9. Qf3 Be7 10. Qc3 Na6 11. Be3 O-O 12. Nxa7 Bg5! (12...f5 +=, Fedorovsky - Markos). Here instead of 13. Bxa6 Bxe3 14. fxe3 =, corr. game Grayland - Adams above, my analysis went 13.Nb5 Bxe3 14.Qxe3 Bf5 15.Bd3 Bxd3 16.Qxd3 Nc5 17.Qc4 Ra4 18.b4! ... +/-.
I had overlooked 14...f5! 15.Qa3 Rf6 =, later found by Klaus Kögler, e.g. 16.0-0-0 Nc7 17.Qb3 Na6!, when White can offer a repetition (18.Qa3 =), or play something else, also =.

Stefan,

I may be asking you to steal your own thunder for your next article, but I didn't see your original article.  What was it about 9...Be7 that you underestimated?

Jeroen Bosch wrote on 9.Qf3 in NIC Magazine 2003, No. 5, the article also appeared in SOS vol. 1 (2004). My own article on 9.Qf3 in Kaissiber #28 (July 2007) took a lot of time, and I'd still recommend 9.Qf3, since Black can easily go wrong, and other Sveshnikov lines are not better. Objectively 9...Be7! (which I underestimated in 2007) equalizes, as does my main line 9...a6 10.Qa3 Be7, but I have some new ideas for White for a planned update in one of the next issues.

Thanks for the responces guys .
Well, i agree that 9.Qf3 can be tricky for blitz or rapid , but generally gives black good play either he plays a6 or simple ignores it and continues to develop .

@zoo :
If black moves 2..e6 i switch to Alapin 3.c3 , sideeffect is that i take out lines with Bg4.
Yes , Ne7 is also playable and needs to be prepaired.
I dont get your idea with a e5-e4 gambit , where does it appear ?

So , i stick with the 9.c4 main line and may come up with some questions there ^^ .

The Qf3 idea is tricky and quite dangerous in rapidplay or against an opponent who is unfamilar with the ideas. I had to work hard to win the following corres game as Black, but I was quite pleased with some of the dynamic ideas I came up with:

[Event "BCCA ch 2002-3"]
[Site "?"]
[Date "2002.10.??"]
[Round "?"]
[White "Grayland, Stan J"]
[Black "Adams, Phil"]
[Result "0-1"]
[ECO "B33"]
[PlyCount "82"]
[EventType "tourn (corr)"]
[EventRounds "11"]

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Nd5 Nxd5 8.
exd5 Nb8 9. Qf3 Be7 10. Qc3 Na6 11. Be3 O-O 12. Nxa7 Bg5 13. Bxa6 Bxe3 14. fxe3
Rxa7 15. Bd3 Qh4+ 16. g3 Qg5 17. Qd2 e4 18. Bf1 Bd7 19. Bg2 Bb5 20. a3 Rc8 21.
Bf1 Bd7 22. c4 b5 23. Qd4 Rac7 24. b3 h5 25. a4 bxa4 26. bxa4 Rb7 27. Be2 Rb3
28. O-O h4 29. Rf4 hxg3 30. h4 Qh6 31. Rxe4 Rcb8 32. Rf4 g5 33. Rf6 Qxh4 34.
Qxh4 gxh4 35. a5 Bh3 36. Rd1 Rb1 37. Rf4 Rxd1+ 38. Bxd1 Rb1 39. Rd4 f5 40. a6
Ra1 41. a7 f4 0-1

Indeed, Black plays 9...Be7, 0-0 and doesn't care for White's tricks towards d6. In the end the Queen is not so well in f3 or a3.
Some remarks en passant about this 7.Nd5 sideline, from White's point of view:
1. you can't be sure to have it on the board against every sviechnikov, since Black can use the 2...e6 move order, when this option is missing. Either avoid the transposition, or prepare a main Bg5 line.
2. Black often goes ...Nb8 but the old plan ...Ne7-f5 is not so bad either, you should also prepare for that ;
3. in the ...Nb8 mainline Black has an attractive gambit by means of e5-e4, after which you'll be under attack. It may take a few games to meet this gambit, and a few more to see if you like it. I don't.

I just ran some stats.  There are about 110 games with 9.Qf3 in my database.  Black usually responds with 9...a6, but I prefer 9...Be7 which gives BLACK a winning score!

It seems that the whole reason for playing 9.Qf3 is to respond to 9...a6 with 10.Qa3.  So, if Black doesn't play along, he gets a great game.

After 9.Qf3 Be7 10.Qc3 Na6, White has always tried 11.Be3 0-0, winning the a-pawn and (usually) losing the game.

One of the most recent games was Fedorvsky-Markos, 2007 (see below).

[Event "Pardubice Czech op"]
[Site "Pardubice"]
[Date "2007.07.21"]
[Round "2"]
[White "Fedorovsky, Michael"]
[Black "Markos, Jan"]
[Result "0-1"]
[ECO "B33"]
[WhiteElo "2400"]
[BlackElo "2559"]
[PlyCount "90"]
[EventDate "2007.07.20"]
[EventType "swiss"]
[EventRounds "9"]
[EventCountry "CZE"]
[Source "ChessBase"]
[SourceDate "2007.09.04"]

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Nd5 Nxd5 8.
exd5 Nb8 9. Qf3 Be7 10. Qc3 Na6 11. Be3 O-O 12. Nxa7 f5 13. Bxa6 f4 14. Bc5

I didn't see any advantage either.  What is white's plan, apart from general development, especially if you can't generate enough play against d6?

I don't think Black has an advantage either, mind.  But his position looks easier to play.

I don't see how White has any advantage in the given game if Black avoids the generally dubious ...e4, preferring instead 15...Nd7 with the intention of 16.fe5 Ne5.

If you want to put the test to the Sveshnikov, play 7.Bg5 a6 8.Na3 (8.Bf6 gf6 9.Na3 is an interesting move order since 9...f5 isn't as convincing as 9...b5) b5 9.Bf6 gf6 10.Nd5 f5 11.Bd3.
  

All our dreams come true if we have the courage to pursue them.

Makes it sense to study this line , ( i like because its not so common ) , especial with the 9.Qf3 approach :

* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
* * * * * * * *
*

I knew 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Nb5 d6 7.Nd5 Nxd5 8.exd5 Nb8 , leads to at least equal chances with 9.c4 i think ? , any improvments nowadays ..?

9.Qf3 a6 10.Qa3 Be7 11.Bg5 f6 12. Bd2 0-0 12.Bb4 Qd7! doesnt work ..

The only idea comes to my mind is to skip pressure on d6 ..
