• The kind of situation badgolferman hates

    From Tim Chow@21:1/5 to All on Sun Jul 31 08:27:06 2022
    Haven't heard from badgolferman in a while, but he used to say
    that he hated getting into positions where he has trouble getting
    off his bar-point anchor safely. In the position below, do you pay now?

    Sometimes when you opt to pay later you don't have to pay at all. This
    might be one of them. I'll clear the eight point.

    O has a blot in her board, and X is ahead in the pip count;
    these suggest that X should perhaps pay now. On the other
    hand, O is stripped and may have to volunteer a shot next
    turn, and X has a play that covers the blot in his own board.

    If the blot in our own inner board was lifted or covered it would be correct to run off the anchor now. If the opponent had a spare checker to play in his outfield it would be correct to pay now.
