With 6...Nc6, Black develops the queen's knight in front of the c-pawn and adds a second attacker on d4, alongside the fianchettoed bishop, with ...e5 as the intended follow-up. The most frequent answer, 7. d5, gains space and forces the knight to move again; 7. h3 instead keeps the center fixed and prevents ...Bg4, while 7. Be3 reinforces d4. Practical results are close to even, and engines give White a slight edge, with 7. d5 their top choice.
