XG says 8/6 8/2, and it is .037 better than 13/7 8/6, .047 better than 13/7 9/7
From Matt's Note:
My proposed play of slotting the deuce seems like the right idea here. We need to make the 2pt eventually and getting hit is not costly, and at the same time we keep pressure on the 10pt blot in case we roll a 3 next time. To me, it is hard to see but quite understandable.
