What is the winning moves for White-KIA Opening?

Now that you have joined the KIA inc club you will find information in the group forum. You should also join the group vote chess games (highly recommended). We currently have nine games in progress and start a new game about once a month and try to cover all the significant variations of the KIA, discussing what moves, when and why.

See you there. 

Chess is a forced draw and that looks like a hippo to me.

The KIA is discussed in Winning Chess Openings by GM Yasser Seirawan.

It was part of a seven part series of chess books. Here is a review of three other books in the series:

For more on the KIA, one could try The King's Indian Attack: Move by Move by Grandmaster Neil McDonald. Perhaps, it would be of interest to look at The Fianchetto Solution by Emmanuel Neiman and Samy Shoker.

"... For players with very limited experience, I recommend using openings in which the play can be clarified at an early stage, often with a degree of simplification. To accomplish this safely will take a little study, because you will have to get used to playing wiith open lines for both sides' pieces, but you can't eliminate risk entirely in the opening anyway. ... teachers all over the world suggest that inexperienced players begin with 1 e4. ... You will undoubtedly see the reply 1 ... e5 most often when playing at or near a beginner's level, ... After 2 Nf3, 2 ... Nc6 will occur in the bulk of your games. ... I recommend taking up the classical and instructive move 3 Bc4 at an early stage. Then, against 3 ... Bc5, it's thematic to try to establish the ideal centre by 4 c3 and 5 d4; after that, things can get complicated enough that you need to take a look at some theory and learn the basics; ... Of course, you can also play 1 d4 ... A solid and more-or-less universal set-up is 2 Nf3 and 3 Bf4, followed in most cases by 4 e3, 5 Be2 and 6 0-0. I'd rather see my students fight their way through open positions instead; however, if you're not getting out of the opening alive after 1 e4, this method of playing 1 d4 deserves consideration. ... a commonly suggested 'easy' repertoire for White with 1 Nf3 and the King's indian Attack ... doesn't lead to an open game or one with a clear plan for White. Furthermore, it encourages mechanical play. Similarly, teachers sometimes recommend the Colle System ..., which can also be played too automatically, and usually doesn't lead to an open position. For true beginners, the King's Indian Attack and Colle System have the benefit of offering a safe position that nearly guarantees passage to some kind of playable middlegame; they may be a reasonable alternative if other openings are too intimidating. But having gained even a small amount of experience, you really should switch to more open and less automatic play." - IM John Watson in a section of his 2010 book, Mastering the Chess Openings, Volume 4

3. d4 and 4. c4 transposing to a Catalan would have been a better way of taking advantage of Black's inaccurate 2nd move 2. ... Nc6.

The position of Black's Bishop on f5 also gave you the option of playing the position as a reversed Panno (instead of a reversed Classical) King's Indian, with 6. Nc3 since you can answer 6. ... d4 with 7. e4 hitting the Bishop, or answer 6. ... e4 with 7. dxe4 followed by Nh5 again hitting that Bishop.

The combination of Nc6 and Bf5 is not a particularly good system against the KIA.

I think at one point you would have this position with white

then you would attack

Or.. this (in Qc7 positions):

These days players of the Black pieces rarely play e6, d4, B-e2 or d6 etc. and give White  a standard Kingside attack with Re1, e5, Bf4, h4, Nf1

There are many ways for Black to get a comfortable game with winning chances.  Top players like Sirawan can use the KIA as one of their main weapons because they understand how to handle a complex positional struggle where they may have no real advantage.

Amateurs learn the KIA because they are lazy and want to learn something they can play against anything Black might try.  Then they make the ridiculous demand that their lazy man's opening has to be winning for them.

If it were always a win for White then whatever would they do when they have to face it as Black?

Black has the classical (or whatever it's called) pawn structure with pawns on d5 and e5. So White needs to try and undermine and break up this center to give White more space for his pieces. So the first move that sticks out to me is 7.c4 and it happens to be cool because there are some nice tactics waiting due to Black's king in the center.

7...d4 is not so great for Black due to the tactical idea 8.b4! (playing against the pawn on e5) Bxb4 (8...Nxb4 9.Nxe5) 9.Nxe5 Nxe5 10.Qa4+ Nc6 11.Bxc6 bc 12.Qxc5.

Even 7...O-O is not working due to 8.cd when Black can't capture back due to the threat of e4 pinning two pieces. 

7...e4 8.Nh4 is no good either.

7...Be6 tries to hold d5 but then 8.Ng5 is annoying.

So Black is kinda in trouble.

Also you should play 4.d3 in this position so that Black can't kick your knight away with ...e4.
