    I found the below position tricky -- so tricky that I in fact got it wrong. Here, the DMP play is completely obvious.
    But should we deliberately sacrifice wins by removing four checkers
    in the hope of a gammon?
    I didn't think so but I was wrong.
    It is very common when bearing off against contact that you
    deliberately take risks and leave your position awkward in order
    to bear off faster and increase your gammons.
    Assuming that the DMP rule is still helpful, I think that the proviso
    "when not bearing off against contact" needs to be applied.

    Perhaps it might be hard to tell, once you've seen the answer.
    But do you think you would correctly make the greedy play or would you make the same mistake I did?

    I think I would have made the greedy play. I would have seen
    that the greedy play would get me off in roughly five more rolls
    and so the gammon race was close. Based on experience, I would
    have figured that going for the gammon was indicated.
