    This is a tricky one for sure. In fact, XG 3-ply plays 8/6 7/1,
    but the XG rollout below favors 18/10.

    No, it doesn't. Your move filter might but 3 ply doesn't.

    Stick

    We've been through this umpteen times before. When I say "XG 3-ply
    plays..." I mean that that's what it (more precisely "eXtremeGammon,"
    the default computer player, which plays at the 3-ply level) *plays*.
    Not what move happens to have the highest 3-ply evaluation if you
    run all moves through a 3-ply evaluation. If that were what I
    meant, that would be what I'd say. I meant "plays" so I said
    "plays." Try to pay attention next time.

    It's horrible to put it that way for people who wouldn't know what you mean.

    That should be "person" not "people". "People" is plural.
