Damiano defence.

Yep, Damiano's Defence. Best for white I think is 3.Nxe5 after which 3...fxe5 is met by 4.Qh5+

Thanks guys! 

That would allow 4...Qxh4

Once my friend played Nxe5 and lost! It is very surprising on how someone can lose as white in that move.

Maybe this would work for me otb.. if I study all the lines good enough as black!

I was looking at the live games from the world open in philadelphia recently & a GM actually played this opening as black. I cant remember whites rating but this was the open section & anyone can play up of course. Black won. 

But of course there's a whole range of reasons it's positionally faulty in my meager opinion. Weakened light squares, doesn't help development, takes good square away from knight, doesn't pressure center in any way, weakens K position, etc. If black wants to solidify his strongpoint there are a multitude of ways that don't have as many positional consessions. Just my humble opinion. Are there some IM's or GM's here that can shed positional/strategical light on this matter? I'm curious now. The GM that played it clearly done it as shock value (get opponent away from prepared opening) & I'm sure wouldn't have done it against stronger opposition. 

Pfren, do you think the positional analysis made sense or are there other positional/strategic points that are missing or make more sense? 

There's a very interesting video, on youtube.com, uploaded and commented by Mato Jelic : Bobby Fischer vs McGregor (simultaneous exhibition), when McGregor employs the Damiano Defense and "comes to draw"!

3...fxe5 is presumably not part of the Defence!

lately its been used as a gambit and not a defense so he probably lost to the gambit side of it.

Well it would be an illegal move, so that should take precedence :P Post fixed!

I believe that opening also has a nickname: it's called "what tha...?!"
