Match Play. Blue trails 7-10 to 11. How should Blue play 65?

The easiest way to win both game and gammon is to separate the three White checkers on Blue’s 3-pt. The best way to do this is to let them out now by playing 8/2, 7/2 forcing White to play his fours and fives. With best play, which not necessarily that easy Blue wins 87% of the games and of those 19% are gammons.

Any move other than 8/2, 7/2 is a bad error and moves like 7/2, 7/1, killing a checker, are blunders.
