Part 1 is here.

Part 2 asks for cube action in this position:

		White is Player 2 score: 1 pip: 70 9 point match pip: 123 score: 2 Blue is Player 1
XGID=-BCBBD--A---a-bbbbbbAb----:1:-1:-1:00:1:2:0:9:10
Blue on roll, cube action?

eXtreme Gammon Version: 2.10

Let me share XG Roller+ for starters:
