Oh, thanks. No, I play the mainline.
How to learn the Sicilian Najdorf as thoroughly as possible?

GM de Firmian said once Najdorf fans consider the variation the path to ultimate truth in chess, the opening to the perfect game, if that thing exist. But how could the perfect game start with 1. e4?? (just kidding). I think it could be a Semi-Slav, what also requires a huge amount of study. IMHO the proper study of such variations must be preceded by a vast experience.

I want to thoroughly learn the Najdorf. How should I go about doing this?
Links to any websites, videos, or online training tools would be appreciated.
If i were you, I would stick with opening principles for now.

I actually disagree with a lot of people. Slowly learning the theory of an opening like the najdorf CAN be very good.
What OP must realise if this is to work is that openings are long term projects. You should aim to slowly assimilate information about the opening over a couple of years, rather than mass working on it in one go.
I suggest after each one of your games entering the sicilian that you go to a database/book or both and see where you or your opponent deviated, and briefly try to understand the plans for both sides from the position that occured. This method takes only 5-10 minutes post game, improves your knowledge of theory, AND maks your knowledge of theory conform to the replies that are most played against you, rather than those that are most played at GM level.

Hi dear friend i don't recommend you any book about the Najdorf because authors are not entirely honest ... Here i wrote a little introduction about this great defense http://www.chess.com/blog/JRgascon/introduction-to-najdorf-sicilian ... You can learn it by yourself by watching Fischer's games or with somebody's help...

Thank you. This is very helpful!

Become one with the chess goddess. Other than locking yourself in a room with only a chess board for 20 hours a day -- this is the only way.

Everyman Chess has a good book that I used before...
Starting out: Sicilian Najdorf
Then start playing it, get that game analyzed by people who play the najdorf, compare with sample games (e.g. from chessgames.com)
That's it!

And how much of that is a self-fulfilling prophecy passed down by people like de Firmian? Amateurs running around learning Najdorf openings 28 moves deep because they heard it was a daring opening when a well-prepared 2. Nc3 would likely hurt them much more.
To learn the Najdorf as thoroughly as possible:
1. Become a grandmaster
2. Become a correspondence player
3. Study what others have written about the Najdorf
4. Come up with your own theories of the opening
5. Test those theories out in elite competition, and be prepared to refise them constantly.
Don't skip any of those steps.
Kasparov once said that nobody below GM level should play the Sicilian. He was overstating things a bit. But the Najdorf in particular is extremely difficult and should probably be left to the professionals (+2100 USCF).
This is an interesting thought. If you are below GM level you are likely playing losing moves in the Najdorf.
That said he also famously stated that any opening with a name is playable against even weak masters.
In my opinion below a certain level (say NM) white obtains a moster of an advantage just by playing the open sicilain with either the Bg5 line or the english attack. I feel that even most experts do not have the ability to defend whites monster attack.

Watch Sam Shankland's Najdorf series in chess.com he's a 2660 Fide GM and knows what he's talking about. I learned more from those videos than any silly videos on YouTube on the opening.

I just wrote a basic primer for learning the Najdorf. It focuses on the two most important things you should know first. The pawn structure and the "why" behind the first few moves and how to evaluate the position as you go so you can play based on a plan as opposed to just memorizing lines. Then as you go I would suggest you find some really good games by top Najdorf players and do the evaluation planning method for their moves.

@pilateblue so, how's it going with the Najdorf 16 months later?
All too predictably, I'm afraid - OP hasn't been active for over a year now.
The Najdorf Sicilian? Not a great choice for someone seeking to build an opening repertoire from scratch.

Do whatever you want. But someday you may end up wishing for your time back. I say you'd be much better off studying tactics and keeping the opening prep to a minimum.
who you think yourself to dictate who to learn what? as*****

Do you really need step 2?

To be honest, I really don't think an opening like the Najdorf is the best choice for a player of your rating level. You have to know an inordinate amount of theory, be booked up on all kinds of sidelines, and waste time studying 20+ moves of opening theory when really what you should be doing to get better is learning tactics and maybe some endgame stuff. And at under 1600 level, in my experience hardly anyone plays the Open Sicilian, and even if they do, they won't play the main lines of it, so all your hours of prep will be almost a complete waste of your time.
I agree the Najdorf is a little too much. I recently looked at the Sicilian and decided not to use the Najdorf, in part because of the large number of variations whose move order you need to follow carefully.
Instead, I chose the Safest Sicilian, the Taimanov (1 e4 c5 2 Nf3 e6) because the typical moves lead to the position after 3 d4 cxd4 4 Nxd4 Nc6 5 Nc3 Qc7 and even after the English Attack, 6 Be3, Black is solid and does not have to memorize a lot of variations and the move order is often not critical.
Another one that's safe for someone who doesn't want to memorize lots of variations, that I've been looking at, is the Siclian Kan. It's related to the Taimanov (1 e4 c5 2 Nf3 e6 3 d4 cxd4 4 Nxd4 a6)
Note that after Delchev and Semkov wrote the book The Safest Sicilian about the Taimanov, Georgiev and Kolev wrote a book in the same series, The Sharpest Sicilian about the Najdorf and this excerpt from the introduction gives you an idea of how complex it is:
Here's my last Sicilian Taimanov. Look at the two chess.com index pics below the board - the inaccuracies and mistakes did not result in bad positions - and the Lucas Chess/Stockfish 10/20 ply move analysis that follows them and you can see it wasn't hard for me to find good moves with the Taimanov:




@Pulpofeira
Fort Knox occurs after 1. e4 e6 2. d4 d5 3. Nd2/Nc3 dxe4 4. Nxe4 Bd7. Black's next move is Bc6 and he plans to get rid of the bad bishop for one of the knights and play it essentially like a Caro-Kann. It's fairly solid but not considered as good as the mainline Rubinstein because black has to surrender both the center and the bishop pair.
