Here is a position which meets my criteria. White gives up .03 by passing instead of taking. Blue gives up at least .26 by doubling, no matter what White does.

This can be extended to other cases, not just ridiculously lopsided positions where White has two on the bar. E.g.: what about -3, -8, when -3 is holding a 2-cube?

The score (after 0 games) is: White 3, Blue 5 (match to 7 points)

Move number 9: Blue on roll, cube decision?
