List window: Openings - Opening Keys– Classification

 

This reclassifies the entire database into all keys (openings, themes, strategy, tactics, endgames).

 

 

If you interrupt the process ChessBase will remember how far the classification had proceeded, and you can continue the process again. The program will offer to continue where it left off (game number x). If you enter game number "1" it will reclassify the entire database.

 

If no key is installed, four buttons appear, please read on at: Install new key.
