Short answer: no GM, IM whatever has looked beyond Spielman-Cohn. For other sidelines it is the same.

As a general comment about the Greco-complex. Most analysis are notoriouosly bad in the sidelines. English writers dont seem to know Estrin and even he often just cites a game from the prehistoric era in these sidelines. As in this case he just quotes Spielmann-Cohn. They dont even notice the transposition I mentioned and quote another oldie for that line. So it pays off to do your own homework. It certainly has netted me some extra points.

Yes and that's why I prefer Bg5 to d6

The normal move is 8...Bxc3.  Soltils writes that only two other moves have been tried here [in master practice].  One is the clever 8...0-0, based on regaining the piece via 9.Nxe4 d5.  However, 9.d5! is a simple refutation since to avoid dropping material Black must play something like 9...Bxc3 10.bxc3 Ne7 11.Re1 Nf6 12.d6! as in Spielmann-Cohn, Carlsbad, 1907.

Obviously 8...0-0 doesn't lose on the spot, and I guess it's playable.  Probably not Black's most ambitious try, though.

Thank you for your statement, but i prefer 8...0-0(!!), because this line is well unknown. But can anyone tell me, whats wrong with this line ? I analysed it with my computer and i can say, black must be carefully but its O.K. !

yk

Hello,

can anyone tell me something about this line ?

1.e4 e5
2.Nf3 Nc6
3.Bc4 Bc5
4.c3 Nf6
5.d4 exd4
6.cxd4 Bb4+
7.Nc3 Nxe4
8.0-0 0-0(!!)

I like to play this line with black and i am very succsessfully with it. But i have never found any documentation'bout this line. I checked the line with a computer and it tells me, that this line is O.K. for black, by correct playing.

What do you think about this line ?
