Why move bishop first instead of queen in this puzzle? In this puzzle (white to move), the solution first moves the bishop (to pin the knight) and only then the queen. Why is it better to move the bishop first?

After Qa4 Black can reply ...Kf8 if you capture there's ...Qd7 (pinning your knight and regaining it later)
A continuation would be 1.Qa4 Kf8 2.Nxc6 Qd7 3.Bb5 a6 4.Nxe7 axb5
