This is from a Nackgammon match.

GNU 2-ply says White wins 50.17% in this position. A take then since White is the favorite?

No, says GNU. It's a 1.04 pass.

I'm confused. I have always thought you should take when you are the favorite at this match score.

Can anyone explain what's going on here?

gnubg 4, petter 1 (match to 5 points, post-Crawford play)
