What do you mean give you concrete lines? There are no concrete lines because Black isn't in trouble. What you're asking for is like asking for lines showing black is ok against the grob or ok against the yugoslav attack. A stupid request. If you think you have something then you can easily find the answer to it by searching a database, a book or maybe computer analysis. Don't ask other people to do work for your imaginary attacks unless you pay them.   

Besides, there are all kinds of different ways to play and positional setups for the Scheveningen including against the Kere's, it's not like black has to play some super accurate narrow line - though of course he has to play accurately at times. It's not the sort of opening that there are many concrete lines for. Of course black has to play precisely at times which is why it's considered a dangerous opening.  

I notice you play the dragon yourself, which is played at a similar frequency to the Scheveningen at super gm level, and the results it does get at that level are abysmal, even Carlsen struggled to get results from it.  

How about you try to put lines where the Kere's supposedly has an incredible attack, you're the one trying to overturn the whole of opening theory. You're asking me to post lines to imaginary attacks here.

Completely false, it's the exact opposite. The Kere's Attack is an initially sharp opening with great chances to attack for both sides. If played accurately at the higher levels it tends to turn into a positional opening, black is not on the defensive in any way.    

PawnTsunami I can see by your attitude and the way you are producing a torrent of difficult claims at a time that you are looking for an argument and just going to use everything at your disposal to try to support your point, not trying to remain unbiased.

In short, you have the 3 most respected 1. e4 repertoires against the Sicilian all recommending the Keres Attack, and all concluding a strong edge for White.

Is this meant to be a joke?

Nothing any of them said there goes against anything I said whatsoever. I would also recommend the Kere's Attack against black. All they did is confirm exactly what I've been saying. 

This is getting really getting out of hand at this point. I made a simple and obvious observation of a well known and obvious fact. If you still don't understand that's your problem. Please don't argue with me again because you'll just be wrong.

lol - you could say the same thing about the d3 Ruy Lopez or many other highly critical openings. Your argument might be valid here if we were arguing is the Scheveningen the most theoretically critical opening. What YOU are trying to argue is that black is at some kind of inherent disadvantage which is false, especially under the GM level. The other way of putting your statement is that the Scheveningen is used as the literal main weapon of a few GMs and routinely by lots of others up to the very elite in the world. 

That means it's a really GOOD. Black is not "on the defensive", black is not at a disadvantage other than the usual. Maybe a "surprise lite", noone is going to be that shocked to see a regularly played opening. 

And yes - part of the reason it can be a good idea is due to its rarity. Chess has a kind of natural ecology and balance where the rarer openings can survive on any level despite not being the absolute mainlines. If everyone had to play the Najdorf and Scheveningen the same amount sure, the Najdorf would probably have a little better results. That goes for every opening, it's an inherent part of chess. Only complete amateurs try to memorize the most main line to every opening, that is too predictable, the only good player that ever used to do that was Weaver Adams and it was mostly just his gimmick. That doesn't make it a "surprise opening", just one of the lesser used ones.

See the statistics from my previous post to see why.  Additionally, it is not only played FAR less than the Najdorf, it is the least played mainline in the Sicilian at the IM/GM levels.  Does that mean it is unplayable?  Of course not.  However, the reason it is not anyone's main weapon is due to the Keres Attack.  If everyone knew you were going to play the Scheveningen, they would prepare the Keres Attack against you every single game, and Black's results are very bad in that line.

Man, I don't like how you've put your statistics because you look like you're trying to bias them to making the Scheveningen look bad. I don't know why you can't just lay them out clearly. Why not just give a screenshot of your database. 

Your numbers show that the Scheveningen is played almost as much as the Dragon, not that it's "far less". I was honestly surprised that the dragon is getting more play than the scheveningen, but saying it's by far more played than it is just plain wrong. 83 vs 129.

White doesn't even play the Kere's attack literally half the time which blows your other dogmatic claims that black's going to suffer badly from it away. Also you didn't give any statistics for when white didn't play the Kere's attack.   

The statistics you posted against the Kere's are very healthy for black.

The King's Gambit is not refuted; rather, it has basically been worked out to a draw.  In other words, if it were your main weapon, Black would simply need to knock out ~35 moves of theory and shake hands.

That's basically what refuted means - a draw.

