There is no "common piece placement" in any opening. It always takes two to tango.
In the Scandinavian, the c8 bishop is ideally placed at f5, but against some white setups this is a bad choice (or even losing outright), so ...Bg4 or even ...g6 should be played. d7 is not a forced square for the b8 knight, either.
Nobody mentionned the real reason many are annoyed by scandinavian :
the important thing is that black (your opponent) chooses the structure he wants, and u cannot avoid it.
So black brings u on his/her field, and u have to be ready because scandinavian can be straightforward, especially if white plays carelessly.
Moreover, most don't like to "lose" their beloved e pawn, while pushing it (and protecting it unless u like to play 1.Nc3) is just wrong...
I don't get it. The Scandinavian isn't annoying at all. It's much more difficult to get something against the french defense. The scandinavian is a good opening but many players who play this opening are bad because they just memorize the setup and after that they blunder pieces left and right.
It's obvious that you don't get it- at all.
The best book on the Scandinavian (by M. Wahls, K. Mueller and H. Langrock) is about plans and structures in all of his 370 pages, and does not present a single line of theory to memorize!
It's obvious that you can't read at all. I wasn't talking about theory. I was talking about the players who just memorize the general piece placement like in the london system. They don't really understand the opening. I'm not talking about GMs here. Both the Londonsystem and the scandinavian are decent openings.
