Gee, I wonder what White's strategy is here? :-)

Jan-19-09  Akavall: <KingG> Thank You.
Jan-19-09  Akavall: I think that Aronian vs Radjabov, 2008 is actually a Benoni,

After white's 9th move they have this position:

Jan-19-09  KingG: <Akavall> Yes, against the Fianchetto lines, play can often transpose into a Benoni or a Grunfeld. Play can also transpose into a Benoni in other lines as well. For example the Averbakh(1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Be2 0-0 6.Bg5 c5 7.d5, for example) or the Samisch(1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3 0-0 6.Be3 c5 7.d5). In general, Black can almost always choose whether to play the traditional KID move ...e5, or to play the more Benoni-like ...c5. Personally I would play ...e5 against everything except the Samisch, where I think 6...c5 has shown itself to be the best move, and perhaps the Fianchetto variation which can be a bit of a headache, and where transposing into a Benoni is probably as good as anything else.
Jan-19-09  Akavall: Yeah, I think the only line where black can't play ...e5 is the four pawn variation:

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f4 O-O 6. Nf3

Where black normally plays 6...c5, and after 7. d5 it turns into a Benoni type position.

Jan-19-09  KingG: <Akavall> Yes, I forgot to mention the four pawns attack. But Black can still play for ...e5 if he wants, he just has to play ...Na6 first(or maybe not, Mamedyarov vs Svidler, 2008).
Jan-19-09  Akavall: I didn't realize that 6...e5 was playable in that position! And an interesting game.

Gee, I wonder what White's strategy is here? :-)

I think you answer it partly when you comment on Radjabov's b6 where you make some good points - I think if White can make weaknesses on the Q-side the he could penetrate but the position is dynamically tense and complex so Radjabov uncoils like a spring.

Another idea for White is the b6 thrust...

Maybe White is trying to crack the Black Pawns - and Black has to be careful - with c6 or b6

Premium Chessgames Member
  Richard Taylor: A possible continuation (Idea only)

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Be2 O-O 6. Nf3 e5 7. O-O Nc6 8. d5 Ne7 9. b4 Ne8 10. a4 f5 11. a5 Nf6 12. Bg5 Nh5 13. exf5 gxf5 14. Qd2 Nf6 15. c5 Bd7 16. b5 Be8

17. b6!?

axb6 18. axb6 Rxa1 19. Rxa1 cxb6 20. cxd6 Qxd6

21. Nxe5!?

click for larger view

Qxe5? ( 21... Ned5 or poss. 21..Ne4) when 22. Bf4 seems to win

But Black has tricky moves such as Ne4 at various points

But I haven't checked it with a computer..

Jan-19-09  Towershield: Richard Taylor: <But Black has tricky moves such as Ne4 at various points> Yep thats why 21.Nxe5 is a mistake; 21...Qxe5 22.Bf4 Ne4 23.Bxe5 Nxd2 24.Bxg7 Kxg7 . 21.Ra7 might have been better.
Premium Chessgames Member
  Richard Taylor: The idea is to "strike at the base of the pawn chain" = whether that makes sense in this complex position I'm not sure.
Premium Chessgames Member
  Richard Taylor:

Yes - I thought Nxe4 was dodgy - and I forgot the pin on the knight also. Altho I was looking to Q sacs on c3! And the d6 thrust might work but Black's pieces on the K-side are like a whole lot of bunched muscles on a boxer waiting for a right hook !!

But in the position above White must have a good game as Black's pawns are doubled - at least White must have good chances.

Jan-19-09  Ulhumbrus: An alternative to 18 Nh4 is 18 Ra4, after which Rfa1 or Ra4-h4 may follow.
Premium Chessgames Member
  Richard Taylor: Yes Ra7 looks good

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. Be2 O-O 6. Nf3 e5 7. O-O Nc6 8. d5 Ne7 9. b4 Ne8 10. a4 f5 11. a5 Nf6 12. Bg5 Nh5 13. exf5 gxf5 14. Qd2 Nf6 15. c5 Bd7 16. b5 Be8

Possible (probably dubious) line - of course not forced!

17. b6 axb6 18. axb6 Rxa1 19. Rxa1 cxb6 20. cxd6 Qxd6 21. Ra7 Nexd5 22. Bc4 Bf7 23. Rxb7 Ne4 24. Nxe4 fxe4 25. Rxf7 Rxf7 26. Bxd5 exf3 27. Bxf7+

Oh well all the Fritz and Rybka people will demolish whatever the human can come up with!

Jan-19-09  shintaro go: This Bayonet, unfortunately, got stuck in Ivanchuk's throat. Moro and Chucky are having bad starts in this tourney.
Premium Chessgames Member
  Eyal: This should sound familiar by now...

<28.Rg1 Qf7. By this stage of the game, Ivanchuk was down to barely a minute on the clock, to reach the time control at move 40 [...] Radjabov himself had only about ten minutes, but in such a complicated position, such a lead on the clock is almost worth an extra piece.> (

Premium Chessgames Member
  Eyal: Radjabov talking about the game:

He criticizes 15...Bd7?! suggesting as a better alternative a6, stopping b5. 23.g4! came as a "total shock" to him, but he's pleased with 23...Nfg8!? which he thinks was the best practical chance to keep the position afloat. Still, he's convinced White was significantly better at that stage, although he couldn't see a forced win.

Jan-20-09  jovack: Open King + enemy queen = all your pieces picked off via forks
Jan-21-09  OneArmedScissor: Radjabov is better with the black pieces than he is with the white ones.
Premium Chessgames Member
  Eyal: I'm not sure he's better, but many times he certainly seems to be in a more ambitious mood when playing Black.
Premium Chessgames Member
  Eyal: ...Or, as Mig Greengard has put it: <Radjabov is doing his usual routine of offering up quick draws with white so he can rest up for do-or-die battles with black, especially in the King's Indian.> (
Jan-21-09  VinnyRoo2002: That's true, as much talent as Carlsen and other youngsters have, none of them win as often as Radjabov with black. If he can become a better player with the white pieces, he could be the front-runner to be world champion out of the young bunch. I think that's a challenge that Radjabov has to put on himself because right now, he is very ordinary with white.

After 21 Nxe5 Qxe5 22 Bf4,
in addition to Towershield's 22..Ne4,
22..Qxc3 23 Qxc3 Nfxd5 also looks strong, eg
24 Qc1 Bxa1
25 Qxa1 Nxf4
26 Bc4+ Bf7
emerging with a R, 2 Ns and 2 Ps for Q.
