KID Bayonet attack (White)

Since the theory for the KID seems to change every day right now, is the 9.b4 line of the KID (The Bayonet Attack) considered best for white? Of particular interest to me is the line 9.b4 Nh5 10.Re1 f5 11.Ng5 Nf6 12.f3 (Or Bf3, IDK which one is more popular right now) 12...Kh8 13.Ne6!? Bxe6 14.dxe6 Nh5 as in the game Van Wely - Radjabov Corus 2007 which Radjabov won handily.

I'm also curious about a couple of Magnus Carlsen moves that he has used recently - first 9.a4:

and second 9.Kh1!? which I really like, it seems the plan is simply to shove the rook on the g file, push the g pawn, and mate:

I'm rather new to this type of position but I've noticed that the pawn formation c4-d5-e4 gives white a space advantage but I can't see how it can be decisive. Anyway, I am still looking over these games, thanks for posting them, it gives me some ideas.

Well that's all mainline stuff, move 9 seems to be where white really decides how he's going to play - 9.b4 seems to say white's taking over on the queenside whereas 9.Kh1 seems to be white striking back on the kingside.

interestingly enough, I've never faced the bayonet attack...maybe I'll look at Play the King's Indian when i get home (posting this in computer lab at school...who pays attention in french class anyways?)

Well I don't take French, but who pays attention in Spanish or German class anyways? springs to mind. Yeah, I'm curious what PTKI has to say about it. I'm actually not that surprised that you haven't seen the Bayonet Attack yet, it seems like a lot of white 1.d4 players don't want to get into deep theory - maybe not, but it sure does seem that way based on what I've seen.

Have you seen 9.a4 or 9.Kh1 though?

Van Wely has played that line extensively. He's fought an attrition war with Kotronias in that line, and I believe he has said at some point that it is winning for white.
I may have some of his analysis (in a dutch chess magazine) lying around somewhere.

Ah, thanks for the info. Have you ever used the line?

Bxe6 14.dxe6 Nh5 as in the game Van Wely - Radjabov Corus 2007 which 4 36. Re2 Rc3 37. Qb2 h5 38. h3 Qd1 39. Bb3 Rxb3 40. axb3 Nxe6 0-1

Well, this is deep theory stuff and well beyond me. So far, Van Wely - Radjabov have reached 14. dxe6 three times. In the FIDE World Cup 2005 Radjabov played 14. ... fxe4 and lost in 40.
Radjabov decided that was clearly not on, so in the 2007 Amber Blindfold played 14. ... Nh5. Van Wely responded 15. c5, losing in 74 moves.
Van Wely's new move this game was 17. g4 and he still lost. Incidentally, Shirov in the same Corus tournament played 17. Kg2, also losing.
Objectively speaking, Black seems to have the edge.

I have seen a4, but I've run into the 4 pawns and fianchetto more than anything else (sorta strange) But yea, a lot of d4 players wanted avoid tactical, theoretical games (or they would play e4) which is a reason why I play the KID, it presents them with something they generally dislike.