I could have sworn you had "Caro-Kann" in there before I clicked quote, but just in case:

The Caro-Kann was played 2414 times in 2019 at the IM/GM levels.  White won 33.1%, drew 42.2%, and lost 24.8%.  It is played quite often at that level.  It has not been in fashion at the World Championship level recently, but that is due to fashion, not so much results.

The Pirc was played 650 times in 2019 at the IM/GM levels (with very similar results:  White won 35.3%, drew 37.5%, lost 27.2%).

The Pirc was played more than 6x the amount of the Scheveningen last year.  The Caro-Kann more than 25x. 

I did have Caro-Kann but edited it as on second thought I thought the Caro might have more. Those are interesting statistics for the amount played, I don't put much stock in the results since there are any number of reasons why the results might be better or worse for a particular opening, for example someone might play some openings against players rated better than them and some against people rated worse. Of course the Scheveningen is a move 5 move while those are move 2 moves, but fair enough that they're played a lot more.

While I agree that lines can go in and out of fashion, the main reason masters do not play the Scheveningen against other masters very often is to avoid getting into a sharp theoretical battle with the Keres Attack (where White's attack is straight-forward and easy to play while Black's defense rests on the edge of a razor blade!)

White's attack is not easy to play at all - why do you think half of the players decided against the Kere's attack in the statistics you posted? 

White gets a very unusual and complicated position quite quickly, where there is no easy way progress can be made. This is completely unlike the Yugoslav attack where white has several modes of attacking straightaway. You can't just assume it must be like other sharp openings. 

Once again I appreciate the effort and agree when you say that the Kere's is a major reason why the Scheveningen is played a lot more. But when you say stuff like black is on the defensive or in a bad position it is obvious you have NO IDEA what you're talking about. Trust me dude, I have looked at the Kere's attack a LOT, I am not out here just talking about things I don't know about. I've gone through all the variations and all the positions. The Kere's attack is played positionally at high level, it's not a sharp opening at high levels.

PawnTsunami wrote:

While the Pirc and Caro-Kann have "tiny theoretical" edges for White, the Keres Attack is more than just a "tiny" advantage. 

What?! I am not talking about the substantial advantage white has when I said tiny theoretical edge, I am talking about the tiny advantage of the Najdorf over the Scheveningen.

If you look at it with engines, you see Lc0 evaluating the position after 6. g4 at +0.75-1.00 (strong edge for White!), and SF 11 evaluates it at anywhere from +0.50-0.70 depending on the depth you let it go to (again, strong edge for White).  Granted, those are engine lines, but if you look deeper into it, you'll see that on every move, White has 2-3 good options and Black only has 1 option - and this goes on for the next 8-10 moves.  This is why players tend to avoid it:  practically, it favors White.

Hahahahaha. Now I can see you're just clearly making **** up. 

As I said I have gone through this. If you had went through the opening with a computer you would notice black has a ton of different plausible moves every step of the way. a6, d5, e5, Qa5, Qb6 and so on. You are literally thinking oh it must be like the Yugoslav Attack or KID or King's Gambit when it's not. 

As meaningless as it is to compare computer evaluations with an opening, the Kere's Attack is literally 0.0 or thereabout when you go through it with a computer. Play through any of those lines longer than just 6. g4, there is no computer that is going to evaluate a Kere's Attack line as being good long-term for white because it's just equality.

You cannot seriously be suggesting that the Pirc and Caro Kan have better computer evaluations when just looking at them they have +0.6 to +1.0 evaluations all over the place. Don't talk ****.

His post was a bit hyperbolic, but not at all foolish.  If you want to play the Scheveningen structure, the better way to do it is to go into it via the Najdorf move order.  Which is what Kasparov did for all but 2 games in his career.

Oh man.... this just goes to show how unreliable and confabulating you are. Kasparov played the Scheveningen all the time before his match with Karpov. I thought you might be thinking of that he only played it twice in his match with Karpov but then I found he played several more of them in that match as well. 

https://www.chessgames.com/perl/chess.pl?page=1&pid=15940&playercomp=black&eco=B80-B85&title=Garry%20Kasparov%20playing%20the%20Sicilian%20Scheveningen%20as%20Black

These results include the Najdorf move order so you have to click on them to check if he is using the Scheveningen - in the early games he plays generally use the Scheveningen move order. Also you can see "Kere's attack" listed after some of them (even though he played other ones without the kere's attack, about half of white wouldn't use it according to your statistics), and he still played it 1996, 1998, 1999, 2002... so this is Kasparov, the man notorious for giving up the Scheveningen and still using it.  

