In Response To: Opening 21 at GS XG2 4 ply 46k (neilkaz)

Thanks for the "^46 rollout, Neil. Here is data for opening 21 at (gammon) save:

    s[$ S2] /61
    s[$ S1 U39] <20*5
    s[S $2] ^67
    s[$ S1] "<101
    s[$ S2] "^46

Key: $ = Slot (13/11 6/5), S = Split (24/23 13/11), U = Up (24/21). Margins are in thousandths. Before brackets, s = save. After brackets is a bot symbol ( / GnuBG, < XG1 3-ply, ^ XG1 4-ply, "< = XG2 3-ply, "^ XG2 4-ply) and the number of trials in thousands, rounded down (an asterisk repeats a number).

For example, s[$ S1 U39] <20*5 means that at (gammon) save, $ is best and S is -.001 in an XG1 3-ply rollout of 20000+ trials, and U is -.039 after 5000+ trials.
