Position 1:

		White is Player 2 score: 0 pip: 2 Unlimited Game Jacoby Beaver pip: 9 score: 0 Blue is Player 1
XGID=-BA--A------------------b-:1:1:1:52:0:0:3:0:10
Blue to play 52

eXtreme Gammon Version: 2.19.208.pre-release

This one is obviously gin. There is no way Blue can win this.

XGID=-BA--A-----------------aa-:1:1:1:52:0:0:3:0:10
Blue to play 52

eXtreme Gammon Version: 2.19.208.pre-release

Blue still cannot win, but now White has to play it correctly 10 times in 36 shakes.

Blue has lost again, but what if White forgot to turn the cube? This actually happened several times is my matches.

Do you think White will cube at this score?

Blue claimed no gammon without moving his back checker. When I stopped to think about it, he got mad at me.
