Thanks for the RO, Neil.

Here is what we have so far for opening 43 at gammon save:

GnuBG .. s[Z U2.3 D4.4 S5.1] 46k
XG 3-ply s[U Z6 D10 S11] 5k
XG 4-ply s[Z S1 U9 D16] 10k

Key: S = Split (24/20 13/10, Z = reverse split (24/21 13/9), U = Up (24/21 24/20), D = Down (13/9 13/10).

Error sizes are in thousandths. After the brackets is the number of trials (in thousands, rounded down). For example, "s[U Z6 D10 S11] 5k" means that at gammon (s)ave, U is best, Z is -.006, D is -.010 and S is -.011, after 5000+ trials.

I hope to see the XG 3-ply and XG 4-ply extended, to help eliminate variance as a partial factor. The swing of .015 in the U/Z margin, and .020 in the U/S margin, is puzzling.
