How do you play the K.I.D. when White plays e3 instead of e4?

To answer your question about why lines without e3 or e4, those lines I mention DO feature e3 or e4.  I am making the specific point that if White plays 4.e3, which is rare compared to other lines FEATURING e3, LIKE 4.Nf3 O-O 5.Bg5 c5 6.e3.  The topic is on e3 in general, and he gave "4.e3" as an "Example", but the TOPIC is e3 instead of e4 as a whole, and I was pointing out that you will rarely see 4.e3 comparatively speaking to other lines that feature e3 instead of e4, SUCH AS 4.Nf3 and 5.Bg5.

 

If you don't understand the point, you never will and are clearly not advanced enough to speak chess at a 2000 level.

 

I understand your point perfectly well - "4. e3 isn't played as much by good players therefore must not be as good" - right? Not exactly the most rigorous chess analysis - you wouldn't even have to know how to play chess to make that sort of analysis. 

Just because something isn't played as much doesn't mean it leads to equality - what opening gets played is also a matter of taste, style, surprise-value and even fashion. There is chess fashion as much as there's hat fashion, good players aren't just machines who will always play objectively the best opening most frequently. Besides I'm not arguing that 4. e3 is objectively as good as 4. e4 or even 4. Nf3 or 4. Bg5 at all as I have already stated, I am arguing white is still significantly ahead and it is not equality at all. As the IM stated it's a dangerous system.     

I wasn't aware that playing chess on a 2000 level in chess involved treating what is most frequently played as the Ultimate Truth of what is good. Must be where I was going wrong this whole time!

The whole point is that if White commits too soon to e3, Black can take advantage of the fact that all lines are equal after 4.e3, whereas with delaying e3 (but note that e4 is also not played yet, so there is no ...Nxe4 trick - see original post), it is not as easy.  It's called educating the author of the original post why playing e3 TOO SOON can be bad for White.  If Black is fully equal by move 4, that is BAD for White in my book.  White goes first - he should have a slight advantage over Black!

This is just restating your claim again. You're not adding or showing anything, you're just restating your claim that e3 too early is bad because he commits to it. Saying the whole point is that he can't commit to e3 too early is not showing anything. What if I kept repeating THE WHOLE POINT the d3 ruy lopez is bad because white commits to d3 too early? That's not proving anything, just restating my claim.

As far as your final paragraph, yes, delaying e4 leaves the LIGHT Squared Bishop open, but what about the DARK Squared one?  He's going to have to move e4 eventually and it becomes a wasted move for White.

We already went over this. First of all saying "it will have to go to e4 eventually becomes wasted move" is stupid. Do you know the Meran Semi-Slav, one of the most famous and frequent and lengthy openings in the whole of chess? White plays e3 then usually a later e4. I can promise you it is not a wasted move. Really I don't know how you got this idea. 

And secondly, the dark-squared bishop can easily be justified on b2. There are mainlines with these moves, in several ways it's ideal here, here it may be particularly useful after d5 has been played and to oppose the g7 bishop. Meanwhile I don't know what miracles you think it's doing on the kingside, especially when the e7 pawn is still in place there's no pin against the queen or anything similar.

This all the more explains WHY White should play 4.Nf3 and either 5.Bg5 or 5.Bf4 BEFORE playing e3, and if he doesn't do that, Black has easy equality!  With the Dark squared Bishop outside the pawn chain, before e3 is played, there may never be a need for e3-e4 by White, and often the e3-pawn ends up on d4 after a trade of pawns by Black!

You basically should have answered your own question with your response why 4.e3 is inferior to getting the Bishop out first before playing e3, such as 4.Nf3 O-O 5.Bg5, INTENDING 6.e3, and here 5...c5 is the way to go, where the only way White can get a slight advantage is to go the Benoni route.  If he is insistent on e3, then 6.e3 cxd4 7.exd4 d5 is equal.

