Match Play. Double Match Point. How should Red play 66?
It is important in positions like this to keep the 8-pt as a landing point for the other checkers as they make their way around the board. Therefore 8/2(2), 7/1(2)* is too committal.
The only two real choices are 13/7(2), 13/1* and 13/1(2)*. XG has a mild preference for 13/1(2)*, building a second home-board point and leaving only eight return shots. Every other move is a bad error or worse.
