How can i get Higher Elo?


Yes. Always look at what your opponent is trying to do. Really look at it.
Don't just play the same moves you play in every game.
Look at your opponent's move.
Ask yourself if the move is attacking any of your pieces or your king?
Is every piece defended?
If you start doing that before you try to come up with your own move, your results have to improve.

I have been playing for 1 year. I never thought one day I would reach 2000+ when I was a noob. Keep practicing, and studying, you will get better soon!

I have a fairly new account but have played chess for years. After looking at your games, I've noticed you've left many of your pieces hanging, allowing your opponent to capture for free. I think for now, focus on simple development and protecting your pieces. That should raise your elo by a few hundred points alone. Then start working on other tactics and other skills. Keep building!

Analyse the games you've lost , by yourself or either through the engine and find a mistakes you made , think on the position for a while and try again with another move , then check the suggested move (engine suggestion or explorer )and try to understand the reason behind it and learn from it . Watching some videos or lessons might help

its good that you are playing rapid, keep that up.
I did notice you have started playing blitz, but longer time controls are where real improvement happens, so stick to those!

Wenn du möchtest können wir später eine Runde Rapid spielen. (ungewetet) Vielleicht kann ich dir ein paar Grundsätze erklären.

The biggest reason people struggle in lower-level chess is because of blunders. They make them in almost every game.
A mistake can instantly put you in a bad position, no matter how well you played earlier: if you had great opening knowledge, great positional skills, great endgame skills, whatever; a single mistake can change everything (you lose a piece or get checkmated).
So, how do you avoid blunders? Follow this simple algorithm:
While avoiding blunders is crucial, I also share a few basic principles with my students. These principles help them figure out what to do in each part of the game - the opening, the middlegame, and the endgame. Understanding these simple principles is like having a map for your moves. I provide my students with more advanced algorithms that incorporate these fundamental principles. When you use this knowledge along with being careful about blunders, you're not just getting better at defending. You're also learning a well-rounded approach to chess. Keep in mind, chess is not just about not making mistakes; it's about making smart and planned moves to outsmart your opponent.

Study the games of a certain Grandmaster, such as Magnus Carlsen, Kasparov, or even Bobby Fischer. See if you can spot any tactics within the game, it's fine if you don't see the point of every move, but even if you find one tactic in a whole game, it can help you recognise patterns and help you to improve in future.
