I am unfamiliar with the word campmate. Did you coin it or get it from someplace else?
Since your rules still say "No Impasse(=Jishogi)", I should point out that there is a difference between a rule and a consequence of your rules. For example, Metamorphin' Fusion Chess has rules that allow players to promote simple pieces and to split apart compound pieces, and one consequence of these rules is that reproduction of pieces is possible. Generally, a rule should be written out as a complete sentence, and it should concern itself with specific actions a player may or may not take. A consequence of the rules is not itself a rule, and to avoid confusion, consequences of the rules should be covered in the Notes section, not in the Rules section.
