Openings against e4 and d4 as black

Hello :)

So, I need an opening as black against e4 and d4, and I'm i very aggrsive player. Can someone help me?

well, i'm just asking, rmurray... Why so mad?

I think Bassusour was just asking for a hint, not for a deep positional analysis.

You could check out Sicilian or Ruy Lopez and thieir variations against e4, Albin countergambit against d4 ... that's what i like to play ...ofc there are many more attacking openings for black, you need to be more specific with white's moves if you want more accurate answer...

In general follow the basic opening principles and you should find yourself in positions you like, more often than not.

for e4 do d4 (scandivanian defence)

for d4 nf6 

1.e4  play the najdorf

1.d4 play the KID

You shouldn't deal with openings yet. Follow the basic opening principles, and you will have a fine position out of the openings. It is much more important for you to play slower games, and learn chess strategy, tactics, endgames. 

But you should start your games with 1. e4, and play 1. e5 against e4, d5 against d4. 

First off, I believe there is no such thing as an aggressive opening. Every opening can be equally aggressive with correct play. However, I do suggest you play openings with similar structure and group them into families. 

i.e. Caro-Kann (1. e4 c6 2. d4 d5)and Slav (1. d4 d5 2. c4 c6)

i.e. Winawer French (1. e4 e6 2. d4 d5 3. Nc3 Bb4) and Nimzo-Ind (1.d4 Nf6 2.c4 e6 3. Nc3 Bb4)

i.e. My personal favourite, Nimzo (1. e4 Nc6) and Queen's Gambit Decline Tchigorin Variation (1. d4 d5 2. c4 Nc6). I think this is an aggressive one as it power-attacks the d4 pawn. 

Maheshroks makes a good suggestion too to play Scandinavian 1. e4 d5, and although 1. d4 Nf6 is really broad, I think the Budapest Defense has similar ideas (hitting the centre pawn immidiately) 1. d4 Nf6 c4 e5. 

Now that Theres some ideas, try rmurray's advice - go find the one that your happy with!

P.S. Gambits looks aggressive but may not be always sound. 

learn only caro-kann defence well which can you play against both e4 and d4.

Uhm, the Caro-Kann is not a d4 defense.  If you are referring to mimicking the moves c6 and d5, that's the Slav, and the ideas in the two defenses are nothing alike!  About all they have in common is they are positional in nature.  The OP is asking for agressive.

Like the second post says, you need to try them out and see which one makes the most sense to you.  Telling you what defense to play is like forcing a baby to be right handed instead of left handed instead of letting him or her establishing that naturally.

I can give you a list of openings that are agressive in nature, but you need to ultimately make the decision yourself:

Agressive Defenses to 1.e4:

- Sicilian Najdorf
- Sicilian Dragon (Very Drawish though)
- French
- Modern
- Sniper

Agressive Defenses to 1.d4:

- King's Indian
- Grunfeld
- Modern Benoni
- Leningrad Dutch
- Modern
- Dzindzi-Indian Defense

Thank for all the feedback! :D

I'll check out all of your  openings, and find the best(s) one(s) i like :)

For d4 Benko gambit and for e4 Sicilian Najdorf it is very sharp defence 

Change it to non aggressive.

My second opinion, since you are already confused. Just Play 1. e4 e5 and 1. d4 d5. And forget about aggresiveness. Don't worry you will lose and win, maybe more loses.

So don't think about winning at this stage. But you should concentrate on learning about your loses.
