Good defense for an attacker?

 Hmmm....... a class player with MANY BRILLIANT TACTICAL WINS ??  Gee, I would like to see some of those... 

The Petroff is not an agressive defense vs. 1. e4.  Good yes, sound yes, sidetracks Whites plans, yes but not agressive.  Try 3... f5 in the Ruy or the Marshall but you must prepare for many different lines.  The Sicilian is popular because there are not many responses to 1. e4 than allow sound counterplay early.  Assuming you do not like the cramped nature of standard responses to e4 (Caro, French, Pirc, Alekhine, etc) you should look at a response based on 1...e5 as your best chance for an agressive response.  It will take more work but will be something you can use for your entire career. 

The Dutch is something I've considered. Don't you think the Benoni would hold as much surprise value?

Of course ...c5 isn't the only aggressive move (and this is excluding black gambits, because they're usually dubious). 1...e5 can be aggressive and open, it all depends on what variation is played. There are sharp variations against the ruy too, and if your opponent just plays Bc4 and simple development you can bank on easy equality and outplaying him later.

I often play 1...e6 with aggressive intentions, just in different ways. It's closed and involves maneouvering usually, but black very often gets counterplay in either the center, queenside, or sometimes kingside in some form, and the structure is always solid. And it's flexible. Lines from the french branch off into both solid and sharp lines, which your opponent has to be ready for, and quick blitzkrieg attacks aren't an option for white.

The "open" sicilian is really only semi open since there are still plenty of center pawns. It's still possible for white to do a dangerous piece attack, but at the same time black's structure in many lines lets him get away with slow development, many pawn moves, and even delayed castling. He just has to be careful.

1. ...e5 can give the Black aggressive play but it somewhat requires the White to co-operate. The White can usually keep the game quiet if they want to, so you need to be prepared also to play more positionally when needed. I think that will be true of most other Black defenses as well. (Even the Sicilian has lines like the Alapin.) Alekhine's Defense seems almost bound to lead to a fighting game, and it takes some nerves to play it as it's very easy for the Black to find himself facing a devastating attack if they are not careful. Against d4, I think the most aggressive defenses (or at least, the ones that give you the best chances to play an aggressive game) are the Dutch and the KID.

i enjoy the one when they dont trap the queen due to you could move it a lot and not be very deviloped but he losses most of the back row and several pawns in exchanged for having a beter strucher with what he has

You don't appear to play any games here either. Anyway...

Can you give examples of gambit lines for Black in the Petroff ? I only know of gambit lines for White there. 

 Yes, you ARE a class player, class C to be precise according to uschess.org , anyone can go there and look up your rating and see for themselves......

e4 e5 is best

against d4 King's indian

Here's the way I see it:

Good attacking/counter attacking defences to 1.e4: Silicians, Marshall Attack, French, Pirc, Alekhine's defence.

Mediocre counter attacking defences to 1.e4: Scandinavian, Schliemann defence.

Bad aggressive responses to 1.e4: Latvian gambit, Elephant gambit.

Good attacking/counter attacking replies to 1.d4: KID, Semi-Slav, Modern Benoni, Leningrad Dutch, Gruenfeld, Benko Gambit, Note Boom.

Mediocre counter attacking defences to 1.d4: Stonewall Dutch, Classical Dutch, Blumenfeld Gambit, Budapest defence, Hennig-Schara gambit. 

Bad replies to 1.d4: Englund gambit, Albin counter gambit (this may be mediocre).

I may have missed some aggressive/sharp openings there, so forgive me. The way I ranked them is just my opinion and is not necessarily correct.

 Look, anyone can go to uschess.org and look you up and your tournies and the results. you played in 94 ( 1 ) , 95 (2), 99 (2) , 2001 (2) and 2004 (1) .  the number in parenthesis is the number of events you played that year.

The one you mention in which you say you won every game was a 5 round event, you forfeited first round apparently then second round is marked U ( unplayed ) and its true you won 3 games and all 3 of your wins were against players UNDER 1320 !  BIG DEAL ! 

Which NMs in/around Atlanta do you know ?  Your overall record is roughly 50% and against weak opposition.

lol leave him alone. maybe hes a strong player, maybe hes not. does it really matter? is the outcome of any serious matter actually going to be affected by others logically deducing how strong he is? challenge him to a game, if you care to know so much... know what im sayin'? besides, 2004 is 6 years ago. plenty of time to improve your chess greatly.

anyways, my opinion. against e4, excluding sicilian: give the alekhines a try, but learn some theory. its easy for either side to screw up rather badly in any of the main lines. and give ...g5!? a try against the four-pawns attack. loads of fun, and some of the sharpest play ever. also, the damiano defence. gives black excellent winning chances

against d4: leningrad dutch or KID, and if your feeling raunchy, the budapest. ...e6 is an odd reply, certainly ok, but if your trying to counterattack a nimzo-indian type system, which it might easily transpose to, isnt known for giving black great attacking chances early on.

[...bursts into tears]  I KNEW IT!...  [spends remainder of afternoon sobbing.. also, rum]

It was your idea though to claim that you have 2300 strength, for which we have no evidence whatsoever and are free to doubt it. Also I'd like to see those gambit lines for Black in the Petroff. Even any sharp tactical lines where the Black gets the tactical opportunities would be interesting to see.

You are a C class player , under 1600.  I dont tolerate arrogance well , even if the arrogant person is a super GM , if they are just a C class player then I really cant just ignore it......  You didnt give me the names of the NMs in your area..... I can certainly contact almost anyone in Atlanta chess .  I know many of the people that were playing in those events you played.  Murphy Clay, David Vest, Lester Bedell, Stephen Csukas...... etc .  I grew up in Ga and played chess in Ga from 73-97 and played there as recently as May 08 in the state championship.

You also didnt tell everyone which section you were playing in , in which you said you won all your games. Do you wanna fess up now or shall I tell them ?

I suspect you like many other unrateds vastly overestimate your playing strength (and I'm guilty of that too, though I haven't ever claimed to be master level or anything in any way). You might be what you describe, but more likely not, so don't expect anyone to believe you without proof.

I would certainly not recommend the Latvian gambit as black.  It will trick lower rated players but against those that take their time and concentrate, you're going to hit bad positions where white has a clear, and very dangerous, initiative and advantage.  I would take a look at what type of attacks and tactics you're good at and go from there.  I would also look for something positionally sound before playing something with tactical chances.  If you don't control the position, usually an attack on its own is unsound.  It's also relatively easy for white to play passively.  Against 1.e4 I would SERIOUSLY reconsider playing the Sicilian.  Yes, many of the positions are sharp and, with incorrect play from Black, you're going to get handled, but a thorough study of the ins and outs and you'll find yourself with incredible attacking chances.  I'm not a fan of promoting the Scandinavian Defense because it brings the Queen out on move two, but not all of the lines favor White, and it signals a fight early on.  For a fight against 1.d4, I would look at the KID, the NID, or the Black Knight's Tango, because of it's transpositional natures.  I wouldn't go with the QID, it's been my experience OTB that it's extremely drawish, but it does have it's chances.  Whatever defense you choose, the key to having any sort of attacking chances is to know your stuff.  Study the defense until the key lines can be rattled off in your sleep.  The move order alone isn't going to give you the tactics you're after, it's knowledge of the strategies and why the moves are made that are going to help you obliterate your opponents.
