First of all, welcome to chess.com! You really can improve a lot here, especially beginners in general are able to make good progress in a relatively short amount of time.
I looked at some of the games you've played here, and I think it would be a good idea to try and go over all the fundamentals. Even if you're pretty good out of the circle you usually play in, it's important to have a good foundation if you want to improve. This will also help with understanding some of those articles :)
Other than basic "overkill" checkmates such as king + queen vs a lone king (which is a bit tedious to do in a post like this) I'd like to go over 1) Some basic advice 2) Tactics and 3) Opening principals. Oh, and just in case you don't know them, the relative value of the pieces. This is handy to know when a trade is good or bad for you. A pawn is worth 1. Knights and bishops are 3, rooks are worth 5 and queens 9. So if you trade your bishop for your opponent's rook, you've won material (2 points). If you trade a knight for an opponent's bishop, that's an equal trade (3 for 3).
Ok, so some basic advice. Playing through 2 of your games, I notice sometimes you either leave a piece undefended on an attacked square (your opponent can win the piece for free) or your opponent leaves a piece for you to take for free and you don't. Every time your opponent moves, check to see what it threatens. Your opponent probably has something in mind with each move, so look at all the new squares that are under attack.
More important than doing drills on tactics trainer is eliminating these errors in concentration... with practice though, it will become 2nd nature, and it wont take much work.
This is a position from one of your games where white has just moved his king out of check. What's black's best move here?
Instead of moving the rook, you could have taken the queen with Nxd1. (Before this, instead of moving your knight, you could have taken white's rook for free... although this is hard to see at first, your light squared bishop is attacking the rook in the corner -- this is actually a common line of attack so a good one to remember).
---------------------------------------------------
In a different game, this position was reached. Black has just moved his knight to b4, do you see what he's threatening?
Black threatened Nc2+ forking your king and rook. This may be hard to see at first, but this is a common fork. Instead you took his g5 pawn which was protected by the black queen. Black then had the option of winning either your rook or knight. (Earlier, instead of moving your queen, you could have captured his knight with your pawn for free).
So be very careful! Tactics trainer won't do you much good if you miss these free gifts (or give your opponent many free gifts).
---------------------------------------------------------
Opening principals
The opening is about control of the center and speed (or utility) of development. The center means the 4 centers squares. You want to occupy at least one of these squares with a pawn as soon as you can. The reason is that staking out space in the center gives you the freedom later in the game, to maneuver your pieces to either side of the board.
1.e4 for example, (moving the pawn in front of the king two squares forward) opens lines for both your queen and bishop to come into the game.
To move the rook pawn forward and bring your rook out is actually a common practice among beginners but it's not good! The rook is worth 5 points, and he's going up against a enemy wall of pawns. Almost any piece that attacks him will force him to move backwards and lose time...
Which brings us to speed of development. In the first 10 or so moves only move 1 or 2 pawns, (pawns don't count as development!). The rest of your moves should be getting your pieces off the back rank and into the game. 1 move, 1 piece... your army is a team, use the opening to bring them all out.
Another common error is to develop only 1 or 2 pieces and then launch an attack... but if your opponent is following my advice above (not falling for 1-movers, leaving things open) what hope do your 1 or 2 attackers have against the whole of black's army? They have no chance . So unless the opponent is threatening to win something, go ahead and bring another piece out, and try to have it influence a center square. Because it's easier to tell where knights can influence the center, it's usually good to develop them first. This would be an ideal development if your opponent lets you have it:

Tactics are also important, but I guess if you're doing tactics trainer you're already familiar with the basic motifs. This post is long enough already, so I'll stop here. If you don't know what each of the following are though: pin, fork, skewer, discovered attack, then it would be best to look them up on wikipedia.
As well as be familiar with the idea of a double attack, which is the fundamental idea behind tactics. A move that creates two threats will win you something (your opponent only has 1 move to defend!). A good example of a double attack (called a fork in this case) is in the 2nd diagram from your game, the Nc2+ attacks (forks) both your king and rook -- your king must move out of check and so your rook will be taken next turn.
Good luck with your improvement. If you continue to play games and work on these things you're sure to make a lot of improvement quickly :)
Hey there!
First off, before I start, let me introduce myself. My name is Nathanael, and I have loved--and have played--chess for many years now. However, I have always just been the average joe. Not exceptional, not aware of all the tricks and moves, et cetera. I want to improve... but I don't care about my ranking, nor do I wish to join any tournaments. I just want to get better at chess by playing online every so often.
Now, I found Chess.com by searching for, well, how to improve in chess. However, I can't figure out how to... well... improve in chess! I do the Tactics Trainer my allotted 3x daily, and I have played a few games, but what I am really looking for is a good guide or collection of guides. Looking at the articles, most assume a good knowledge of chess. I just can't follow any of it! Sure, I can see how the person gets into checkmate, but I wouldn't have any idea how to replicate it in a real game. I don't learn anything from even the "best" articles.
So... what do you recommend? How do I improve my chess to such a degree that I am actually "good"? How do I learn? Thanks for your help. :) I don't know if anyone has ever asked any problems similar to this, but I never found a similar post in my searching.
Also: I am well aware I should just "keep playing." That's a given. I'm looking for a bit more than that, haha. Thanks a lot!
