White now has a lead in development.
5... Qd8f6 6. Nc3d5
The idea to drive away the queen. However, 6. .. QxQf3 leads to doublec pawns.
6... Qf6xf3 7. gxf3 Ke8d8
This prevents the knight fork on c7, but removes the possibility of castling. Na6 is no alternative due to Bxa6 bxa6 Nxc7.

Opens up for the black squared bishop. Fianchetto on the queenside with b3 would allow a stronger attack on e5 (incl. d4, f4).

The movement of the bishop is now limited, so fianchettoing on b2 would have been a better plan.
9... f6 10. Bc1d2
Making space to castle.
10... Ng8e7 11. O-O-O
