How to study this family

White

White gets space and easy development, but must prove an advantage against Black’s sturdy pawn structure.

Black

Black supports ...d5 with ...c6, aiming for a sound center and a reliable route for the light-squared bishop.

Start with the shortest line, then branch to the variations that change the pawn structure or tactical target. Memorizing every branch before understanding the family plan is usually wasted work.
