What things should a 1200 rated player know?

Cuz im 1200 and winning 1 game every 6 games so I want to improve it. I think I don't know chess tricks which a 1200 should know. So TSIA

Thanks Others?

Probably just tactics and not hanging pieces. I think it also helps trying to figure out why your opponent played something also. And playing slower games, min 60 minutes and daily would be better. Simple endgames like KQvs K or KR vs K, but even at 1500s where I am at, I wouldn't say that endgames are where games are won and lost very often.

intermediate tactics, opening principles, basic endgames

I briefly checked your game against acdclele. I'd say a 1200 should have a better understanding of opening principles and should have better board vision. Take some time to study tactics and start systematically assessing position/moves for check, captures and attacks

Then I checked you game against nitisastro. You need basic opening principles, basic tactics and learn the value of pieces.  It's impossible to keep a 1200 rating playing like this.

You need to know tactics and basic endgames.  Also you need to be very consistent of not making any silly mistakes in every single game that you play.  

I recommend you to look at tactic books so you can think several moves ahead for every move.  

100 endgames you must know, and woodpecker tactics method. 1. opening for white and 2 for black against e4 and d4. 50% tactics, 30% endgames, 20% openings.

If you have to ask the question, then you will not understand the answer

what he said+the ability to not hang pieces every 5 moves

thats really the bare bones when it comes to studying books, but as far as endgames books and tactic books go, the two i mentioned are very good.

Iv had the lucena position a handful of times.... Its not all about memorizing theroretical endgames. Knowing when your playing for a draw or a win. When the 8th or 1st rank defense works or doesnt work. Is this a win with a rook pawn, knights pawn, bishops pawn?. There are small details that matter and if you have the basic understandings youll have a better chance at drawing or winning. I treat it the same as openings....i dont need to memorize line 24 of the caro kann tal variation....i just need to know what the overall plan is for white an black.

Candidate moves and your opponents ideas and plans. Always ask yourself What are all the good things their move does for their position and what does it weaken.

eu nao estou entendendo mas eu sei que e coisa boa

This pretty much never happens. I can't recall even one example of this happening to me, not even when I played against a GM or an IM in a simul. It is extremely difficult to win or lose a game in the opening. Almost all games are decided in the middlegame.

Back to the original question, I think that typical 1200-rated players know quite enough, maybe more than they need. (This is not true for beginners, who know nothing). What 1200-rated players are lacking is not some more theoretical knowledge, but calculation skills and a good recognition of tactics.

I would suggest these things:

1. All Rules of the game

2. Basic Tactical Knowledge

3. Think up to 3 or 4 move combinations/ variations

4. couple of lines of openings that you are comfortable with

5. follow-up mid game plan after the opening is complete

Yes

Seems like you are exactly on the right track. To reach 1300 (and more) you need to do what you're doing. Haven't you gained more than 100 rating points in rapid in the last 30 days? (The answer is yes.)

I think the main problem with 1200 and below (including myself) is blunders. This might be helped with some slower games and some knowledge of some good openings.

You mean, Pirc?
