In Response To: Opening 64 RO "+46 (neilkaz)

Thanks for the "+ rollout, Neil. Here is data for opening 64:

[P S4 R5] ~46
[P S6 R5] /202*186
[P S8 R13] <130
[P S4 R10] <107^ (3-ply move, 4-ply cube)
[R=S P4] ^46
[S P2 R4] "+46

d[R S2 P21] /46*5

g[P S17] /11

s[R S7] /98
s[R S1] ^46

–2–p [S R3 P7 U31] <31*5

Key: P = Point (8/2 6/2), S = Split (24/18 13/9), R = Run (24/14), U = Up (24/18 24/20). Margins are in thousandths. Before brackets is a score, e.g., d = dmp, g = (gammon) go, s = (gammon) save; else assume money. After brackets is a bot symbol (~ Snowie, / GnuBG, < XG 3-ply, ^ XG 4-ply, "+ XG2 roller+) and the number of trials in thousands (rounded down (an asterisk repeats a number).

For example, "–2–p [S R3 P7 U31] <31*5" means that at the score of needs2 needs1 post-Crawford, S is best, R is -.003, and P is -.007 in a GnuBG rollout of 31000+ trials, and U is -.031 after 5000+ trials.
