The line u are discussing is in fact quite new, it only came into play in early 90ies. Note the whole point is that black develops 6... a6 7 Be3 Qb6 and wait with Nc6 for later. In this way he stop white continuing the normal Qd2 as b2 is hanging.The fact is that white so far has a miserable score vrs this line, and one of the few  that scores well is Kasparovs 9 dxc5, while  9 Be2 has miserable statistics.

OK and thanks for the games references...
I recorded 12...Rb8 Bobras-Baklan,Capelle la Grande 2002 and 8.Rb1!? as other interesting ideas.

This morning, I quickly analyzed the line and 8.a3!? Nc6 9.Be2 Qa7 10.oo leads to one middlegame hard (to me) to evaluate. Example:10...cxd4 11.Bf2 (11.Nxd4? Bc5) Bc5 12.Na4 d3! 13.Bxd3 Bxf2+ 14.Rxf2 Qe3 and White has some problems with his f4 and e5 pawns. With e5 pawn, because if White exchanges too much pieces then pawns will become weak: 15.Qd2 Qxd2 16.Rxd2 b5 17.Nc3 h6 18.Ne2 g5

In the game Timman-Radjabov, Malmoe 2001...why not 9.Be2 Qa7 10.Na2 Qb6 and a draw proposal ?

Maybe Garry relied on an old (2001) analysis by Finkel, which went:

9.dxc5!? Bxc5 10.Na4 Qa5+ 11.b4 Qxa4 12.bxc5 _d4_ 13.Nxd4 Nxc5 14.Nb3 Nxb3 15.cxb3±;

This evaluation was rebuked by Gurevich the year after the game Kasparov-Radjabov:

9.dxc5 Bxc5 10.Na4 Qa5+ 11.b4 Qxa4 12.bxc5 _0-0_ 13.c4 Qa5+ 14.Qd2 Rd8 15.cxd5 exd5!? with counterplay in Grischuk,A  - Gurevich,M (2634) [C11]

I have the same question, but on previous move: "Why Kasparov played 9.dxc5 versus Radjabov in 2002 game ? (and not Be2) "

Maybe, a6-Qa7 is one good system for Black vs Be2 ?

(Radjabov won a game one year later with the system versus Marjanovic. Marjanovic-Radjabov, Halkidiki 2002)

Anyone here who knows why Radjabov's Qb6-a7 idea has disappeared from praxis? I only know that Radjabov played it a few times a few years ago, without losing any game I think. So why did he drop this cool idea??

An example for those who don't know what I'm talkin about:

Timman,J (2620) - Radjabov,T (2533) [C11]
Sigeman & Co Malmoe (6), 17.06.2001

1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.e5 Nfd7 5.f4 c5 6.Nf3 a6 7.Be3 Qb6 8.a3 Nc6 9.Be2 Qa7 10.Na2 cxd4 11.Nxd4 Bc5 12.c3 0-0 13.b4 Bb6 14.Bg4 Nxd4 15.cxd4 Nb8 16.Qd2 Nc6 17.Rd1 Bd7 18.Nc3 Ne7 19.0-0 Rac8 20.Rf3 f5 21.exf6 Rxf6 22.Bf2 Nf5 23.Bxf5 Rxf5 24.Re1 Rc4 25.Ne2 Rf8 26.Rc1 Rxc1+ 27.Nxc1 Bd8 28.Nd3 Bf6 29.Ne5 Bxe5 30.dxe5 Qb8 31.Bc5 Rf7 32.Qd4 Qc8 33.h3 Bb5 34.Kh2 Bc6 35.g4 Qd7 36.Kg3 Qc8 37.Rf2 Bd7 38.Rf3 Bc6 39.Rc3 Qd7 40.Bd6 Qe8 41.Rf3 ½-½

I add just some game references about June2004 update 11.Qf2!?

11...Bxd4! (11..Nxd4 12.Bxd4 Qc7 13.Bd3 f6!? Kavalek) 12.Bxd4 b5 13.Kb1 (Arnason-Gurevich,Reykjavik 1988) or 13.Bd3 (Mainka-Lautier,Dortmund 1989 given in Psakhis and Tiemann's books ; and Kosanovic-Popovic,Stara Pazova 1988 given in Short's book)

Maybe 11...Nd7 is one good move (and not Nxb4 or Ne4 giving weaknesses to Black on queenside or center pawns).

And if : 12.a4 bxa4 13.Nxa4 Rb8 14.c3 f6 15.Nd4 Nxd4 16.cxd4 fxe5 17.dxe5 Qe7 18.Rc1 oo 19.Nc5 g5 or 12.Ne2 f6 13.Ned4 Nxd4 14.Nxd4 Qb6 15.exf6 Nxf6 (White now has a piece on the d4 blockade square but Black has now some play on e4 square and f-file)

C11: Classical (Boleslavsky) variation..11.b4!?

In Classical variation:
1.e4 e6 2.d4 d5 3.Cc3 Cf6 4.e5 Nfd7 5.f4 c5 6.Nf3 Nc6 7.Be3 (Boleslavsky) a6 8.Qd2 b5 9.dxc5 Bxc5 10.Bxc5 Nxc5
the move 11.Qf2 is usually played (I refer it as "Nunn's variation" and the game refence is Nunn-Nogueiras 1989  ; you can compare with the same idea in the variation given by McDonald in June 2004's update).

But what's about 11.b4 !?

It's a common strike in the classical variation and only some players have played it (according to Chessbase-online database)
