"Bot content" is a slight exaggeration, because I am going by my memory of truncs (truncated rollouts) that I have misplaced. As I recall, the ranking of plays (best play first) for each position is as shown below. (I'm fuzzy on the exact order of the weaker plays in each row, but I'm fairly confident about the top plays.)

    21S-41K-54>-44 [k K P B C M R]
    21S-41K-53>-44 [B P M R]
    21S-41K-52>-44 [P B k M R]

    k = 13/5*/1 8/4* or 13/5*/1 8/2*
    K = 13/5* 8/4*(2)
    P = 13/5*(2)
    B = 24/20(2) 13/9(2)
    M = 24/20 13/5*/1
    R = 24/16(2)
    C = 24/20(2) 8/4*(2)

I find the first position especially interesting, but that there is a different best play for all three positions is also of intrigue.

Of note, too is the juxtaposition of B and P in the second and third positions; the 9pt directly blocks Opp's 22pt blot but not her 23pt blot. (P is ahead of B in the first position as well, but I think in that case the two plays were close to each other unlike in the other two positions. ) For reference, the positions are diagrammed below, with (marginless) nacbracs encaptioned. "mt" stands for "memory of trunc"!
