Hmmm… I guess Rd2 for white should do the trick. Black may follow it up with …Qh1+ but very soon it will run out of checks, following which the black Queen won’t be able to protect the black knight for too long!

Unfortunately Rd2 does not work. 1 Qh1+ Kf2 2. Qg2+ followed by mate on e2 or g1 with Q.

I guess I am missing something here. After 1…Rd2 2.Qh1+ Kf2 3.Qg2+ Ke3, I can’t see how black can save its knight. Black can’t mate with …Qe2 because of the presence of white rook, and …Qg1+ by black leads to Kxf4 by white.

I was sloppy. Sorry. I saw Ke1 and saw that Qg1 was a mate and you are right Ke3 wins for white. The following is the correct refutation of Rd2.
1. Rd2 Qh1+ 2. Kf2 Nh3+
(2… Qg2+ 3. Ke1 (3. Ke3 white wins) 3… Qg1#)
(3. Ke2 Ng5 is ok for black)
3… Ng5 is also ok for black

Hmmm… Rd2 for white isn’t good at all. I see a more immediate forcing sequence (which I should have noted earlier) starting with 1.Nf6+… If 1…Rxf6, then there are all sorts of back-rank threats, e.g. 2.Rd8+… Other defensive moves by black also seem like losing ones.

Yes! There is a forced mate.
1. Nxf6+ Kg7
(1… Rxf6 2. Rd8+ Kf7 3. Qd7+ Kg6 4. Rg8+ Kh5 5. Qg4#
And this is what happened in the actual game!)
(1… Kh8 2. Qh7#)
(1… Kf7 2. Rd7#)
2. Rd7+ Rf7 3. Qh7+ Kxf6 4. Rxf7+ Ke5 5. Qf5+ Kd6 6. Qd7+ Ke5 7. Rf5#
