Match Play. 0-0 to 7. Should Blue redouble? If redoubled, should White take?

This is a massive double for Blue. He has four cover numbers and if he misses even a hit by White doesn’t necessarily win the game. White will hit 27% of the time in the next two-roll sequence but he only wins the game 24.5% of the time.

On an initial evaluation XG makes this an easy take but a rollout shows an equity of -0.999 so you can take or drop, and you will be correct! I would take against a stronger player and drop against a weaker one.
