Kibitzer's Corner
Aug-09-03  Dustin J.: I like and play the White Opening & Black Defense. But countering the White openinging is easy playing Na6 and opening up the Queenside while holding onto your King Indian's Bishop. The kingside is rock solid for Black and the center soon becomes compromised for White. Thats my take on it anyway, heh.
Apr-04-04  Bears092: anyone know of good books on this (preferably from the white side)?
Jul-13-04  tomh72000: 7...a5! is usually preferable in this variation, I thought?
Jul-13-04  notyetagm: The great KID expert Joe Gallagher has a book due out in September 2004 titled <"Play The King's Indian">. From the Everyman Chess book publisher, it is supposed to be a repertoire book for Black in the KID. I am sure it will answer this question you have about 7 ... a5! in the Petrosian system. Personally I am curious what he will recommend against the dreaded Bayonet Attack (9 b4 and 10 Re1 in the Classical system).
Jul-14-04  tomh72000: Yes, the Bayonet made Kasparov give up the KID I think.
Jan-24-05  cuendillar: Not a book on it, but a video from on how to beat the King's Indian with the Petrosian system. Hope it can help out a little.
Oct-09-05  Dudley: There is large section on this opening for White in "Play 1.d4" by the English player Richard Palliser. This is packed with dense analysis and seems comprehensive. One of the games is the Kramnik-Bologan game covered in the link above, which unfortunately doesn't seem to work anymore.
Oct-09-05  Dudley: I feel sorry for your students.
Jul-27-06  soughzin: I don't understand why 7...a5 is the main move here. Is it just to prevent b4? What is black's plan to undermine white's imposing locked in center? All I can think of is c6 and f5 sometime. Can a KID guy(or gal) help me out here?
Jul-27-06  ganstaman: From my limited experience and understanding of the KID: black wants to expand and put all his pieces on the kingside, while white gets the center and queenside. Black definitely wants to move his N from f6, play f7-f5, and then probably put the knight back. He will then continue to pawn storm the kingside, supported from behind by his pieces.

I think c6 is too risky for black, since opening the queenside gives white a way in. Once white does open the queenside, his heavy artillery will make its way to the back few ranks, distracting the black pieces from their kingside attack. Then white is calling all the shots and wil win.

I'm pretty sure ...a5 is to prevent (or at least slow down) a b4 push from white. If white gets in b2-b4, his queenside presence is awe-inspiring, and perhaps winning. Therefore, black must take a few defensive measures before claiming the kingside. I've read somewhere (maybe here?) that the Bayonet Attack (which features b4 from white) gives black the most trouble in the KID. I haven't played it nearly enough to verify this, but it sounds like it could be true.

Jul-27-06  ganstaman: Hmmm, had I read a few posts above mine, I would have seen: <tomh72000: Yes, the Bayonet made Kasparov give up the KID I think.>
Jul-27-06  soughzin: I guess that makes sense but it still seems bad to fianchetto the bishop and then it gets so little scope. Maybe a design flaw you have to accept when the KID also brings imbalances and kingside chances?
Jul-28-06  Cecil Brown: <soughzin> I'm currently playing through Starting Out:The King's Indian by Joseph G Gallagher .

He gives this game (which I have just submited via the PGN upload utility) as a model game against the Petrosian system.

7...a5 is played to restrain b4 by white and therefore secure the c5 square for the black queen's knight.

8...h6 pushes the bishop off the c1-h4 diagonal which black will later occupy with his own bishop (14..Bh6).

The move ..Qe8 breaks the pin on the kings knight and also covers the a4 square, where black may push the a pawn to further restrain any attempts by white to play on the queenside.

11...Nh7 frees the f pawn to advance, but it also introduces the possibility of trapping the h4 bishop by playing ..h5,..g5 and ..h4. The ..h5 push that is part of this plan frees h6 for the g7 bishop, with the intention of playing ..Be3 if allowed to.

The way Gallagher writes all the elements of blacks plan seem fit together very well, I recommend his book. If you are over ~1800 or know the KID quite well already then I suspect his other book 'Play the King's Indian: A complete repetoire in this most dynamic of defences' is a better buy.

Jan-10-11  kdogphs: the move Nbd7 takes up three chapters in "Dangerous Weapons: The King's Indian" by Palliser, Dembo, and Flear but only after White castles. I have played this variation three times on and I have a 66% score as Black... so far so good!!!
Jun-10-13  xombie: Well I am going to buy this book. I am a devotee of the KID Petrosian as white - the game unfolds beautifully. Although Gallagher wrote his book as a 'repertoire' book for black, I am hoping that it will help understand the formations in a general sense.
Jun-10-13  parisattack: In the book 'Petrosian's Legacy' there is a nice chapter on how he came to his fondness for Bg5 in the QP openings.
Mar-02-20  ewan14: Cecil - what if after 8 ... h6 white

plays 9 Be3 hitting c5 ?
