Thanks -- I guessed it might be since the pages on 7 ..Nbd7 seems to total forty-odd judging by reviews. Should be some meat there!

Would that book be the best source of reasonably up-to-date info (apart from ChessPublishing of course!) on the non-Dembo lines?

I notice that that Kg2 move (after 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O 6. Be2 e5 7. O-O Nbd7 8. Be3 Re8 9. d5 Nh5 10. g3 Bf8 11. Ne1 Ng7 12. Nd3 Be7 13. Qd2 f5 14. f3 Nf6) was given as leading to a slight advantage for White in Panczyk & Ilczuk's 2009 book (citing a game in which Black replied 15...fe 16. fe Ng4).

True, and I like the Classical line against the Fianchetto too.

Hi JEH and thanks. Yes, these are very much my perspectives too even tho' I've never actually tried the Dembo line. I like McNab's ideas and that's why I was attracted to the rather strange-looking ...b6 line, where in some circumstances I imagine Black can even play on the queenside but where the battle could really flare up anywhere depending on both players' aggressive or pacific intentions! Strategic yes, but Golubev (I think it was him) makes the point in one of his ChessPub game annotations that the ...Nbd7 lines can get surprisingly rich and lively! Of course, if Black goes ...exd4 things could get very strategically and/or tactically sharp as a matter of course and here I guess a close knowledge of Classical Fianchetto lines would prove very useful ...

I've been playing the Nbd7 KID for many years. Actuallty not studied a lot of theory for it. Possibly atypical of a KID mindset, I play it for a more slower battle. I like the uber solid way Colin McNab plays it (and the Pirc), so I would look there.

I've played the dangerous Re8 weapon version in one game, and got destroyed, so yes, it's dangerous. The line in the other thread with the prophylactic Qd2/f3/Kg2 plan does seem to kill black's play. I wouldn't like to go there.

Rather than Re8, I'd prefer a set up with c6, to meet d5 with c5 to slow down the queenside play, and/or Qe7 with a plan of exd4. These aren't going to set the board on fire, but that's how I like to play it (or maybe I'm just getting old  Wink), and it's not exactly hotly theoretical, but solid and strategic.

If this is the case, motorhead, what is your recommendation against the lines given by Ametanoitos and Daniel on the other thread? -- are you suggesting (a) that Black is really fine there (and if so, how?) or (b) that Black should choose a line other than the ...Re8 one (and if so, which)?

Black's plan has been refined in recent years with one or two tries involving ...a5 and even ...c5. Anyone know what's 'hot'?

I'm also interested in 7 0-0 Nbd7 8 Be3 Qe7 9 Qc2 c6 10 Rad1 b6!?, which might be 'a bit better for White' formally speaking but which has worked for Kozul and McNab! Tricky stuff?



As just said, 7... Nbd7 works fine against 8.Be3 but nothing has changed with 8.Qc2. So this was and is the critical variation.

I agree with Markovich. I own both of her Everyman books as well and fine them to be quite good. Her assessments are sometimes vague, for instance "Black has the initiative" or "I'd prefer Black", but that's fine for me in a repertoire book. I think it should be up to the reader to take further steps and investigate all of her critical positions anyway.


First of all, we now discuss two books which aren't relevant for the very topic. Back to that I still find it not too helpfull what Dembo shows us. She presents a dangerous weapon but misses to explain how to use it. As said in a post before, she gives some variations with comments like "black is fine". But what about the function of that weapon? I think that is not to the point, that series of books has.
I do not possess other Dembo-books but I have Watson's "Dangerous Weapons The French". Compairing these both books for me leads to a clear result: Watson is much more insightful (but that too is off the topic Wink)
What I can extract from the ractions in this thread up to now is that the dangerous weapon 8.Qc2 Nh5!? isn't really dangerous at all, nor is it doubleedged enough for Black to muddy the waters. I simply see no active way to proceed after 9.Bg5 f6 10.Be3 Nf4 11.Bxf4 exf4 and now say 12.a3 (or pass)...

