It's not a blitz cube however it is a blitz position.

Eleven checkers in the zone, a three-point board, a 20+ pip lead,
and the back checkers mostly escaped---these factors would often
be enough to justify a double. But O has a strong board, and has
a good chance of anchoring and ending the blitz. According to the
rollout below, it's not a double yet, despite the high gammon win rate.

Yeah, this looks like a blitz, or like it could be. Only a single direct
shot at the blot, so not as overwhelming as they are sometimes. Only 33
points on O's head, and the numbers that hit loose offer a bit of
counterplay, as does the three blots strewn around the board.

Take seems clear. What are the market losers? Making a fourth homeboard
point followed by a dance, but that appears shy of the 25% usually
needed. So I'll hold this one.
