You can play c6 d5 against any opening
Thanks. I have been doing just that, just thought I had better double check before I spend a few more thousand hours on a false path. I like its simple (know it is far from simple in reality) set up. Though I have had a fair few games where it seems to take an age getting my King castled.
When the Slav is detailed in books it seems to be depicted as vs Queens Gambit, say my opponent plays D4 but slips into say London system or Colle, is the Slav carry on-able or do I need to look up something else. (does it have a name?)
I have decided to focus all my efforts on Caro-Kann and Slav as they have similar structures and seem to suit me.
Thanks for any insights. I know I am low and my focus should be on tactics (and it is in the main), I have just been trying things out lately to see how I like the lay of the land and Slav/Caro I am finding fascinating.