That other guy's post was also as I said it was. I am really disappointed at myself how I got sucked into wasting a lot of time going through this bs nonsense today, don't expect me to come back again.

So...A lot of words, some good points, but yet one problem...you are still refusing (albeit cleverly) to show me actual moves that Black can play against the Keres to reach a good position. Ok, I’ll start if u won’t. After 6. g4, Black has 5 moves: the dubious 6...e5 and the also dubious 6...Nc6 which both lead to bad positions for the second player. 6...a6 is better than them but still fails to hold back the g-pawn and leads to a nice edge for White, and that is if Black plays extremely precisely to avoid losing outright early. 6....Be7 will simply transpose to either the Nc6 or a6 lines, which are not so good for Black. Finally, we have to address Black’s only decent move 6...h6, restraining the pawn. White should press on with h4 provided they want to play a true Keres (h3 leading to a good h3 Najdorf for White is also good) Now Black can play a6, Be7, e5, or Nc6, the main line. The first two simply allow Qf3 followed by g5, leading to at a minimum an edge for White. e5 is better but still allows White to get an edge with Nf5. The final move Nc6 is the main move. White normally plays Rg1, threatening g5, forcing Black to take immediate action. Negi gives three moves for Black: Nd7, h5, and d5, the main move. The first two allow White to gain a fairly large advantage, much like the advantage White gets if Black allows g5 without doing anything (ex:a6). d5 is Black’s best, leading to two types of positions. The first kind are crazy attacking positions, but ones where White retains better chances. The second are queenless endings, but ones where White presses due to their better pieces and pawn structure. If you aren’t convinced, I can give more lines upon request, or you could get Negi’s book and try to refute it. Also, if you want me to give concrete lines that show me the Dragon is fine, I can and will, which is what I think you should do when debating an opening.

chrisbarcacook
Let’s bring this back to the main point of my post. I am trying to learn the Scheveningen but preferably through the Najdorf move order with 5...a6 and 6...e6. My questions are what are the typical plans associated with the opening? Also when White plays something like Be3, is it preferred to just play 6...e5, or can black also play 6...e6 and be equal?

Black isn't in trouble?  Funny how almost half the games played in the line were wins for White at the IM/GM level.  At the very least, it is far more practical to play White than it is Black from the starting point.

Black is virtually winning on move 2 against the Grob, and has some difficulties against the Yugoslav Attack.  These are also well known.

This is simply complete nonsense.  The road for White from the starting point of the pure Scheveningen is rather wide; the road for Black is very narrow.  You can see that by looking at the databases, or looking at how the engines evaluate it.

Apparently you do not understand.  The claim that the Scheveningen has trouble because of the Keres Attack is known theory.  It does not have to be "the most theoretically critical opening" to justify that claim.  Just like the Yugoslav Attack is known to give the Dragon the most problems.  In both cases, Black is forced into a defensive posture for quite a while.  You can try to claim otherwise, but you would just be showing your lack of knowledge on the subject.  I would suggest picking up Negi's 4-volume 1. e4 repertoire (3 of which are dedicated to Sicilian lines), Shaw's 3-volume 1. e4 repertoire (1.5 of which are dedicated to the Sicilian, and where he completely dismisses the pure Scheveningen because of its problems), and de la Villa/Hollingworth's book on facing the Sicilian lines.

The fact that you can get away with an opening at the class level does not make it theoretically sound.  I know class A players who play the Grob as their main weapon.  That doesn't make it a good opening.

The other way of putting your statement is that the Scheveningen is used as the literal main weapon of a few GMs and routinely by lots of others up to the very elite in the world. 

That means it's a really GOOD. Black is not "on the defensive", black is not at a disadvantage other than the usual. Maybe a "surprise lite", noone is going to be that shocked to see a regularly played opening. 

That is literally the exact opposite of what I said, and of what the database would show you.

Man, I don't like how you've put your statistics because you look like you're trying to bias them to making the Scheveningen look bad. I don't know why you can't just lay them out clearly. Why not just give a screenshot of your database. 

Your numbers show that the Scheveningen is played almost as much as the Dragon, not that it's "far less". I was honestly surprised that the dragon is getting more play than the scheveningen, but saying it's by far more played than it is just plain wrong. 83 vs 129.

