Slav Defence

It's the moves

1. d4 d5

2. c4 c6

So I've got some questions about the Slav. 2. …c6 seems very weak. It does nothing to develop a piece, control the center, grab the initiative , or anything else that comes to mind. Indeed, it blocks the knight from developing to c6, and it develops on the flank. If anything, it only provides a solid (passive too, but solid just the same) way of defending the d pawn. It's not like the d pawn is undefended, either, (although early development of the queen is undesirable) it seems to be a very weak, passive way of defending not the d pawn, but the theory that the queen should not be developed early. Why not 2. …Nf6 instead?

So could you explain me ( us ? ) what this opening is interesting for ?

Sorry if I make mistakes but English isn't my mother tongue.

Yes -Maximus- I like your idea of 2... Nf6

Thanks a lot !

The Slave is used to deal with QGD. Black faces three major problems in many variations of the QGD.

1.Developing of the black queen bishop is difficult, as it is often blocked by e6. 

2.The pawn structure offers white targets, especially the possiblity of a minority attack on the queenside in the Exhange variation of the QGD.

3.White often plays Bg5 to pin the black knight on f6 against the black queen, and unpinning it is awkward for black.

The Slav addresses all of these problems.

I have a good understanding of the Slav. I would love to learn more from here.
