Play as black

The London System develops White’s dark-squared bishop outside its pawn chain, usually alongside d4 and Nf3. The Jobava London combines d4, Nc3, and Bf4, creating earlier pressure on the queenside. These Black sets use a supported central foothold and an active c-pawn challenge. Against the Jobava, an early a-pawn move limits the knight jump that can threaten a rook fork.
