[D 1001280] "<=46.......... (1.001 pass)

[This] is is a good reference position, I believe.

Agreed; right on the take/pass cusp. Nice find, Igor.
(It was originally posted here as the final diagram.)

Retro-puzzle: From the opening position, what is the fewest number of rolls that can be played perfectly (according to XGR++ evaluation) to reach this position? (White rolled/played last.)

You should provide a supporting sequence. Nactation is easier to understand, but traditional notation is gladly accepted. :)

I'll post my answer on Tuesday.
