How does black break into the position? What is a good plan for black? [fen ""]

1.e4 e6
2.Nf3 d5 
3.exd5 exd5 
4.d4 Bd6
5.Be2 Ne7
6.c3? O-O
7.O-O Ng6
8.Nbd2 Nf4
9.Re1 Nxe2+
10.Rxe2


Black's plan in the beginning was to take advantage of the (to-be) weak light squares around the white king by trading either his knight or light bishop for white's. It went easy, but now black can't find a solid way to break into the position.

Black sees that Qb3 is a potential threat that forks b7 and d5. The attack on d5 is not to be feared after 11. Qb3 b6 12. Qxd5?? Bxh2+, but this is how the game could have continued:

10... Bf5 (activating the light bishop and preventing white's control of the b1-h7 diagonal by Qc2) 

11. Qb3 b6
12. Kh1 c6


Does black have anything better?
This position is still very far from having a definitive character that would dictate the nature of best play. That is still perhaps twenty moves away. If you are already thinking that you have an advantage and just need to find a way in, you will not be playing objectively. Your position is fine, you will be able to develop easily, you have two Bishops, but you have no point of attack, and you don't know yet what White plans to do.

There is an old saying that if you can't think of a good move, wait until your opponent makes a bad one. I think that may apply here, because White has not yet played badly enough to lose, but it does not mean that you can just play anything. Do not simply play the position as it is. What can you create? There is usually something, which is how Magnus creates wins out of sterile positions.

I rather like ..b6 to be followed by ..Ba6, ..c5 and ..Nc6. That puts a lot of new ideas on the board, and gives White more chance to go wrong.
