The Levenfish Variation is really not much of a problem for a Dragon player who knows how to handle it, but it can be tricky if you’re careless.  Even if you know what you are doing, there are still a lot of lines where white can create attacking formations, and for some people, that’s all they need to feel confident.  We all know that a confident opponent is a dangerous one.

One example of a secondary line that a Dragon player needs to be aware of is this:

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.f4 Nc6 7.Nxc6 (generally, this exchange is dismissed as ineffective, but it gives white a little bit of an initiative) bxc6 8.e5 Nd7 9.Qf3 (white plays primitively, 19th century style) Qb6 10.exd6 exd6 11.Bd2 Be7 12.Na4 Qb7 13.Bd3 Bh4+ 14.g3 Bf6 15.O-O O-O 16.Rae1 Qc7 17.c4

Objectively, this position is equal, but the Levenfish player would be in his element here.  He would probably have an advantage on the clocks as well.

Good point, Alumbrado.  The antidote to the Levenfish is well known.  But playing the position against someone who's willing to play the White side after ...Nc6 may be a bit discombobulating. 

I don't know, since I don't trust the Levenfish as White anyway.  I've seen local experts try it against young "A" players and get terrible positions.  They sometimes win anyway, but it's despite the opening positions.

To the best of my knowledge I have never played the Dragon with either colour but even I know that 6.f4 should be met by 6...Nc6!
  
If sometimes we fly too close to the sun, at least this shows we are spreading our wings.

I trust ChessBase's big/mega databases.  It doesn't contain a bunch of Blitz games played at 2am local time.

I set the filter at 2300 or 2350, which usually weeds out the trashy stuff.  The Levenfish doesn't seem to scare Black very much, but it could be a nice surprise weapon for White if he's known as a Yugoslav player.

With both players having ELO 2300+ White scores even worse after 6...Nc6: 25, 44, 31%, overall 47% with 125 games.
  
The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

In my database the results after 6.f4 Nc6 are 39, 27 and 34%; overall White scores 52% (more than 800 games). The results after 6.f4 Bg7 are 59, 16, 25%; overall 67% (almost 300 games). This confirms Ben Hague's statement.

I think that the reason why the Levenfish scores so well is that a lot of Black players walk into the trap line, 6.f4 Bg7 7.e5 Ng4 8.Bb5+ which skews the statistics.

In Icc's database (help eco2)

the statistics show that the levenfish is the best weapon to kill the dragon!
Is there a trap somewhere?
