How to Achieve 1500 USCF Or higher?

I am currently 1150 USCF and really want to find a way to improve. I want to know a logical method that could make me play a good game and boost my rating. Is it openings, tactics, endgames, or psychology? Please respond.
Yes...
There is no one thing that makes you a good player. You have to learn it all.
A little at a time of course.

Simple. Don't hang pieces.

"Every now and then someone advances the idea that one may gain success in chess by using shortcuts. 'Chess is 99% tactics' - proclaims one expert, suggesting that strategic understanding is overrated; 'Improvement in chess is all about opening knowledge' - declares another. A third self-appointed authority asserts that a thorough knowledge of endings is the key to becoming a master; while his expert-friend is puzzled by the mere thought that a player can achieve anything at all without championing pawn structures.
To me, such statements seem futile. You can't hope to gain mastery of any subject by specializing in only parts of it. A complete player must master a complete game ..." - FM Amatzia Avni (2007)

My recommendation: create an opening repetoire.
Choose a pet defense against e4, and another against d4 (the two main opening moves you'll face). Choose a pet offense, too. Go with something solid, not something unsound.
After every game you play, review it with an engine to see what mistakes you made. See what you can learn from it.
With consistent practice and study, you'll see your ELO rise.
Good luck!

Also, think ahead. Before you make a move, you should think what your opponent is going to move after your move. It is similar to math. You can do all the calculations in your head before you make the move. And your move should benefit you, not the opponent.

Figure out what your week point is. Is it the endgame? opening? middle game? A certain position? Then read books do tactics on that kind of week point. But the best way you learn is from mistakes and experiance. Do a lot of tounaments that is the best way to improve. You can only do so much on your computer and in a book.
hope i helped.


Tactical puzzles are more useful for lower rated people than higher rated.
You're practicing many things at once. Not only tactics, but you're learning to look for forcing moves. Learning to see the whole board (that sneaky bishop or rook on the other side of the board). You're trying to find moves for your opponent that work against you. You're practicing visualization. Practicing analysis (when you dismiss one move and look for a better one).
By the way, blitz puzzles e.g. here on chess.com don't do half of those things for you. It's good to learn some ideas, but bad to do for hours at a time. I'd suggest something like 10 blitz puzzles (my new term heh), then a few untimed puzzles. In the untimed puzzles write out your full answer (with any variations) before checking the solution or making the first move. For the untimed puzzles you'll probably only do 4 or 5, but put a high importance on accuracy, so it may take an hour!
An hour or two of this a day for a month is not a bad start to a training program IMO. After improving your visualization and affinity towards forcing moves, for the next month I'd focus on something else. A basic strategy book for example.
