65R-41W-53 (tech. four-score?)

This position is an example of a technical four-score position, as adjudged by a set of XG 3-ply 31k rollouts.

The most promising candidate I've come across for a technical four-score position in the first three rolls of the game is shown below. Granted, White's second roll play of 41W is not strongest but it's playable (about -.022, averaging Snowie and Gnu rollout results).

Technical Four-score Position?	162
65R-41W-53

Here are Snowie's truncated rollout results (money, dmp, save, go):

m[H P6 K18 R19 S37]
d[R S13 P14 H22 K34]
s[P R2 S13 H21 K59]
g[K H15 P51 R72 S94]

(For reference, I included S as a fifth play; it is somewhat competitive at dmp and save.)

Key: H = Hit (13/5*), R = Run (24/16), P = Point (8/3 6/3), K = Kill (8/5* 6/1*), S = Split (24/21 13/8).

Here are the four plays diagrammed, each (allegedly) best at a different score:

Blue played H (best for money?)

Blue played R (best at dmp?)

Blue played P (best at gammon save?)

Blue played K (best at gammon go?)

Anyone whose fancy is captured by this position and would like to do Gnu or XG rollouts AtS, your help is welcome :)
