This opening is called the Caro-Kann defense. I would recommend checking out IM Andrew Martin's ChessBase DVD on it. After that, if you want ideas for white, start here: http://www.youtube.com/watch?v=ROwIrCn3D04

Thanks ! any idea for the continuation ? and the theories behind ?
Well, the main line (Capablanca Variation) looks something like this:
White's h5 pawn is a neat bit that can be a hindrance or a powerful thrust depending on how the game plays out. I tend to castle, bring my Bishop to e7, my Queen to c6 (as Black, of course) and slowly trade off material, but that's not the only thing. One reason why the Advance Variations and Panov-Botvinnik are popular is because White obtains a slight edge, but Black's position is so rock-solid that cracking it can be difficult, and a slip can lead to a lost endgame where Black garners the full point.
The Panov-Botvinnik resembles Queens' Pawn positions with the c4 pawn ready to be exchanged off, although play is a bit different. I recommend trying to find some works of Botvinnik himself dealing with isolani, as handling the IQP is important in this position. It's an open opening for the attacking player, and I essay it against the Caro-Kann fairly frequently!
Unfortunately, I'm not as familiar with the main line Advance Variation as I should be, given that I try to be a dedicated Caro-Kann player, at least over the board. However, I do know that 4.Nc3 begins some ridiculously complicated positions! I prefer 3...c5 against the Advance myself, as I'm familiar with the position and enjoy playing through it. Going to play some video games, though, so I can't expound just yet!
Sorry if that wasn't good, it was kind of a rush job. =(