White doesn't even play the Kere's attack literally half the time which blows your other dogmatic claims that black's going to suffer badly from it away. Also you didn't give any statistics for when white didn't play the Kere's attack.   

The statistics you posted against the Kere's are very healthy for black. 

I didn't skew them.  I just listed what was played last year at the IM/GM levels and the results.  It isn't meant to make anything look bad, it was meant to give you some perspective.  The Scheveningen is not the main weapon used by any IM/GM.  

If you look at the games where White did not play the Keres Attack, Black fairs MUCH better:

1-0:  35.9%

1/2-1/2: 35.9%

0-1:  28.2%

And comparing it to the Dragon (which is the 2nd lowest played Sicilian mainline at the IM/GM level - due to a similar problem) is silly.  You are literally saying "OMG, see!  It is only slightly in last place!"

Just because not every White player knows, or wants to play for an all out attack, does not change the theoretical evaluation.  I showed the statistics to demonstrate that it clearly has a practical, if not theoretical advantage.

And no, losing almost 50% of the time is not a healthy line for Black.

That's basically what refuted means - a draw.  

Then Chess is refuted since with best play, the result is a draw.

That is, of course, not accurate.  Refuted means "prove to be wrong".  The King's Gambit is not refuted, but it has been analyzed out so far out that the result with best play is a draw.  The same goes for lines like the Smith-Morra Gambit.  GMs would play that as a surprise weapon to catch their opponent outside something that is fresh in their mind.

I did have Caro-Kann but edited it as on second thought I thought the Caro might have more. Those are interesting statistics for the amount played, I don't put much stock in the results since there are any number of reasons why the results might be better or worse for a particular opening, for example someone might play some openings against players rated better than them and some against people rated worse. Of course the Scheveningen is a move 5 move while those are move 2 moves, but fair enough that they're played a lot more. 

The database I use is a filtered version of the Mega Database (where no players below 2300 are included).  This means the games are only from ~1968, and only players at the FM/IM/GM level.  These games are not between weak players.  The pure Scheveningen is played MUCH more at the sub-master level, where Black has much better results.  Those games are not theoretically important because of the number of blunders from both sides.

Uhohspaghettio1 wrote:

What?! I am not talking about the substantial advantage white has when I said tiny theoretical edge, I am talking about the tiny advantage of the Najdorf over the Scheveningen.  

This shows you do not understand why Kasparov preferred the Najdorf move order to get into the Scheveningen:  5..a6 forces White to do something useful (usually develop a bishop) since g4 is not possible (it would just hang the pawn).  This forces White to choose a plan.  If they still want to go for the g4-push, it would be the English Attack, which while sharp, is a bit slower than the Keres Attack (giving Black better chances to defend).

Uhohspaghettio1 wrote:

White's attack is not easy to play at all - why do you think half of the players decided against the Kere's attack in the statistics you posted? 

White gets a very unusual and complicated position quite quickly, where there is no easy way progress can be made. This is completely unlike the Yugoslav attack where white has several modes of attacking straightaway. You can't just assume it must be like other sharp openings. 

Once again I appreciate the effort and agree when you say that the Kere's is a major reason why the Scheveningen is played a lot more. But when you say stuff like black is on the defensive or in a bad position it is obvious you have NO IDEA what you're talking about. Trust me dude, I have looked at the Kere's attack a LOT, I am not out here just talking about things I don't know about. I've gone through all the variations and all the positions. The Kere's attack is played positionally at high level, it's not a sharp opening at high levels.

Not everyone wants to go into a theoretical (i.e. memorization) battle.  It is why some White players choose the Karpov Variation against the Najdorf instead of the English Attack or Ritcher-Rauzer.

The last paragraph above is simply nonsense.

Uhohspaghettio1 wrote:

Hahahahaha. Now I can see you're just clearly making **** up. 

As I said I have gone through this. If you had went through the opening with a computer you would notice black has a ton of different plausible moves every step of the way. a6, d5, e5, Qa5, Qb6 and so on. You are literally thinking oh it must be like the Yugoslav Attack or KID or King's Gambit when it's not. 

As meaningless as it is to compare computer evaluations with an opening, the Kere's Attack is literally 0.0 or thereabout when you go through it with a computer. Play through any of those lines longer than just 6. g4, there is no computer that is going to evaluate a Kere's Attack line as being good long-term for white because it's just equality.

