    Usually, if you have to run off one of your backgame anchors,
    you run off the front, in order to maintain more contact. But
    here, X is hoping to get a shot right away, and needs to maintain
    contact with both of O's outfield points. A deuce-point game
    is a less promising plan in this position.
