    Some of my biggest blunders arise because I play quickly by instinct
    instead of thinking through the position. Here I rejected 6/4(4)
    instinctively because of the huge ugly stack, and also because of
    an instinct that the 6pt is valuable. But dumping checkers to the 1pt
    and creating a gap on the 3pt in front of O's anchor is far worse.
    The result is highly inflexible, creating several immediate blotting
    rolls as well as long-term blotting danger.
