    What's the DMP play? XG marginally favors the pedestrian 18/8 11/6(2)
    at DMP, but the bold slotting play 18/3 11/6 is its overwhelming
    preference for money. Closing the board would all but lock up the
    gammon, and even if O hits from the bar, her weak board means that X
    will usually not be too unhappy about getting hit.

    I'm not sure why we're bringing up DMP here but the difference in plays is .003 with the best play being 8, 6(2) which comes in third in your rollout.
