    12 immediate sequences you dance and O hits, giving her great prospects for a gammon. Might as well double for those and a few other gammons to come. If you win, you'd rather win your gammons on the 2 cube to bring you to an even match. I think it's a
    double and take.

    X has 16 dancing rolls, which leave him in big trouble---for money,
    O would be too good to redouble, according to XG. Even though almost
    every entering roll is excellent for X, and doubling kills O's gammons,
    I did not double here. XG says that this missed double is unspeakably
    bad. Even in terms of match-winning chances, the loss is tangible, from
    about 23% to about 19%.
