i am stuck at 250 elo any advice?

i started chess a couple of months ago and i got to 306 elo but then i went down really quickly and  then i could not go back up i have looked at youtube videos but nothing worked.

Blunder check before you move.

how do i show you one of my games? and also i do lots of puzzles every day my rating is 650 and what do you mean by blunder check? I can show you some of my games but I do not know how.

Tactics, Blunder-Check, Fried Liver.

Get a coach. No offense, but those who are stuck at such low levels generally have a very low capacity to absorb chess concepts, and that's why getting a coach will help you get through it.

Avoid blunders and u r 700 !!!!

Back in 2021 I started here. I had played the odd game through the years, but really only knew how the pieces moved. I had no real appreciation how truly terrible I was before deciding to give it a more proper go.

I wish I had decided to get into before 40 to have a better brain, but so be it.

At registering I picked beginner. Now I know I should have picked new to chess.

I went for a a month I think it was and rapidly plunged the ratings to 400. I was feeling rather defeated, so decided to stop for a bit.

Then st the start of this year for some reason I decided to start again.

The first week or so was savage as I dropped to late 200s and was just like what. I got really close to just deciding nope clearly I just can't do this.

In the end I settled on playing less, doing more puzzles, and thinking a bit more in the games. Just taking the time to make sure I was not doing anything really stupid.

I creeped into the 300s, but stalled a bit there briefly until something clicked getting a handle on not hanging pieces.

Don't get me wrong I am now only late 500s, so still hang pieces sometimes, but getting that under control so it is not "a thing" anymore made a big difference.

In itself it helps, but it has a knock-on effect of letting you pay more attention to other things once that is more habitual.

Then between puzzles and just taking the time to make sure I am not leaving a piece hanging, just look for checks/pins/skewers/forks for and against.

I found this made me rapidly shoot up. I am really no better at the game at 580 as I was 280. I have just reduced the number of blatant howlers that lose material.

I would also suggest trying to be reasonably consistent with your opening few moves. Find something easy enough to do and stick with it. I am just meaning the firstfew moves here. We are nowhere near learning openings properly as it were. Just to get an initital principled opening.

I am still awful, no doubt being a 500, but at least got some of the more extreme rough edges smoothed off a bit.

If I could get consistent I think that could get me a bit further. I can still swing wildly in form one game to the next.

The fool's mate/scholar's mate/early Queen parade starts going away in the 400s. Not disappeared totally, but eases way off.

Just think before you move, after the games look at what you clearly could do better and didn't see it during the game, read an openings book, try some lessons and solve puzzles.

Two pieces of advice:

1. Pay attention to the game. Don't just make random moves in 2-3 seconds.

2. Don't resign.

"what do you mean by blunder check?"
++ Think about your move.
Consider 3 candidate moves.
Calculate what can happen after each candidate move.
Evaluate the positions that occur at the end of the line calculated for each candidate move.
Decide which candidate move is best.
Do not play this intended move, but imagine it played on the board.
Now check it does not hang any piece or pawn, or run into checkmate.
Only then play it.

I've been actively studying for about 3 years and I'm still 450. My advice would be to have realistic expectations and have fun with the game, and with what you learn, despite your ELO.

After 3 years a rating of 450 is not normal. There is something very wrong here.

Take this game:

After7. Qxg7 white's queen is trapped. You can just catch it with Rh7. Even if you don't find that particular move, there are a million moves where you are at least equal.

Instead, you played a completely random move in 1 second (???), lost the rook and resigned.

That may have been a mis-click, I do that a lot - not sure though. 
I've accepted my rating, I was just giving my advice to the OP

It takes a while to get the hang of the game. At your level, just do this when you have the white pieces. 1. e4 ... expect your opponent to play 1. ... e5, if they don't, wing it. For now, just learn one idea. Now, think about "how can I capture that pawn on e5?", well, K-KB3 (oops, I mean Nf3) does that. And it gets your Knight off the starting square and into the game. Black now has to decide, do I prevent that capture or do I counter-attack (preventing looks like 2. ... e6 or 2. ... Nc6) counter attack looks like 2. Nf6 ...

And so forth. In chess, the opening is all about how to fight for control over the 4 squares in the middle of the board, combined with getting your pieces off their starting positions. If you can get through all of that ok, then you can think about the next steps.

So, as white, move your pawn in front of your king 2 squares. As Black, do the same as white (i.e. meet 1. e4 with 1. e5, and 1 d4 with 1 d5). Next, get a knight off their starting square. Next, generally look to get a Bishop off it's starting square, but look at what your opponent has done, and calculate what might happen. If all looks good, get your Bishop out. If you see something that results in badness, presume your opponent also sees that, and find a way to prevent the bad things.

That's chess, really. Your opponent wants to do bad things, you want to both prevent bad things, and if you can, do bad things.

Look at the board, think about how pieces move, and prevent bad things. If you can do that, you will win more than you lose.

what is elo?

Play bullet, and spam. Players under 1000 elo bullet will only know how to spam, spam and spam (like me, I guess...)
