Puzzle: Create the Nackgammon starting position from a backgammon game

but maybe someone else can help!

I like this one ;)
How about:
Zorba : 0 Hardy : 0
1) 41: 13/9 6/5 22: 24/22 22/20* 20/18 18/16*
2) 22: 25/23 25/23 13/9* 21: 25/23 6/5
3) 21: 23/20* 21: 25/24 13/11
4) 64: 20/14* 6/2* 66:
5) 21: 9/6 11: 25/23 (2)
6) 21: 25/23 14/13
Just as a starter. I guess there are faster ways ....
