I remember reading something about the QID and why it wasn't terribly popular for a long time.  The conventional wisdom suggested that an early ...e6 and ...b6 allowed White to take over the long diagonal, and often get tactical shots such as Nf3-xe5, Nc6xe5 Bg2xRa8, winning.

That similarity, however superficial, to playing ...e6 and ..b6 in the KIA has kept me from even being slightly interested in those positions for Black.  And since I don't like the KIA as White...

I have another reason for not liking ...b6.  I often try the old way of playing, with e6, d5 c5 pawn structure, and eventually a b7-b5 q-side attack is nice.  If I have to play b5 in two moves, I won't be as happy.  It's hard enough to get that sort of attack rolling in the first place!

In other words, It's just a matter of taste, and I think it's icky to play ...b6.  I know, such hard core analysis for free!  You can thank me later.

(BTW Castlerock, I haven't forgotten that I actually owe you some analysis, but I need the games first!)

Cute shot, Castlerock!

Personally, I'd never play that way as Black (e6 and b6 against an e4 opening) because it looks too much like a one-trick pony.  But it obviously worked here!

I know that John Watson recommended an early ...e5 in one of his Play the French volumes.  Maybe you saw it there?

I used to teach somewhat similar lines from black side in French move order.

The line goes 1.e4 e6 2.d3 d5 3.Nd2 Nf6 4.Ngf3 b6 5.g3 dxe4 6.dxe4 Bc5. Developing the Bishop will invite Ba6 and after 8.c4, 8...Qd3 is a distinct possibility. Hence Qe2 was needed. In some lines black plays Be7 and c5 in varying orders. 

Immediate ...e5 is not needed. But it needs to be timed, though. I'm not sure I have my old notes but could check. I don't know if it is Karpov System, but yes there's an outstanding game by Karpov. A-08 0-1. I think I can trace the game if you can't find it.

There's a Karpov System in the KIA?

Is it some sort of anti-theft device????
