In Response To: Cube action? (Michael Klein)

OTB I thought it was definately a double at this score and as White I would have quickly passed. I was surprised that my opponent, a fairly strong player, took. According to the rollout it is a clear double/pass and both not doubling and taking are huge mistakes ATS.

Match to 5, White leads 2-1
Blue on roll. Cube action?

Blue	123
