Congress of America, which I hope you can squeeze into print.
I will explain the benefits first;-
A normal knock out draw - with a Mirror Image draw going the opposite way.
Normal draw goes to the right and the losers draw goes to the left. If you lose in the main draw, up to whatever point the organiser decides, you are then transferred to the losers side, if you lose there then you're out.
I believe that this is the best system for all cue sports. However there are disadvantages, some of which can be overcome.
A short cut to partially solve these, is to have two lives only to the last 8 or last 4. So either the quarters or semis are knockout. This saves time and these players are already in the money. Of course, organisers have to become familiar with the system to use it to the best effect, but it is not difficult. I have draws for any number of players up to 64. As is the case with a standard draw, you can use a 32 draw for, say, 20 players, creating the byes is a little different.
