tion where you would like to create a variation. Now you can create the variation. It will be automatically added
to the current opening. The variation will be defined by the current move list. You can’t change it later.
Variations don’t contain any unique moves or positions and depend on their parent opening. If you delete the
corresponding opening the variation is deleted too. On the other hand, if you delete the variation it has no impact on the parent opening. A variation has no training score either, because it doesn’t own any positions.
You can add as many sub-variations to a variation as you like. You can move a variation under another variation as long as they share the same parent opening. In this case the variation will change into a sub-variation.
If you show a variation the parent opening is shown and the move list is update with the move list of the variation. Thus, variations provide you a way to easily access key positions. Some openings are rather complex and
have some sub-systems. Variations and sub-variations will help you to make them still easy to maintain.
4.3.1.1.5 Sub-Variation
A sub-variation works like a variation except that they are added to a variation and they can’t host any further
repertoire element. They are always a leaf node in the tree. However, you can move them directly under the parent opening and change it this way into a variation. A sub-variation can’t be moved to another opening than the
parent opening, similar to a variation.

4.3.1.2 Import
You can add new moves to your opening manually or by using one of the different import functions. One thing
which they all have in common: only new positions and moves are imported. If your source has positions which
already exist in your database they will be skipped, so never worry about this.
