AbigailII: Since when does a rule have to be written for it to be a rule? Some rule are conceptual ones, perfectly capable of being held in your head without requiring you to see them in print or on a web page. It would be better, as BBW says, if Fencer made the rule visible, but it is available through logic.

So. Please refute that logic relating the existence of the bug to the existence of the rule - if you can.
