Why are people annoyed by Scandinavian Defence?

I'm not annoyed. I destroy them with this line:

Well, I destroy them with this:

That's a good line. Sometimes my opponents play like this:

Nice! I have had good OTB results with it including a win over someone over rated 2200.

The system I posted at the top of this page. Works very well.

Another possibility is this variation:

This line is nothing. Black stands very well after 7...b5 8.Bb3 a5.

Short's 6.Qe2 is probably a bit more testing, but still not terribly annoying.

It was never about being annoying. You can play that against your IM friends but this doesn't change the fact that we play different chess at lower levels. You might play b5 but the typical braindead scandinavian player even at 1900 rating would never consider playing b5 that early. They always repeat the same moves over and again. Every non-master player would play the natural Bf5 and not some crazy pawn storm on the queen's side. While you might be objectively right about b5, you don't take into account that many people we play against will face this line for the first time and will play the natural scandinavian moves. It's about being practical.

For you for example it would make sense to learn the crazy lines of a najdorf sicilian but for us it doesn't make sense because even if we would understand every move we wouldn't be able to play them because our opponents deviate very early because they don't know the theory.

If you look at Magnus carlsen's games you can see that he doesn't play the typical London System braindead moves. He knows the subtleties of the position and is even willing to give up the "strong" lightsquared bishop on d3 for a knight on g6 just to secure the knight position on e5 (Carlsen - Tomashevsky Wijk Aan Zee, 2016). A normal braindead london system player will play typical moves like h3 and Bh2 without thinking. The positions are not bad but they are always the same.

If we know this we can't exploit the move orders they use and get an advantage. Unlike you who probably plays chess professionally or is a trainer we don't keep up with the newest theory or we just don't know what alternatives there are to the system moves. 

It's a different kind of chess at lower levels and that's why Bc4 followed by d3, Bd2 and Qe2 is so effective. I never encountered 7. ... b5 in my life so far and I play this line a lot. b5 is only played later in the game but not on the 7th move.

I agree. I'm more worried to play against the sicilian because the positions are more complex. After some inaccuracies black suffers a lot in the scandinavian. At our level players don't play the perfect chess where black finds one move and equalizes immediately.

My coach tells me as a GM that the Scandi can lead to a quiet game with lots of liquidation. You can play for something like a minority attack on the queen side, creating a weak pawn, and trying to win it. If you are good with pawn structure and endgames, it gives black a nice chance without lots of fireworks. 

I prefer Nf6 varition ( c4 is not good )

every opening is good

I like it, easy to beat

Thanks for these variations, they look interesting, I was looking for something to get the scandi players out of their comfort zone, I play with G3, it is nice as well, but I think they know it better, I will check this one out

I just do 2. e5!!

"black gets his queen kicked a lot"

if by a lot, you mean once, or twice with tempo loss, then you're right

I never quite knew how to play either side of it tbh. I always transposed into a different opening as white and never played it as black

"Why are people annoyed by Scandinavian Defence?"
 

Theoretically, it loses.

Practically, Black simply kick your a**, and he plays very obvious moves. I Always get his rook X-raying my queen... I'm no beginner:

Please cite the TCEC event where this shocking new refutation was discovered. Here's a list of openings used by the way. Good luck hunting!

I used to be annoyed by the Scandinavian, but after a little research I grew comfortable with the positions. Now I relish facing it as White, as I get good development and great active positions.
