Well... you are either completely dumb, or you pretend being such pretty succesfully.
As I have previously explained, after 1.e4 f5? 2.ef5 Kf7? 3.Bc4+ Black can resign, already (two pawns down for less than nothing).
Houdini evaluation: +2.35, which hints at an, errr, small white advantage. Get it now, or not?
By sound, I mean can be played with success against any strength of player. An unsound opening can be exploited by a strong player to his or her insurmountable advantage.
In order to suggest that the opening is unsound, therefore, you need to be able to show where white could make a move that would "automatically" result in some insurmountable advantage. Neither Chessmaster nor Rybka, who on a fast computer are better players than you or I (or any other living person on earth) could find one. Indeed, I was able to draw Rybka at three different points, and asked Chessmaster for help only at 23 Nxg4 (it saw the sacrifice), which put the opening over the top and secured the win.
So, I ask you, where was the opening unsound? Where could white have done better? I was recently trounced by this opening, and must admit, I don't see a good defense against it. Playing it against the computer as white, I can't win from 5. Nf6. Black has too many ways to chase the queen around the board to ever recapture momentum. This is a very fast opening for black with lots of ways to keep the game under control.
