One point of any league system is to help players learn standardized rules
Actually, a pic of the page in this case would be fair use, IMNSHO. The
rules specifically address frozen ball situations. What Byrne said does apply to the current rules.
As for making up special rule sets for leagues, I think that's a horrible mistake. One point of playing in competition is learn the rules of the game. I think League Operators who wander off into the weeds of "dumbed-down rules" do their players a disservice.
Probably the most succinct (and best stated) post I've read on this "customized rules" topic in a very long time. It amazes me every time I hear how a certain league chose not to honor a long-standing, time-honored, tried/tested/true world standardized rule because the league coordinator "thinks" the rule is either unenforceable, confusing (which is most likely because he/she him/herself is not understanding the rule), or will result in "arguments" amongst the players.
Three years prior to its closing, when I took over running the Boston Billiards league at the now-closed/-defunct Danbury, CT branch, I thought their "customized rule" about frozen balls having to be shot at with a 45-degree (or greater) elevated cue, and then the cue ball having to be verified that it did not travel into the space of the object ball, was the most ludicrous "rule customization" I ever heard. Especially when: 1.) World Standardized rules specifically state the shooter can shoot through the frozen ball situation using a normal stroke, and 2.) this "rule customization" actually ignores the fact that a serious foul can occur when playing that shot with the highly elevated cue -- that the shooter, focusing on making sure the cue ball doesn't travel into the space formerly occupied by the object ball, can either bounce or draw the cue ball onto the ferrule of the cue, which head-spinningly enough, wasn't a foul by their standards! (They considered it an "accident in the course of observing the 'no object ball zone entry' rule." <shakes head>)
The first thing I did was to toss this, and other silly rule customizations, out the front door skidding on the seat of their pants. I believed then as Bob states; one of the points of any league is to learn the rules of the game, as written in any standardized rule book. During each league session kickoff meeting with all the players, I had an easel with diagrams of various shot situations, some legal shots, some fouls, and even demonstrated some on a nearby table. I made sure all players knew the rules as written. And I had the BCA rule book with me at all times, in addition to the printed copy of the league rules. Every time a new player joined during the short open window of the start of the league session, I did the same presentation to him/her.
After Boston Billiards decided to close the Danbury, CT branch, I had several ex-Boston Billiard league players come to me, after they'd played in other leagues for a while, stating how screwed-up that particular league's rules are (giving me examples, resulting in both of us shaking our heads and laughing), and how they missed playing in what they all-too-kindly called "a real league with real rules." And this is the legacy that, as a ex-league coordinator, I'm proud of the most. I would think that's something league coordinators strive for, no?
