I like the blog. I prefer the Four Pawns Attack for White though. It's really fun, and if your opponent doesn't really know what they're doing, you can beat em really easy. In my blog, there is a game of me play the Four Pawns Attack and murdering Black. Please check it out and leave a comment =D

Why does Korchnoi hate the king's indian so much? I suspect it's because he likes playing white with it so much and since he's korchnoi he's usually going to win, which makes him give it a bad reputation.

this is my favorite opening I play for black

I AM NEW THIS IS A NICE BLOG

I am used 2 Ne1 instead of Nd2.

Happy face :D

Right, that's the conclusion in his previous book as well. But if you check out games explorer, there is a new idea in the ...Nd7 line with which black has been doing well. I can't look at it right now, but it involves black playing ...dxc5 at a point where Nunn does not even consider this move.

What I really like about Nunn is that in his heart he is a black player in the KID, but he really puts a lot of effort into writing an unbiased book, with insightful commentary, the type which you can only get from a book.

He prefers 9...a5 with the idea of Nd7, holding up white's Q-side attack a bit and preparing the attack on the K-side.

His feeling with both 9..Nd7 or 9...Ne8 is that white is able to win the race on the Q-side.

I only have his older book "The Classical King's Indian". I very much enjoy his writing.

After 9: Nd2, does he actually prefer Ne8 over a5? Or does he simply prefer Ne8 over Nd7 because Nd7 doesn't accomplish its main aim.

I have a copy of Nunn's 'The New Classical King's Indian', here's some of his ideas:

After 9...Nd7 10.b4 f5, he considers the main line to be 11.f3, mentioning that 11.a4 is too commital.

He prefers 9...Ne8 but only in that it gives black an option to leave it at e8 whereas on d7, it doesn't prevent white from playing c5.

Are there some good lines for black that leave the knight at d7 after 11.f3?

No, take a look at games explorer, there is a new idea where black plays dxc5 in the line you posted where white plays a4.

MCO relegates 9 ...Nd7 to a footnote and gives the main line after 9 Nd2 as c5, followed by 10 Rb1  b6  11 b4 Ne8  12 bxc5 bxc5  13 Nb3 f5  14 Bg5  Bf6  15 Bd2 Kh8  16 Bd3  Bg7  17 f3 Ng8

The footnote (pg 603 (i) reads: "In this line White's queenside counterplay happens very quickly so Black should slow it down with either 9 ...c5 or 9 ...a5.  For example:  9 ...Nd7 ?! 10  b4 f5  11 a4 Nf6  12 f3 f4  13 c5 g5  14 Nc4 h5  15 Ba3 Ng6  16 b5 Ne8  17 b6 and White breaks through."

Ozzie, you do feel  9 ...Nd7 deserves a ?!

Here is a little of what John Watson has to say about the ideas behind this position in "Mastering the Chess Openings Vol 2" (pg 231). 

"9 Nd2.  There's a legitimate question whether this move or 9 Ne1 is better. ... (O)nce White plays Nd2 it is unlikely that he will return to defend against, say, the standard pawn attack via ...f5 ...f4, and ...g5-g4.  On the other hand, 9 Nd2 supports more aggressive intentions on the queenside. White's idea is to play c5 (ultimately this is difficult to stop) and then place the knight on c4, which exerts tremendous pressure on Black's queenside and centre. ...  "

"After both 9 Nd2 and 9 Ne1 there are disagreements over whether to 9 ...Ne8 and 9 ... Nd7 is more accurate. ... (a) 9 ...Nd7 protects against c5, with the caveat that after b4 White might play c5 as a pawn sacrifice.  (b) 9 ...Ne8 supports d6 so that a 'traditional' plan with c5, cxd6, Nc4 and Nb5 doesn't threaten the d-pawn or the c7 square.  That may be more important."

This is a blog to capture the ideas for both sides in this highly complex variation.