You cannot seriously be suggesting that the Pirc and Caro Kan have better computer evaluations when just looking at them they have +0.6 to +1.0 evaluations all over the place. Don't talk ****. 

Yep, I, and every theorist in the last 10 years (and I'm not even among them BTW) have just "made [stuff] up" and you, in your infinite wisdom are smart enough to see through it.

Seriously though, try actually doing the research.  The top moves played after 6. g4:  h6, a6, Nc6, e5, Be7, d5, Nfd7, g6.

h6 is the only move that doesn't give White a very strong edge (which is why it is by far the most popular reply).  After h6, White has 6 replies that all leave him with a strong edge.  3 of them will transpose after a few moves, but there are move order tricks Black has to avoid with each one.  And then Black has to resign himself to the fact that his king is likely going to be in the center the whole game (because castling long would be suicide and castling short would be castling into the attack).

And yes, anyone who is familiar with the English Attack will find the Keres Attack straight-forward.  Black's position is very difficult to play, which is why the results are so skewed at the highest levels.

Oh man.... this just goes to show how unreliable and confabulating you are. Kasparov played the Scheveningen all the time before his match with Karpov. I thought you might be thinking of that he only played it twice in his match with Karpov but then I found he played several more of them in that match as well. 

https://www.chessgames.com/perl/chess.pl?page=1&pid=15940&playercomp=black&eco=B80-B85&title=Garry%20Kasparov%20playing%20the%20Sicilian%20Scheveningen%20as%20Black

These results include the Najdorf move order so you have to click on them to check if he is using the Scheveningen - in the early games he plays generally use the Scheveningen move order. Also you can see "Kere's attack" listed after some of them (even though he played other ones without the kere's attack, about half of white wouldn't use it according to your statistics), and he still played it 1996, 1998, 1999, 2002... so this is Kasparov, the man notorious for giving up the Scheveningen and still using it.  

That other guy's post was also as I said it was. I am really disappointed at myself how I got sucked into wasting a lot of time going through this bs nonsense today, don't expect me to come back again. 

You really REALLY should look at the games before you try to make the claim.  If you look at the games, you will see that in all but 2, he goes into the Scheveningen from a Najdorf move order (i.e. 5..a6 6..e6).  You need to do more research.  Have a good day.

Let’s bring this back to the main point of my post. I am trying to learn the Scheveningen but preferably through the Najdorf move order with 5...a6 and 6...e6. My questions are what are the typical plans associated with the opening? Also when White plays something like Be3, is it preferred to just play 6...e5, or can black also play 6...e6 and be equal?

There are a lot of typical plans from the starting position after 5..a6 and 6..e6.  The main idea is that you want to develop quickly and prepare to push either e5 or d5 to break open the game (once your pieces are ready for it).

You can play 6..e5 or 6..e6 with perfectly fine games.  I've played both, as did Kasparov and Fischer.  Note that against some of White's 6th moves (e.g. Bc4, Bg5), you should not play 6..e5.  6..e6 is one good option in both cases.  Nfd7 can often be a good alternative to delay the decision about what to do with the e-pawn for a move or two.  There is an older Everyman book:  "Play the Najdorf Scheveningen-Style" that you may want to look at.  Keep in mind that some of the lines may not hold up to modern engine analysis, but the plans will largely be the same.  Also note that when you play the Najdorf this way, you often will end up in a Hedgehog-like setup, so it will be useful to understand that structure.  Sergey Shipov has 2 books on that structure that are well worth studying.  And if you decide you want to play the Najdorf proper (that is, with 6..e5 when possible), the book "Opening Repertoire:  The Sicilian Najdorf" that was released last year is very good.

As @FizzyBand and I have mentioned a couple times, you may also want to check out White's ideas.  The Negi, Shaw, and de la Villa/Illingworth books are all excellent.

For black, it is when you have a6, b6, d6, and e6 played.  Sometimes you might see g6 with Bg7 as well.

So...A lot of words, some good points, but yet one problem...you are still refusing (albeit cleverly) to show me actual moves that Black can play against the Keres to reach a good position. Ok, I’ll start if u won’t. After 6. g4, Black has 5 moves: the dubious 6...e5 and the also dubious 6...Nc6 which both lead to bad positions for the second player. 6...a6 is better than them but still fails to hold back the g-pawn and leads to a nice edge for White, and that is if Black plays extremely precisely to avoid losing outright early. 6....Be7 will simply transpose to either the Nc6 or a6 lines, which are not so good for Black. 

