extremely general advice for beginners vs better players?

And possibly learn the difference between fluent and fluid.
aww common man why ya gotta hate on meh english i will take a look at this paul morphy guy. i looked it up and fluent can also mean pretty much the same thing as fluid lol

I just looked at one of your games. My advice to you:
*Don't let your opponent take your stuff for free
*If you can take something for free, do it
*Check each of your opponent's pieces before you move, and think, how can they attack you?

Cherub gives great advice. And I would say that the reason better players are better is simply because they know more (and they may also have more natural talent for spatial reasoning and strategy, but it's mostly having learned more of the right things).
But very generally, you probably just need to learn the basics of how to succeed and learn as a beginner. Start doing tactics. Learn the thinking that needs to go in behind tactics and then practice practice practice. I'd also read over basic opening principles and what you should be accomplishing with your first 10 or so moves. Study endgames and checkmates. I'd also look into the "what now?" that a lot of beginners face when they reach the middle game.
There are a lot of great books and even lessons on here that can help you study all of these aspects of chess. Search through the forums with something like "beginner books". The very first book I went through was Bruce Pandolfini's "Beginning Chess". It's just 300 very basic tactics that might be too easy for you but he gives a really great overview of tactical basics. Right now I'm going through Pandolfini's "Weapons of Chess" and then moving on to Silman's "How to Reassess Your Chess".

I haven't played in years but i've decided that I want to re-try picking up chess because I felt like everything around me was rotting my brain. Im interested in any advice that might help me against players who are clearly better than me, as I seem to have a tendency of trying to keep my board as fluent as possible but then when it's too late I realize I really got myself closed off. Maybe im just too reckless with my pieces hehe.
While the e-thugs posture themselves for an online tussle, this may help you.
The basics of each phase of the game
Opening:
Follow the Opening principles:
1. Control the center squares – d4-e4-d5-e5
2. Develop your minor pieces toward the center – piece activity is the key
Ø Complete your development before moving a piece twice or starting an attack.
Ø Move pieces not pawns.
3. Castle
4. Connect your rooks
Ø By move 12, you should have connected your Rooks, or be about to do so.
Middle game:
When you have completed the Opening Principles, you are now at the middle game. Now you need to formulate a middle game plan. The middle game is a very complicated part of a chess game. A simple way to develop a middle game plan is to perform the following steps.
1. Scan your opponents 5th, and 6th ranks (3rd, and 4th if your black)
2. Look for weak pawns, and or weak squares.
Ø Weak pawns and squares are Pawns, and squares that cannot be defended by another Pawn.
Ø Knights are excellent pieces on weak squares.
Ø When deciding on weak squares, and weak Pawns to attack, the closer to the center the better
End game:
Start with the basics:
1. Learn basic mates – KQ vs. K, KR vs. K, KRR vs. K
2. Learn Opposition, and Key Squares
3. Learn basic King and Pawn endings
Pre Move Checklist
1. Make sure all your pieces are safe.
2. Look for forcing moves: Checks, captures, threats. You want to look at ALL forcing moves (even the bad ones) this will force you look at, and see the entire board.
3. If there are no forcing moves, you then want to remove any of your opponent’s pieces from your side of the board.
4. If your opponent doesn’t have any of his pieces on your side of the board, then you want to improve the position of your least active piece.
5. After each move by your opponent, ask yourself: "What is my opponent trying to do?"
thank you for everyone's input, I am especially excited to utilise the pre-move checklist Diakonia posted as I usually only ever focus on a couple of these things at a time and forget about the others. I understand that studying and practice are the most important thing and I appreciate the material that has been suggested.

Above all, remember to keep it simple. Don't try to overload yourself with knowledge/thinking algorithms. The pre-move checklist is correct, but first, you need to practice noticing if your pieces are hanging / your opponent's pieces are hanging. And then once you develop better board vision, or at least develop a thought process that detects these basic things, then you can advance more.

One of the worst things, in my opinion, that beginners develop is a large, bloated, and inefficient thinking algorithm.

Watch the Dan Heisman videos. They are not on this site but they are on International Coke Club--We're not allowed to mention other chess websites but you get the drift.
