Zorba rolled a 4-2 and entered one checker.  Our next roll is 5-1.

It's hard to argue against covering the blot.  Then it seems like playing the one as 8/7 is obvious.  Slotting the five seems unnecessarily risky.

I don't want him to anchor, but hitting loose and leaving a second blot seems over enthusiastic.

8/7 6/1

Ok, the vote's 5-0, and seems like a next, so I'm going to call it early.

I didn't bother to roll this one out.  2-ply analysis has our play best with everything else being a double whopper.
