How do I get to 2000 USCF?

Hi, I am a sophomore in hs hoping to be 2000+ by the end of junior year. I have been playing chess since kindergarten and stopped in 5th grade with an 870 rating. This past summer I have been practicing a lot on chess.com. I went to my first tourney since 5th gradr about 2 weeks ago and my rating went up to 1077 and I performed at 1211. I want to how and what I need to study in order to become 2000+. I've noticed that my opening repertoire is horrible however my tactics are decent. what shall I do?

As a sophomore, you should have learned that it is easiest to research questions that have already been asked repeatedly. You are lucky. Your particular question is asked just about every day.

Try searching the forum.  http://www.chess.com/forum/search?keyword=get+to+2000

(Ignore the first 5 posts which were made by someone who thought that the way to get different answers was to repeatedly ask the same question.)

/Besides, you already know the answer. You have been working on tactics and it helped. Now you notice that your openings are not good. So work on them for a while while you continue to work on your tactics. Your next step is not to get to 2000. It is to get to 1100.

win a lot of games until you get to 2000.

Before you can achieve expert you need to become an intermediate first.  I looked at one of your games and you still make careless beginner mistakes.  Seriously work on board vision and the different pieces' fields of control.  Ba3?? for example simply lose a bishop with no compensation and none of your other pieces controlled that square, logically meaning the bishop, who was in the black rook's field, could be taken for free:

First learn not to blunder pieces and take your opponent's pieces if they blunder it. 

              Take a left on 1800 street. Go 200mph for40 blocks. STOP!  look up,  your there.  Good luck!

Don't resort to gimmick openings that are played just to catch your opponent off guard. Play solid, main line stuff unitl you get the fundamentals of opening play under control: e.g. Ruy Lopez or QG.

And do not be afraid of playing into someone's favorite opening. There is nothing more satisfying than beating someone at his own opening.

Develop an opening repetoire that suits your style but I would recommend not playing rubbish openings like the London System. Learn opening ideas like the Ruy Lopez, QGD/Semi-Slav, Sicilian, KID, etc.

Focus a lot of your time studying tactics and endgames. Look at your losses and see which moves were blunders or weak. Also, read positional books that will help you spotw where you can improve your game.

Play lots of slow chess! You will recognize patterns more easily and thus be better at maintaining your time. Doing this, it took me about 4 years to beome an Expert.

i am not what 2000 rating player sees

but i am sure they are good at openings and memorized their openings 30 moves deep like carlsen does

chess is probably 90% opening memorization

Not true greenfreeze. Learning opening plans helps and experts may seem like they know what they're doing but they just grasp the position better.

Tactics and endgames is the way to go.

Just to let you know it will take way longer than a year to get to 2000+ and if so you have to study a LOT.

I hope to become 2000+ next december if i am very lucky.

But you could do it if you are very dedicated

Dont memorize any openings.  Play in the center and develop pieces.  Castle at some point.  After all pieces are developed then push another center pawn somewhere.  Openings are a black hole you get sucked into and you don't improve.  Like a swimmer practicing jumping off the block who never practices actual swimming.

Play rated tournament games against players at your level or slightly better than you, then go over each game with your opponent or a stronger player or a group of players.  Then annotate your own games and publish them somewhere.  Where?  It doesn't matter.  Maybe at your chess.com blog or at a blogspot blog or in youtube videos.  Publishing forces you to be honest and not to pretend that you played better than you actually did.

Practice tactics.  Also pick a single good book with a collection of master games and play thru it game by game.  Which book?  The one that you will actually read.  I used Art of Checkmate (Renaud) and Art of Sacrifice (Spielmann).  Pick one, don't get too hung up on which one.  It doesn't matter much.  Your real improvement will come from studying your own mistakes in your own games.  This is an ego-crushing process because you need to learn why you suck and tell the world about it when publishing.  We all suck.  Nothing personal.  Your moves are just decisions about small pieces of wood or plastic that relate to nothing in the real world.

Don't get hung up on trivialities in this process.  There are many paths -- you can get there.  Good luck.  FYI I am 2076 USCF, self taught starting at age 25 or so, expert within 3 years after about 30 tournaments while working full-time as a lawyer in Los Angeles.

Although later on memorization is key.
