I was looking at a move I made which gnubg flagged as bad, and I can't
see why it's flagged that way:
Position: ZbsBAB7nbjMAAA
Match Id: cAlmAQAAAAAA
GNU Backgammon Position ID: ZbsBAB7nbjMAAA
Match ID : cAlmAQAAAAAA

>From the Annotation window:
1. Cubeful 2-ply 5/4 5/1 Eq.: +1.033
0.728 0.371 0.009 - 0.272 0.027 0.000
2-ply cubeful 100% speed, 8 cand., 0.16 tol. [world class]
* 2. Cubeful 2-ply 8/7 8/4 Eq.: +0.950 ( -0.083)
0.730 0.413 0.016 - 0.270 0.027 0.000
2-ply cubeful 100% speed, 8 cand., 0.16 tol. [world class]
The move I made 8/7 8/4 has a
higher probability of a win 0.730 vs 0.728
higher probability of a gammon 0.413 vs 0.371
higher probability of a backgammon 0.016 vs 0.009
and the
same probabilities of being gammoned or backgammoned. So why is the
equity lower? What am I missing or misunderstanding?
