Why is Tal talking about 10. Qf7 when 10.... N5f6 is possible? I am picking from the book &quot;Attack with Mikhail Tal&quot; Chapter 1, pg 6. Tal annotates the steps and his thought process on the Tal-Larsen 1965 match.

1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. Nf3 dxe5 5. Nxe5 Nd7 6. Nxf7 Kxf7 7. Qh5+ Ke6 8. c4 N5f6

Tal continues with 9. d5+ Kd6 10 Qf7 Ne5. I am stuck on the Qf7. Why is Qf7 possible when there is 10... N5f6? What am I missing here?
Here is the original excerpt.
You made a mistake when transcribing move 7. It is 7. Qh5+, not 7. Qf3+. Move 10 is then Qh5f7, which is not blocked by the Nf6.
