Each side played twice

From the standard opening position, each side (legally) moved twice. How is this possible?

SOLUTION

Congratulations to Bob Koca, Joe Russell, Brian Lonergan, Kevin McDonough and Casper, for solving the Seven-points Mystery!

Here is the sequence:

		White is Player 2 score: 0 pip: 160 Unlimited Game Jacoby Beaver pip: 167 score: 0 Blue is Player 1
XGID=-aa---E-C---dE---cae----B-:0:0:1:66:0:0:3:0:10
White played 61S, Blue to play 66

White wins the opening roll of 61, with which she comes down and splits, as shown above.

Blue rolls 66, and...

		White is Player 2 score: 0 pip: 163 Unlimited Game Jacoby Beaver pip: 143 score: 0 Blue is Player 1
XGID=bAA---EAB---dC---cae----B-:0:0:-1:11:0:0:3:0:10
White to play 11

With his 66 roll, Blue played 13/7 13/1* 8/2*. Is that not the way you would have played it?

Here, White rolls 11, and...

		White is Player 2 score: 0 pip: 159 Unlimited Game Jacoby Beaver pip: 190 score: 0 Blue is Player 1
XGID=-aa---EAB---dC---bbe----BB:0:0:1:00:0:0:3:0:10
Blue to play 33

White played bar/24* bar/23* 8/7.

Now, Blue rolls 33, and plays bar/22(2) 13/7, thereby reaching the target/final position below.
