There was a 3-part BBC documentary called "My Brilliant Brain" with one that featured Susan, who was the oldest and is today one of the best live chess commentators in the world. The doc talks about her father's theory and practice. His most important understanding was that the child must choose the endeavor of their own free will, and then he merely helped them optimize their learning curve. Susan has a great quote about showing up to a men's chess club, when she was still young. She said, "I don't think I ever beat a healthy man." Because they were always not feeling well, or whatever lame excuse they conjured up. The other two parts of the series are on different topics, but are also interesting, but Susan's is our favorite, and I got them long before our son started chess. And Laszlo's book on chess problems is on my son's bookshelf. It has more than 5000 "problems, combinations, and games". It's been replaced by chess.com's and lichess's puzzle games, but it is still the reference book on chess puzzles, to my understanding.