I think this is the understatement of the year!
I have the feeling that every opening Dembo writes on seems to win by force!  Grin

I have her book on the Gruenfeld and a friend of mine once told me that in her view "with perfect play white can reach a worse endgame which he might be able to hold with very precise play".  Wink

Actually I find this lack of objectivity a bit annoying, if you trust her as a player you are bound to be disappointed. It is always necessary to question the assessments.
At least an objective coverage might point the reader to variations that are a problem or could become a problem in the future, but her books are written with rose-tinted spectacles.
With a little objectivity they would be much better!


I don't agree that Dembo's work is seriously marred by lack of objectivity.  I have both her Gruenfeld and her Beating the Anti King's Indians.  In each case she's writing a repertoire book, and her case is for the Black side.  Most of her judgments are pretty sound, it seems to me.  She often enough spins it for Black when White could well argue differently, but that's about the most that could be said against her.  It's not as if she routinely serves up bad positions and calls them good.

Nobody should trust any chess book, particularly a repertoire book, but that's no criticism of Dembo.

8...c6 is the old main move; the aforementioned Poles appear to think it is better than 8...Nh5.  By "the very main line" I would think PatzerNoster means 8. Be3 c6 9. d5 c5 10. Ne1.

Only after a careful examination you should do so!

For example I don't see how black should get satisfactory play in the absolute main line of Nbd7 after a white Ne1.


Thanx, I agree off course. But: Sorry. give me hints. I'm not lazy at all, but how can I deal with 8.Qc2 ff. ? Is 8....Nh5 really an idea or is it a flaw? Would 8...c6 be better? What do you think? Sorry, I cannot deal with your Nbd7, Ne1-quotation... There isn't a moveorder at all.
As I remember it, 8...c6 leads to a somewhat passive position. But, as I feel, 8... Nh5 is extraordinarary, but no better. Now what? 
Any hints? 
Thx, cheese

Dembo is right - most of the time but you must use your own brain too- no opening book can be 100% right.

You might want to look at Van Wely's play for white in the main anti Be3 line. Mcshane has tried nbd7 a few times with reasonable results .


Hmm. May well be, that Dembo is right most of the time. And, don't be surprised, I am willing to use my brain too. That was the very reason for my question here.

In the exact variation 8.Qc2 Nh5!? 9.Bg5 f6 10.Be3 Nf4 11.Bxf4 exf4 my feeling was that Dembo's verdict is too optimistic and overall that this section was worked out in a superficial and confused way. And that slightly reminded me on John Nunn's words in the chapter "Books on offbeat openings" in "Secrets of Practical Chess".

May be that there were no usefull games on the item. But then the author is obligued, to produce variations and indications on his/her own. That's what I pay for.

Up to now no one has given me hints that relieve me from my doubts. The reverse ist true.

That is true about every analysis.

Apart from "Dangerous Weapons: KID" I only have Dembo´s book "Fighting the anti-King´s Indians" which seems decent and objective enough to me.

Playing g6-g5 doesn´t mean to follow with g5-g4 immediately. Instead Black may play Re8 an Nf8-g6 first.


I wasn´t able to find Lalic´s game cited by Kylemeister. I agree that White is slightly better here but instead of 13...Qe7 in this case more critical looks 13...a5 14.a3 f5 intending 15.exf5 Rxf5 16.c5 d5.

Overall Dembo is probably a bit too optimistic about Black´s chances here.

Cheesemate, perhaps you should look into the lines after 8.Qc2 c6. White is surely slightly better here too but Black´s game is more solid than after 8...Nh5.

P&I cite 12. Rad1 c6 13. b4 Qe7 14. c5 (from a game of Bogdan Lalic's) as leading to a slight advantage for White, and they think the same should apply to 13. Bd3.

