still no pdf of the book's contents...I'm curious as to what may be behind the delay. I hope nothing too serious.

In the Kings Indian thread there has been a post about a new book by a new publishing company. I looked at the link and saw that the commisioning editor of the company is Anil Gupta and amongst the new titles is a repertoire book on the Petroff by GM Har-Zvi... due out in August/December 2014.

That's also a line worth mining for ideas. Black has an extra tempo, but that doesn't always make a difference if say in a QGA version, White plays h3 to be met by Bxf3, whilst in the French or Petroff version, Black can take on f3 immediately. It's what happens after 1. Qxf3 Nxd4 2. Qxb7 Nf5 that I'm exploring having had that in a recent game. Which Rook should go to d1 for instance hitting the Queen?

Most of the practical experience of the position is from the French move order and while I've won games from other move orders in the Exchange French, the Nc6 and Bg4 plan is particularly drawish. The Carlsen move order is interesting, because in practice the move .. Bg4 is a nuisance and he managed to rule it out by getting h3 and h6 played. The other difference from a more normal French derived position is that he's tempted the Bishop to d6. This can be important in tactical sequences since the d4 pawn isn't hanging. So Carlsen's play in the Petroff could reinforce White's play in the Exchange French.

An early c4 before moving the Bishop has the additional point in that cxd5 can be played

I know next to nothing about the QGA, so it would be great if you could give the whole line? How could a black pawn end up on d5 in the QGA? 1. d4 d5 2. c4 dxc4 3. e3 e5 4. Bxc4 exd4 5. exd4 Nf6 6. Nf3 Bd6 ... is this the line you are talking about? I don't see the similiarity ...

Or Cohen adresses this in "A vigorous chess opening repertoire for black" which is a Petrov repertoire book for black. His mainline is this game: 



He awards the move 7. c4 with "?!" saying that in his view this "loses any chance at an advantage".

Ain't the Yusupov variation looking like the Spassky "Tennis Court" variation (5.Qe2 Qe7 6.d3 etc) but with Black having somewhat easier game, since he was able to deploy his bishop to g7? It looks flat equal to me after 8...Qe7.

Black has no need to answer 6...d5 when white plays so slowly- both 6...Be7 and 6...g6 should be fine.
And anyway, I fail to find why playing some 3.e3 e5 queen's gambit accepted type of position where Black has not even captured on c4 yet (he can do it after white moves the f1 bishop) should worry Black at all.
