Yes.  I suspect that Black's decent score has more to do with surprise value than the objective strength of this move order.  White does have considerable freedom here to put his/her pieces on optimal squares with little compensation for Black...

Did some more checking on 8 Nc4, but I think the pawn sacrifice is not as good as I thought. White should follow up with f3 probably, but I dont see much tangible.

8 exf5 Bxf5 9 Nc4 Nd4 10 Ne3 Be6 11 Bd3 followed by 0-0, Ncd5 and c3 and maybe even c4 looks very good to me, after all that is where you would want your knights and you my be able to develop the c1 bishop to the a3-f8 diagonal. I dont see much potential for black's counterplay like in the similar c4 variation. There is no way you can break the grip on the white fields.
The other variation with 8 exf5 as in the game also looks very decent to me for white.

Note that I am not saying white is winning, I am just saying that I think white is a bit better.

This does look interesting, and seems to score rather well in practice.  According to the 18 games in the www.chesslive.de database, Black has a decent score, though I don't see any household names on either side in any of the games.

A couple of wins for White are below, one involving the previously mentioned 8 exf5, and another playing the thematic 8 Nd5.  I'm not sure either involves a win out of the opening, but they might be worth some analysis.  Willempie and Dutch-Kalashnikov both suggest 8 Nc4, which I couldn't find.  Maybe it would be worth investigating that move further.

Jan Pinski & Jacob Aagard cover in their book about the Kalashnikov the 7..Be7 line but not this variation.
I faced 6.N1c3 a6, 7.Na3 f5 already 2 times in tournaments. Basically I dont share the opinion that it is premature, otherwise you can say this of many Kalashnikov lines.
But 8.Bc4 made in practise Black suffer very hard.

Well I think that there is a reason Nataf for example plays f5 against the c4 variation, but not against the N1c3 one. I think one of the reasons is in the exf5 variation. I think it is premature as white has enough time to cover d5 and e4 properly.

PS I think f5 is often premature, it just happens to be playable when you can generate enough piece play.

I am sure that 6.N1c3 a6, 7.Na3 f5 is absolutely playable. If it would be premature, you could say the same from a lot of well established opening variations that include a rather early f7-f5, for example in the Rossolimo 1.e4 c5, 2.Nc3 Nf6, 3.Bb5 d6, 4.Bxc6 bxc6, 5. 0-0 e5, 6.c3 f5 played for example by Movsevian, Sveshnikov, Lautier und Chr.Bauer!

Well you have effectively swapped in Bd3 and c4 for Ne3, which I think should be beneficial for white. With the bishop still on f1 I think c4 is now a positional threat.
Still it is playable for black I think.

not that I dont believe that this is a positional disadvantage;
but accepting positional defects for the purpose of getting attacking chances in the middlegame, thats what all the Kalaschnikov/Sveschnikov-family is about. From the point of endgames/positional aspects nobody would play these openings.

Did some more checking:
8.exf5 Bxf5, 9. Nc4 Nd4, and here I like 10 for white Ne3 iso Bd3. Now you have a sort of mirrored french structure with the holes on e4 and d5 firmly under white control.

Will give a more detailed answer when I am home.
I dont see the problem so far with the fxe4 variation. It costs a pawn but blacks structure is a mess.

I dont know if it is strategically a problem to allow Nc4. But on the short-term I see no problem, tell me if I am wrong.

8.Nc4 Nf6, 9.Bg5 Be6 (OK, upon 10.Bxf6 you must take gxf6 but this is not the only Kalashnikov variation where this happens).

8.exf5 Bxf5, 9. Nc4 Nd4, 10. Bd3

All variations without the usual b5 allow Nc4. But I think, not in the 8th move, as after b5 and then b4 black can play fxe4.  More dangerous is 9...Nc4.

Cant white just play 8 Nc4 or maybe even 8 exf5 9 Nc4?
Looks quite good to me for white (I play the N1c3 variation as white).

I doubt whether this forum is the right place for my question; it seems that most people who discuss here, are more interested in the classical Sizilian or the Sveschnikov.
