A disclaimer. Not all variations completely correct, but they will hopefully inspire the reader to understand some of the thought processes of the non-master level player/annotator.

1.Nf3 d5 2.g3 c5 3.Bg2 Nc6 4.0–0 e6 5.d3 Nge7 6.Nbd2 g6 7.e4 Bg7 8.Re1 0–0

This is the standard setup I prefer against the King's Indian Attack. It makes it more difficult for white to attack the kingside, while in the meantime black can try to attack on on the Queenside. I have included some brief examples.

9.c3 b5

The following is the standard Modern way to follow up, but 9...b5 is not unheard of.
[9...d4
A) 10.cxd4 Nxd4 11.Nxd4 A1) 11...cxd4? 12.Nc4±
(12.e5 Nc6 13.f4 Bd7 14.Ne4 Nb4 15.Qb3 a5 16.Bd2 Nd5 17.Qxb7 Rb8 18.Qa7 Rxb2 19.Qxd4 Qb8 20.Nc5 Rxd2 21.Nxd7 Rxg2+ 22.Kxg2 Qb7 23.Kh3 Qxd7 0–1 Zahorbensky,J-Petuchov,S/CZE-chT1b 9697 1997/EXT 97) ;

Damljanovic,B-Costa,J/Mitropa Cup 1991/CBM 26/[Horn,Pe]/0–1 (51);
B) 10.c4 10...e5 11.h3
(11.Nf1 f5 12.exf5 gxf5 13.Nh4 Ng6 14.Nxg6 hxg6 15.f4 exf4 16.Bxf4 Qf6 17.h4 Bd7 18.a3 Rae8 19.Qf3 Kh7 0–1 Chalus,K-Svoboda,M/CZE-chT1a 9697 1997/EXT 97)

And then there are a couple other tries that look interesting...
9...b6;
9...Qc7]

10.e5

(All supplemental games were truncated to save space.  As they were meant to illustrate the opening, I took this liberty. If you have a database, there are alot more games in this line. Wink!)
Up to this point, we had both rattled out the moves.  Now the real game begins, cause we both have to think about what we're doing.  Even at Our level (rather low), theory still has to be followed, or you usually get a bad middlegame.  Welcome to the Machine!

10...Rb8 11.a3 a5 12.a4 Is this a timewaster or what?
(I must say that a3-a4 pushes like this are usually a statement that goes like this, "I can do whatever I want and you can't do anything about it!". (snub, snub...)

[35...Kf7 with the Idea of Ke7, Be8-f7, and e5 seems to be a better plan than instituted in the game.]

56...Qxb2

[56...Qe3+ 57.Kg2 Qe2+ 58.Kg3 I had a perpetual check draw for the taking... At the end of an intense
4 hour game, after escaping the complications with a better position (!), one tends to harbor delusions of grandeur, so I played for a win, and managed to blow it, of course.]

57.Qa7 Qe5+ 58.Kg2 Qc7 59.Qa8 d4

[59...Qf7-+ With Dave McCraw's idea of ...Bc4,...b3.  This could win. ]

60.Be4 Bf7

[60...Kg7!? Even at this point I had a good move. (escapes the pin)]

61.Qf8 Qf4 62.Qh6+ Kg8 63.Bxg6? Bxg6??

[Oh, I could have said checkmate... Argh! 63...Bd5+ 64.Kh3 (64.Kg1 Qg3+ 65.Kf1 Bc4+ 66.Bd3 Bxd3#) 64...Qf3+ 65.Kh2 Qg2#]
