    This one shouldn't have been so hard but I managed to mess it up OTB
    anyway. After 6/4*, stepping up to the edge of the five-prime is
    more urgent than covering the blot on the 4pt. If X could already
    escape the straggler with a 6, it would be a different story (see
    variant below).
