Collie as black?

What opening is similiar to the collie system that I play when I am white, that i can use as black?  Thanks in advance

You may be thinking pawn structure wise unknowingly. I will say a Slav structure as black.

As long as you don't do it as white, all is fine...

O Rly?

I thought the colle was characterized by the c3, d4, e3 structure.  Here white is doing the more active colle-zukertort.

Yeah but the dark-squared bishop didn't have to do much anyway heh.

From a pawn structure point of view, the Colle is basically a Reversed Slav  setup (the Slav typically being characterized by black forming the c6,d5,e6 light square pawn triangle. Black's main pawn breaks are ...e5 and ...c5, after due preparation).

Typically white develops pretty standardly in a Colle and hopes to avoid any real confrontations with black until he's adequately developed: d4,Nf3,e3,Bd3,c3,Nbd2,O-O,Re1,Qc2 (not necessarily in that move order) and then hopefully playing e4 and initiating some attacking possibilities on black's king side.

Also, it's worth noting that the London system and Torre Attack are basically the same as a Colle, sans the placement of white's dark square bishop. In the London, it goes to f4, usually on move 3. In the Torre Attack, it goes to g5 (assuming black develops his king's knight to f6, and he almost always does). In the Colle, white saves a tempo by not developing it at all. However, unlike the other two systems, there's no guarantee that the dark square bishop will have any prospects of an active future.
