Match Play. Double Match Point. How should Red play 64?

This all about connectivity. 16/6 leaves the rear checkers isolated.

20/16, 20/14 attempts to solve the problems of the rear checkers with only a small risk. It is the best play.

16/6 and 16/10, 13/9 (which you may not have considered) are both errors.
