Blue is Player 1
XGID=cBBBB-B--AAAbA---ccbbA----:1:-1:1:00:0:0:3:0:10
Blue on roll,

Part A: Find a roll sequence starting with the position above that meets the following conditions:

1) Perfect checker play and cube action on both sides, according to XGR++ evaluation.
2) Neither player ever rolls 55.
3) Blue goes first (he is on roll).
4) White recubes at some point.
5) White closes Black out.
6) White bears her last checker off when Blue still has five checkers on the bar.

Part B: What is the shortest sequence you can find that satisfies all of the above conditions? (Fewest number of White rolls.)
