item. The Insert button will be only enabled if you can insert the copied item. A dropdown will let you select Add Repertoire Item.
Special Case: Add moves
Sometimes you want to copy just parts of your opening into another one. For this purpose you can use the copy function as well. However, it works slightly different. Show the opening of which you want to copy the moves. Then navigate to exactly the position from which on you want to copy all moves. Click on the Copy button. Now, depending on which repertoire item you select as the target you can either insert the complete opening or just the move. If you click on another opening you see the command Add Moves enabled. That means you can add the moves of the source opening to the target opening.
If you add moves from one opening to another the following happens: First, all moves of the move list of the source opening are copied to the target opening. Then, starting from the last position of the move list of the source opening all derivable moves and positions are copied too. This will be done recursively. In other words: Any position which is reachable by any move order( which is represented in your source opening) from the current position on will be copied.
Let’ s have a look at the following example:
The position explorer shows all moves of the current move list with a white font. The current move list ends with“ d3”. Now, if you copy and insert these moves into another opening the program will add all moves from“ 1. e4” up to“ 3. d3”, but also all moves after“ 3. d3”. You can see that there exists an alternative to“ 3... Nc6”, because there is an icon indicating you can expand it. The same is true for“ 7.... Bxf3”. All these alternatives are
