As Stick is probably implying, the score makes a big difference to the checker play decision here. For money, E (Each, bar/20(2) 6/1*(2)) is clearly best while R (Run, bar/15(2)) is likely a blunder (using the -.06 threshold of the Ballard/Weaver error scale); whereas, at the –6–13 score, E and R are likely tied (i.e., within .01).

It is also worth noting that White's last move of K (Kill, 13/7 6/1*) might well have been a blunder for money, whereas at the –13–6 score K was clearly best. (The R/K breakeven seems to be at –13–8.)