 

Wow, you really want him outside the chain don't you? I'm not sure what miracles you think white's dark-squared bishop is performing on f4 or g5, particularly against the fianchetto. As you know moving the queen's bishop to that side of the board leaves one open to Qb6 and similar attacks on the queenside and b2 pawn in many different openings. Black's early movement of that bishop is also not ideal. 1. d4 d5 2. c4 Bf5?! what do we move as white? Nc3 followed by cxd5 and then Qb3 or something similar is the most accurate response, hitting that pawn and exposing the clumsily placed bishop. The queen's bishop is very difficult to deploy in an aggressive manner without leaving weaknesses behind for both sides in queen pawn openings. White's best option in the orthodox queen's gambit is to swap for black's dark-squared bishop straightaway - when white is trading off a bishop that early in the game without any attack it is clearly not an amazing attacking piece. 

I think you are getting things confused with black needing to get his light-squared bishop out which can indeed be very important. However it's different for black as he can get cramped a lot. White has much more control and a pawn on d5 that cannot be removed (or if it is will be replaced by cxd5). When have you ever seen a game when white quickly got mated getting cramped in the opening and a useless bishop? It would almost never happen without while with black it's quite possible.    

Bg5 against the queen's gambit declined or semi-slav, while not obviously and indisputably the best move, has the merit that e6 has been played so the knight is under pressure and there's a pin on the queen, here there's nothing like that, the bishop is almost useless. In addition to that he has a bishop on g7 that is attacking the b2 pawn that your dark-squared bishop was defending and now is not.

Nonsense. See this is where you're getting into trouble and proven wrong - when you say "equal". They are not equal. Just look at the position ThrillerFan - white has a pawn on d5 and good control of the centre. A pawn on d5 that cannot be cleared! He has no weaknesses (unlike in the mainlines). I really think may be time to go back to the very basics if you think this position is equal.

And as far as the Bishop holding the b2 pawn - if that is what you are doing with the Bishop, you are basically telling your a1-Rook that he will never see the light of day as he will be blocked for ever by the Bishop!

Right, well this is the only reason why moving the c1 bishop isn't a completely stupid move. It does help develop, especially the rook.  

ThrillerFan wrote:

So while some of your arguments, like having e4 available for the Knight, might be legitimate, they give White no advantage if you don't get that Dark-Squared Bishop out from behind the pawn chain first!

Why, so he can be locked on the kingside of the board instead with no hope of doing anything the whole game? I mean one of the whole points of Bg5 is that you could move it back to f4, e3 or d2 after h6, or alternatively you could move Qd2 and Bh6 forcing the exchange of bishops - your bad and useless one for his good one. 

ThrillerFan wrote:

So long story short, if White goes for e3-lines:

A) If e3 is played on move 4, White has nothing.  4...O-O and 5...c5 in the majority of cases (i.e. obviously not if 5.c5, but that move is stupid and Black is better in other ways) and Black is fully equal already.  Not winning - simply equal, which is fully satisfactory for Black on move 5!

B) If White gets the Bishop out first, maintaining flexibility with the e-pawn, which may still go to e3, then again, Black should not play for ...e5, but rather, once again, ...c5, and White gets a tiny edge if he goes into the Benoni lines, and merely an equal position if he plays 6.e3, though Black in this case must act accordingly, playing 6...cxd4 and 7...d5, not going for the stereotyped move ...d6, claiming "But I am a King's Indian player".

C) If Black looks to force the issue with ...e5, playing moves like ...Re8, then White is usually better in the e3-lines.  Black should not take this route if White goes for e3.

Again with this "equality" nonsense.

Really bro, many openings are like this in their main lines. A huge part of your chess education is clearly lacking, you are embarrassing yourself. 4. e3 is a good move and a viable chance for getting ahead. 

I also recommend LOOKING AT THE ACTUAL BOARD. You're bringing in all these arguments like "good players play this with a lot more frequency so it must be better" or "e3-e4 must be a waste of time because you use up an extra move instead of just e4", and bizarre pronouncements of "equality" in totally normal positions where white clearly holds onto the opening advantage.

Your "assumptions" are assinine and moronic!

I have NEVER said that popularity equates to soundness.  If I did, I would say exactly that, that more occurrences means better theoretically.  Why do you think I specifically explained that the issue with 4.e3 is the dark-squared bishop, and if you hold it back, the Rook on a1 suffers?  Why do you think I specifically explain the concepts like the loss of tempo compared to other lines?  DUH!  Moron!

