  • How modest am I?

    From pepstein5@gmail.com@21:1/5 to All on Sat Jul 30 11:10:34 2022
    Here, I passed XG's double.
    But am I humbly and courageously confessing to an
    egregious backgammon error?
    Or am I shamelessly bragging about a truly excellent play?

    (The fact that XG should cube seems too obvious to be worth
    stating.)

    I think this is a take. XG's 8/6/5/4 formation is very strong and
    there is also a tenth checker (almost) in the zone, but you have
    only one checker back, and you have made your bar point. It does
    give me pause that you have another blot that could get picked
    up, but it's currently not subject to a direct shot.

    Yes, but quite a thin take. My drop cost me about 0.055.
    Good analysis.
