• Now I know just what TG really means

    From pepstein5@gmail.com@21:1/5 to All on Sat Dec 11 11:00:51 2021
    I don't know what a rollout would say but I agreed OTB with XG's analysis verdict of marginally TG despite there being a few crushing market gainers. Consistent with TG, I took two checkers off when I rolled a 32 but XG
    would have played safe.
    XG then played 18/7. I then correctly cashed and here rolling would
    have been about a 0.05 error.
    Good cube play from me but the checkerplay was apparently too greedy.

    You take two checkers off and are hit and lose just over one game on average. Let's call it 3%. You play two off the six point you obviously win 100% of the time. 97% compared to 100% so do you think taking two off wins you 6% more gammons?
