Unlimited Games. Should Blue redouble? If redoubled, should White take?

The question here is how much allowance to make for White’s very poor structure. I would add one pip for White’s virtually empty 5- and 4-pts and then another pip (perhaps 1.5) for the extra checkers on the 3-pt.

If you then use Trice’s formula you get redouble/take. XG agrees. Not redoubling is an error but only just.
