Strong Black Opening for Passive Player

Hello, everybody. I'm in need of an opening as black against e4 that works really well for somebody of my particular skillset. I'm not much of a risktaker and I often play for the endgame. Most of my problems arise when my opponents go for a middlegame attack and my position is too weak in order to stop it. This is the problem I had with the Pirc and sometimes even the Najdorf. Am I just playing these openings wrong or is there another opening system that will work better for me? 

Caro Kann

Sicilian Kan

If white decides to do 2. c3, I'd suggest 2...Nf6.

Against the Closed Sicilian, I usually aim for this kind of setup:

If you're not much of a risktaker, then I doubt that the Sicilian is the opening for you. 

Since you are not much of a risktaker, it's best if you don't start with pawn moves. For example, the Nimzowitsch Defense, which will eventually lead to many common openings you face. You can also play the French Defense which will make white face a very sharp position if not studied.

The London System as white. As black the 3...Qd8 Scandinavian against 1 e4, the Tarrasch Defense against 1 d4, the London System reversed against flank openings. The Tarrasch Defense might seem out of place in this repertoire but I believe it is a very practical choice because the black king does not come under attack and endgames are often reached (in my experience it seems I have a lot of 2 rooks each with many pawns each endgames). 

 You are making wrong questions and you are receiving answers that will not help you. There is no such a thing like a defensive opening choice that can guarantee to you the position you want to play.

 The Najdorf and the Pirc are both very solid defenses but you cant expect White's to play passively in order to achieve a playable position you like to play. Try to analyze your positional mistakes and why your position becomes weak and vulnerable to attacks. Is the problem that you missing tactics or you don't play some regular prophylactic moves? Perhaps your issue is that you don't understand when and how to counterattack....and that has nothing to do with the opening choice but with your general mentality understanding chess.

Once Bobby Fischer said: My ideas for chess changed when i understood that i can win with Black pieces.

 The evolution of getting better at chess is not the process of avoiding sharp positions but rather....pursue them. Conquer your fear and you will become stronger!

St. George 1...a6. 

A player I know with a similar style to you likes to play the Petroff and Old Indian defences.

I'm not very skilled, but I quite like the Indian Defences. They are very simple systems that result in passive games. The best part is that the King's and Old Indian defences can be transposed from the Pirc.

It would have to be the Berlin, Caro-Kann or Kan Sicilian, going for a hedgehog setup in the latter case.

With the Berlin, decline the Kings Gambit with 2...Bc5.

This has zero relevance.  He is asking about defending 1.e4, not 1.d4.

Petroff's Defense in also an excellent passive opening. You avoid more sharp lines than trying to reach the Berlin Defense.

The French Defense is very passive, but can lead to very closed positions.

You know absolutely nothing about the French if you think it is passive.
