Well Corus was interesting in that Short showed this dxe5 line is now his main weapon against the Petroff. Check out Short-Kramnik where Kramnik was "almost" lost, and the entertaining last round encounter Short-Smeets (where it looks like White needs an improvement against Smeets somewhat brave king advance.)

Caruana didnt play this line, he played the "normal" (now) 3.Nxe5 followed by 5.Nc3, 6.dxc3 line which we can almost classify as a main-line now due to its popularity. Its not a bad line but not to everybodys taste.

Caruana - Kramnik yesterday in Corus A looked solid for black. White never had something. Any comments to this game?

Possibly of some interest is that Kasparov played this line against the Petroff in his joint Simul with Carlesen the other day. The plan of Qxd2-f4-g3 is a bit crude, but it makes a change from the normal Petroff stuff:

[Event "Simul Marrakech"]
[Site "?"]
[Date "2010.01.14"]
[Round "?"]
[White "Kasparov, Garry"]
[Black "Morad, Cherigui"]
[Result "1-0"]
[ECO "C43"]
[PlyCount "59"]
[EventDate "2006.08.05"]

1. e4 e5 2. Nf3 Nf6 3. d4 Nxe4 4. dxe5 d5 5. Nbd2 Nxd2 6. Qxd2 c5 7. Qf4 a6 8.c3 Nc6 9. Bd3 Be7 10. Qg3 Kf8 11. O-O Be6 12. Ng5 Bxg5 13. Bxg5 Qd7 14. Rad1 d4 15. Be4 Bd5 16. Bb1 Re8 17. f4 Qe6 18. Rde1 Bc4 19. f5 Qc8 20. e6 f6 21. Bf4

Michael Goeller has a great article on the dxe5 lines at http://www.kenilworthchessclub.org/games/java/2008/petroff-d4.htm

He prefers a move order with 4.Bd3 first to avoid black's Bc5 idea. Note that this does allow the shocking 4...Nc6 which looks like a gross blunder if you haven't seen the idea before.


Interestingly Svidler used this order the other day to dispose of the old maestro Karpov, so it would seem well worth investigating - at least we´re not going down the main roads...

[Event "City of Culture GM"]

In Bacrot´s game the position after 15-20 moves looked very unbalanced. But does white have an advantage? Maybe giving up the d-file was wrong for black.

Interestingly both Gelfand and Jakovenko preferred 6... c5 with black recently and Jakovenko with white avoided 7.c4.  Cheesy

Your reasoning behind 6...h6 seems logical to me. If white tries 7.c4 now, black may well gambit the d-pawn with 7...Nc6 8.Qxd5 Bg4 since 9.Qxd8? Rxd8 10.Bf4? Bxf3 11.gf3 Lb4+ looks disastrous. Okay, weak play by white. Better than 7.c4 must be to continue development with  7.Bd3 or 7.Qf4.

At least this variation avoids the symmetrical pawnstructure so typical for many lines in the Petroff. A good thing in my view.

I´m not sure 6...c5 is the most accurate:

7.c4 and now after the natural 7...Be6 Bacrot won a nice game this year with 8.Ng5 which causes Black some discomfort.

The move I think for best for Black is 6...h6! to be followed by ...c5, as yet I´ve not found anything super convincing for White here.

After 6.Qxd2 the space grabbing 6... c5 as played by Jakovenko and Gelfand looks logical, since black seems to have a smooth developing plan with Nc6, Be7, Be6, queen somewhere and deciding about castling long or short. Looking superficially at the line it seems to be just another route to equality....for white!  Wink

The Petroff is a real pain for the e4-player. I´m glad I only had to face it in a handful of games in the last 20+ years.

Thank you for sharing the idea. I hope I remember it in my next encounter with the Petroff.

Having toyed with the idea of playing 1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nf3 Nxe4 5.Nc3 Nxc3 6.dxc3 - which seems to be the main way nowadays of escaping the heavily trod main lines, I just cant bring myself to play this line, its just not me.

I´ve turned now to 1.e4 e5 2.Nf3 Nf6 3.d4 Nxe4 4.dxe5!? which was the subject of a NIC yearbook article a good many years back, and seems a couple of GMs have given it a go this year also. I can´t believe 4...Bc5 can be sound after either 5.Bc4 or 5.Qd5, so 4...d5 5.Nbd2 Nxd2 6.Qxd2!? and the Queen will go to f4 with interesting play. The simple 6.Bxd2 also looks OK.

To be continued...
