In my defense, I originally published this as a throwaway on my Shortform (it's sort of like LessWrong's take on Twitter), but one of the admins wanted me to repost it as a main post. I agree that ideally I would have wanted to playtest this more before drawing attention to it.

That being said, I do suspect that these rules are probably pretty close to achieving the effect I wanted to achieve- the main doubt I have is whether the king's moves work, or if they need to be adjusted to get the balance right, but even there, there's a good chance that it works. I will make sure to update the article when I get a chance to test it out.
