How about trying to regulate the use of destructive conventions , by changes to the scoring rules of the game of Bridge , rather than by regulations imposed by organizations? I mean , for example change the scoring of the game so that 1. If a pair goes down 4 or more tricks (maybe 3 tricks on the 1 level) , the contract is automatically considered doubled. Or : 2. If a pair reaches a suit contract with 5 or less trumps between them, and then go down , the penalty is automatically doubled. I realize that better , or more precise suggestions may be made, I was just trying to show where I am aiming. It seems to me that once such scoring changes are applied , the "anything goes" crowd can be free to design systems quite freely, because the very need they will have to arrive to reasonable contracts , will prevent them to use too much of destructiveness . On the other hand they will be free to do whatever they like within the rules of the game. The various federations will no longer have to devote much effort to system regulation, because the bizzare , destructive, hard to defend against systems will become unplayable. The (Many) "let us play normal bridge" players , will be able to play the game as they love it , because the scoring changes will have only a little effect on them. So, does anybody think there is any merit in this?
