DragonKing: That's a question which has to be answered by Fencer. Such a feature certainly would be desirable but the rules, especially for perpetual chasing, can be quite tricky. Anyway I don't think that it's an urgent matter on a turnbased site because first you can inform your opponent about the rules, and if that doesn't help then you can always message Fencer and ask him to take measures. That is if you know the rules ;) If you don't and you agree to a draw because you think the same rules as in western chess apply then it's too late ;)
