Yes, both.
What happened to the Evans Gambit?
I posted a great recent game in the Evans Gambit a few days ago in another topic.

It was just played in a tournament in the last week. One of Sonofpearls posts has a game where it's played. I don't remember which one but I remember it distinctly because you don't see it very often. Black won by the way.
At GM level, I guess that White will only enter the Evans if he's well booked up on it and thinks Black isn't, because if both know what they're doing, it won't be easy for White to show an advantage.
And if Black isn't ready to face the Evans, he will probably play 3..Nf6 entering the Two Knights, which gives Black good chances, rather than give White an opportunity to play the sharp Evans.

Its true GMs do seem to dictate the popularity of openings etc.
I think it is important to keep in mind though, as lesser-able players, that just because an opening doesnt give a GM a decent enough advantage over another GM, it doesn't mean that it can't give an advantage against the opponents we mortals encounter.
Personally, I see no problem in the Evans Gambit. White sac's a pawn for a lead in development. So far so good. But why has the Evans gambit grown out of favour? I've never seen it in any recent master games. Is it because the Italian game rarely occures in master games? Or is there a good strategy to counter it? Anyone?