This is totally false, not only are there more "decent moves" (the term you use later) than 6. ...h6, every one of those moves are fundamentally playable for black even at high levels. This is what I was trying to explain when you asked for concrete lines, PawnTsunami as well who assumed black would be walking a tight-rope from the start like the Najdorf poison pawn or something - the Scheveningen doesn't work like that most of the time, it is a really flexible opening. Yes you have to play accurately against some variations of the Keres, if you play into them. 

You dismiss 6... e5 and 6. ...Nc6 out of hand as being "dubious" yet 6. ...e5 is the first choice of stockfish at depth 40 so while I don't trust the analysis of computers but clearly it's at least playable. It gives an evaluation of 0.7 at depth 40 which is typical of sharp openings (eg mainline benoni is 0.5 to 1.2 sometimes). According to lichess database 6. ...Nc6 is the second most played move after 6. ...h6 and is played more than one fifth of the time by master players so it can't be that bad, especially below the highest levels.

At lower levels once you prepared really well you could concoct all manner of tricks and traps with several of these openings. 

6. ...h6 only decent move - not by any stretch of the imagination.   

FizzyBand wrote:

Finally, we have to address Black’s only decent move 6...h6, restraining the pawn. White should press on with h4 provided they want to play a true Keres (h3 leading to a good h3 Najdorf for White is also good) Now Black can play a6, Be7, e5, or Nc6, the main line. The first two simply allow Qf3 followed by g5, leading to at a minimum an edge for White. e5 is better but still allows White to get an edge with Nf5. The final move Nc6 is the main move. 

All of those moves are again completely playable. 

FizzyBand wrote:

White normally plays Rg1, threatening g5, forcing Black to take immediate action. Negi gives three moves for Black: Nd7, h5, and d5, the main move. The first two allow White to gain a fairly large advantage, 

8. ...h5 was the main line for years. White may well be out of book already at the lower levels. Like most of the moves in this opening, it's actually white if anything that is walking a tightrope. Several times when you look through a database, if white choose the wrong move it's black who has the better win rate. Black has be careful, but it's his opening and he should know it all. For anything other than the highest levels of chess 8. ....h5 should work fine.  

FizzyBand wrote:

White gets if Black allows g5 without doing anything (ex:a6). d5 is Black’s best, leading to two types of positions. The first kind are crazy attacking positions, but ones where White retains better chances. The second are queenless endings, but ones where White presses due to their better pieces and pawn structure. If you aren’t convinced, I can give more lines upon request, or you could get Negi’s book and try to refute it. Also, if you want me to give concrete lines that show me the Dragon is fine, I can and will, which is what I think you should do when debating an opening.

Refute it? You expect me to refute the Kere's attack? You may as well ask to refute the Ruy Lopez. There is no refutation of a serious opening loike the Kere's attack. 

All you've shown is that white has better chances if he can play super accurately, this is how every opening works, especially aggressive counterattacking ones like the Scheveningen.

Black isn't in trouble?  Funny how almost half the games played in the line were wins for White at the IM/GM level.  At the very least, it is far more practical to play White than it is Black from the starting point.

I don't know what the hell are you talking about. According to lichess which is from strong master games (2350+ rating) since the 1950s the Scheveningen has the best scoring results of any of the main Sicilians other than the Classical: 

You're obviously looking at an anomaly, probably you're not choosing enough games. I already told you you can go screw your statistics that you're just fishing out of god knows where with the intention of choosing the ones to support your argument.  If you think I'm going to play this circle jerk game you're dreaming.

"Just because not every White player knows, or wants to play for an all out attack, does not change the theoretical evaluation.  I showed the statistics to demonstrate that it clearly has a practical, if not theoretical advantage."

lol, don't want to play for an all-out attack? You can't just dismiss all those games because they didn't play it. Clearly they didn't believe they could handle it. 

Having almost twice the win rate as black if you're white is hardly that much of a deathknell at high GM level, especially if there's a high draw rate. The poisoned pawn variation of the najdorf is still generally considered highly critical and has 24% win for white vs 14% black - which I guess will count as your "hurrr almost twice as much". 

You have repeatedly shown you are unwilling and/or unable to look at the statistics unbiasedly.

As I CLEARLY explained, as I CLEARLY explained and even provided you with a link, SOME of those games DID NOT start with the Scheveningen move order. MOST if not all of the early games did. I already went through them, as I clearly explained.

