    I knew that at 7a4a, I should be quick with the recube, but it didn't
    occur to me that I had a lot of market losers here. It's not so much
    that X is threatening to roll something good, as O is threatening to
    roll something bad. For example, if X rolls something like 53 and
    plays 21/13, then XG says that O has to pass if she rolls 5x (or 61
    or 64). Still seems surprising to me.
