    I won't say that I considered my decision a coin toss but my
    confidence level was only around 55 to 60%. I certainly felt
    the decision was marginal.
    I was completely right about the marginality but chose the
    wrong side of the border -- my take was very slightly wrong.

    BTW, this take was my only cube error in this game (but not my only cube error in the match [which I won]).
