    X is ahead in the race and if he anchors, then his 6 is a little
    awkward. Nevertheless, the XG rollout indicates that anything
    besides 24/22 8/2 is a whopper or worse. This is an example
    of the adage, "When defending, make defensive plays." X is an
    underdog here and O has some serious attacking potential, so
    X can't afford to be leaving blots around for O to hit.
