Dont play blitz! Give your brain a chance!
Help! My rating is 650 in live chess (blitz)

Only God knows how it is possible to end up with a rating of 600.
I would seriously consider another hobby, if you have tried chess for a few months and only got this far.
My first and most important advice is don't listen to this guy. He is being stupid.
Chess is a game. It's meant for enjoyment. So what if a person spends a few months at 600 rating, people spend their whole life times in 600 rating or worse they spend their whole life times never even attempting chess or giving up on chess. And then you have people like this dbag who discourages people from playing the game. Its a game! So what if you quote "have very little natural aptitude for it" or "are unlikely to reach satisfying milestones". It doesn't matter, just play and have fun.
Me personally I spent years at 600 playing on again and off again. I can tell you I had a lot of fun even when I was at 600, It was a great way to bond with my dad. Eventually made it to a peak rating of 1830 in 2016. So I can tell you right now that it can be done and its not because of so called mental aptitude. Don't listen to people like Peppinu.
If you want to improve, I put together a detailed guide on kind of what to expect at each elo level check it out.
From a 500 ELO Beginner to a 2000 ELO Expert

It depends what the beginner did.
If they just played randomly for a few games, a few times a week, then probably after 1 month their rating will be zero
But if the beginner was learning about basic checkmates, and tactics, and opening principles, and playing seriously for multiple months, then it's a little different.
I was researching on this topic today and came across this thread. I realize the OP is not likely to see this as he's either moved on from chess, or at the very least this particular account.
However, I've not seen a single response that adequately explained to him what was going on so at least for the benefit of other people who may come across this thread, I'm going to give this answer....and much of it revolves around the interesting workings of the ELO system and in particular, Glicko RD.
My interest in this topic began with my little brother. I began voraciously studying and playing chess in 2017 and he began roughly six months after me. However, even though we started around the same time, I put in much more work to learn and in our first ten matches I was winning all of them. In time his blitz rating seemed to stabilize at around 1150. I was at the time pushing 1300. Then one day he made a burner account, because he needed to use a different phone for work. To my shock, he shot up to 1408 even though he had never been past 1200 on his main account. I found this odd, but in time came to understand.
I looked into this and immediately noted three things; he only played about a dozen games, the the people he matched with all seemed to have new accounts as well, and he was gaining an insane amount of points for each win.
So in comes Glicko RD. RD stands for rating deviation and "Glicko" is named after Ron Glickman, the man who devised the system. Glicko RD is essentially a confidence interval in which the system thinks your "true" rating lies. The higher the number, the less accurate your rating may be. Obviously new accounts start with the highest possible value. Glicko RD will decline as you play more games and the system becomes more confident what your "real" rating is. Frequency of games also comes into play. If you play many games very often Glicko RD will decrease and if you leave your account dormant for some time, it will gradually increase. This makes sense, right? After all if you leave your account for two years it can be said that during that time either your skills declined or maybe you got much better on a different platform. During that time of absence the system in time becomes less confident it knows what your real rating is. Another thing it factors in is how stable your rating is. If you go on a year and suddenly increase or decrease in rating over a short period of time, the system once again is losing confidence it knows what your real rating is.
Now this system aims to do a number of things, one of which, is to get you to your "true" rating as quickly as possible. This is why points are given and taken at a much greater rate with a new account. Say, for example, a 2000 level player creates a brand a new account and starts at 1200. Well, if he only received 10 points per match, he's going to have to beat down other players some 80 times before he gets to people on his level. This is not very constructive for anyone involved and on a system wide basis is going to create a poor experience for users.
Because of this system, though, it's very common for new accounts to shoot to a high rating early on but as enough games are played, the "real" rating eventually emerges.
Further exacerbating this condition is the intelligent matchmaking. The system isn't merely going to search out another 1200 rated player if you are 1200. It will search people that not only have a similar rating, but also similar Glicko RD and number of games played. This means that for people who early on shot to 1300-1400, they did so by generally playing against other people who themselves were not "real" 1300-1400 players.
I think it goes without saying that two accounts can be 1200, but are very different if one is a brand new account while the other one is the result of a person steadily climbing there over months. The system knows the difference, and has a tendency to not match people like that. This is obviously a problem for people who like carpetbagging. If you have reached 1300 but have intentionally dropped to 600, the system will seek out people like you and you could actually face a similar level of competition that you had at your real level. This basically protects the lower rated players and in general insures that you are being matched with an opponent of similar skill.....even if you are actively trying to avoid that.
So for anyone wondering what their "real" rating is, just ask yourself two questions; can it be sustained and can it be repeated. If not, then the chances are good that your "max" rating is no representation of any skill you ever had, but more likely just a by-product of the ELO system figuring out what your real rating is. For example, my maximum is around 1400-1500, however, I slowly climbed to that point, and I've also sustained and repeated that across different platforms and formats.
In general I find the ELO system to be both brilliant and elegant from a mathematical perspective. I find it very awesome that there is this system of equations that when implemented, is able to very intelligently pick opponents for you and also help you gauge your general skill level.
However, it's no perfect system, and there is a very real thing that the video gaming community lovingly refers to as "ELO hell." This means a variety of things, but for me, it is when I drop in rating and find that the lower rated guys I'm facing are now just as hard as before, only now I lose more points to them and gain less points for winning.
At first this is really discouraging as you start to wonder if you've maybe lost your touch . In my most recent foray into the ELO underworld, I had dropped to the 1200's and would find myself against an 1150. Well, I don't play the same against these guys. I try more traps, tricks, and aggressive attacks and focus less on prophylaxis and long term planning. Then you find inexplicably that this low level guy knows everything you are doing and schools you. If you find yourself here, take a look at their account. In the last week, I looked at five back to back games against 1150-1200 guys and each one of them had a max rating of 1500-1600. My max rating is 1456. This means, chances are good, these guys were actually better than me even though their rating was lower. However, with a lower rating that means I stand to lose more points in losing than I would gain for winning.
That is quite an uphill battle to overcome. For carpetbaggers, they are getting what they deserve but for the rest of us, it can be a demoralizing situation.
Here are my tips for people stuck in ELO hell
1.) First and foremost a greater understanding of the system itself, can help you feel less discouraged. OK, so this guy who is 200 points lower than your best just schooled you. Take a look at his profile, maybe he was actually on or above your level.
2.) Take it as an opportunity to be humbled and to work harder at improvement. In my experience, I've only ever fallen into ELO hell at times when I was overconfident, lax with paying attention, not committed to staying in games, and in general just spamming too many speed games. Slow down, think more clearly, and work at improving. Additionally, those times I fell in rating were also often the times I spent less time doing lessons and watching instructional Youtube videos. Double down on the studying angle of things, and decrease the number of games played, especially speed games.
3.) When in ELO hell, do NOT UNDERESTIMATE YOUR OPPONENTS. This is huge. When I was pushing max rating I would only play two or three matches in a day and I would focus all my attention and energy. If you are playing dozens of matches your mind tires out. For a while, I was under the faulty assumption that this would be fine against lower rated guys, but as I realized, these "1100" rated guys actually hit peak ratings much higher than I had and could truly be a handful. If you double down on focus and study, you will probably have luck climbing out of the hole and you will probably be an even stronger player by the time you've regained your max rating, ready to push even further. In general this tip could just be read as taking your ELO Hell games as seriously as your games when you are up for a new max rating. When you sit down for, say 10 minute blitz, commit to the entire game, using your time and efforts as best as you can. I found also that in ELO Hell I had a greater tendency to bail early from games where I had fallen behind, forgetting that many matches before I've made comeback wins or at the least won on time when I was down in material but was able to fend the opponent off long enough
4.) Finally, and perhaps most importantly, is don't ever let the rating get into your head too much. It can cause you to not enjoy the game when you drop and when you are high it can give a false sense of security where you might fall behind on study or diligence in general. I can't speak for people who compete in chess for a living, but for me, chess is first and foremost....and always...about fun. For me, this has always been the primary driver for me playing and it should stay that way.

