In Response To: ME Cube action (David Rockwell)

After scolding myself for seriously considering taking a crap position like this again, I noticed that white actually had a lot of bad numbers (as enumerated by Stick). So, I took. Passing is as big a blunder as the redouble was.

The score (after 0 games) is: gnubg 6, user 2 (match to 9 points)

Move number 5: gnubg on roll, cube decision?

gnubg	66
user	49
Position ID: v+8AACC2bxsAAA Match ID: AQEgAWAAEAAA

• gnubg doubles

Alert: wrong double ( -0.1653)! [very bad]
