    At first, I thought that this position had to do with giving O bad
    fives to play. That's not irrelevant, but after looking at the
    position more, I think it's that 13/10 12/10 just gives better
    coverage of the board. If O rolls something nondescript like 32
    next, XG still assesses O's position as being significantly worse
    if X has played 13/10 12/10.