Okay guys, I am about ready to throw in the towel with chess. I thought I was a decent chess player, then I joined chess.com. I was doing okay at first, my rating ranging from 1100-1200. Then, as I started playing live more often, my ratings dropped from 1100 to 600-750! I thought playing more chess was supposed to make you better. I would like to become a master someday, butI feel as if I am the worst chess player in the world. And by the way, I can hang with people with ratings up to 2000!
You'd do good to be honest when asking for advice, you did not hang in the 1100-1200 range at all given you lost all games except for a timeout or adjudication against an 1800 player. You get what you deserve, that's how the glicko and elo system works.

I am an enthusiastic patzer. 400-900 rating depending on the setup. In 960 I am strongest.. I think that is telling. Especially in fast games many players know preset patterns. If you like it, like it. If you do not, don't. Anyone cocky about their skills in one thing are probably lacking in many others, enjoy yourself.
The problem is that blitz chess is fun, long chess not so much. Do an hour of tactics puzzles everyday and you can get back to 1000 in a few months.
Think out all the moves to the solution before you move your first piece. If you miss it, understand why the solution is right and you were wrong.

Please don't listen to Peppinu. Anyone over the age of 40 or so who starts chess is unlikely ever to reach 1000 anyway. But since he's master-level, he can't understand this.
Peppinu makes these sorts of comments a lot, and it's reminiscent of Kasporov_Jr, but because of the fact that he is titled, no one from chess.com will enforce the rules and punish him for his obnoxious comments.
Anyway, as for the OP, I recommend to analyze the hell out of every position you get before playing a move. Your goal should be never to be surprised by a move your opponent makes. After the game, do postgame analysis and be thorough!
Yes, I recognize the OP may not be on chess.com anymore, but other players in this rating range might be, and I take very high exception to the crap that comes out of Peppinu's mouth considering the fact that there are a lot of people in those rating ranges and it's very frustrating to improve at that level.
Look it's about being practical. If you are stuck at a rating of 600ish after a few months at chess, the plain truth is you must have very little natural aptitude for it. You are unlikely to reach satisfying milestones and play games of a level you can reasonably be proud of. Fair enough if you just enjoy pushing wood there is nothing to stop you but if you desire a sense of achievement in your pastimes it might be worth looking elsewhere.
A chessplayer who is stuck at a rating of 600 is like a gardener who will never grow any plants successfully...What is the point?
I see the OP had long left chess.com. He seems to have followed my advice before I even wrote it
You're making the assumption that the material was learned or taught well. You'd be a terrible nuclear physicist if someone told you that 1+1=3 and you just tried to wing it from there.

Yeah.....that link doesn't look at all suspicious.....

I would seriously consider another hobby, if you have tried chess for a few months and only got this far.
I was thinking about this in the shower and came to the conclusion that chess players are by-and-large stupid.
I'm not trolling here but consider any other pastime and does skill relative to professionals equate in any way to enjoyment?
Billions of people every year kick a soccer (foot) ball. If everyone quit after three months if that weren't playing rep soccoer or on a semi-professional team where would soccer be? Right where chess is. Russia vs China in the world cup after Norway's team with one player on the field is knocked out.
Soccer, baseball, hockey, sailing, curling, jiu-jitsu.... The list is endless but only in chess do people quit after not attaining some arbitrary online standing in a ridiculously short time span. Most people are happy just to learn a new skill and practice it in an inviting community.
No wonder almost no one can make a living at chess.
