In his book  "New Repertoire for Black and White" Kaufmann covers a poisonous backup repertoire against the Sicilian around 2.Nc3. 
He avoids the "big" Najdorf and the Sveshnikov but is willing to transpose to some other open Sicilians.

2...d6 is already covered in this thread (Carlsen variation)
2...a6 -> Ne2, g3, Bg2 and depending on Black's reply d3 or d4. 

2...Nc6 3.Nf3 Nf6 4.Bb5 -> sideline of the Rossolimo 
           3... e5 4.Bc4 
           3...e6 ->Taimanov (Fianchetto recommended) 
                    -> or Sicilian 4N (5.Nxc6 and the calmer 5.Bb5) 
                    -> Scheveningen (Fianchetto recommended)
2...e6 3.Ne2 or Nf3 (it is not clear to me) transposing to other lines
          3.c4 gets short coverage, Kaufman calls it underestimated. 
2...g6 -> Dxd4-Sicilian 

Kaufman's book looks like an interesting supplement to Hansen's book and help to build a consistent repertoire around the Carlsen-variation. 
This repertoire looks sophisticated to me. Kaufman is very concise, some additional research might be necessary.

Book arrived today. The book is a complete repertour book for white after 1 e4 c5 2 Nc3 d6 3 d4 where some alternatives to 3 .. cxd4 are covered. The book also looks at alternativves after Qxd4 and not only Nc6 where the book proposed Qd2 with the idea of b3 Bb2 and 0-0-0 in most cases. First impression are that the whites play is very aggresive and logical not that many hard to remebmer opening moves.

The book has only one drawback as far as I can see. After 2 Nc3 only d6 is covered. It always thought that Nc6 or e6 was the critical lines so one must complement with other books or discs to get a complete repertour. For fans of tricky opening I recommend this book.

Also about the name, I have seen, but no bought, a Chessbase 1h dvd about the opening by by  Lawrence Trent called "The Sicilian Gashimov Variation" and it is the same opening and from synposis it looks like the same variation and plan.

Sorry my mistake you are right it is 2 Nc3. I got consfused by 2 .. d6.
I will write a review at any rate.

At my local chess shop I saw an new book order it today.
I will write a review here next week.

The Carlsen Variation goes s 1.e4 c5 2.Nc3 d6 3.d4 cxd4 4.Qxd4 Nc6 5.Qd2 followed by b2-b3 and Bb2. 

The book is written from whites points of view by Carsten Hansen.

4 Qxd4 is not an new move, its usually called Chekhover Variation or sometimes Szily Variation or Hungarian Variation. While I play Qxd4 system I have always play Bb5 after Nc6 could be interesting to see the lines goes for an academic intesrest if nothing else.
