Brick wall at ~1050-1100 rating after 100 games

Just completed about my 100th game on the website and curious to get more experienced players opinions on my overall feel for the game at this rating (and being a noob with ~8 months of experience)

1) I often lose games due to one tactical error 15+ moves into the game, where my position completely falls apart in the next 2-5 moves, which feels awful. I don't think I have a good ability to see past 1-3 moves, and sometimes get completely dominated by some of the gambits / traps. Do I just need to have tons of moves stored in my memory for "if X happens, then do Y"?

2) Im not playing any of the quick modes, I think they are just unfun because i randomly blunder without having time to think. Are more / quicker games better to just 'brute force' learn rather than continue playing 15 | 10 games?

3) The accuracy system makes no sense, how much should i be paying attention to this? Is seems like I can play at 90% at this rating and still lose, or win with 65%.

4) My white record is 22-24, but my black record is 26-18, whats the next opening i should try instead of the London system? Im having pretty bad luck surviving past about turn 15

5) NO SHOT I'm 80th percentile of players at my rating of 1050.... I'm not interested in chasing a rating number, I'd just like to play games where either side doesn't make insane blunders and lose almost immediately after, however the games ive played with people 1150 plus have been so one sided it feels like im not even playing, they just run me over. Am I stuck in this elo range forever of just 'whoever doesn't blunder first wins?' If i cant compete with people even slightly higher rated than me?

1. You need to improve your pattern recognition. Tactical combinations are common in all level of play, you just need to learn how to recognize those opportunities and take advantage of them. You can practice your pattern recognition by solving chess puzzles, either on chess.com or lichess.org.

2. There are some benefits of short time control, as it allows you to build more experience with openings, and playing under pressure. But in general, especially when you are just starting out, it is best to build good habits and think through each move. So yes 15|10 is a good time control, personally i like 10|0 but it is all up to preference.

3. dont pay attention to the accuracy system, it is just a fun thing not a useful thing.

4. i reccomend playing a gambit, as it is easier to learn how to play aggressively and tactically at your level, it is much more difficult to pick up that skill at a higher level.

5. you are 80th percentile, majority are 600-800 rated. You are not stuck at this elo, you've barely played tbh. Start studying chess and you will break through. Studying chess invovles 3 major things. A) Playing/analysing games. B) Solvling chess puzzles C) Learning positional play (road to positional advantage by herman grooten is a good start).

100 games is nothing, many people go through 100 games in a week.

you can get up to around 1200 by just blundering less than your opponent. In that way it might actually be an idea to play queens gambit since the nuiance of london system gets lost at lower rating and you get more tactical positions quicker.

around 1100 rating i knew the first 5 moves of the opening, i learned more moves by making bad moves, studying theory gets pointless because you will be out of theory quickly at those rating. better to know how to take advantage of your opponents bad moves instead of just repeating theory.

Tactical errors are common, especially at the early stages of learning chess. Developing your tactical vision involves practicing regularly.

Don't focus too much on the percentage, but rather on understanding the reasons behind inaccuracies.

Improvement in chess is a gradual process, and consistency in practice is key.

I’m 168 games in and barely progressing in the 500’s. You are my role model.

I appreciate the advice / contribution of everyone. I'm trying to just get stronger at fundamentals and avoiding the dreaded 'mega blunder'. I have games where I don't seem make an insanely stupid move but still just get overpowered over time. I'm trying to learn from games that I've played by replaying positions to see if I can find a better move or fix a big error.

My opponents are finding these spots where I can't defend enough things and I have to give up something, usually as a consequence of a sequence of moves from 5+ turns ago, and I'm having a hard time seeing these positions develop before I find myself in a bad spot.

I guess my next question is how do I 'study' my games more effectively? Here's an example where we are close to even at move 21, but it starts going downhill from here, up until move 31 where its the beginning of the end. Apparently the engine thinks no blunders where played during this game. For all you higher rated players, was this just a miss? a tactical error? too offensive? did I just blindly follow a chess rule ( castle the king to safety ) at a really bad time?

any advice is appreciated, thanks again for your help

Play some quicker games, like the 3/2. It will sharpen your board sense and when you play a longer game it will feel like you are on vacation.
