Which is sharper? Najdorf or Sveshnikov?

I played the Sicilian Dragon exclusively for many years. Now I am moving to either the Najdorf or Sveshnikov. Which is sharper? Which is more solid? I know both have tons of theory, especially the Najdorf. Which are 1.e4 players most prepared for? I welcome any opinions about their strengths or weaknesses.

I would say the Sveshnikov is more solid but the Najdorf is sharper.

My attempt at it:

Lol, that is the funnest game I’ve seen in a long time. Awesome. If I’d played it, I’d have the scoresheet printed and framed on the wall above my theoretical fireplace!

Thanks for the kind remarks.

You can probably see why I labeled it "A Heroic Defense".

The Paulsen can quickly turn into a sharp game. In fact, some lf my most memorable games have been with the Paulsen, where the board is ripe for the plucking... to the player that can find the fastest line.

In particular, when white castles queenside, it's fireworks after that. I've had both my most memorable wins and most memorable losses in those variations of the Paulsen.

Castling queenside, in the Paulsen with white sets up a monstous attack by white, trying to punch through the "d" file. But find counterplay, and white will be finding it hard to deal with.

i'd go with ginsu or obsidian.

My CAT likes running around the house holding a knife in her mouth. My freakin' CAT!

Now that's hard-core.

I think the Sveshnikov is a lot sharper. There are calm ways to play the Najdorf, not the Sveshnikov. 

You'll get blown to pieces in the Sveshnikov unless you know at least the first 12 moves or so and ideas. The whole point of the Sveshnikov is an incredibly audacious anti-positional opening, sort of like the Traxler of the Sicilians though better for black. 

I’m fine with learning openings to move 12, as long as the opening is sound and full of resources.

well, they do have nine lives.

Najdorf is more likely to face a kingside attack, right?

No pictures of my cat, but here's one of equal value:

What do cats think about the Najdorf and Sveshnikov? Mine doesn’t care either way.

Cats seem to prefer open games, rather than semi-open positions like the Sicilian.

I see Chessable has a new course by Chessexplained on the Sveshnikov. His work is always excellent.

That actually happened to me in the Dragon. I started running into players 400-500 points below me who had the entire Yugoslav attack memorized. It was horrific.

I think The Najdorf would be good. It actually depends on your level, but in my opinion the Najdorf is better. Try to avoid the Poisoned Pawn Variation. (I don’t like it) But make sure that your rating is 1500+!

My rating is about 1750. The more I look at the Sveshnikov, the less I want to play it, lol. I’m leaning toward the Najdorf, and at my level usually white players are out of book by move 8. The only thing that makes me hesitate is that the Najdorf is so common. I’d really like to play something my opponents don’t play against every other game.

6. Bc4 can be extremely sharp, such as the game I posted in post #2 of this thread.

Not true at all.    

The sting of 6. Bc4 was taken out of it by Fischer himself over quarter of a century ago.
