First, it's about practice. The more you practice, the more you can remember and play moves. I can't recall the name but I read about some platform that allows playing quizzes and other practical tools to practice moves that you learn and thus, remember in the long term.
How can i undertsand from books


1. Assuming that you feel the lesson from the book you’re struggling with is unique and valuable, re-read the book one more time. Kasparov’s last series of books tend to do this to anyone less than GM level.
2. Pick up a different title with the same/similar lesson/motiff and see if you remember the presentation by a different author/teacher/instructor. Thank capitalism for this option.
