In Response To: Maybe I Missed the Cube Here (Bill Riles)

I got sick of not knowing whether this was a cube or not.

I definitely prefer to cube this one. The other one can go either way.

If you were playing against some random player, I would consider waiting more strongly, but I gather that Norm is not bad, so I think you lose more equity than you gain here by waiting.

The score (after 0 games) is: White 6, Blue 5 (match to 11 points)

Move number 5: Blue to play 42

White	105
Blue	131
