6. Be3 against the Najdorf Sicilian is called the English Attack.
[FEN "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1"]
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be3
6. Be3 is no weak move! It is a strong move and has been played by World Champions like Kasparov, Kramnik and Anand.
In your game, after 6...e5 you played 7. Nf5. ...
This is a good question, and I'd like to provide you an in-depth analysis but I don't have time right now, so here's a short answer, more to be added later:
Short answer: An immediate b5, before preparing it with e6, allows maneuvers such as Bd5 to be played, and you noticed correctly that here Bxf7+ is not really a threat.
Black should preferably avoid ...
The move a3 serves basically two functions:
White can develop the bishop to c4, and keep it aimed on d5, even if Black attacks it with b5, or, as Giri did, with Be6. In the lines where Black plays ...e5, the battle for d5 is often very important so it could be worth spending a tempo in it.
Black often plays b5 to gain some space on the queenside. The move ...
I ran this through Stockfish at 15 minutes per move. What I have found is that the sacrifice is sound and wins. But for a 'won' game, it is about the hardest road I have ever seen. The evaluation of the position is less than a pawn advantage for White up through move 25 or so.
The sacrifice leads to opportunities for White, but both sides are walking the ...
e5 is bad against the Fischer-sozin variation, because of 7. Nf5, which puts pressure on the d6 weakness.
Now granted, you could play Nf5 whenever black plays e5, whether you're playing Be2 (the classical system), or Be3 (the english attack).
So the real question is, what's the difference between:
e5 in the Sozin variation, and
e5 in the classical ...
This line is not very popular because black can challenge the bishop with 7…h6.
Now white is forced to exchange his bishop against the knight, either by taking right away 8.Bxf6 or after 8.Be3 Ng4. This is something you'd rather avoid, though its not immediately problematic for white.
If you try to avoid this with 8.Bh4 you run into 8…Nxe4. I actually lost ...
Let's forget for a moment that it's a Najdorf.
You were cramped because you never gave yourself space. Instead, you spent a lot of time wandering around with your knight and bishop and opening lines against your own king. You didn't develop. You didn't counter-attack.
When White castled on the opposite side to you, they were making a simple declaration: I ...
Yes, in the Sicilian black often falls behind in development, and that is a problem -- white often gets the chance to mount an attack.
But black has some compensation. After ...cxd4 Nxd4 he has two central pawns while white only has the e-pawn. In order to attack quickly, white often castles queenside and black can use the half-open c-file to start a ...
Pawn b7 generally wants to threaten knight on c3 at some point so definitely there is one piece that is interested in b4 square. But a3 is not developing move in open position so the deepest idea of this system is probably its surprise value.
One of the main themes in the Najdorf is: White attacks on the King side and Black attacks on the Queen side. You never started you attack on the Queens side.
Here is an example of Kasparov game with successful Queen side attack.

One reason is that it avoids a certain line that you would get after playing 7...Qb6, which is 8.Nb3
If Black plays 7...h6 first, 8.Bh4 Qb6 9.Nb3 is no longer possible because Black can play 9...Qe3+ winning the f4-pawn. This would not have been the case in the 7...Qb6 line since the bishop would have still been on g5, protecting the pawn.
Another reason ...
Sorry for the lack of a board here, I will learn how to paste boards here soon.
8.f4 b4 9.Na4 (Nce2 is reasonable too) Nxe4, one might ask, what has white got?
O-O and black has serious issues developing as the amazing line given by the comp (I wouldnt have seen this line) :
10...Be7 11. f5 e5 12.Bxf7+! Kxf7 13.Ne6 Kg8 ( Qd7 14.Qg4 wins material back, ...
I think that a lot of the answers to your various questions about "why this or that" come down to the fact that it is just very unexplored theory, and the black players are just using their best judgment, probably mostly on-the-fly since Rg1 is so rare. I have just 18 games in my database after 9...Bxe4, and 7 of those games were played by white players ...
I just adore the Najdorf. So I cannot help favoring it over the Scheveningen. Yes, these two variations differ. They differ because white uses a bit different attacking strategies. The great thing about the Najdorf is that there are excellent ways of counter-attacking. Black does choose between e7-e6 and e7-e5 in the different lines. For example, here is a ...
