Scandinavian Defense: 2. e5 ... white response" (Playing as Black)



2.e5 does nothing to contribute to white's development, or pressure Black.
2...Bf5 is comfortably equal, and 2...c5 probably a bit more than that.
Add to that a fact: the regular variations of the Scandinavian are either passive (2...Qxd5, 2...Nf6 3. d4 Nxd5), or risky, borderline unsound (2...Nf6 3.d4 Bg4?!, 2...Nf6 3.d4 e6?!).
But if you ask what to do after 2.e5?! and the first thing you consider is 3...f6, then you'd rather forget about opening moves, and concentrate on the basic elements of positional play- else you are just wasting your time trying to "learn" openings.
The thing about 2... Bf5 is you can look at it two ways. One is the French Defense but your Bishop is not bad anymore. The other is the Advance Variation of the Caro-Kann but you're up a tempo. It's simply a better version of the regular openings it resembles for Black. Maybe c5 is even better in that position, Idk. Maybe your "best scenerio" line is not bad either if White actually plays into it but without looking closely at it I see your backward e-pawn right away. This is why we don't play the Bologh Defense.
