First, don't take my opinion too seriously as I only started delving into Sicillian as black, and have been dealing with nothing but Bowdler attack, lol. Also not that strong of a player at all.
Idk mate, you already realize Najdorf being incredibly flexible, and theory heavy. You say you are ready to put heavy work. You also realize if you keep going with Najdorf you would be most tenacious in long run.
All of this screams Najdorf for me. What do you plan against Alapin, Closed, etc I wonder though?
All that being said, I’ve been split between the najdorf (for long term growth and understanding of different structures) dragon (for aggressive attacks against the white king) and the classical (to get a hold of the scheveningen pawn structure, kind of a place holder until I’m good enough to play the najdorf). I have tried all of these, and recently I’ve been playing the dragon, but I wanted to get a couple opinions on different lines in the Sicilian that will help foster my growth. I want to learn how to play different structures and also play aggressively to train my calculation. I have also played the taimanov and accelerated dragon, but they both seem more like positional battles that can fall into passivity rather easily. I want to play the Sicilian to get into sharp must-win positions, because otherwise I would play e5.
The only problem I have with the dragon is that it seems like dragon structures are specific to the dragon, where najdorf has the scheveningen, boleslavsky hole and can also transpose to the dragon. I am having some success with the dragon however, im just worried about long term prospects.
Najdorf obviously hs the most theory, but will likely be most beneficial to my growth. I also think some ideas are unintuitive, but if I can get a good book that explains the ideas better (when to play d5 and how to protect the d5 square, as well as different themes in the structures) then I could probably find success.
The classical is kind of the middle ground. Only thing im worried about is that it can be considered too solid of an opening, and the gxf6 structures are unique to this opening, so im not sure if this is going to be a good option or not. I’ve heard it finds success at the top level though
What do you guys think? Im willing to put in the work if it will be beneficial to me in the long term, and im not a big fan of openings that are only useful to a point. I play almost all mainlines because they are the most sound and critical. Also if anyone has recommendations for resources on these openings please let me know (books courses etc.)
