Cube Error/Answer

It's Redouble/Drop.   I was Blue and didn't redouble.  The problem is that I play "too much" backgammon for money, and for money this would be a terrible redouble, but in a match at this score, it's not even a take.  From Blue's perspective, if he loses 2 points he is at 1away/4away Crawford and his Match Equity is only about 18 percent, so he doesn't have much to lose by turning that cube.
