Every sports discipline, every type of competition in each discipline should have its rules that takes into account every possibility. Even the start of a new World War (I'm sorry). Nothing, absolutely nothing and never, should be able to surprise the referees, competitors, organizers, spectators, sponsors. Oh, don't forget about the stakeholders. The results of EVERY sports rivalry must be clear and obvious to every interested individual! ()
If a situation wasn't included in rules and it occurs, it should be radically stated, described, decided and publicly announced. Here's an example: when the rules of golf were being made for the first time, it was difficult to imagine World War 2 and London bombings that took place in September 1940. But the bombings happened and created funnels, in golf fields too, among other places. That's when the leadership of one of London's golf clubs introduced a new rule: if the ball lands in a bomb funnel – the competitor is entitled to one extra hit. This rule stands up to this date, just in case (I'm sorry).
Nothing, even situations that seem the least probable, should be omitted. Even stupid behaviour of the athletes.
Next example from tennis. One day (I think it was the 1970s) a competitor showed up to a match with two rackets. He held one in his right hand and one in his left hand, and he wanted to play like that. The opponent protested, the referee protested and the athlete... The athlete took out the rules and showed them that there aren't any mentions about having to play with one racket only. And it was true! The rule was added.
A Vendetta match, Armfight, so two competitors of SIX rounds. Six rounds, exactly six.
