Theres anything like london system for but for black?

Something you can play everygame...

edit:that title was dumb...

The Modern is probably the closest thing to a universal Black Defense. It shows up occaisionally in top level play. World Champion Magnus Carlsen played it recently, though he lost after saccing a Bishop for two pawns.

The Dark Knight System is interesting. It advocates playing Nc6 in reply to anything White does. It often leads to variations of The Pirc. It's offbeat, but not wildly so. The late GM Tony Miles used to play 1 ... Nc6 a lot.

There's also The Lion (aka. called The Black Lion), which is really sort of a Philidor, but interesting.

Thanks a lot! very useful

The london system is such that white makes solid moves to develop in a way that leaves him with no useless piece. White also takes no early risk with his pawn structure and makes sure he does not overextend.

Developing to leave your pieces usefull and not to have a bad structure is essentially the tenent of every black opening. So in a way the london is like playing a black opening with an extra move. The issuse with trying a system like this with black is that white is often going to set a very specific set of problems to black.

All that said I think the Caro Kann is stylistically similar in that the priority is to get the bad bishop outside the pawn chain.

While you can play system-like things with Black the middlegames usually aren't anywhere near as natural as the London system so be careful. 

Classical Slav, but you need something against 1. e4. I would say the Caro but this is really only true of the 3. Nc3/Nd2 lines, as the Advance and Panov lines are a bit different from Londons.
