Certainly it isn't mentioned in some books, though I noticed that Ruy Lopez Exchange by Panczyk and Ilczuk (circa 2005) had it ("7...c5? is bad due to 8. Nd5! when White has the upper hand [...]").


Interesting, I have that book but have become so accustomed to looking at games from the database and or getting assistance from my engine that I didn't even look it up.

Nice one indeed. It looks like White is close to winning in all lines, which is quite a rare find for a novelty on move 8! And a good example of how dangerous it can be to trust statistics of previous games.

I've been sitting on this innovation for about a year and finally got to play it today; my opponent hardly put up any resistance, but now at least it's not a novelty anymore: http://www.chess.com/livechess/game?id=480642771

Yandemirov, are you out there? http://www.365chess.com/search_result.php?search=1&m=9&n=3461&ms=e4.e5.Nf3.Nc6.B...

There are 28 games in chessbase featuring the following position after 7...c5, nineteen of them where White was over 2200, twenty-three where White is over 2000, and 8. Nde2 is played in every single one.


But isn't 8. Nd5! a bust to 7...c5?  If 8...cxd4?? obviously 9. Bf4, or if 8...Qd7  9. Nf5, so 8...Qd8 seems Black's best hope, but then White plays 9. Qh5 intending 10. Qe5(+) against any of the following:
  1. 9....cxd4
  2. 9....Ne7
  3. 9....Be7
  4. 9....Nf6

(or if 9...Bd6  10. Bg5)  Regarding the first of the above 9...cxd4  10. Qe5+ Kd7  11. Qxd4  Bd6  12. e5!  The last of the above may be best but after 9...Nf6  10. Qe5+ Kd7 White still is not forced to move away his Nd4 though 11. Nf5 or 11. Nb3 are worth considering, but rather he can continue to ignore the threat and play 11. Bf4 cxd4  12. Nxc7
