Aggressive openings


The opposing player can easily stop any aggressive intentions.
Take the Kings Indian Defense. Known for being aggressive, and especially the classical, Mar Del Plata. But White has lines that can blunt Black's attack in a variety of ways:
1) Aggressively attacking Black himself via the Four Pawns Attack
2) Clogging up Black's Kingside with the Petrosian Variation (7.d5 and 8.Bg5 instead of 7.O-O in the classical)
3) Stopping Black's attack by slow-playing it - Fianchetto Variation.
You cannot force there to be aggression available to you.

"What are the most aggressive but ideally sound openings?"
++ Who were the most aggressive players? Tal, Fischer, Kasparov.
What did they play? Sicilian Najdorf and King's Indian Defense as black, Ruy Lopez as white.
That fits both criteria aggressive and sound.

I can relate to that.

I'll tell my own experience:
Scandinavian Qa5, unless he decides to bore you with 2...e4-e5, and they do (1750-1900 rapid, here, chess.com), your queen cruiser drives them nuts. If you can land it on a stable but active square, psychologically you already won.
If you don't mind all the sidelines, Sicilian Kan, White's knights stand stupidly ever after in the center, all your pieces are easy to develop except the g8 knight (as far as I remember, I may be wrong), so 5...Nf6 is practically better than other 5th moves.
Evans, Cochrane, Falkbeer Countergambit Old e5-e4 line.
You Can refute the Evans by playing the unearthly Qd7 - blocking your bishop, and you Can refute the Cochrane with the extra-boring Kholmov Gambit. The old Falkbeer is also refuted, but your chance of meeting a refuter is 2%.
Of course, it all depends and how much you assume your opponent will know, if my opponent were a computer I'd play a Stonewall or a Colle-Zukertort.

The most fun one, Anand has played it, and yes... your queen's bishop is right on track -b7!
Also fun against d4 is King's Indian Defense against the London System

, QGD Marshall Defense (1. d4 Nf6 2. c4 d5), I remember it was hard for me to face when I played the QG, the two knights on the queenside can operate similarly to what they do in the Alekhine's Defense, it's hard for White to grab the center sufficiently with those knights.
You can also play the "Alapin knight":

I have my own invention against the English Opening, it works okay, and is computer-approved.

Try Vienna Gambit, kinda risky but if you know how to play it properly, you'd end up with a tactical advantage by the end of the opening.

You can follow GM Smirnov on YouTube or the e4 (and b3) course of GM Adhiban Baskaran - aggressive GMs, and they teach. GingerGM has cool ideas, mostly as a 1.d4 player or a Classical Dutch player.
* GM Smirnov often takes ideas from Kasparov.

your queen cruiser actually makes me very happy. It allows me to get a few tempos and be further ahead in development than you are.

Try London System for white.
some people here want to enjoy chess, so i wouldnt recommend that.
I’ve been very bored of standard chess lately but love to play riskily/attack, often even if unsound. What are the most aggressive but ideally sound openings?
I currently play the traxler and also enjoy playing into the fried liver/traxler if my opponent is black. I just don’t want boring games as openings like the queen’s gambit bore me to death (I recently started learning the accepted variation, love to premove dxc4).
Thx in advance.
