@kylemeister. Van Kampen does not analyse specific games other than the opening moves.
Kavalek-Kasparov starts 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 OO 6.h3 e5 7.d5 Na6 (Van Kampen recommends 7...Nh5) 8.Be3 Nh5 9.Nh2 which could transpose to Van Kampen's line 7...Nh5 8.Nh2 Na6 if White would play 9.Be3 (instead of the main line 9.g3) but it is not covered in the video.

That 9...b5 line looks wild and interesting. I'm just wondering how practical it would be to prepare it for a sideline that I've never faced, even in blitz. But I don't know, maybe it doesn't even require much preparation.

Indeed I recall 9. Bg5 putting that line under a cloud not long after the nice Beliavsky-Nunn game.  Seems a bit of an outlier though ...

Just curious, does van Kampen show the (I would think, classic) game Kavalek-Kasparov?  (More generally, one might wonder to what extent he/other young GMs tend to focus on the latest stuff in these opening videos ...)

I hadn't looked at 9...b5 before, and yes, it seems to work
I found 2 correspondence games with this:



white can avoid this with 6.Be3 c5 7.d5 e6 8.Bd3 (when 8...exd5 9.exd5 b5 can be answered with 10.Nxb5) but then 8...exd5 9.exd5 Na6 10.Nf3 (10.Nge2 Nb4 11.Bb1 b5; 10.a3 Nc7) Nb4 11.Bb1 (11.Be2 Bf5) b5 works for black
really interesting, now 6.Be3 just looks inferior to 6.Bg5

Really, Tony37?  I guess I've never believed in these exd5 lines for White very much.  The computer even seems to think that the immediate 9...b5!?, trying to take advantage of White's move order, is pretty much equal.  I remember these ...b5 pawn sac ideas from similar positions (perhaps the Averbakh).

Of course, there's an old line that goes 9...Re8 10.Bd3 Bh6, and I don't remember the theoretical verdict there--maybe White is better, he scores pretty well.  And perhaps 10...Rxe3 (!? or ?!) is worth a shot.  Kylemeister probably knows this stuff better than I do.

But okay, point taken; White doesn't want to play a Benoni position, he wants to play x...exd5 y.exd5, and in that particular position perhaps it's best to remain flexible with 6...Nbd7.  Still, I think that with 9...b5!? Black should be more or less OK, as White's kingside development is very slow:




Edit: For some reason I can't get the PGN button to work, and I had to manually type in "[ pgn ]" and "[ / pgn ]".

What to do after 8.Nf3 (or 8.Bd3) exd5 9.exd5?
Watson analyses various possibilities for black but none of those seems good 

5.h3 Nbd7 was also recommended by Bologan on his ChessBase DVD about the KID. Unfortunately he forgot to cover 5.Nf3 0-0 6.h3, when the ideas connected with 5...Nbd7 no longer work.

As Kylemeister wrote Black can delay castling here and continue after e.g. 5.h3 Nbd7 6.Be3 e5 7.d5 Nc5 with ...a5, ...h5-h4, ...Nh5 and sometimes ...Bh6 to get a grip on the dark squares.
