This is what I call a "straggler vs anchor position." Back in February, when I introduced this terminology on rec.games.backgammon, Stick said, "the other types of games you mention, single straggler v. single straggler or single straggler v. high anchor, aren't all that interesting in general. Run the guy, end of story. Yes, window for you to show the exceptions...but really, run the guy." However, in this position, the computer doesn't like Pottling. 8/2 is close, winning the most games pseudocubelessly according to this rollout, but as Mochy has said, "I hate 8/2. It is illegal in Denmark."
