I recommend to make a lichess account and do puzzles there if you aren't a member on chess.com. Review your games and look for your mistakes and try to correct them. Maybe read a book on openings to have a solid repertoire, I recommend "The Powerful Catalan" - by Victor Bologan. Or any other book that can help you get used to a certain opening.
Thanks, I will try to watch my matches although I might not know what to do.
I feel like I'm so bad, I only win by accident. I feel like I cant improve and only go down. Anyone can beat me if they just pay a little bit more attention than me. Please can anyone help me? Is there some way to improve? Anytime I try and practice I get beat, by the lowest of things.
