Dear Chess Aadya,

My name is Gabor Balazs. I’m a Hungarian FIDE Master and a certified, full-time chess coach, so I hope I can help you. Everybody is different, so that's why there isn't only one given way to learn and improve.

First of all, you have to discover your biggest weaknesses in the game and start working on them. The most effective way for that is analyzing your own games. There is a built-in engine on chess.com which can show you if a move is good or bad but the only problem is that it can't explain to you the plans, ideas behind the moves, so you won't know why it is so good or bad.

In my opinion, chess has 4 main areas (openings, strategies, tactics/combinations and endgames) and if you want to improve efficiently, you should improve all of these skills almost at the same time. That's what my training program is based on. My students enjoy the lessons because they cover multiple aspects of chess in an engaging and dynamic way, keeping the learning process both stimulating and efficient. Of course, there are always ups and downs but this is completely normal in everyone's career.

If you would like to learn more about chess, you can take private lessons from me (you find the details on my profile) or you can visit my Patreon channel (www.patreon.com/Bgabor91), where you can learn about every kind of topics (openings, strategies, tactics, endgames, game analysis). There are more than 30 hours of educational videos uploaded already and I'm planning to upload at least 4 new videos per week, so you can get 4-6 hours of educational contents every month. I also upload daily puzzles in 4 levels every day which are available with a FREE subscription.

I hope this is helpful for you. Good luck with your games!

Learn exactly how to think in the opening, middlegame and endgame — this is what I teach.
Always blunder-check your moves.
Solve tactics in the right way.
Analyze your games.
Study games of strong players.
Learn how to be more psychologically resilient.
Work on your time management skills.
Get a coach if you can.

Basically every improvement guide on chess.

Watch Gotham Chess, he makes a new video everyday usually (he is on a break I think rn) and his content is insanely entertaining and instructive. I recommend his guess the elo series, its awesome.

i never new i needed this!

This probably isn't the helpful information you seek, but for me things just click after a while. I went from 800 to where I am now in just a few days after several weeks of struggling, though after that I got bored and pretty much stopped entirely until about a week ago.

Knowing how to play well is one thing. Being able to is another. Keep trying until things suddenly start working out for you.
