The idea
Black plays both ...c6 and ...e6, combining Slav solidity with QGD structure. The downside is the light-squared bishop is temporarily blocked, but Black gets very reliable positions.
The plan
After the Semi-Slav structure is set up, Black aims for ...dxc4 and ...b5 to hold the pawn, or plays the solid ...Bd6 and ...O-O. The Meran and Moscow variations are key lines.
What to play next
After White plays Bg5, develop the knight to d7 to keep the e-file clear and pressure c5. The queen goes to a5 to pin the Bg5 and create queenside pressure. After White captures on d5, recapture with the knight to control e3. The resulting position leads to sharp Semi-Slav theory.

One tip for beginners
The Semi-Slav leads to some of the most complex chess theory (Botvinnik, Meran). Start with the simple ...Bd6 or ...Be7 developments before exploring the sharp lines.
What to watch out for
The Botvinnik Variation (after ...Nbd7 and Bg5 and e4) is extremely sharp. If you're a beginner, avoid it and play the calmer ...Nbd7 without allowing e4 immediately.
