White's two threats in this position are Qh5+ and Bxd7+. It doesn't really matter whether White plays
10. Bxd7+, or
10. Qh5+
first, unless she wants to leave out Qh5+ entirely and just save the a7-knight with 10.Bxd7 Qxd7 11.Nb5. But that plan has a terrible score for White, despite the two extra pawns, because of Black's bind on the d-file and easy development.
