In my eyes 900 is achieved when you know how to move the pieces and have some clue of how to move, developing, etc. They don;t have any "depth" of the game.
Anything above 1500 is decent for me and 1000+ is intermediate. In my opinion, "good" players are 2400+.
First piece of advice, play longer games. I know playing a 10 minute game may be "exciting" but it means you have less time to actually contemplate your position and spot the patterns that you learn by taking your time, you mention missing and messing up positions, this comes down to seeing every aspect of the board, which is harder to do if you are under time pressure, play 30 minute games, you will be surprised what you spot with that extra time up your sleeve.
Second, Focus less on studying lines, focus more on fundamentals, at this level you want to play sound and justifiable moves and let your opponent mess up. At the level you are playing at, if you are trying to pull off complex traps, you aren't focusing on the basics.
Finally, ignore people like MarkofGreatness.
Advice from a 900 is rather funny, as they usually have no idea what they're talking about. I'll give you my two cents:
-Tactics - these help your game and can honestly increase your rating quickly. Also, you need to be aware on hanging pieces on both sides of the boards. Not blundering single-handedly improves your play.
- 10min Chess w/ mixing in SOME 30min Chess - Quicker chess helps you develop systems and get more familiar with your opening. Longer time controls will develop analysis skills
- Analyze your games for mistakes and use the reasoning of why the engine preferred a move, and how it alters the position
-Middle game planning - look at some grandmaster games (agadmator covers them well) and start plan development so you know what you are doing.
- Work on your endgames - this is clean-up work and this site has Drills that can help you
With all that being said, good luck!
Thank you for the feedback, I'm not really sure how one sees the rating of posters either. Is 900 a good rating?
I'm just curious, whats up with MarkofGreatness judging from the comment about him/her? As a new person here, I've no clue what to make of that comment.
Tactics - I do just fine non-timed and catch the hanging pieces. Timed, I can miss maybe 1/3 of them that could be a game changer. Similarly, pretty much no mistakes in non-timed games. Timed, I can make some missteps that are costly. Though technically I lack the sharp checkmate ability but am improving over time.
10 vs 30 minute chess - Now I'm confused on which to do if at all. Technically I've never timed my games before but 30 minutes sounds far more accurate than 10 minutes. But I tried the 10 minute ones just to see how I'd do implementing my [weak ability for] sharper checkmates without reducing the opponent to just the king and 2 other pieces.
Analysis - I analyze everything and even diverging lines just to what might have happened. Read above and a poster was right, I over-analyze things in general.
Middle game - That's actually pretty solid for me when I'm not in 10 minute games.
End game - That's pretty solid when I gradually wear them down then checkmate the isolated king...but I'm assuming any novice can do that. My current project is to improve my weak ability to do sharp checkmates when the board is still moderately populated.
You have yet to play a 30 minute game on this site and yet you are here talking about 30 min being more "accurate". With a 404 Blitz rating from 10 min games, chances are that you're not much better at 30 min games.
To be frank(I'm trying to help you), nothing you have is "solid". You'll see it in your 30 min games; and by tactics, I don't necessarily mean hanging pieces; I mean ways to get hanging pieces, such as forks, pins, skewers as well as the mating sequences.
And no way is your endgame technique "solid"; it takes a lot of learning and principle; I highly doubt that you can even mate with two bishops and king vs king. You might have difficulty with rook and king versus king.
By the way, to answer your question about seeing rating of the posters, you just have to click their user as it shows on the forum and their info pops up, including their rating.
Lastly, I bet that you miss 75% of Tactics and you don't even know it. Chess is crazy.
