[Bug-gnubg] Question: Interpreting Evaluation Results |

Hi-
I would like to understand how to interpret evaluation results presented
with different plies and out-of-order equities.
In reviewing the results below, I would ideally want to conclude "at a
glance" that gnubg evaluates 24/21 13/9 as the best play, because it is at
the top of the list. It appears, however, that the moves are not sorted
primarily in equity value, but rather by ply-value and then by equity value.
So is gnubg saying that the best move is the first one, 24/21 13/9, or is
the best move the third one, 24/20 13/10, which has the best equity?
1 Cubeful 5-ply -0.199 24/21 13/9
2 Cubeful 4-ply -0.163 +0.036 13/10 13/9
3 Cubeful 2-ply -0.155 +0.044 24/20 13/10
4 Cubeful 2-ply -0.182 +0.017 24/21 24/20
5 Cubeful 2-ply -0.217 -0.018 13/9 8/5
. . . Many more moves, all with worse equity . . .
Thanks for any insight.