What about following the game Ikonnikov-Kornev, Russian Championship 2000? There Black refrained from f6-f5 and instead choose a setup with g6-g5 and Qe7.


I'm not really convinced about that. What is Black heading for? I can't see it. A pawnroller on the king's side? May be, but after g5-g4 there may follow Nf3-h4, direction f5. If White is carefull I think Black achives nothing. Despite the pawn formation f6-g5-f4 and d6 sheds no light on black's king's bishop.
As I saw Ikonnikov played b2-b4 in that game offering the opportunity to lever with a7-a5.
The question to me is how black can do something active. If he sits waiting, white will build up on the e-file.

Over all the comments, Dembo gives to that exact variation in the DW book are incoherent to may feeling. She gives some moves in four subvariations after 11...exf4 but no plans. And she judges black to be fine in positions where some further explanation would have been helpfull. In one game there followed 12.b4?! (in my view) 12...a5 13.a3 f5 14.exf5 Rxf5 "seizing the initiative". Well, may be, but what if white doesn't compromises with 12.b4 but plays say 12.Bd3 or even 12.a3...
which way should black go? 

@ kylemeister: What is the main variation your quoted authors give to 9.Bg5 etc.? Would be nice if you give some moves.

Thx

I haven't tried to do any real thinking about this, but I noticed that the Panczyk/Ilczuk book from last year thought highly of White's chances after 8. Qc2 Nh5, in all kinds of lines (including 9. Bg5).

Inspired largely by the success of Radjabov and Bologan I recently decided to add this still relatively underrated but interesting line to my Black repertoire. An opportunity soon arose for me to give it a practical test in a Rapid tournament where the following position was quickly reached: 

Fide Master vs Toppy - Rapid Tourney (E94) 12/04/09

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.0-0 Nbd7 8.Be3 Re8 9.d5 Nh5 10.g3 Bf8 11.Nd2 Ng7 12.b4 f5 13.Nb3 Be7

Incidentally and unbeknownst to both players at the time the above position was briefly outlined by Yelena Dembo in Dangerous Weapons: The KID, quite a useful book by the way, particularly if one is willing to put in the extra analytical work required. Here Dembo writes "Black prepares …Bg5 and later f4; it is clear that Black’s kingside play is well underway."


The mainline, TopNotch referred to, seems to be quite right in regard of Black's classical attacking patterns as this thread shows.

I'm more concerned  with the simple 8.Qc2. Dembo has an overview on that, but I'm not really convinced (as in total her articles in the DW KI are a bit thin, to my feeling. In the main line she has not streched to far beyond that what Watson said on this special variation in "Mastering the Chess Openings vol. 2").

On 8.Qc2 she gives 8...Nh5 (otherwise White may follow up with Rd1 and Black has to pay attention not to drift into a passive position; e.g. 8...c6 9.Rd1 Qe7which is difficult after say 10.d5) but it is not easy to find something fluid against 9.Bg5 f6 10.Be3. Black's pieces are now a bit misplaced to my feeling.

Yes, with 10...Nf4 11.Bxf4 exf4 Black can snatch the pair of bishops. But what ist the price? White dominates in the center, while Black does not really has suitable levers. Yes, there is f7-f5, but this opens the position (exf5 Txf5) giving White posibilities on the e-file (X e6). The natural set-up will be Bd3, Rfe1 and Ne4 or Re2/Rae1 or both to come.

I have my doubts  that Black is able to create an attack, because the pieces stumble over another. 
Rybka sees White a clear bit better (up to +0,60 or 0,70).

Any ideas?

Another issue in this variation is 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.Be3 Nbd7 8.d5!? which Dembo skips in her coverage but Golubev assesses as better for white.

Strangely enough in a recent game Dembo herself allows this possibility, although in the Dangerous Weapon book she states this is a position that Black would do better to avoid.

