Alert! Watch out for the flipped board!

I'm a little surprised that this seems to be a clear take.

The score (after 0 games) is: Blue 10, White 9 (match to 21 points)

Move number 2: Blue on roll, cube decision?

Blue	134
White	147
Position ID: 4NvBCUCLncEBKA Match ID: MAGgAqAASAAE

• Blue doubles

Cube decision
4-ply cubeless equity		+0.608	(Money: +0.600)
	0.643 0.393 0.006 - 0.357 0.080 0.003
Cubeful equities:
1.	Double, take	+0.907
2.	Double, pass	+1.000	+0.093
3.	No double	+0.713	-0.194
Proper cube action:		Double, take
