		White is Player 2 score: 0 pip: 181 Unlimited Game Jacoby Beaver pip: 156 score: 0 Blue is Player 1
XGID=-c---BE-B---eD---b-cb---B-:0:0:-1:00:0:0:3:0:10

Using XGR++ evaluation as arbiter, the minimum number of rolls I found to reach this position with perfect play is eight (four for each player). If 64R is permitted as an opening play, it can be done in six.
