    X obviously has a massive positional advantage. He has a five-point
    board, while O has a bunch of semi-dead checkers and stripped points.
    At gammon go, X wants to maximize contact, and blots be damned.

    Since you say "at gammon go", I'm a bit surprised
    that you're not posting variantizations for DMP and money.

    Any rebuttal of the form "Why don't you do it yourself?"
    is answered by the fact that my only computer with XG on
    is busted. I know there are workarounds for that, but I'm lazy.

    Fair enough. Below is a money rollout. I don't think that a DMP
    rollout is necessary since 18/13 11/5 is not remotely close at DMP.

    O's structure is awful and an exchange of hits massively favors X. So,
    I'll provoke that with 18/7. Not sure if it's right, but also not sure
    if it is right for O to hit.
