I've been playing for a bit and following all the opening principles, reading the guides, doing lessons and puzzles, and even analyzing my games when I get a chance to use a free analysis. Even still I couldn't break 500. It really doesn't help when so much of the community then turns around and says "well if you're under 1000 you're clearly blundering all the time." Like that doesn't help me at all.
I also have pretty even and well done games with people of higher scores and also tend to get knocked down by people of lower score as well. It's like I literally can't progress. And when I ask for help all I get is the same responses with a link to some blog or the opening principles or the "Analyze every game and see where you missed."
For One thing, I can't afford the analysis after every game. I don't have the money to pay for premium and I'm playing to enjoy myself and not be reminded of my financial situation. Second off It'd be nice to actually have somebody to at least guide me or try to give me some advice for where i'm falling and not just be brushed off as a "blunderfest" just because my rank is so low. And when you do get advice it always boils down to "stop Blundering" and "think 2 moves ahead of your opponent".
Like how? If I knew how to stop blundering, I wouldn't be asking you how to stop blundering. And I wish I had the psychic power to know what my opponent is going to do 2 moves ahead. I guess that's just something Chess players can do that I haven't picked up yet or something.
And the worst response is "Keep playing, you'll learn from playing." That's what I've been trying to do but the more I play, the more I lose. I find I'll go on, have a good couple games, then start dropping in quality and getting my butt kicked shortly after out of nowhere. The only thing I've learned from this is that people like to taunt you into resigning when you start losing, and nobody is actually willing to help you unless you pay them or subscribe to their youtube channel.
There are many things beginners can do to improve. When you ask for help in this manner, you get help. Pay special attention to the comments by @pfren. He is a titled player and quite generously took a look at your games and made some perceptive observations.
It is quite possible that you are not implementing opening principles as well as you think. I looked at your most recent game over 30 moves and saw that you inflicted a lot of weaknesses on yourself. Your opponent took advantage. It is an opening principle to reduce your vulnerabilities, not create new ones. Specifically, when your opponent puts a bishop on g2, you want to be careful what you do on that diagonal. In order to protect a bishop, you exposed your rook.
As for blunders, these do decide almost all of your games. Some blunders are hanging pieces. Some are weakening a diagonal where you have a rook and your opponent has a bishop.
My games, too, are decided by blunders.
A coach would do you some good, but if you cannot afford a premium membership that’s not going to happen. Do what lessons that you can. I think you get a couple per day with a free membership. Find a video series that you like aimed at beginners. There are lots of them on YouTube. I prefer books myself, and if that is your approach to learning, I can make some recommendations. One of my top recommendations is available free online: https://chesstempo.com/chess-books/chess-fundamentals/book/165 and also at https://www.chessable.com/chess-fundamentals-by-jose-raul-capablanca/course/66428/
ChessTempo presents his book as he wrote, but silently correcting one error, as did Batsford when they issued the book in algebraic notation. Chessable seems to have altered it a bit.
I was about to respond to this saying "I reverted my initial opinion on this post pages ago", but I have to say I heavily appreciate this too. as @nMsALpg said, I myself am recognizing some of these faults even in my more refined gameplay now as well. And have found that the principles have definitely helped me as well in mid and endgames. You guys are dope and I appreciate you.
Haha, yeah, sometimes I'm playing against a French or Sicilian, and thinking to myself (jokingly) "look at this garbage player, I'm so far ahead in development I should just sac a piece"
Typically we're in some main line though, so I don't do that
