i saw this somewhere :

my question is how is this called?

it is soo interesting in my opinion

and an awesome opening for white 

Damiano Defense.  White either mates or gets a lead in development.  For example, 3. Qe7 4. Nf3 Qxe4+ Be2 with an advantage to White.

Wins a pawn, loses his Knight!

I assume this is another joke?

this is not a joke and taking that knight would result in awesome positioning for white

thank you so much killabeez

@evil_homer wanna try a game where we start like this ?

Fine.  Here is the mate that will occur if Black takes the knight.

In fairness, I'd just take my Knight out to cover the centre earlier. :-)

Wow, very very interesting

I wouldn't move my king out.  Why not just move the pawn at g7 up and block the queen?  Ive had this done to me before and it really ends up with whites queen in jeopardy.

The same sequence takes place after 4..g7 

this happens with G7:

nice 1
