How to improve ELO rating?
Play in Elo rated tournaments.
Stop playing speed chess. All you're doing is reinforcing bad habits that will carry over into longer time controls.
Follow opening principles:
Develop towards the center.
Castle.
Connect your rooks.
Blunder check your moves by asking: "Are my pieces safe?"
After your opponent moves ask yourself:" What is my opponent trying to do?"
If you cannot do all of these things without losing on time then youre either playing to fast or playing to fast of a time control.
It's mostly about following key principles when playing. That helped me reach 2000+ and that is what I teach others to help them do the same.
Chessbrah’s habits speedrun, the Colle-Zukertort speedrun, and the queen’s gambit speedrun(new) which is nice if you are interested in learning the Colle-Zukertort or the queen’s gambit(it’s an opening/movie) then you should watch those speedrun series and the habits series too. I will let chessbrah explain the habits series. Explanation is the first part of ep. 1.
Remote Chess Academy: This YouTube channel is where you learn the middlegame stuff I talked about in #4 and the GM here explains it well and don’t forget this channel has a vid talking about the Colle-Zukertort too and endgames. This is the place where I recommend to search how to stop blunders.
Chess Vibes: Here is where you learn most of the small things that don’t matter as much as what Remote Chess Academy says, but all of the small things combined are more than what the YouTube channel Remote Chess Academy says combined and most endgame stuffs are here than other channels I have mentioned.
