    Attacking with 13/1*(2) is the wrong idea here; this is a golden
    opportunity to escape our back checkers. But do we run all the way
    with 22/10(2) or do we make the bar point with 22/16(2) 13/7(2)?
    I opted to make the bar point, but XG says that's a whopper. The
    trouble is that 22/16(2) 13/7(2) doesn't do all that good a job of
    containing O's straggler, and still leaves us with the task of
    clearing our 16pt later on.
