    I always play with the pip count turned off, and here it didn't register
    on my mind---and I didn't bother to check by counting---that this roll
    puts me ahead in the pip count, so that clearing the 18pt is thematic.

    What's more surprising to me, and what would make a more interesting
    puzzle, is the variant, where O's blot is on X's 3pt. Then PoH is very tempting, but XG still deems it a whopper.
