Learning The King's Indian Attack

I haven't watched these particular videos, but I'd recommend the one by Dereque Kelley as I've liked all the opening videos I've seen of his. He is great, and you get to share the beautiful view from his apartment as a bonus when you watch his videos!

There's a group devoted to that opening:

I could also post a KIA game or two from my OTB tournaments, if you like.

Yes, thanks for sharing that game. One gets the feeling the queen side is overrated altogether after playing through the one you just shared.

Fischer vs Myagmarsuren is also worth looking at:

... and here are Fischer's own annotations to that game. If you have a hard time reading them, you can copy-and-paste the image of the page into Paint and expand it.

That was a very interesting game blueemu.
The KIA seems very effective against the French structure.
At a first glance, I say I would have played 9...f6 to get rid of your pawn.
If you take I have to recapture with the knight, and e6 could have been a liability, but maybe, if I play Bd6, Qc7, Re8 I can manage to push it to e5.
