    The all-out blitzing play is to hit and make the 2pt. On the other
    hand, it leaves five blots around the board, and loses more often
    compared to the DMP play of 21/9*(2). Does the all-out blitz win
    enough extra gammons? According to the rollout below, the answer
    is yes. O will be twice up, and even if she enters with 41 or 54,
    it will still be a roughly even game, so the upside outweighs the
    downside.
