The reason I thought a hyphen was needed is that they are pages about chess variants, rather than variant pages about chess. And that associativity of adjectives and nouns by default is right to left. "Red rule book" would mean a rule book that is red, not a book about red rules. (Unlike adverbs, which automatically associate with the adjective, such as "extremely large page" means a page that is extremely large, because a 'large page' can be 'extreme', but cannot be 'extremely'.)
