Gaspar danced again with 6-2, our roll...

I do think a cube is lurking..if not now, sometime soon. I therefore thought I would ask again.

I have no idea whether this is a double or not.  And every time I try to think about it I'm reminded of the GWC from the rollout two moves before - which don't tell me the answer, but are enough of a factor in my decision process that I'm just going to have to recuse myself from this cube decision.  So y'all are on your own for this one.

why did i vote no to the cube? is it because it could become too good, or is it because it could turn horrible. numerically are we ahead?, positionally maybe. would i take ? yes i would, and the game is too early, not to expect that cube to come flying back. i vote to wait

I agree with stog on no cube for the same reasons.  While I was thinking how to say it, stog said it for me and very well.   :yes:
