Match Play. 2-2 to 5. Should Red redouble? If redoubled, should White take?

Trice’s Formula 62 will give you the correct answer to this problem, but Reichert’s formula will not. Simply looking at the pip count is insufficient in positions like this one – you need a formula.

This is a redouble (just) and a trivial take. For money it would be a blunder to redouble here but the cube has no value to White and Red is within his doubling window so he should redouble
