Nackgammon Opening 52


I thought I'd posted the data but evidently not; sorry. Here goes:

    [Q z10 S16 Z19] ~10
    [Q z5 Z9 S15 R34 U57 C58] /62**46 15 5
    [Q Z11 z13 S24 R36 U50] <62***31 15

Key: Q = (Quadruple split, 23/18 24/22), Z = (reverse split, 13/8 24/22), z = alt reverse split (13/8 23/21, S = 23/18 13/11), R = Run (23/16), U = Up (23/18 23/21), C = Cross (23/18 8/6).

Margins are in thousandths. After the brackets is a bot symbol (~ Snowie, / GnuBG, < XG1 3-ply) and the number of trials in thousands, rounded down (an asterisk repeats, not necessary after the final number).

For example, "[Q Z11 z13 S24 R36 U50] <62***31 15" means that Q is best, Z is -.011, z is -.013 and S is -.024 in an XG 3-ply rollout of 62000+ trials, R is -.036 after 31000+ trials, and U is -.050 after 15000+ trials.

Below are after-positions of the best plays, ranked by agg (aggregate bot value):
