lesson recommendations for easy theory

Been a Chess.com member off and on for a while. I feel like they've improved the puzzles a lot, or at least I appreciate them more now.

That said, maybe I'm too old but I kind of miss Chess Mentor, how you could kind of look up lessons in a specific area at a specific level of difficulty, and have great explanations from Jeremy Silman (RIP). A lot of the newer ones are kind of bland AI generated things, or you have one from a human but it goes incredibly deep into only one topic.

I'm kind of wondering what the best way is to find "broad" lessons here at the intermediate level. Like broad openings, broad endings, etc.

Check out the courses if you are a premium member, there are a lot of great things, especially around openings.
