This is my favorite opening as well.

Thank you for your comments which are appreciated. This is my first annotation which I did to help my opponent better understand the game

It's also my favorite defense but for the wrong reason. As this is the first defense that my teacher made me learn. Nowadays, I don't teach it to my students unless they annotated a game that had Sicilian due to how difficult it is to learn with the amount of theory it contains.

Yes lots of theory...but still the best chances for a win as black. All the tactics in the Sicilian mean it is a great way to learn how tactical and positional elements interact in a game of chess. I love this opening. But I agree there is an insurmountable mountain of theory. But that is all part of the fun and the challenge.

Yes, when I play the Defense, I play the Sicilian Nadjorf as that's the line that Jack taught me. I had success with it, and despite how hard it is I don't change as for me it's, "stick with what you know" as per elyhim's and GM Susan Polgar's advice.

....and learn from what you don't know  

All familiar to me. Now, it's about what becomes of this since Jack stopped after telling me that this is all standard and implied that it's all I need to know about the Sicilian. Of course, I know he's not right about everything including this. So, I like your notes about white's 6th move.

You are right. This is just where the battle begins. You could devote your life to what follows from here. Most of us do not have the time for that. But that is part of the fun...always something new to learn.

Also playable are 5...Nc6, 5...e6 and even 5... e5!? Each shapes the game in different ways. Before I switched to the French Defence, back in my OTB days, the Najdorf was my favourite, too.

Critical. This is so significant as not only did Susan Polgar mention it, but I have a friend who's a Senior Master. And, by Senior, I think it means earning an IM title as a Senior but could be wrong about it. Anyway, he saccs the Q early on f7 and wins in his blitz Q sacs. So, if he's white, he'll start off with 1.e4 e5 2.Qh5 Nf6 3.Qxf7+ Kxf7 and despite being a Q for P down, he wins. The reason being is because his opponents aren't aware of how exposed their K is. So, feeling like they're going to win no matter, they underestimate by not developing properly, and with Joe's pieces well developed, he exploits that f7 weakness as is usually able to checkmate. Or he wins back the Q, and then some, until the position is resignable for his opponents. In fact, this is how I remembered what to do when my opponent when my opponent plays the Domiano's Defense, 4.Qh5+ after 1.e4 e5 2.Nf3 f6?! 3.Nxe5 fxe5?? And, I used that to teach some of my students chess.

owww....that might work in blitz. But if Black keeps a cool head he should win easily.

I know of this dude jkarp mentions through Gameknot. They are blitz games, generally against weaker opposition. However, this Bishop move was considered pretty bad about 120 years ago, but received something of a revival during Bobby Fischer's heyday, possibly due to his own influence. It's a very aggressive line, though not one that I favoured with the White pieces. Instead, 6.Bg5 used to be very popular (and successful) but I gather that in recent decades 6.Be3 has superseded it. The 'positional' 6.Be2 is also very playable for White.

That's interesting.

Now, one of the motivations of 5...a6, the signature move of the Najdorf, is that it prepares a central strike by 6...e5. Moves like 6.Bc4 and Bg5 cut across this plan, especially the former. It would be dangerous now to play 6...e5 with the bishop and knight controlling d5, whilst the d6-pawn is left backward and weak. The latter is a risk Black is willing to take, but he doesn't want to compound it by ceding too much control in the centre! So you will find that apart from the relatively rare 6...b5, Black almost always plays this more modest e-pawn advance.

Well explained.

Thank you.

As would I.

I saw examples of this in some of charleshiggie's annotations. And, I've learned a lot from his annotated games.

I hope you learn from mine too  

Threat: 10.e5, attacking knight and rook. It is not a bad idea insofar as one can to load each move with a threat. Even easily parried, short-ranged threats can be a means to an end.

Doesn't this ignore the 10.e5 threat though? Let's see: 10.e5 Bb7! This counter-attack saves knight and rook, both: 11.exd6 Bxd6 12.Qh3 Nc6 and Black emerges rather better off than White.

More often played is 10.Qg3, eyeing, perhaps, the g7-pawn, but also establishing a pin against d6.

10.Te1!? GM Golubev 10...Cbd7 11.Qg3 b4!? see mokio (2156) - remajik (2598) gameknot 1/2-1/2