I told you that. Why didn't you listen to what I said? Are you like actually an adult? I know chess kids post around here sometimes. Come on dude.   

Furthermore, at least 3 of Kasparov's games in the Kasparov - Karpov Championship of 1984 used the move order with 5. ....e6.

In the hedgehog Black wants to stay ultra-solid, giving nothing for White to easily attack. If Black went b5, White could go a4 and weaken Black's queenside. In most Sicilians when Black plays b5 it is a more attacking position where a significant edge would not be gained through positional flank pawn play.

@Uhohspaghettio1 since what it is coming down to is that we don't agree on the theoretical evaluations of Scheveningen positions here's an idea. Let's play a daily game in the Scheveningen. We can both use all the books and resources (not engines of course ) we want.

The idea behind the Hedgehog setup is to create no weaknesses.  You will see some people describe it as a coiled spring because once you get your pieces where you want them, you can open up the position favorable with a very active middlegame.  The trade off is that you allow your opponent a space advantage in the meantime.

No thanks, I don't play daily and one game between disparately rated players isn't going to prove anything anyway.

Something to be clear about first is that we are talking about something that will transpose to a Najdorf at least half the time. It happens about half the time at GM level and a lot more on amateur level. The difference between the Scheveningen and the Najdorf is with the Najdorf white can play 6. Bg5 while with the Scheveningen white can play 6. g4 (Kere's). So you could use a Najdorf guide if you wish, just dismiss what they say about Bg5 - usually the longest and most complicated part of the defence. 6. Bg5 is still possible but white's normal plan is too slow - just remember Black should play Be7 (obviously) and an early h6, he also shouldn't play Nc6 too soon or he'll run into a Richter Rouzer mainline which white may well have prepared for.     

If there was one word to describe the Kere's I think it would be "messy". Don't worry as it's not too hard to learn it at all and once you know it I think you improve your understanding of chess.

Sometimes black castles kingside (only if he is very careful that he can though), sometimes he gets shelter behind doubled pawns, sometimes he castles queenside and sometimes he goes right in the middle. Instead of learning exponential amount of variations you're better off in looking at and understanding these positions. If white thinks he has some significant attacking advantage that is very dangerous for him, especially if he has little clue how to attack the position which is what you'll find at amateur level.     

Here's Karpov at his prime getting fried by a man named Hartmann: 

https://www.chessgames.com/perl/chessgame?gid=1068351

Here's the famous game Kasparov vs Karpov: 

https://www.chessgames.com/perl/chessgame?gid=1067129 

What the history books write is that Kasparov abandoned the Scheveningen as his main Sicilian after this match due to the Kere's attack. What they leave out however is that Karpov had already abandoned playing 1. e4 against Kasparov due to his sicilian performance in this match where he used the Scheveningen.

That is a question that would require well more than a forum post to answer.  So, instead of trying to give you a half-answer, I would redirect you to a few resources:

https://www.amazon.com/Play-Najdorf-Scheveningen-Style-Repertoire/dp/1857443233

This book is a bit dated (~2003), but Emms is a well-respected theoretician and at the club level, you are not likely to find someone who knows the refutations for the inaccuracies found by engines 10+ years after it was published.  Note that while several lines go into a Hedgehog setup, his objective was not to reach that whenever possible, so there are lines where Black plays a6 and b5 with ideas of counterplay on the queenside.

https://www.amazon.com/Complete-Hedgehog-1-Sergey-Shipov/dp/0979148219

https://www.amazon.com/Complete-Hedgehog-Vol-2/dp/1936277220

These books give you detailed examples of various plans from different forms of the Hedgehog (not just ones you can reach from the Sicilian - there are many openings that can allow you to reach this setup).  The chapters are organized by the plan employed.

Some recent example games from the Sicilian move orders (though not necessarily Najdorf or Scheveningen starting points):

And one where Black fell apart fairly quickly:

And to demonstrate that you can get to it from a variety of different openings:

 

Of course, you also cannot go wrong with any of Kasparov's games in the setup.

Note that Kasparov also wrote the Foreward to both of Shipov's books.

king5minblitz119147

Playing e6 on move 5 allows g4 but it does allow Na6-c5 in some lines if white does not go for the keres attack. That is one benefit I can think of. On the other hand, 5..a6 is vastly more flexible and hides your intentions until you see white's.