12. ...Bxh4. The flood gate of h file is opened in opposite side castling.
Knight on b8 is not activated.
Unclear plan of ...Ne8
...e5 looks weak as Bishop on c4 becomes very active.
...Re8 again looks week.
... hxg6 looks weak as the h file becomes open.
... h6 could have closed the file and cramped the position which becomes difficult for ...
I play the Najdorf with Black and would say that on move six White has tried almost everything: almost every legal move is a move and so are attempts like 6.h4, 6.a4 or the like.
That said, there are nevertheless basic principles and ideas that make some lines more sound (and played) than others. Historically the sharpest try to refute the Najdorf has been ...
My first thought is that "10...Ne8: I was trying to launch a Kingside attack myself, and get my knight to a better square eventually," is the key mistake. White has just castled Queenside and is very much in a better position on the Kingside (nevermind that you just had to reduce the activity of one of your pieces before you even began). Encouraging activity ...
According to the Game Database of ChessTempo, 7....Qb6 is actually more popular than 7....h6.
At the very top level, both moves have their supporters, e.g. Anand and Grischuk for 7....Qb6 and Vachier-Lagrave and Nepomniachtchi for 7....h6.
Both moves can easily transpose, as the main line of the Poisoned Pawn goes 7....Qb6 8.Qd2 Qxb2 9.Rb1 Qa3 10.e5 h6 11....
does it mean that Be3 is the best 6th move in the Najdorf for white
and does it mean that normal play with 6... e5 is very dangerous for
"No" is the answer to the first question and "Not really but in any case, as hoacin points out, there are plenty of reasonable alternatives for black" is the answer to the second question.
Look, whether it is ...
6...Ng4 doesn't look good at all.
Black is behind in development, so White should aim for direct play with 7.Bg5 and then:
7...f6 8.Bc1 [8.Bh4] Be6 9.h3 Nh6 10.Bxh6 gh6 11.Nh4 [11.Be2] and Black has huge weaknesses on the light squares.
7...Be7 8.Bxe7 Qxe7 9.Nd5 [9.Qd2, 9.Bc4] Qd8 10.Bc4 with a nice bind is probably the lesser evil for ...
Two or three games is very little to say much. You will not even have encountered all of the main lines after ....a6. Generally the Najdorf Sicilian is rather tactical and opening mistakes can quickly lead to a loss. In some lines white has a very straightforward plan of pushing its h and g pawns and checkmating black.
Practising tactics and studying the ...
This is not a gaping hole in opening theory. Looking through my reference database, White has an excellent score after 10.Re1.
Black needs to reply with 10...d5 not to be clearly worse, because of the weakness on e6(White can just crash through if Black is careless). After this there aren't many games, but White's score after 11.c4 is 73.3% in 15 games. The ...
Let's look at the position after
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e5
The downside of e7-e5 is that black loses control over the d5 square (e7-e6 is no longer possible). The upside is that black gets a strong control over the e5 and d4-squares. There are lines where black plays e7-e5 and follows up with h7-h6 to stop the ...
After Bg5 in the najdorf variation playing e5 would leave black with huge problems in the d5 square, white is ready to take on f6 with his bishop and ocuppy the d5 outpost with a knight or even take advantage of f7 weak spot by playing Bc4
With this particular continuation
should provide white with good play, I've compared some databases which generally favor white in this position. Instead of B5 many players including grandmasters favor an immediate 7...Qb6.
I suggest looking into some databases(chessgames.com has a fair amount of games as does chess.com ...
First, in chess, being behind in development is not always the end of the world. It certainly can be if your king gets stuck in the center of the board, and comes under attack; but there are many openings where one side can afford to fall behind in development to gain certain static advantages if the position is super solid. Then, you can catch up in ...
Well it all "depends" on the position, but in the given example, Nc6 is a better option as it has a possible outpost on d4 or b4 and with the rook on c8 it will also be doubly defended. It can even be re-routed to f6 if required which would be almost impossible from d7. Nbd7 does block the defense of the d6 pawn. BTW , I saw a study somewhere ...
