Most Aggressive Openings & Defenses for Beginners (300-900)

I am an Italian Game user and wanted to learn more tactical concepts and ideas in different positions. However, I'm not very good at memorizing lines ;_;
For white, I was recommended:
- Evans Gambit (I used this for the first time and successfully checkmated the opponent in move 16 0o0)
- King's Gambit
- Danish Gambit
- Ponziani Opening (I'm a little iffy on this since there's a specific way the opponent has to play, but i could be wrong)
I do not have an opening for black unfortunately, I've just been using principles and it kinda sucks when you're going against people with mainline openings and tricks. ;-;
I was highly recommended to use Scandinavian as a beginner, but.....i feel like everyone knows how to deal with Scandis and trap them becuz of all the Wayward Attacks we experience.
I tried using King's Indian, but this was too peaceful (felt like london system for black). Everytime I use this defense, it's like letting White take up the space and get pinned on one side of the board. Becuz of this, I really don't like King's Indian.
I tried using Caro-Kann, but thats only if White plays at a certain way and I know that wont always be the case. It's hard for me to grasp the concept and ideas of this defense as there's no resource to explain every move/variation. Also sometimes, my opponents would keep putting me in a fantasy variation ;-;
Lastly, I was told to stay away from Sicilian as a beginner because it is highly complex to learn.
So what are good aggressive openings for beginners, especially d4 openings and black defenses?

Hmph, the Classical Sicilian doesn't require theory; it demands adaptability and an aggressive instinct. The only theory I need is the theory of domination. I don't waste time with intricate plans and fancy strategies. The Classical Sicilian is raw power and the art of dismantling opponents without the need for convoluted nonsense. Just play e6 and d6, but never allow e5. You might even place your bishop on g7. Play on the queenside and throw your pawns forward, do it in the morning, do it in the evening, do it through the night! Place your rooks on the queenside as well and crush your opponent like a maggot. Just don't play e5 as it weakens the d5-square and creates a backwards pawn on d6.

The King's Indian defense? It's like trying to build a sandcastle against a tsunami. You throw your kingside pawns and hope for some miracle, but guess what? I am that force of nature, and your feeble attack won't even be a footnote in the annals of defeat. So, you can study your fancy strategies, but when you face me, it's just another game lost in the storm.

Play the Gigachad Czech Benoni instead:

The Ruy Lopez, huh? It's like trying to straitjacket a lion – too confining for the likes of me. I don't waste my time memorizing endless lines; I prefer the chaos, the raw essence of combat. Ruy Lopez might be for the scholars, but I'd rather dance in the uncharted territories where theories crumble, and instincts reign supreme.

If you are an Italian player look into the knight attack. This leads into the Fried Liver (which is a free win at your level and hyper aggresive), Traxler (just take pawn with your bishop instead knight), Ulvestad (you will see it rarely, just return bishop to stating square). and bishop check line (you have won a pawn, and now have to play solidly for the rest of the game, where you retreat the bishop to is your choice but I prefer d3).
Also you can just play a Caro style set up for everything as black even if your opponent goes c4 or d4 (If your opponent goes for queen's gambit you will be playing a Slav). It is pretty solid in most cases, and easier then committing to multiple openings with black with differing pawn structures.

As someone comfortable in the Italian, maybe try the Jerome?

Also, I don't play the King's Indian because it is the most aggressive opening for Black. I don't know how you have been playing it, but usually it transitions into a mid game battle where you are pushing your king side pawns in a pawn storm while your opponent is doing the same on their queen side and it is complete chaos that results in crazy sacrifices. If you like to just stay put and do nothing, play the French instead.

I've nvr heard of the Jerome Gambit 0_0
I just looked it up and it says that it's an extremely aggressive version of Giuoco Piano!!

I was looking for a defense similar to openings like Italian game where it focuses on beginner level aggressive attacks. But instead, an aggressive opening for black where we attack f2 square or some other attacking ideas/concepts that can be good for beginners.

You can play Caro-Kann against anything????
Where can I learn to do that? Usually you need your opponent to do e4 d4.

It is not explicitly the Caro-Kann, but the pawn structure that results when black plays c6 followed by d5 is viable against mostly everything white plays. Most of these non-Caro positions result in the Slav defense. You generally develop your knights first then your bishops and then castle. You can try looking through different black set ups for c6 then d5 with https://www.chess.com/analysis?tab=analysis, most variations you can think are not bad for Black.

The beauty of playing a King's Indian at a sub-500 rating, and sometimes higher, is that you get opponents that see your passiveness and over extend their pawns. It becomes a "fish in a barrel" scenario.

I don't think such an opening exists for black. Maybe some lines of the Petrov where you attack f2 with the bishop and knight? But that relies on your opponent playing incredibly poorly, also you can only play the Petrov against the king's pawn opening.

It was a meme opening awhile back on the Chessbrah stream. It's bad according to the computer for White, but if you know your opponent is expecting a peaceful Gucci Piano and you want to take them out of the comfort zone, it's an option!

In any case, it's aggressive and tactical! A bit too much for my taste.

Dayum ;-;

@1

"Italian Game" ++ Good.

"not very good at memorizing lines" ++ Memorizing is not necessary.

"Evans Gambit" ++ Almost sound.

"King's Gambit" ++ Bad.

"Danish Gambit" ++ Bad.

"Ponziani Opening" ++ Unusual, but OK.

"I do not have an opening for black" ++ Black is more important than white.

"I've just been using principles" ++ Good.

"it kinda sucks" ++ No.

"Scandinavian" ++ Subpar, but OK.

"King's Indian" ++ Risky, but OK.

"this was too peaceful" ++ No. King's Indian is most aggressive. It was the choice of aggressive players like Bronstein, Tal, Fischer, Kasparov. Look up their games.

"White take up the space and get pinned on one side of the board."
++ But black gets a virulent attack.

"I tried using Caro-Kann"
++ Solid, but passive. It was the choice of positional players like Petrosian, Smyslov, Karpov.

"putting me in a fantasy variation" ++ No need to fear that.

"stay away from Sicilian as a beginner because it is highly complex to learn"
++ Yes, Sicilian is complex and yes, Sicilian is sharp.
Grandmaster use it to play for a win with black, at greater risk of losing.

"So what are good aggressive openings for beginners" ++ Stick to your Italian.

"especially d4 openings" ++ d4 is more positional and slower than 1 e4. The reason is that after 1 e4 white can usually follow up with d4 at some point, as Qd1 supports it. On the contrary after 1 d4 white usually cannot follow up with e4 and has to settle for e3 and a more closed game.

"black defenses?" ++ Simplest and best is to defend 1 e4 e5 and 1 d4 d5.

That's wrong, the Slav is not the same opening, nor does it encompass comparable plans. In addition, you can also easily transpose into a Carlsbad structure. 
 
 

90% of beginners misplay the King's Indian Defense because they rarely have much room to maneuver and cannot yet properly assess king safety to attack on the kingside.

The Ruy Lopez is the worst opening to pick as a beginner because it's closed and involves a lot of maneuvering. As soon as it gets tactical, you will lose because you aren't used to open positions.

Then you can directly abort any black game. The best alternative is the Classical Sicillian, because you often get a similar attacking setup on the queenside against White's king.
