In Response To: MCG vs. Stick Cube #1 (Matt Cohn-Geier)

Stick's game is a total mess, but he still has racing chances as he is only down 2 pips. I doubt I would seriously consider counting this OTB but since we are playing an online match it has the pip count displayed at all times.

I wasn't sure if this was a cube or not but I thought Stick would be taking. I also didn't think I was TG despite the stack of outside checkers.

As it turns out this is a cube but only by .01. Trying to time my window at this score is like trying to fit an elephant through a thimble. Stick thinks I should have cubed since it's not such an easy take. I'm still unsure...if I'm not convinced something is a cube I prefer to wait.

The score (after 0 games) is: GNU bg 8, user 0 (match to 11 points)

Move number 2: GNU bg on roll, cube decision?

GNU bg	95
user	93
