    It's pretty easy to judge that if X hits then he almost always loses
    his market, but I was concerned that if I danced then I would be in
    big trouble. I'm almost 40 pips down, after all. But it's not as bad
    as I thought. O might not be able to clean up her blot, and still has
    quite a lot of work to do even if she does clean up the blot. Once one
    sees that, it becomes a double per O'Hagan's Law.
