Ten-roll BG Puzzle

Recently, Tom Keith and I discussed a hypergammon position that can be legally reached in 11 rolls if White played first, or better yet in 10 rolls if Blue played first. [For reference, the position is: Blue has two checkers on his 8pt, White has two on her 1pt, and each side has one off.]

That got me thinking about positions that can be legally reached in regular backgammon in about 10 rolls.

		White is Player 2 score: 0 pip: 227 Unlimited Game Jacoby Beaver pip: 167 score: 0 Blue is Player 1

Position after 10 rolls

Starting from the opening position of backgammon, how can the above position be reached after 10 rolls (5 for each side)?

(You are not told who played first.)
