Fwiffo: my literal understanding of your initial translation (23 Jan 19:00) is that a piece can be captured by a single enemy against a central square, as some reconstructions have it. This I find undesirable. Your latter correction (23 Jan, 19:06) makes it sound like a clarification rather than a rule, and brings Brain King's rules more into line with Linnaeus's text.

As for draws by repetition, I would be happy enough if a draw was mutually agreed by the players, rather than enforced by the rules. If an unsportsmanlike Swede attempts to win by attrition, making repetitive attacks while refusing the offer of a draw, it's simple enough on this site not to play against him (or her) in future.
