In his choice of universal systems against the c3 Sicilian and Rossolimo, I think he increases the demands of the repertoire. There are no special move-order specific shortcuts to decrease the workload. Also he does not shy from complexity. In many respects, obtaining complex positions is his aim, so he will not always appeal to those who favor simplicity. I think his approach has its logic, since many players of these systems with the white pieces tend to avoid theory, but it takes serious preparation and this is exactly what I would expect from Kotronias.

Bump!
Any further thoughts on this text?
My opinion thus far is that K is very much concerned with theoretical viability, likely with a heavy duty PC, but less so with what I might term 'usability', which is quite important for those of us who are not softwares. 
A number of the lines seem quite unfriendly.

I have been perusing the analysis at my leisure and generally like the recommendations - though I did notice that 1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Qxd4!? was not covered, which is sort of a bummer, since that's kind of a critical try.

Sorry, my mistake, wrong variation. The one I was thinking of was after 4. Bc4, not after 5. Bc4. The comment is in Experts on the Anti-Sicilian, btw.

I have it, it is excellent as all QC books are. I like most of the lines given. I would have like to have seen the Prins and 5.Bd3 in the Open as they are not covered in the QC Open Sicilian books on the Dragon or Sveshnikov.

But well worth getting, any more queries just ask
