In Response To: Cube action? (Joe Russell)

I really enjoyed reading that. I found it both interesting and informative.

The initial 2ply said D/T, the rollout overturned it quite impressively into a pass. Extremely surprising how big the swing is on the rollout. I was personally disappointed to be passing it at the time, and wondered how bad it was. The big problem I felt I was facing was that it doesnt matter how tricky it is for my opponent to play it, I have an equally tough job myself.

Rollout here, 2/2 below it.

The score (after 3 games) is: superlady 1, kilted 3 (match to 5 points)

Move number 24: superlady on roll, cube decision?
