• XG is lucky -- it can't hear when people are screaming at it.

    From pepstein5@gmail.com@21:1/5 to All on Wed Dec 8 12:10:52 2021
    XG played this roll 13/10 8/4
    It next rolled a 33 and I entered one checker on the 6.
    It then played 10/9 3/1
    I then danced.
    XG then rolled 22.
    I then hit XG's blot to get a near-equal position and
    won from there.

    If XG was the captain of a chouette team, its teammates
    might well be screaming at it because its problems do
    seem largely self-inflicted.
    In particular, I can't imagine a strong human playing
    13/10 8/4 from the original position, which busts to 33
    rather than 13/6.
    An intermediate human is well-trained to look for root
    numbers from the original position and would anticipate the 33.

    If I were playing X in the box, I might very well play 13/10
    8/4 because I would be focused on trying to clear the high
    points in my board, and I might overlook that 33 cracks my
    board (even if I noticed it, I wouldn't necessarily think it
    was a terrible roll, because it wouldn't blot and it would
    start clearing my high points). But as captain of a
    consulting chouette, I would certainly play 13/6 if the
    team wanted it.

    Surely you would notice the 33 cracking parlay. (I noticed this before XG rolled it.)
    A sub-5 player simply has to notice root numbers!
    33 is actually not a particularly bad roll (as you correctly suggest) -- it loses something like 0.02
    if I remember rightly. Appearances can be deceptive.
    XG also gave itself the anti-joker 22 (and then rolled it!) which could maybe have been avoided
    by playing 10/8 instead of 10/9 but I'm sure there were reasons for this too. (Alternatives might give
    more anti-jokers).

    Extraordinarily lucky comeback for me.
    Pity this didn't happen with anything real at stake.
    Also, I messed up the post-hit phase. I couldn't find the correct doubling point.
    In fact, I still don't know the correct doubling point.
    So that's my follow-up question.
    As per my original post. I hit XG's blot on the 9 point while XG had a four point board -- this created a game
    where my winning chances were 50/50 but XG gets more gammons.
    If things go well for me after this hit, when should I double?
    (I doubled too early to give myself a poor PR for the game but it was still miles away from a beaver.)

    Thank you.
