Below is data for 65R-xxx-66. Replies in blue font are worse than -.02. Nacbracs in black denote XG1 or XG2 rollouts (in a few cases followed by those of GnuBG and Snowie). Nacbracs in red denote XG2 Roller++ evaluations.

For money, dmp and (gammon) save, Z is the main play, usually best or "tied." For money, P is best against 6-splits. As far as I know, D is clearly best only vs 22N, 33A, 43S and 43Z for money, and vs 22N and 33A at save.

At (gammon) go, play O against ace-splits or P against other splits. Against no split play D, except stay with Z when it is best for money by .045 or more (there might be a couple small exceptions).

Key: Z = 24/18 13/7(3) -- formerly nactated U or R assumptively; D = Down (13/7(4)); P = Point (13/1*(2) or 13/7*/1*(2); O = 13/7(2) 8/2*(2).

There are no AtS nacbracs above, but some specific data is listed here.

[David's choices are all either best or tied, except for 65R-51S-66D (-.03) and 65R-41S-66O (-.02 for money, though best at go).]
