In Response To: Cube action? (DC-Ohio)

Someone with Snowie mind rolling this out, see how it turns out?

OTB White doubled, blue passed. I think the double is obvious, +63 pip count doesn't come around every day you know...

If you take and lose, you have 0% MWC. If you take and win you have 100% MWC, if you drop you are at -2/-1 in crawford play, so you have to win two in a row. Personally, at -2/-2, I double whenever I'm even slightly ahead, so my cube would have never been centered so long. With such a strong board, and so many rolls leaving shots for white, I think I take this cube all day long.

Cube analysis Rollout cubeless MWC 60.28% (Money: +0.472)

Cubeful equities:

1. Double, take 66.97%

2. Double, pass 68.75% ( 1.78%)

3. No double 60.68% ( -6.28%)

Proper cube action: Double, take
