Hi Fred, In my experience, cramps in a marathon can only be self inflicted:). Besides, causing cramps in the opps. legs is par for the course in bridge -- indeed, there is a reason why a plethora of preempts exist. As Free noted, competition at the highest echelons of any game can hardly be expected to be for pure "fun". Banning conventions that rattle one’s cage is like participating in a marathon where’s there is cap on participants whose VO2 max exceeds one’s own. A win in such an event would only be a pyrrhic one. While I do see the need for some regulation, I don't think that arbitrarily banning conventions that run against the grain of one's aesthitics is healthy for bridge in the long run. Atul
