d5: Meet them in the middle. You claim your half of the center right away and open a line for the light bishop.
c6: The Slav: defend d5 with a pawn that asks nothing of your pieces — and unlike the QGD, your light bishop is NOT locked in.
Nf6: Develop the knight and cover the middle squares. Wait to see what they are building before you commit.
