Just memorizing moves without any understanding of why they are played is like being given the answers to a test. Yes you'll get 100% but you didn't learn anything.
Or as I also like to say. You can memorize the 10 best books on how to perform open heart surgery, but that doesn't mean you're qualified to perform the surgery.
But at the end of the day. Its choice. Whatever makes the game fun for someone.
For example:
• Some players can recite 15–20 moves of a Sicilian variation but struggle once “the book” ends.
• Others stick to simple systems like the London, but they actually understand the ideas better.
What do you think? Should we prioritize openings, or should we spend more time on strategy, tactics, and endgames?