One thing is for certain, those who play the Classical with White have a helluva lot of prep to do these days as Na6, Nbd7 and Nc6 all seem to be brimming with Life and going through a rival. Long gone are the days when you mentioned the word KID that someone would remark "Didn't Kramnik refute that".

The blurb to Semkov's new book Kill the KID sums up how I think many White players feel about the Classical variation in general: 

Semkov: I have always been unhappy with the Classical variation against the KID It’s an enormous amount of theory that is impractical to keep in pace with, even for a professional player. An ever bigger problem is the character of positions that arise. There is something basically wrong to give Black players such attacking chances as in the Classical variation.

I sure hope that the majority of Classical players don't share Semkov's sentiments. Wink

That's true, but many strong players play it after 7.Be3, so she could have given some information there.

Dembo reccomends sidestepping the Gligoric with the move order 6...Nbd7. Also her articles are after 7.O-O and not after 7.Be3

Wow, 14...f4! is such a natural move (especially for the King's Indian) that I can hardly believe I didn't even consider it (although I'm sure Toppy did consider it but probably mistakenly rejected it).  I know I was too fixated on the idea of swapping dark-squared bishops with ...Bg5.  14...f4 looks like a very satisfactory answer to 14.c5.

I played yesterday a nice game with Black against the "Tarzan Attack" and won in style and there was my old coach watching the game and i felt nice when we analysed it together afterwards and received his compliments about my game improving etc....

Why i say all these? After the analysis of my game i showed him the position we are discussing here after 14.c5. My coach is one of the true "gurus" of the KID and i always show him interesting new trends in the openings because i trust his outstanding judgment and he can direct me to the right path.

So, when i played 14.c5 on the board, his 20 years experience in the opening almost immediately stoped me and he tried the sequence of moves 14...f4 15.gxf4 exf4 16.Bxf4 Bf6 17.Rc1 (i analysed protecting the knight with the queen with the help of my PC afterwards and the evaluation doesn't change) 17...Bxc3 18.Rxc3 Rxe4 and stoped here to think. After a minute or so he said: "Hmmm, it is not as easy as i thought at first. Maybe Black is not better after all, but he has a playable position for sure. I don't like 14.c5 for White. Maybe 14.Rc1 first?"

I was amazed by his reaction! I was analysing this position from the first day i saw it here and i never considered this transformation. This has to do mainly because i analyse with the PC i think. I immediately went from being proud that my understanding of the KID was good to felting very little indeed! 

I don't know if 14...f4 leeds to a better, equal or slightly worse position for Black after all, but i know that we should try harder to work on our understanding of typical positions and trasformaations. My coach saw this without blinking and we, so many minds here, didn't!  Embarrassed

GM Golubev just posted his review of the DW - KID book at http://www.chesspublishing.com/content/9/biblio.htm, and has promised to look at these lines in his April update! Wink

And don't fall into this:  http://www.chesspub.com/cgi-bin/yabb2/YaBB.pl?num=1234807911

(although from what I know of your repertoire it seems unlikely to be a concern) ...

Lots of interesting replies here, and I will need some time to work through all these suggestions before posting any analysis. Unfortuantely this analysis could be delayed a bit as currently I'm hard at work trying to whip myself into shape for a tournament starting the 27th April featuring GM Rainer Buhmann GM Alex Shabalov GM Alonso Zapata plus a host of IM's and FM's. 

Hopefully when that tournament has concluded I will have some theoretically interesting games to report, particularly as it is unlikely that these games will be captured by conventional database sources such as TWIC and the like.

Wish me luck, I'm gunna need it.

A couple of thoughts after 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.0-0 Nbd7 8.Be3 Re8 9.d5 Nh5 10.g3 Bf8 11.Nd2 Ng7 12.b4

1) Is there a reason Black can't vary his move order and play 12...Be7!? and meet 13.Nb3 with 13...Bg5.  After 14.Bxg5 Qxg5 15.Nb5, Black has to play 15...Qd8 but now ...a6 will gain a tempo on the knight and Black can get some play with ...f5.

