The game might transpose to the Closed Catalan with 4.g3 c6 5.Bg2 d5 6.O-O Be7 7.Qc2 O-O 8.b3 Nbd7. So the question is if White can do better, especially with 7.Nc3.
  

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.

It's clearly sound enough on all grounds: there's a very logical idea attached, it's ~+0.5 as per SF (along with a5 and a wide range of other moves!) and scoring just over 50% for black in ~100 database games if with a similar ELO performance difference to Bb7 and c5.

What it perhaps isn't is especially intuitive or QID like (for how some people play it anyway)

Avoiding the 4.g3 QID pawn sac line with 4…c6

I think one of the reasons (or the only reason?) why the QID seems to have almost disappeared from top level play is because of this dangerous pawn sac line that White has at his disposal:

1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.g3 Ba6 5.Qc2 c5 6.d5

I noticed that Anton Kovalyov has played 4…c6 a lot against 4.g3, presumably to avoid this pawn sac line but I don’t know for sure. Is 4.g3 c6 fully sound? Why wasn’t/isn’t it played more at the top level?
