In Response To: 54-s ^15 RO (Stick)

Too lazy to combine/edit the rollouts this morning.

Thanks for using the same seed. In other words,

54 s[S R6] <10 20
63 s[S R3] <20

For completeness, here is all of the 54-s and 63-s data (accumulated so far) in the same post:

Opening 54
s[S R17 D45] /36*5
s[S R10 D24] <^e
s[S R6] <10 20
s[S=R] ^15

Opening 63
s[S R3] /84
s[S R3] <20
s[S R6] ^12
s[S R1] "<101

Key: S = Split(-and-down), R = Run, D = Down. Margins are in thousandths. Before brackets, s = save. After brackets is a bot symbol ( / GnuBG, <^e XG1 7-ply eval-only, < XG1 3-ply, "< XG2 3-ply, ^ XG1 4-ply) and the number of trials in thousands (rounded down).

For example, for opening 63 "s[S R3] /84" means that at (gammon) save, S is best and R is -.003 after 84000+ trials.

For 63, we also have s[R=S] <5 from David, but I don't know if that is a subset of your rollout or if it is independent. If the latter, it nudges the XG1 3-ply average down to s[S R2] <25.

To address Philip's point: Overall, the data suggests that at (gammon) save, the absolute equity/value of opening 54S is about .007 higher than opening 63S. Curiously, the 4-ply rollouts (15k and 12k) in isolation suggest the opposite; ah, the whims of variance.
