8.4.2 Analysis panel

You can also study your moves and cube decisions in more detail in the analysis window, or analysis panel if you have checked Dock panels in the Window menu. You can open this window by checking on Window->Analysis. If you have docked panels the analysis panel will appear under the game record. The analysis window is basically the same as the Hint window described in the "[[Playing a game or match]]" chapter.

The Analyze pane

In the figure you can see the analysis panel. At the top of the analysis panel you will see three pull-down menus. The leftmost pull-down menu is a comment on the cube decision. In the figure it is a position where the player didn't double and the GNU Backgammon's analysis of this is empty. There was nothing wrong with not doubling in this position. The user can also override GNU Backgammon's evaluation and mark the cube decision as 'Doubtful', 'Bad' or 'Very bad'. Note that the cube decision pull-down menu will only be visible when the player has the cube available.

The next pull-down menu shows a simple analysis of the roll. The roll in this position was 32. GNU Backgammon's evaluation of this dice roll is also empty. It shows that this particular roll was -.162 equity worse than the average roll. This means that the roll is a bit unlucky, but does not qualify for being marked as an unlucky roll. The rolls are marked in these categories: 'Very lucky', 'Lucky', 'Unlucky' and 'Very unlucky'.

The rightmost pull-down menu, shows the move which was done. In this situation the move that was done was 3/off 2/off. This move did not qualify for any mark. Moves that GNU Backgammon don't like will be marked as 'Doubtful', 'Bad' or 'Very bad'. The user can also override GNU Backgammon's evaluation and mark the move manually with the pull-down menu.

The rest of the analysis window is a notebook of two pages. The first page is the list of possible moves. The list is sorted in the ranked order with the best considered move at the top. The moves are sorted by equity or EMG. In the list in the figure there is only two possible moves. The move that was actually done in the match, is marked with red color. The only difference of this list of moves and the list of moves in the hint window, is that this list does not show the probabilities for each outcome of the game. If you want to see the probabilities of the different outcomes, you can click on the button labeled Details. This will then show you a list with these numbers.

The other page of the notebook is the cube decision analysis. This analysis show exactly the same as in the Hint window described in the chapter called "[[Playing a game or match]]". Note that the cube decision page will only be available if there is a cube decision. It will not be visible if the cube is not available to the player.

There is also a set of tool buttons in the analysis panel. These buttons does exactly the same as the tool buttons in the Hint window, which is described in the the chapter called "[[Playing a game or match]]".
