2020 - Position 10

XGID=-BBB-CB---A-b-a--bBcdba--A:1:1:1:00:1:2:0:9:10

Match Play. Red trails 1-2 to 9. Should Red redouble? If redoubled, should White take?

In a money game this would be a very poor redouble. However, the match score dominates the decision in this position.

A gammon with the cube on 4 gives Red the match exactly and that efficiency is enough to make this a very strong redouble. It is a trivial take of course, but not redoubling here is a blunder.
