Once a pair of games is selected, a text describing the differences appears on the left, while the two boards show the first difference of the game.

A more complicated example is shown here.

If you click on the differences on the left, the boards will show the corresponding position.

If there are so many differences as in the last example, you can press the button 'Visualize differences' and you will get:

The colors are explained in the menu where also some additional examples can be found.

The button 'Blunder check' opens the following dialog. Here you get information on blunders, but only those positions are analysed, which do not appear in the other game.

This blunder check result belongs to another game played by Alekhine. Sometimes blunders are so heavy that you will identify immediately that the corresponding game-score is faulty.

If you switch from the games with differing results and moves (tab 'Differing games') to those without such differences (tab 'Identical games'), you will get information on other kind of differences.

If more than two files are compared, a game may have three or more different versions. That's why the presentation of the Game List is a bit different then.

The selected game has three different versions and you can select the pairwise comparisons within the Game List. On the left you see a description of the different versions with their sets of equal versions.

Comparison results are only slightly alterable: you may add information to the objects in the Game List (via the context menu). Compilations are similar to results, because the can be shown with the viewer, but you can add games from different results via Drag&Drop. Compilations are managed by the context menu shown here.
