Here is data for opening 41 at all four scores (money, dmp, save, go):

    [S $23 U31 T46 W54] ~46*10*5
    [S $6 U52] /92*5
    [S $8] <282
    [S $22] ^25

    d[$ S2 U18] /69*31
    d[$ S3 U26] 36*5
    d[$ 3] "<101

    s[S $9 U27] /15*9
    s[S $21] ^5
    s[S $10 U25] "<77*5

    g[$ S8 T58 W59] /38*5
    g[$ S9] <28
    g[$ S8] "<101
    g[$ S2] ^46

Key: S = Split (24/23 13/9), $ = Slot (13/9 6/5), U = Up (24/23 24/20), T = sTack/Tower (13/8), W = Wild (24/20 6/5). Margins are in thousandths. Before brackets, d = dmp, s = save, g = go; else assume money. After brackets is a bot symbol (~ Snowie, / GnuBG, < XG1 3-ply, "< XG2 3-ply, ^ XG 4-ply) and the number of trials in thousands, rounded down (an asterisk is a repeater, not necessary after the final number).

For example, "s[S $9 U27] /15*9" means that at (gammon) save, S is best and $ is -.009 in a GnuBG rollout of 15000+ trials, and U is -.027 after 9000+ trials.

The XG1 3-ply data for 41-s exists, but I don't have it yet.
