Stuck at 400 ELO and I've been playing for a year.

Hey buddy I can relate. I’m stuck at 200-300 and I’ve been playing for 3 years.

Lol you cant really count your playing time in years. You played a couple hundred games in a year and I played like 6000. Thats why you shouldnt compare yourself to others by how long theyve played.

I AM ALSO SINCE 3 YEARS IN BLITZ AT 400, ESPECIALLY WITH THE MANY LEAGUE GAMES IT WENT DOWN. I AM NOT ABLE TO THINK SO FAST, THAT'S WHY I PLAY DAILY GAMES A LOT ALSO.

Right, if he is beginning chess, 100 games are nothing, especially if he plays blitz

I m stuck at 300 for 3 years too.

you need to get more luck its that easy

And even if you played same amount of games over same amount of time, the quality of learning can differ between play-n-forget and play-n-review.

Also, it kinda works* measure in years if we have a standard unit: one year of playing chess at the club is one - two evening for hour and a half each week, for ~45 weeks (because vacation and holidays). But there is no standard unit for online chess.

* not really since one person can just come to the club, play some games, do some puzzles and chat while the other also spends their time outside the club to study and participate in tournaments.

You have a valid point there.

I have about 350 rapid games in little over a year and the last 3 months I rushed in about 130 games only to see my friends are at 3000+.

People progress differently.

people say under 600 dont know the rules because theres been plenty of people who start chess and literally start at 800 and achieve 1000 pretty fast where then they actually start studying

everyone is different

puzzle rush doesnt give you an edge but its stll good

puzzles helped train ability to spot tactics and stuff i guess

but yeah its not that much related but its still a 2000+ rated player

if a player trained from 20 puzzle rush to 80 he could probably have his rating at least go up  a bit at lower rating levels

Having knowledge = the information is somewhere in the brain, but when you play a game, it doesn't come out. 

Putting knowledge in your game = information is there immideatly. 

The trick is to improve the prioritzation of your pattern recognize ability. Look at board, you see millions of patterns, but which are important and which aren't. You don't know, because you aren't trained.

How do you train yourself? 

Apply the following to every game, in the following order:

• Evaluate board position

You first need to be able to evaluate the board like an AI, what is the difference in points? Who is ahead? Every time you play chess you see a board, you must be able count the value of both sides, without looking at dangers etc. What is the count? This is important, if you don't know the value of the current position in detail, how can you know the value of the future position? Look at stockfish evaluation for value: https://www.quora.com/What-is-the-algorithm-of-Stockfish-13 

You might think: value is not important, I only need to know how I can decrease opponents pieces, after that I am automatically ahead. If you think that, you are wrong, because you need to know how much damage you exactly do with every move. How else can you weight two future positions against eachother, if you don't know what the damage is? Also you need to know where the value is residing. Some potisitions are very valuable and bad defended. What if you start hunting a pawn, but opponent attacks your queen. 

1. Look at the big dangers. What can the opponent do to decrease the value? Hanging pieces?
2. Look at your opponent current or close tactics, pins, skewers, forks etc.
3. Look at what can he do to improve his own value  (by pawn promoting or giving himself a better board position)
4. Look at the dangers you can do to the opponent.  Hanging pieces?
5. Look at the tactics on your side
6. Look at what can you do to improve your value 
7. Look at the tactics the opponent can create but are relative far away, can his horse fork my queen and king after 4 moves?
8. Look at the tactics you can craft but are relative far away

denial.

the first step to getting better is to admit you’re not good (or at least, as good as you would like to be)

I mean, this is one of you recent games where you don't blunder or hang pieces like queen:

Number one lesson for everybody in getting better at anything and everything: be honest about your own abilities and flaws so you can learn from them.

I checked your games and every single one is decided by a hung piece or other material. Getting rid of simple mistakes is the way to get to a 1000+ rating.

i was trolling here

This is not true . I m playing chess for 5 years here and on li chess. And I m 450 rated . On my previous account I was 350 rated, after playing 1000 games. So, it's not simple that getting rid of simple mistakes make anyone 1000+. It's superficial advice for someone who is low rated. Like 'if u know how the pieces move ' u should be atleast 1500 rated. All these things are senseless. 

Okay. Link here a game that you lost, that wasn't decided by a simple mistake. You get to prove me wrong.

Two games  by same person and so much difference in level of play.
