I don't understand

I don't understand

1. Kh1 Qh4
2. Qxf3

Why doesn't white play

2. gxf3

??

And after

1. Kh1 Qh4
2. Qxf3 Bxf3
3. Nd5 exd5
4. Re7 Rxe7
5. Kg1 Rxe1
6. a4 Qg5
7. cxd5

I don't understand

Rxf1+

why not

Qxg2#

Any hints welcome.

Per your first question, after

1. Kh1 Qh4
2. gxf3 Qg4

White cannot stave off mate, as there are too many threats.

Per your second, I don't know, but you're absolutely right.

Thank you rolg for disproving Gamknot chess computer "infallibility"

Your

1. Kh1 Qh4
2. Qxf3 Bxf3
3. Nd5 exd5
4. Re7 Rxe7
5. Kg1 Rxe1
6. a4 Qg5
7. cxd5 Qxg2#

is superior to the computer`s

1. Kh1 Qh4
2. Qxf3 Bxf3
3. Nd5 exd5
4. Re7 Rxe7
5. Kg1 Rxe1
6. a4 Qg5
7. cxd5 Rxf1+
8. Kxf1 Qc1#

I`ve sometimes suspected it`s "best play" analysis,but this is a blatant error.
