nysrep is correct in his understanding of the rules. If a club wants a specific kill zone used it must specify so. The aligator is a good example of a target which is often set so that both kill zones are open. (shooting from an elevated location at a broadside or slightly turned target.) From that position an argument can be made as to which is the safer shot to take. I've also seen the "lucky" shot hang by a thread in the top 10 or 11 ring when it was obviously not intended. The rule protects the choice of open shots when not specified while trusting to the integrity of the competitor in the event of a "lucky" near miss. In this event I will usually leave it to the competitor how they want the arrow scored. They can rightfully keep the points, which most will do, or they can take a five, which a few have done.
