When is U correct?

In Response To: When is U correct? (David)

Anybody have a summary of when U is correct on the 1st roll?

In thread context, I'll assume that you are referring specifically to 43U and I can only think that you mean the reply roll (what is commonly referred to as the second roll) rather than the opening roll.

Neil's answer for money (replies to 21$, 41$, 51S, and 61P) is correct. For some of those positions, 43U (i.e., 43 played Up, 24/21 24/20) is also best at other scores. The list below shows when xx-43U is best [m = money, d = dmp, s = (gammon) save] according to GnuBG rollouts (and there are no dissenting ROs from other bots).

21$-43U: mds
41$-43U: mds
51S-43U: m (d -.001, s is -.003)
61P-43U: md (s is -.004)

I know of no rollout for 43U-43 at gammon save, but X probably beats U.
