After

1. Kg3 Qg1+
2. Kh3 Qxh2+
3. Qxh2 Qxh4 is not possible. In case you mean Qxa4, then
4. Qg2 Rd8 -> What now?

Interesting is also:

1. Kg3 Qg1+
2. Kh3 Qxh2+
3. Qxh2 Qa3 -> What now?

After

1. Kg3 h6
2. Qxa8+ Kh7
3. g6+ Qxg6+
4. Nxg6 Qg1+ -> What now?

The last sequence (1. Kg3 h5) is accepted, but please check your notation again (4. Kg3 is not possible).

By the way, just as a hint: chess software is not allowed to solve my problems (apart from some exceptions where I explicitly inform the competitors). I am sure you are aware of that, are you? :-)
I mention that because your variations are very accurate without any small typical human errors ... I didn't say you are using chess software - just wanted to state the rules again, just in case ... :)

Edit: Sleeping time for me: I will check all remaining answers tomorrow. Good night for now. :)

1. Apologies for the notation, with so many letters it's easy to get wrong
2. I know that chess software are not allowed, I think moves are forced in most cases, anyway, I present you my chess software :)

• 4.. Qg2 Rd8 -> What now?
  5.. Rxd4!! This move took me a long time to see it
  If Rxd4, Qa8#
  If Qxd4, a8=Q winning the game.

• 3.. Qxh2 Qa3 -> What now?
  4.. Qg2 (attacking the Rook again) Rd8
  5.. a8=Q Qd6
  6.. Bb2+ Kh8
  7.. Nf7+ Kg7
  8.. Nxd6+ Kh8
  9.. Qd8#

• 4.. Nxg6 Qg1+ -> What now?
  5.. Qg2 Qe1+
  6.. Kh3 Bxa7
  7.. Rf8!!

I'm very sorry if I made you doubt. Chess is my favorite sport and I always try to do my best.

Don't worry! I had to ask that. It seems you are very talented & engaged solving my chess problems. :)
I will put an official solution now with a few selected variations.
I hope you had solving this chess riddle which cost me quite some time to compose. :)
