chess.com ratings aren't real. especially lower ones. we're not allowed to talk about why here. go play OTB to find out what your actual rating is.
it's a special place where elo 300-800 will play a blatantly losing noob opening, then later that game start ripping out a Carlson-perfect endgame 1 move / s when the magical number of seven pieces on the board is reached....
(also don't play blitz. also don't quit and close your account.)

I played over your most recent loss. It was a 10 minute game, and at the 52 second mark, you gave away your queen for free and lost. First, playing a slower time control is useless unless you use it. You saw a quick way to mate on h7, and never gave one second's thought to the knight on f6. Second (related to first), never make a move without considering whether it puts your own piece in danger. Look at all the pieces covering the square you want to move to. Third, take time to develop all your pieces before launching an attack. Get the knights out to f3 and c3 (or f6 and c6 if black), castle, get a couple of pawns in the center, and then start thinking about where to go next. Fourth, take some time to play over the great games of the masters--especially Morphy. Just watching their brilliant play over many games will give you countless tips and ideas. Finally, DO HUNDREDS OF TACTICS PROBLEMS. You have a free membership, so you're limited, but chesstempo.com allows unlimited tactics for free. Also lichess.org. And don't just look at them and stab out a move; study them and do some hard thinking and counting. Your chess will improve.

That's nonsense because you know whether you are cheating or not. You know whether you have reached your rating fairly or not.

I find the ANALYSIS BOARD very useful when I play daily. Slows things down and gives good practice in reading the board. I can try out many things before deciding on a move.

The easiest way to climb from 300 or 500 or whatever he is, is actually very simple.
You look at the analysis after the chess game. You see where you went wrong, and in the next game, you fix it.
You do this over and over again until you hit at least 1000. Then you can think about learning more complex strategies.
For example, learn the Ruy Lopez and Sicilian. Do that every game. Any area where you messed up, look at analysis.
Knowing the first 7 moves in the ruy lopez alone should get you to 1k elo.

That doesn't make any sense.

Knowing the first 7 moves in the ruy lopez alone should get you to 1k elo.
That doesn't make any sense.
Knowing the first 7 move variation in the ruy lopez should give you a very strong start to your games in 300-500 elo, and enough to get you to 1k elo.

First of all... after 1.e4 c5 it's worthless.
Secondly what do you even mean by the 7 move Ruy Lopez? There are dozens of variations. For example the one below is the Open Spanish, played by tons of GMs... in fact it was played in the recent Candidates Tournament (Nakamura - Caruana round 8)
---
But also, give any 500 rated player a solid position on move 10 and they're sure to blunder a piece before move 20... it doesn't matter what the opening was.
What matters is good calculation habits... and not to be too condescending because I know it takes a lot of practice but... knowing how the pieces move and doing your best to not lose anything for free is what gets you to 1000.
This (below) is why people get stuck at low ratings

It's a weird hill for you to want to die on.
But yes, I think learning the ruy lopez and its variations up to 7+ moves will get someone who is 300-500 elo to a higher elo like 1k.
I recently stated learning analysis was the most significant way to improve, which is 100% true. The blunder and all other issues you are talking about, can be solved by frequent analysis.
My point is that analysis and learning a common opening and its variations like Ruy Lopez will get you from 300-500 elo to 1k. You can debate it all you want, but I don't think you can really say it's untrue.
As you wish
