You can configure how GNU Backgammon analysis the match or game for you. This can be configured in the dialog box that appears when choose Settings->Analysis.
Analyze settings dialog
[[analysesettings.png]]
In the top left frame in this dialog box, you can select what to analyze. GNU Backgammon is able to analyze three different properties in a match.
In addition you can have the analysis to analyze just one of the players, or both. There is also possible to set a limit of how many moves to be analyzed at each position. When you're reviewing your match, the number of analyzed moves will be limited to number in this field. However, if you want to analyze further moves in a particular position, it's not a problem to do that later. The move that was actually done in the match will be analyzed even if it is ranked below the number of moves limit.
GNU Backgammon will also mark each move or cube decision with Doubtful, Bad and Very bad. You can adjust the limits in equity difference for which label to assign. This is done in the frame box to the left. Notice, currently the Good and Very good classes are not used.
You can also adjust the classes for what GNU Backgammon considers lucky and unlucky rolls. The luck of a roll is defined as the difference of equity after the best move after rolled dice and the equity after best move averaged over all possible rolls.
The right part of the dialog box is an evaluation setting for how each move or cube decision should be evaluated in the analysis. For an explanation of this settings, see the chapter called "[[Evaluation settings]]".