 

And you question about the Bishop doing nothing outside the pawn chain.  If it is useless, trade it off!  Which would you rather?  A useless minor piece and a useless look and Black has all 8 of his pieces? (Pawns are not "Pieces"), or have a second useful Rook, and get rid of your useless piece, and remove one of Black's knights?  The latter sure sounds better than the former.  Obviously specifics matter as to whether to trade off the Bishop for a Knight or not.  There is no "generalization".

 

Also, your hogwash about a White advantage.  I guess that's why Black scores near (9...Re8) or above (9...Na6 or 9...Bg4) 50% against your proposed line.

https://www.365chess.com/opening.php?m=18&n=167515&ms=d4.Nf6.c4.g6.Nc3.Bg7.e3.O-O.Nf3.c5.d5.d6.Be2.e6.O-O.exd5.cxd5&ns=7.14.11.15.17.17.5370.7886.963.520.16989.11452.15850.171521.150504.172706.167515

 

Where you got the absolutely moronic idea that my claim is popularity equates to level of soundness is dumber than anything I've heard come out of Trump's mouth, and Trump is the one of the dumbest people alive on the planet!

And by the way, I do look at an actual board.  Board and 32 pieces, not some stupid 2-D thing on a stupid computer screen, like chess.com!  Best way to study is on a real board like what you use to play OTB tournaments!

 

I should also add that in those 277 games on chess365.com, Black scores over 65% (and over 56% of his total games are wins!)

 

A valid sample size is 30, so whether Black scores over 65% across 277 games or over 65% across 5,000 games doesn't matter.  It's still a 65+ percent score across a valid sample size.

 

Try again!

Uhohspaghettio1

That's the "big database". White's advantage in the big database is marginal because lower-rated players are not good at making use of the advantage. 

In reality White has a healthy score 32% vs 25% from the lichess database where only over 2200 rated FIDE players' OTB games are included:  

Also a valid sample size is not 30 because the samples aren't independent of each other. It's the same players playing each other a lot of the time. 

Note the sample games also - Grischuk and Caruana are really going to play a dumb noob move that hands equality to the opponent right? 

Just leave it. 4. e3 retains the white advantage and is a good move. You were completely wrong, this is like pulling teeth trying to argue with you. Some of what you said was slightly interesting and I enjoyed some of the discussion. But you're not going to suddenly be right by whipping up a whole new post full of rhetoric, stop.

30? Relevant sample size? LOL

@pfren, sometimes I play Old Indian Defence. There's one strong opponent who annoys me with 1.d4 Nf6 2.c4 d6 3.Nc3 Nbd7 4.Nf3 e5 5.e3 and quick queenside expansion afterwards - exactly the plan You are talking about. Now would You rather play 5...Be7 or 5...g6? I've tried both, and it seems that Black gets slightly more counterplay with 5...g6 (though I admit that queenside threats are scary).

And you clowns that think I am wrong simply because I am an expert and pfren is an IM?  What if I told you that the equality assessments come from a GM, not me?  I simply posted them!  The 4.Nf3 O-O 5.Bg5 c5! Was not my intervention.  It is from a 10 hour GM video.  That change your tune?  If so, then who is the idiot now, using rating to determine validity?

Being an expert does not mean you know less than an IM in all areas.  Just means you are less well rounded, probably can't always find all the best candidate moves, and may not calculate as deep, and likely know fewer openings well.

I have far more holes in my game than pfren (Grunfeld theory, Dragon theory, Candidate moves, Same color Bishop endings, etc), but that does not automatically mean that one cannot be stronger in an isolated area, like French Theory, in my case, but weaker across the spectrum!

 

Shaquille O'Neal was a great basketball player, better than any high school kid, but the kid might actually be better at free throws!  He also could have learned the right way to shoot free throws via private lessons from Michael Jordan and not have gotten the ideas himself!

Even when 10 people say the same thing, as long as one of them is a titled player people will rush to complement the titled player on how wise and good they are, even if their post was the least accurate of all 10.

Having said that, @thrillerfan, while knowledgeable you're also known for being contentious and argumentative.

Argumentative is not a bad thing.  You need to be very good at argumentative writing in many fields.  Politics, law, management (arguments about policy changes at schools, universities, corporations, etc), and many other fields!

