In that Chernov-Buhmann game 16.Be3 looks promising for white which could explain why Buhmann switched to h5 instead of Be7 in later games.

Anyway, the fact that no top player plays this line means that there is something suspicious about it...

Very nice! since White plays 7.a4 to kill the game anyway, that closes one more door for Black. Thanks a lot.

Strange, I also play this variation and have never faced 7. ... Nxe5 (it's usually ...Nbd4 or ...d6 or ...Nd6).

The Rio variation (5. Re1) is also an easy to play alternative, but could easily lead to a draw.

Hi. I sometimes play the 7.a4 line but never met 7...Nxe5 8.Nxe5 Nd6.  A couple of questions :
1. what about 9.Re1 Be7 10.Bg5 Nf5 11.Nxf7? White can recover his piece for sure, but I suspect this move is just rubbish. Perhaps this can be easily sorted out with today's computers ?
2. the idea 9.Qg4 Be7! 10.Qxg7 looks unpromising for White, but perhaps 9.Nc3 Be7 10.Qg4 is a better try ? After all, White has to make the d6 knight work for him.
Thanks for any light on the matter,
zoo.


11.Nf7 is White's best move, settling for a draw after 11...Kf7 12.Be7 Ne7 13.Qf3 Kg6 14.Qg3 Kf7 15.Qf3. Playing for a win is not recommended: 14.Nc3? Nf5! 15.Nd5 d6 16.Nf4 Kf7 17.Nd5 h5 18.Re7 Qe7 19.Ne7 Ke7 20.Re1 Kd8 and Black is better.

An important idea, since it means that White can play 7.a4 knowing that he has a draw in the bag after 7...Ne5  if he wants it.

9.Qg4 Be7 10.Qg7 Bf6 11.Qg3 is better for White according to Firebird, but Matamoros indicates that after 9...h5 10.Qh3 Ne4! 11.Qf5 Qe7! as played in Recuero Guerra-Lopez Salgado, Padron 2008, Black has absolutely no problems. White can also try 10.Qe2 as in Huerga Leache-Recuero Guerra, Pamplona 2008, but then 10...Be7 11.Rd1 Nf5 12.Nc3 d6 13.b3 0-0!? is promising for Black.

This 6.de5 variation is interesting, but objectively after 7...Ne5 8.Ne5 Nd6 White has no advantage whatsoever.
