White has a couple of ways to obtain a small edge in this opening line.
The most direct approach is 7. Qg4, aiming at the g7-pawn. If Black responds with 7… Nf6, White gets the initiative after 8. Qxg7 Rg8 9. Qh6 Nc6 10. Nc3 Rxg2 11. Qh3 Rg8 12. Bd2, followed by O-O-O. Defending the pawn with 7… Bf6 disturbs the coordination of Black pieces, and the position arising after 8. Qg3 Nc6 9. Nc3 Nge7 10. Bf4 is in White’s favor. The most common reply is 7… g6, where after the Queen retreat (8. Qe2), White is ready to meet Ng8-f6 with Bc1-h6, preventing Black from castling.
The other promising option for White is 7. O-O d6 8. c4 Nf6 9. Nc3, with longterm space advantage.
