51S21U better as 51S21 $

In Response To: 51S21U better as 51S21 $ (Andreas)

Acc. Stick's RO page Snowie sees U better by a hair and GnuBG $ better by a hair.

Are there reasons to think U is best?

Nack: If rollout support counts, combined results for the three bots (as I listed in an earlier post, though not in a column) produce

Snowie .. [U $14...] 20k
GnuBG .. [$ U3... ] 92k 46kU
XG 3-ply [U $12...] 36k

The Snowie rollout on Stick's site is actually reporting [U $10] for the live cube equity margin. It's annoying, but for all Snowie html exports you have to look at the fifth line (or so) under each listed play to find the live cube equities, in this case -.175 and -.185, respectively. (I extended this rollout to 20k and the margin increased from 10 to 14, as reported above.)

The primary output numbers -.163 and -.165 are the (no live cube) cubeful equities, a result of the cubeless equities of -.117 and -.121 adjusted by a Janowski formula. (Empirically, I've discovered a rough 1.4 correlation ratio for early game moves.)

The Gnu rollout on Stick's site is [$ U1.4 ...] 46k. He has another 46k rollout of $ by itself (different seed) yielding a higher equity; averaging that in gave me the [$ U3] margin listed above.
