Just ask yourself : what is the main point of c6 in slav? To strenghten d5.
Considering white doesn't play c4 in London (usually), there is not point playing c6.
It also depends on how u play the slav as black...
Is the Slav any good against the London system?
Sort:
I really like it against the QGD I was wondering if it can be played against the London is it any good against it? Or Is it only the Slav only against the QGD? If played against the London does it become something else?
Thanks for your thoughts.
