aggressive opening for black

I really like playing the sort of all out attack that the King's Gambit provides.  I was wondering if anyone has any decent recommendations for black

1.d4 c5 2.d5 f5 is my new opening. I'm 5-1 with it so far

kings indian defense

traxler counter attack

albin counter gambit

budapest gambit

After reviewing some of your games, I would put your efforts into studying tactics.  An agressive opening isnt going to do you much good when youre missing basic mates, and simple tactics.

Scandinavian Defense/Portuguese Gambit

sicilian is good and a lot of players bel ow 1600 dont like dealing with the french defense- but if you get too aggressive with blsck you'll usually lose

Gunderam opening, kings indian is a bit passive. Sicilian can get a bit boring. Also, try the budapest gambit.

I advise against using the scandinavian because of the intimidating tennison gambit which I use a lot.

Kings indian passive and sicilian boring? Both are more aggressive and usually more tactical than the Budapest.

Well, kings indian is a defense, for starters. It's not your run-of-the-mill choice as an aggressive opening, and yes, sicilian can get boring - especially playing against people who only know a few lines.

That's the Clarendon Court.  More provocative than aggressive.  It seems to be begging for punishment, but Black does have resources to make it dangerous to just go after.  Normal, sane play by White makes Black's life difficult.

See, this, this is how you troll opening threads correctly.  Make a note, yellow smiley face guy.

All openings from black are defenses. KID happens to be an aggressive one. Also the sicilian as a whole is played for tactical counterattack possibilities.

I don't agree. Defense and attack are two different aspects of two playing types.

latvian gambit (king´s gambit reversed)  1.e4 e5 2.Nf3 f5

and dutch defense /modern defense  1.d4 f5    or 1.d4 g6 ( you can transpose tu KID but without the move Nf6! you can play instead Nc6 or Nd7 to launch  e5!        / 1.e4 g6  , it´s a good idea avoid 1..f5 with the move 1...g6 if you want to avoid all gambits and sidelines in dutch defense.   Instead you must study modern defense . 

1.Nf3  f5     and now if  this popular gambit comes 2.e4  you play 2..e5! trasposing to latvian gambit    2.d3 d6 3. e4 e5          

1.c4 e5!  (always try to play e5, if you can´t , play f5 )    

1.b4 c5! ( i recommend you analyze this tricky line for black ) 

1.b3 e5!

No, every opening from black is a defense.

Najdorf Sicilian is the opening of champions but can get a little complex. I find Nimzo-Indian to be an aggressive choice for black that leads to a fun tactical game.
