In Response To: New(?) backgammon puzzle (Nack Ballard)

Below is a solution with two additional cube turns (requiring 6 more pips). As before, both players (double)/redouble every turn and roll 21.

White passes the cube when Blue (with a lone 4pt checker) turns it to 512.

[I'll leave it as an exercise for the reader to figure out why it does not work if Blue starts with a formation of 655 or 664 instead of 952 (as diagrammed).]

This position is reachable in backgammon, though it is easier to reach in hypergammon. :)

Blue on roll, cube action?
