I found my best improvement to come from puzzles. They help with your intuition and decision making, both reducing the amount of tactics you miss and the time you spend on your moves. I was stuck around 900 for a long time, but when I started doing puzzles (alot of them), i got myself to 1100. Once I started doing puzzles the right way (actually taking my time and calculating them out, as opposed to quickly trying to solve it), I was able to increase my rating by another 300 (In a bit of a slump right now).
Besides this, you should just play games. No matter how much practice you do, nothing beats getting beat so bad that you learn from it. I have not spent that much time learning openings. Instead, I chose a couple to start the game with, and learned what to do and what not to do from trial an error.
How can i improve myself in chess?
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.

Good luck either way!

Puzzles can be helpful. The most important thing to aid improvement is to play slow games, 10 minutes or slower; and actually use the time to look at the position before you make a move.
Get into the habit of being absolutely sure you're not putting your piece where it can just be captured! Double check and be sure you're not blundering! It happens, we all suffer from board blindness at times, but work to reduce it.
And, similarly, before you move remind yourself that some squares you now control you are giving up. Sure, you could move that Knight, but if it is the only thing protecting your Bishop from being taken by their Rook, then it might be better to consider a different move. But, if your Knight Checks their King, maybe it is a good move after all ... in other words, think the move and its consequences through. Once you move, it is your opponents turn, so what will they do (or perhaps, what is the best move they could make) in the new position you are thinking of creating and decide if you can live with that.
Also, be very cautious about making a move that lines up a valuable piece, like your Queen, with your King. If they would end up on the same rank or file, can your opponent put their rook on a square that they control and end up winning your Queen? If they would end up on a common diagonal, it's the Bishops that you worry about. (And also, if your opponent lines up a rook or queen with their King, look to see if you can do the above). Even if they can't do it right away, there is always that risk and they may start making moves to try and make that threat a reality!
Check all your pieces and ask "Is that piece defended?" Check your opponents pieces and ask the same thing. Undefended pieces can become targets, you don't want to have targets, but you want to spot your opponents. If you have an undefended piece, you might want to consider moving it to a defended square, or getting some defence in place. If you see one, then start to attack it, and if it then gains defence, bring in another attacker. If you have more attackers than they have defenders, then it may be the time for taking it has come. Of course, if your attackers are 2 rooks and a knight, and the piece is a Bishop defended by two pawns, probably not. Counting attackers and defenders is important before you start a series of exchanges.
If you are ahead in material, trades are good for you, but if you are behind, they are not. Do not trade just because it is an option.
Don't move a piece to a square if the opponent can just force it away by moving a pawn, unless you want them to move that pawn for some other reason or you are planning on making a 2nd move of that piece anyway and the pawn move doesn't destroy the plan.
Do not forget that just because you are in check doesn't mean you have to move your King. Can you capture the checking piece? Can you block the check? If you can do either or both of those, which option looks to be the best one? Block, Capture, or Move. And don't rely on the opponent moving their King just because you check them: Consider what replies they might select from (Block, Capture, Move?)
Those are the sorts of questions you want to be asking on every move. As you improve, you will add more to your decision making by adding in aspects of how to improve your pieces, such as looking for outposts for your knights or how to get your rook to an open file. But as a beginner, the first step is to deal with board blindness, those overlooked blunders "Oh, I didn't see that your Bishop could capture me" type thing. As the above becomes a habit, it won't take as long, and you will improve.
Hi im a beginner and i wanna imrpove myself. So how can i do this? Should I solve the puzzle im trying to ask or what should I do?
