king's pawn opening query

the program 'freechess'
http://www.freechess.net

plays this opening as black on 'hard' level:

1 e2-e4    e7-e5
2 Ng1-f3   Bf8-d6

....defending the e5 pawn with the bishop rather than the more common Nb8-c6 'epine dorsal'

I have checked the brilliant Network Of Chess Openings Site http://www.csm.astate.edu and it wasn't listed.

Have you come across it before and if so what are good responses for white ?

i wondered if it even had a name.

it is very surprising because one would normally expect chess software to stick to established book moves. it plays this opening every time though.

thanks for the advice too.

give it a whirl if you can. the program can be found here http://www.tucows.com/preview/239701

the programmer seems to think it's a fair opening for black even if the rest of the world thinks otherwise!

if it's possible, perhaps you can point out at which stage it becomes obvious it was a blunder for black.

2...Bd6 is not a blunder (it doesn't hang anything) ; it's simply a move that slightly hampers black's development.

I think all of Neneko's suggestions make sense ; I would however not play an immediate 3.d4 as 3...exd4 frees black's bishop diagonal and may give a justification to its position, but that's only my opinion. 

Well, with Bd6, the king's knight should avoid the f6 square otherwise white will attempt to pry open the center and fork the bishop and knight with a pawn on e5.

So if the knight moves to e7, things will start to look very cramped.