2) After 12...f5 13.Nb3 Be7 14.c5 a6!? (Ametanoitos), doesn't White get a nice edge with 15.c6?

I know that this may sound stupid but i tried to play the position after 14.c5 against my PC and i played 14...a6 with the idea to prepare Bg5 without allowing the Nb5 move. Ati first i thought that it should lose somehow but my computer failed to strike the final blow and quickly i got chances against the White king. I analysed the position after that and i honestly believe that it is unclear somehow!

I think that Rowson in chess for Zebras wrote that modern GMs don't bother if a move looks dubious in the hypertheoretical sense but they care only if it works. Maybe 14...a6 works! Analysing with the PC, the engines give 3 or 4 moves with the evaluation "clearly better for White" but after ...Bg5 and two or three moves after that they realise that Black has decent chances for an attack. So....that's the problem with the KID always!

Why not simply 18...Rb8? What can White do with the additional tempo in this position?  I will follow up with your plan anyway.

eg:
18. ... Rb8 19.cxd6 cxd6 20.Bxa7 Ng4 21.Bxg4 Bxg4 22.Qd2 Rc8 23.Nxb7 Qd7

Must I reconsiderate my prejudices against 8...Re8 ? I always have thought that Black has huge problems to involve that rook in his attack, based on a remark by Euwe. Isn't Blacks attack considerably slowed down compared to 7...Nc6 8.d5 Ne7 and 7...Nbd7 8.d5 ?
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

Inspired largely by the success of Radjabov and Bologan I recently decided to add this still relatively underrated but interesting line to my Black repertoire. An opportunity soon arose for me to give it a practical test in a Rapid tournament where the following position was quickly reached: 

Fide Master vs Toppy - Rapid Tourney (E94) 12/04/09

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.0-0 Nbd7 8.Be3 Re8 9.d5 Nh5 10.g3 Bf8 11.Nd2 Ng7 12.b4 f5 13.Nb3 Be7

Incidentally and unbeknownst to both players at the time the above position was briefly outlined by Yelena Dembo in Dangerous Weapons: The KID, quite a useful book by the way, particularly if one is willing to put in the extra analytical work required. Here Dembo writes "Black prepares …Bg5 and later f4; it is clear that Black’s kingside play is well underway." This assessment may well be true, however after my opponent’s natural reply …Bg5 ideas become problematic. Moreover it should be noted that the position after 13…Be7 does not seem to have received any practical tests in tournament play so far, which only serves as further testament to the fertility of this 7…Nbd7 line.  

14.c5 Nf6 [14…Bg5 is well met by 15.Bxg5 Qxg5 16.Nb5 with a clear advantage to White]

15.f3 fxe4 16.fxe4 Bh3 17.Rf2 h5 [This felt quite typical and natural at the time and indeed after my opponent’s equally natural response Black’s initiative grows steadily. However this is not the end of the story as you will see] 

18.cxd6?! [Turns out that 18.Na5! would have been much more challenging than the text, after which it is quite possible that White is simply much better. The position still remains quite sharp and needs a thorough analysis but intuitively I remain skeptical of Black’s chances. Anyway, back to the game]     

18…cxd6 19.Na5 Ng4 20.Bxg4 Bxg4 21.Qf1 h4 22.Ne2 [Losing his nerve and switching to defensive mode, but in so doing the pendulum swings completely in Black’s favor. 22.Nb5 would have been more testing]

The rest is carnage 

22…Qd7 23.gxh4 Bh3 24.Qd1 Bxh4 25.Ng3 Rf8 26.Rc1 Nh5 27.Nxh5 gxh5 28.Qxh5?? Qg7+ 0-1

Despite Black’s success in this game some important questions remain to be answered, such as how to improve Black’s play should 18.Na5 prove good for White. 

Ideas welcome, and perhaps Dembo, Palliser and Flear could also share their thoughts.

Regards,

Toppy Smiley
