I'm inclined to meet 6...Bd7 7.Qe2 Be7 8.Nf3 O-O with 9.Bxd7 Qxd7 & Deep Fritz 14 meets 10.Nxe5 with Qxd5 play continues 11.O-O Re8 12.Nf3 Bc5 13.Qd1 when White might have a slight plus, but has minimal winning chances.


I think 10...Qf5 is better: 11. d4 Nxd5 12. O-O c5 13. Nc3 Nxc3 14. bxc3 cxd4 15. cxd4 Bd6 is nearly equal according to Komodo. Of course, more analysis is needed.

Hi everybody,
I've been analyzing this line for some months, using the latest versions of Komodo and Stockfish, and got to the conclusion that black is totally equal.
I thought it would be interesting to share it with you and provoke a discussion.

The PGN file is a bit problematic because I created it with Aquarium, so I'm sorry about that.

When you see a square after the variation it's supposed to be "=+". And  -"square"+ is a decisive advantage for black.
When there is "[%t bShr]" before a sentence it means it should have been written before the move and not after it.

Last thing: of what I'm aware of, the analysis contained in the file is mostly original. Sorry if I'm wrong and someone has already done a similar analysis and published it before me.

I didn't manage to upload the file, and I haven't yet put as much time analysing it as the rest, but here is what I have found:

1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 Na5 6. Bb5+ Bd7 7. Qe2 Be7 8. Nf3 O-O 9. Nxe5 Bf5 10. O-O (10. d4 Qxd5 11. O-O Qxd4=) 10... Bxc2 11. Nc3 (11. d4 a6 12. Bd3 Bxd3 13. Qxd3 Nxd5=) 11... a6 12. Bc4 Nxc4 13. Qxc4 Re8 (13...Bd6 has been played before)
14. Nxf7 the critical test (14. d6 cxd6 15. Qxf7+ Kh8 16. Nf3 Qb6 17. d4 Bg6 with compensation; 14. d4 b5 15. Nxb5 axb5 16.Qxc2 Qxd5 with compensation) 14... b5 15.Nxd8 bxc4 16. Ne6 Bd6 17. b3 c6 18. bxc4 Bd3 19. c5 cxd5 20. Nxg7 Kxg7 21.
cxd6 d4 22. Na4 Bxf1 23. Kxf1 Rad8. Here Komodo says it's equal while Stockfish prefers white by a little bit. It might be a matter of taste and it probably needs further analysis, as with all the other lines here.

By the way, I think 8.Nf3 is the most critical.
