    In some ways, this position follows the same theme as the previous
    position ("Hit?") in that the seemingly inflexible stacking-up play
    of bar/20 8/6 is XG's favorite by far. The race is even and X would
    like to run his third checker back at the earliest opportunity. After
    bar/20, playing 13/11 or 6/4 volunteers a shot for insufficient
    compensation.
