In Response To: Standard 21/19 backgame (4/6) (Stick)

Went D/T OtB. I thought the double was marginal at best at the time. The gv in our shortened match seemed to push this into clear cubing territory. The take seemed dreadfully easy as a lot of numbers break the front of his mini prime and leave him in a poor state of affairs.

The score (after 0 games) is: gnubg 6, user 7 (match to 11 points)

Move number 5: gnubg on roll, cube decision?
