What should be the first 2 openings I analyze and learn?

I don't know any opening very well but I want to learn an opening deeply and start using it in my games. I want to learn one aggressive and a passive/defensive one. Any suggestions? 

Attacks, I guess. I am not very sure. 

This is the easiest for you and you can be very solid or be agressive:

That was ages ago and now I know how to properly defend against that. I am asking for openings, not for you to criticize my current openings.

The four knights is always good but why don't you experiment. Alot of openings are dependent on your opponent reply

This is my opening skill set.

opening the lessons & puzzles up.

1.  you should consistantly play whatever opening you choose. Lots of videos on chess.com to help u decide and grow. Learning becomes easier with quality advice and repetive practice.. in my opinion.

Italian Game! 

Whatever you want really. I think if I was starting out again I would want to first learn the classic e4 e5 openings like the Italian game and ruy Lopez, and the d4 d5 ones Queen's gambit and so on

Try learning the italian game, may seem passive but becomes great when you learn how to attack in italian game.

Learn openings last! Start with the endgame, learn a lot about the middle game and for the first part of the game just follow the so called "golden rules":

Start with a center pawn e4/d4

move the knights bevor the bishops

castle early (and most of the time to the kingside)

don´t move a piece twice in the opening

connect your rooks and go on into the middle game.

If you just would have a look at the lessons here in chess.com you would notice, that most of them (think 95%) are about things who happens in the middlegame or endgame. Taktiks like pins and forks, pawn structures like chains and ilands or rules in the endgame like rooks must be behind passed pawns, the active king and so on. But there are only very view lessons about special openings. don´t forget: Openings teach you openings, endgames teach you chess (Gerzadowicz)

Not all openings lead to a sharp early fight. There are many systems in which the opening of lines and/or contact between enemy forces is postponed, openings that follow the form of "build-ups" and where it is necessary to foresee or know the problems that may arise dozens of moves ahead to be able to place the pieces and pawns properly. 

Learning and playing mainly one opening is important for a beginner.

The problem with giving rules about where to castle is that the player is always required to know how to evaluate positionally, in the sense of visualizing the best chances of developing an active play for both sides, and even the speed and strength of such activity. Thus, castling accommodates such an evaluation and does not work independently.

How do you get better at chess? By playing games to later analyze them, find the mistakes you've made, and learn what you need to avoid repeating them.

Playing games or learning strategies and tactics through videos, courses or books helps as long as they are components of the above. Otherwise, you learn a lot of things that you don't put into practice and then forget, while you keep making the usual mistakes and your results don’t improve.

@Marie-AnneLiz: I agree and disagree with you. Most of the things you said are right. Shure, analysing your games is important, but it should be a constant hermeneutic circle with: Analysing games (not only your own!), learning prinziples of the middle game as well as the endgame, learn tactics, learn pawn structures etc. etc. and analyse games (not only your own...) on a higher level then learn tactics and so on.... And learning and playing one opening is ok, but one should better start with some opening shich is following the golden rules, not something like the english opening I.e.

And the rule of castling.... well, EVERYTHING in chess depends on the position and so on, that is not a great argument against the rule of castling early and to the kingside. There are reasons, why so so many more games were played by castling kingside then by castling queenside or even not castling at all....

And one important thing we forgot both. Something that is said here in the forum over and over again: Play longer games! With more time to think and to remember everything what you learned up to now you will play better and this rules and ideas and tactics and everything will sink deeper in ones mind, and if that happened, one can play quicker games with less time to think.

When I was U1000 I enjoyed the Pirc Defense. I think it's a good "first opening for black" to learn. It's solid, it can be explosive counter-attacking. you can play it like a system and get away with it pretty much every time at U1000 level, and if your counter attack dosen't work out, well, it teaches you to defend, find resources and not panic from getting attacked.

With White: Danish Gambit is awesome at even U1600... I stopped playing it because people have tricks against it, but at U1000, even the "safe" version of the Danish Gambit (where you gambit only one pawn) is really great, and teaches you the value of development as compensation for pawns or even pieces...
