LS John & Chapo;
I check out some official rules of golf, and like pool there are different organizations and thus their rules will probably vary and also their rule layout format. USGA has a table of contents in which you can click on any rule or item and it directs you there. This is extremely nice.
PGA rules seems quite simplistic and they utilize many diagrams.
To answer how to make a global one fits all OP set of rules, it is not possible, for each entity wants their own rules and must have their own rules to become relevant.
But, it is possible to develop rules that are highly technically advanced above all others, and thus they would be the standard that all others are judged by.
Rules are in two formats; 1. The Game Rule; usually short and specific in pointing out how that specific game is played. 2. The General Rules; these go into detail specifics of each rule, plus all other aspects of how to play pool. General rules of today are not technically advanced. There is not one single written rule today that depicts the more highly advanced pocket billiard scenarios as we see occur quite frequently in OP.
I feel modern day 'General Rules', (not game rule that we have), need to depict these highly technically scenarios. And since they do not then it thus lowers the standard of how OP is played, and the standard that OP players play by.
A modern day set of rules needs advanced technical written 'general rules', plus diagrams and videos that compliment and further depicts these more highly technical scenarios, for comprehension.
On another point which I have become alarmingly aware of is that OP rules do not have player's proper procedure defined 'at all'. This is amazing for there is so much interaction with the balls and players! For instance; which player is responsible for putting and pulling out their balls into their collective area, who spots balls-the out going player, who puts up and removes their coins- the offending player, is the neutral ball spotted or can a scored ball be spotted in its place-the neutral ball should be spotted, when can a player take a break from play, we see abuses of these proper procedures all the time, well they are 'not' defined, thus the abuse is accepted.
This can all be accomplished! And this is not saying anything against our OP.org game rules, but WPA general rules are 'not' technically advanced enough nor can they be specific geared towards OP. for they cover all games under their domain, which OP game is not, but it will be someday for it is getting popular in Europe.
Steve has mentioned a few times that our OP.org rules are due for some upgrades, but all in all they have held up pretty well over the 2 years I have been a member in which many rule questions have come up. Thank goodness Steve had the foresight to add some clarity to the rules, otherwise there would be much more problems occurring.
'General Rules' are always changing depending on who is in power, and since WPA General Rules govern over our OP rules then our OP rules are subject to change, and unless OP.org develops their own 'General Rules' there can be no secure future going on into perpetuity.
Sorry this is so long, but I think this endeavor of developing your own 'General Rules' is such a highly credible, honorable, and is of such a historical significant nature that it is worthy of such length. With due respect, Sincerely, Whitey
