    X on roll, cube action

    X has 11 checkers in the zone and has escaped one of his back
    checkers. He has a massive lead in the pip count. On the other
    hand, he has only a two-point board, with one of his points
    being the 2pt. O is anchored and has good chances of making a
    second anchor, and she has made her own 5pt. This is an easy
    take for O, but I thought it was a good double for X. In practice
    I think there are many who will pass this cube, but XG says it's
    far from a double.
