Sharp openings

I'm currently looking for a sharp opening repertoire that isn't too unsound (although some options are a little strange). I'm doing this because I just want to improve my tactical ability, not necessarily to shift my style of play. Here's what I've got so far:

As Black:

vs. 1. e4

 1...c5 2.Nf3 g6

vs. 1. d4

 1...Nf6 2. c4 c5 3. d5 b5

As White:

1.e4

vs. 1...c5, I don't have anything yet

vs. 1...c6 2.d4 d5 3.exd5 cxd5 4. c4

vs. 1...d5 2.exd5 Qxd5 3.Nf3 (I know it looks a little odd)

vs. 1...e6 2.d4 d5 3.Nc3

vs. 1...e5, I got nothing here yet either.

The problem I have is that I'm at a loss for finding sharp openings for the two most common replies to 1.e4. I know the sicilian is full of sharp ideas, but a lot of them have WAY to much theory behind them for me to even dream of learning, and 1...e5 is inherently a positional move. If you know of any way to fill the gaps in this repertoire, I'd really appreciate it. If not, that's okay too, have a nice day anyway :) 

My Opening rep:

1.c4

Against

1.e4 d5

1.d4 Nf6

After that its all winging it

If you equate "sharp" with "tactical" then I'd say the King's Gambit is your answer to 1. e4 e5. It's more tactical than positional.

I don't have any suggestions for your taste for the Sicilian. The Sicilian is already as sharp as can be so you can't make it any sharper. If you don't like learning loads of theory, maybe you don't really want a sharp opening after all, since it's likely that the way players try to win in such openings is by outbooking their opponents. Just my thoughts.

      KING'S GAMBIT
(1 P-K4, P-K4; 2 P-KB4)

THE King's Gambit, the darling of the romantics, is a swashbuckling
opening synonymous with attack, sacrifice, and an exciting open game.
The Chessplayers' Manual by Gossip and Lipschutz (1874) devotes
237 pages to the gambit without arriving at a conclusion! With the
coming of regular clock tournaments its popularity began to wane.
The Baden 1914 and Abbazia 1919 gambit tournaments, which proved
that Black could maintain a positional edge by returning the pawn at an
appropriate moment, all but caused its eclipse in serious chess. Despite
Black's ruthlessly precise defences, there have been sporadic attempts
to revive the gambit by "chess pirates" like Bronstein, R. Byrne, Pomar,
Fischer, and Spassky. Today it is played with a view to obtaining a
positional advantage, even if it means an early exchange of Queens,
and the question whether this is an opening of the future or of the past
still remains. But until an antidote is found to Fischer's recommenda-
tions in cols. 11 and 12, the gambit must be considered wanting.

I'm just trying to develop this kind of repertoire so I can get better at seeing tactics and I'd rather not have to really book up just to play a good game. If that's the case I might just have to play 1.e4 c5 2.c4 where we transpose into the Botvinnik english (a part of my current repertoire), but I'd rather not have to do this if I don't have to.

1.e4 e5 2.Qh5 is very sharp.

I guess "sharp variations" makes more sense than "sharp openings".And "sharp moves" makes more sense than "sharp variations"."Sharp knives" makes even more sense.

Definitely. White gets cut every time.

"and 1...e5 is inherently a positional move."

This is precisely why people need to stop obsessing over openings. 

Is positional deleted by mod CR better than tactical?!

I have to comment on the sicilian,

In the open sicilian black has to be way more worried about not being booked up than white, And believe me as someone who is not an expert anyone less than expert (and masters would say even them, or anyone that is not a strong GM) does not know how to play the black side.

so many sharp idea's against the sicilian. after a6 look at Bc5, Bg5, Be3 pick whichever one you like the plans of most.

also look up the Keres attack vs the Scheviningen (sp) it is incredibly fun to play. of course playing the yugoslav against the dragon is great.

the only open that can be slow is the accelerated dragon,

My theory is that in the open sicilian most people play both sides incorrectly but black gets checkmated when he plays incorrectly, therefore no player under expert should be scared of the sicilian

I guess I should add more clarification.

I'm looking for openings with an abundance of tactics. For example, in the slav defence, there aren't many tactics to look out for (relative to other openings), whereas in a Najdorf sicilian you have to constantly be scanning for tactical tricks. 

My goal with this whole endeavor is to add to my tactical IQ by playing games where I have to be more wary of tactics (as I have been unwisely avoiding that until now). 

And about 1...e5, I thought that after 2. Nf3, 2...Nc6, 2...d6, and 2...Nf6 all lead to positions with fewer tactics than other 1.e4 openings (of course, there might be weird sidelines and gambits, but I'm not considering these lines). 

Also, one more thing, is the scotch game worth considering?

Scotch is great. Can get very tactical very quickly!

In addition to pfren's comment about there being tactics in all openings, there are positional aspects in all openings as well.  Until you understand both, you are useless.  Either you are a tactial player, a positional player, or a chess player!

I have played games as Black with the Slav that were EXTREMELY WILD AND TACTICAL (especially 5.e4 lines).

I have played Najdorfs that were extremely positional (especially if White plays 6.Be2)

A previous post suggested the King's Gambit against 1...e5.  There are lines for Black that take the sting out of the King's Gambit as well!  I play one of them myself!

Here's an extremely positional Open Sicilian:  1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 d5.  With best play, it's a little better for White than more mainstream Sicilians, but if White expected a highly tactical game with 1.e4, dream on bro!

One player can not force the nature of the game.  Chess is like Tango, it takes two!

Youre limiting yourself with statements like "I'm looking for openings with an abundance of tactics. For example, in the slav defence, there aren't many tactics to look out for (relative to other openings)"

Find openings you like to play, it shouldnt matter how "tactical" they are.  Unless youre trying to win right out of the opening, the only purpose the opening serves is to get to a playable middlegame.

(TF #19) One player can not force the nature of the game.  Chess is like Tango, it takes two!

Sadly true, 'cuz I luv a highly tactical game....the interesting & complex positions. The problem is most players are scardeecats.

Ace #1 scareecat right here!  This is why i steer the game into "boring" waters.  It takes away a lot of the tactical elements, where i can bore my opponent to death.

Your choice against 1d4, the Benko, is mostly position play from Black.  The King's Indian, Grunfeld, or Modern Benoni are sharper.

The caro advance is as sharp as it gets
