Gotham Chess.

The best chess opening for beginners.

IMHO GM Daniel Naroditsky.

He doesnt usually publish much at a time, but all he publishes is top tier quality and very, very instructive. He has some good videos on trap openings and endgames, too, though they are incomplete.

IM Eric Rosen also has a great Speedrun going, basically like Naroditsky, and its a bit more accessible, too.

GM Hikaru Nakamura and GothamChess are fun, but often more entertainment. On the plus side they publish usually daily.

Other than that, theres of course plenty of stuf on YouTube if you look for specific questions.

Gotham chess is great And one more is for chess page 1

Gotham chess helped me

Gothamchess. I don't like any of his remotely recent content, but he is very good at condensing information into what you need to know while being entertaining. His old educational videos on various topics are very informative. If he was posting these when I was trying to improve, I certainly would have been a subscriber.

Agadmator: https://www.youtube.com/@agadmator. Watching his videos motivated me to get better at chess when I started. He uploads regularly, and he covers games played by high level players both recent and historical. He explains them in a way that a novice or beginner can mostly follow along. I think it is good for new players to see what actual chess games look like at the highest level. It will expand the scope of what you understand chess to actually be, give you insight into some higher level concepts and thought processes, as well as instill some inspiration and imagination in your own games.

NM robert ramirez and dr. Cans clinic

I agree completely that NM Robert Ramirez is perfect for beginners. His chess course playlist starts with the basics and builds from there. Highly recommended.

I also agree that Dr. Can's Clinic is a great channel. However, he mostly deals with more advanced concepts that are more suitable for intermediate players.
