After 35 days, the Ruy Lopez series is complete

Hi everyone, Stjepan here! After 35 days, the Ruy Lopez series is complete. Let me know what you think (Sicilian starts tomorrow!)

The Ruy Lopez series is complete. 35 videos total, covering every variation for black and for white. I tried to go into much more detail than in the original Spanish series from 2018. Let me know what you think!
I have created an Anti Ruy Lopez repertoire for black, and a Ruy Lopez repertoire for white. Both are available as annotated PGN files. The repertoire for black recommends the Closed Spanish and the Chigorin, and the repertoire for white is based on the exchange variation, but both cover all the sidelines as well.
All books on the Ruy Lopez, for both black and white are listed here. You can filter the books by opening, color, and first move, in case you need recommendations against other openings.
Here is the tool I use to study openings and prepare my repertoires.

Here are all the variations covered in the playlist:
