Against the Sicilian, the Open Sicilian (2.Nf3 and 3.d4) is easily the most open and the sharpest. And the best.
Sharp replies for white to semi-open games
I need to ask you another question, versus e5 I usually play Göring Gambit, usually transposing onto Danish Gambit, is there any opening that is more aggressive or combinative?
After reading GM Gserper's column I liked all the openings and I'm having trouble deciding for one. Among the others I like the gambits: Scotch, Evans, Göring, Danish and King. Which one is "better" for my purposes?
PS: I've tried the Smith Morra Gambit, what an opening!

Definitely use the Smith-Morra Gambit against the Sicilian if you like gambits.
Against the French, check out the Alapin Gambit - 1. e4 e6 2. d4 d5 3. Be3!? dxe4 4. Nd2 Nf6 5. f3 exf3 6. Nxf3
If black declines the gambit with 3. ... Nf6, then 4. e5 gives you a nice space advantage, and transposes to a favorable line of other variations. Just play for a king side attack at that point.
Against the Scandinavean, you can transpose to the Blackmar Diemer Gambit: 1. e4 d5 2. d4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3
Against the Pirc/Modern, I prefer the 150 Attack: 1. e4 d6 2. d4 Nf6 3. Nc3 g6 4. Nf3 Bg7 5. Be3 with the idea of play Qd2 and O-O-O. Then you play moves like Bh6, h4, and h5 to open the h file and attack black's castled king.
Just remember that if black plays c6 and b5, then you can't really get away with castling queen side and attacking on the king side, because black has a decent counter attack on your king, so play Bd3 and castle king side in that case.

Hi everyone!
While practicing chess I've noticed that I feel comfortable in tactical open games, so I wanted to study openings that lead to that situations, I like gambits since the game they lead is very romantic and spectacular. Thats why as white I start with e4.
The best for me is when my opponent answers e5, but when he doesn't leading to a tactical and aggressive play in not that easy. I wanted to ask you if you could suggest me some sharp and aggressive openings after the most common replies to e4 such:
c5 (Sicilian), e6 (French), c6 (Caro-Kann), d6 (Pirc), or others that I'm probably forgetting.
Against Sicilian I play the Wing Gambit:
But I've recently red that it's not theoretically correct.
I'd like the openings to be playable while as much as aggressive as possible. I found a plenty of that kind in GM Gserper's column, but he was talking only about open games, so the question is: How could I lead a semi-open game to a tactical, sharp and aggressive one?
Thanks in advance!
