Super aggressive opening as a white for club player below 2000?

King's Gambit.

Smith-Morra Gambit against Sicilan, 1. e4 c5 2. d4 cxd4 3. c3

London System 1.d4 Nf6 2.Bf4  or King's Indian Attack

If you're planning on playing the King's Gambit, play the Vienna Game instead. Similar ideas to the King's Gambit Declined, but completely sound, very tricksy and has the added benefit of being virtually unknown. Most 1...e5 players won't know how to deal with it.

If you play e4, there is no way of preventing the French or CaroKann.  Even here you can play the exchange variations in both.  The Vienna is wonderful.  Most Sicilan lines would be good.   

I used to play the Bishop's Opening a lot, but often ended up transposing into the Vienna. So I recently starting looking at the Vienna. Here is a miniature from a recent daily game of mine to give you an idea of how explosive the Vienna can be - Chess.com/Stockfish didn't like 5 f4 but Suetin et al in The Complete Vienna say it's "forced" - and in King's Pawn Openings you have to love it as White when f4 is forced:

Play open games as much as possible and try to introduce complications where you're able to if it's advantageous to you. Even if it's pure speculation, because the more often you do it, the more it will become almost second nature to you. The hallmark of aggressive attacking play isn't opening choice, it's the ability to read the board knowing where to strike, how to do it as well as the perfect moment. Tactics lie in nearly any position, you just have to find them. Sorry, I'm just tired of people asking for specific openings like they expect playing specific lines to automatically make them a tactical genius or something.

Also, you can try the Bird or Nimzo-Larsen. I sometimes combine them with 1. f4 2. b3 3. Bb2 and 4. Nf3 depending on black's move order. I only play it in blitz but it's usually a wild game
