Move the three runners into the home board and prepare to bear off.  13/3 11/6 10/5

Seems like a next to me, but I don't want to be presumptious my first go at facilitating.  I'll check back this evening and  move it along if there's consensus.

I don't see anything better to do, so I'm in agreement.   :laugh:
