Semi-Slav Defense
Black supports the center with both neighboring pawns. The structure is strong but restricts the light-squared bishop; White chooses between a quiet buildup and developing the bishop before closing the diagonal.
Your plan as White
Decide whether to develop the c1 bishop actively or build a quieter center with e3.
The opponent’s plan
Use the c6–d5–e6 structure and prepare ...c5 or ...e5 when development permits.
Watch out: The c8 bishop can be restricted; do not open the center before your king is ready.
