This database contains all relevant openings that players should know for ratings below 2200. If people find errors or not mentioned moves in it please report. Together we can maybe build an even better base.
All endpositions are analysed with stockfish 16 and depth of at least 25 moves. So it took a few weeks to complete

I think it is a very good start for people who want to build there own repertoire.
I have also attached my Ecomast.4MD which is constantly updated by me.
Please let me know if somebody is interrested in this project.