As far as being contentious, also not a bad thing.  Sometimes arguments need to be stirred up.  It is often how the truth eventually gets pushed out.  Without an argument, the truth often gets covered up, similar to how everything in America has been one big fat coverup since the 2016 Election!

 

The thing about being argumentative is you have to know when to push and when to sit back.  If you look back, you might see a post or two by me per thread, explaining things at the 10,000 foot level, when it comes to subjects like the Grunfeld, Dragon, or Leningrad Dutch, but you will have a hard time finding me trying to push a point across on that topic.  Argumentative writing requires knowledge in what you are arguing!

@pfren, isn't 1.d4 Nf6 2.c4 g6 3.Nf3 Bg7 4.e3 0-0 5.Be2 d6 6.Nc3 Nbd7 intending ...e5 quite playable for Black?

 

Of course it's playable... aren't all Black's moves legal?

But this is not a very practical way to meet this system, as white's queenside initiative is very fast, due to the extra tempo, compared to the French KIA.

I see. Interestingly 6...Nbd7 seems to be by far the most common move here (but doesn't score very well).

Edit: I got confused there. Actually Black scores 60% after 6...Nbd7 in ~2400 games with an avg Black Elo of ~2000 (according to Chessbase Mobile). I know that this doesn't mean that it's a good move, but at least it means that at lower levels it works in practice.

Was not my intervention.  It is from a 10 hour GM video.  That change your tune?  If so, then who is the idiot now, using rating to determine validity?

Being an expert does not mean you know less than an IM in all areas.  Just means you are less well rounded, probably can't always find all the best candidate moves, and may not calculate as deep, and likely know fewer openings well.

I have far more holes in my game than pfren (Grunfeld theory, Dragon theory, Candidate moves, Same color Bishop endings, etc), but that does not automatically mean that one cannot be stronger in an isolated area, like French Theory, in my case, but weaker across the spectrum!

 

Shaquille O'Neal was a great basketball player, better than any high school kid, but the kid might actually be better at free throws!  He also could have learned the right way to shoot free throws via private lessons from Michael Jordan and not have gotten the ideas himself!

 

 

And to the clown who wrote post # 66

 

You kept on pushing me to explain myself and have.  You haven't explained jack to validate your claims!  You just sound like a broken record basing validity on the rating of the people you hear it from and maybe one or two games played by a GM must make it so great for the side the GM played.  You have nothing!  If you think your statements hold any water - PROVE IT!

Your minor is in math? LMAO, my MAJOR is in math.

 

Clearly you never took Statistics (or else slept through that class) if you don't even know what the definition of a valid sample size is!

And yes, it is 30.  The number comes from mathematical models and has to do with level of significance (alpha level), variance (sigma-squared), standard deviation (sigma) and confidence intervals.

Obviously statistics based on population is different than statistics based on a sample size, but if your sample size is below 30, it's too small, and the variance is too high to deem the statistics as being valid.

 

If you take 5 people that have corona virus, and 3 of them are Hispanic, the variance is way too high to validly claim that 60 percent of Corona Virus victims are Hispanic.

 

If you take 30 people that have Corona Virus, and 9 of them are Black, the variance is right at the point where one could validly say that roughly 30 percent of Corona Virus victims are Black.  That doesn't mean it wouldn't be better to have a larger sample size, and of course the larger sample size would lower the variance and standard deviation, but this is the minimum that can be used to make a valid statistical point.

 

If you take 600 people that have Corona Virus, and 180 of them are White, the variance is significantly lower than that of the 9 out of 30 are Black, and so the variance (the plus or minus) will be smaller relative to the number of people.  The confidence interval will also be wider in this case.  You might have a 98% confidence interval here, and only a 90% in the 9 out of 30 example (Percentages are hypothetical to make a point, not actually calculated).

ROFLMAO!  You are studying it!  I've had my degree in Computer Science with the minor in Math for over 20 years ya clown!  No wonder you don't know anything!

You implied you're a college student. I assume you're not.

You might be a math genius, that's fine with me, but my impression of you is you're young. Just sayin'

Computer science? LOL, that's pretty much an inferior math major and non-relevant when discussing computer science, talk about an appeal to authority boomer.

Are you suuuuuuuuuuure I'm not in college? You talk like someone who isn't able to properly wage the age of someone by his writing.
