If you are looking for a possible alternative for black on the line you are mentioning coming from Accelerated Dragon. Options are 8...a5 (Instead of 8...d6) Uoegele Variation I believe is the name. I drew one corr. game many years ago. Also I read somewhere that 8...e6 was played by GM Spangerberg. Even 8...Re8 played by Dubov.

I never disputed this.  Problem is that 10.h4 (it's not mine; GM Velimirovic already played it in 1963) is a rare move, so taking up the Soltis just for this specific move order is rather overkill.

Let me save you some time and work: 10.h4 Nxd4 11.Bxd4 b5 12.h5 is good for White.

Yeah, I misunderstood until Bragesjo's last comment.

This however is irrelevant for my question (perhaps point); I'm interested in 1.e4 c5 2.Nf3 Nc6 3.d4 cvxd4 4.Nxd4 g6 5.Nc3 Bg7 6.Be3 Nf6 7.Bc4 O-O 8.Bb3 d6 9.f3 Bd7 10.h4 not Rc8, from both White's and Black's point of view. I'm pretty sure it won't be something with Bh6 as long Her White Majesty is still on d1  .

Thanks for clarification. What does he recommend against

10.h4 Nxd4 11.Bxd4 a5 and after  10.h4 h5 11.Qd2 Na5/Ne5 (iso 11...Rc8) ?

That's not what I wrote. What I did write is that I'm a bit disappointed that GM Negi recommends transposing to the main line and apparently doesn't trust independent options for Black, especially the two I mentioned.

Negis book (GM repertour) is written for whites point of view and has one of the lines as main. I belive the early h4 was hes backup line. 

The lines I posted here are comments by an other author who made these comments about Negis books lines and why he did not recommend Bc4 yugoslav in hes book "Dismantling sicilian", also written from whites point of view as well. Dismantling book has an extra chapter where the author explaines why he did not choose certain lines and the posts here is why he went for Marocy vs accelerered and 9 000 vs dragon instead of Bc4 yugoslav.

I start this new thred to separate discusion from an other thread.

Negis book goes for Bc4 yugolav and the lines has no drawback that they lose by force, only allowing an equal position.
The line in gives here are part of "Dismantling the Sicilian latest edition" where the author has a chapter called "What other recomends and why I disagree".

That chapter is usfull for every sicilian player no matter of system and not only for white. I agree on most drawbacks on every variation.
I divided the posts to make in easer to read.

Shaws book is newer so it is not mentioned by I agree on the drawback in English attack based on my own corr games in a line where engines
first thinks white is pawn better but some computer moves later its equal.
Dismatling ddi by they way go for Marocy bind vs accelerated and 9 0-0-0 yugoslav vs Dragon.


Note from the moderator: that other thread Bragesjo refers to is probably this one.
