I agree with Stick, on the best play (24/20 8/7), on his Nactation (which is transferred to the title of this post and caption above), and his analysis of both.
It is a particularly effective ploy to slot in front of an advanced anchor even when splitting the back checkers, as the illustrated reference positions in this post (discovered by Paul W. and I in our book research) will help demonstrate.
In the standard starting position of backgammon, opening 64Z, 63Z and 62Z (reverse splits -- splitting with the small number and coming down / slotting with the 6) are blunders of -.07, -.06 and -.09, respectively.
However, if you modify the starting position so that White has an advanced anchor (her 21pt or 20pt) instead of her usual 24pt anchor, the same 64Z, 63Z and 62Z become strong, balanced moves. Indeed, with the help of 3 or 2 duplication, Z is clearly the best play in the three examples below.
The positions reached after playing 41B above and playing 64Z in the first position below are similar. The difference is that White has brought down 65 and two of Blue's 6pt spares have made his 5pt.
