In this variation, defending with 4. Bd3 is bad, as 4...bxc4 wins a pawn. Instead, 4. Nc3 is perfect because 4...b4 can be answered with 5. Qb3. 4. Nd2 is also an interesting option. The knight blocks the bishop, but his defensive potential is increased as both the c-pawn and the e-pawn are protected.
