Thanks, Claude, for the ^46 rollout. Here is data for 43Z-43:

[H=X K28] ~31*5
[H X9 K35] /15*5
[H X3 K35] <62*15
[H X12] ^46

d[H X4] /5
s[X K25] /5 (where is H?)
g[H K36] /5

Key: H = Hit (13/10 8/4*), X = hit-and-split (24/21 8/4*), K = Kill (8/4*/1*). Error sizes are in thousandths.

Before the brackets, d = dmp, s = (gammon) save, g = (gammon) go; else assume money. After the brackets is a bot symbol (~ Snowie, / GnuBG, < XG 3-ply, ^ XG 4-ply) and the number of trials in thousands, rounded down. (An asterisk repeats a number.)

For example, "[H X3 K35] <62*15" means that H is best and X is -.003 in an XG 3-ply rollout of 62000+ trials, and K is -.035 after 15000+ trials.

The data for 43Z-43 is very similar to that of 43Z-32. The difference in resulting 8pt/6pt distribution seems to have little net impact.

A bigger (though still small) effect on H/X occurs when you move Opp's (more exposed) 9pt builder to her 11pt. Let's compare Opp's 32S and 43Z openers, and the 32 and 43 replies, reducing each money result to a single agg (bot aggregate value):

43Z-43 [H X6 K33]..... 43Z-32 [H X7 K44]
32S-43 [H X12 K41]... 32S-32 [H X16 K42]

These four positions are illustrated below in the same 2 x 2 orientation, with their nacbracs encaptioned:

43Z-43 [H X6 K33]

43Z-32 [H X7 K44]

32S-43 [H X12 K41]

32S-32 [H X16 K42]
