How to study chess?


When we study chess we are not trying to memorize the moves, rather we are trying to learn, comprehend, and apply the concepts we learn, similar to many other aspects in our lives. for example, in math you dont remember every single way to multiple every number, you learn how to do multiplication and then you apply the method in which you multiply.
A basic concept that you should be learning around your rating is pawn breaks. Which is the idea to open up your own position via changing the pawn structure. Nearly every position has pawn breaks good or bad, which is why high level players will always have them in their mind, and evaluate if they are good or bad.
So once you learn this lesson, now as chess players we must apply what we learn by trying to identify potential pawn breaks and evaluate whether it is good or bad. Hope this helps and let me know if you have questions.
Edit: Admittedly I went a bit deep into analyzing the game

First, the best option for study chess is to learn the chess languange, we usually don't say "king's pawn moves 2 squares", we just say e4, it is easier and faster, it would take me a while to explain, so I suggest you to take a look on this video:
Btw, we can call it "chess notation" too
After you r done and be able to regonize the languages for each moves, you need to learn oppenings, gambits and defenses.
Hope this helps you.

Focus on understanding. Not on memorizing.

Improving at chess is usually not easy. If you can afford few lessons, I would advise getting a coach. I can teach you how to think during the chess game. After that, your progress is inevitable.
If you can't afford any lessons, here is the excerpt from very good article on how to improve:
Play a lot, analyze your games, and primarily study tactics. Your knowledge of openings, endgame, middlegame, etc. will come from analyzing your games and going over grandmaster games. Only study one of those specific topics if it is clear you are specifically losing because of that topic.
