Queen H1 to F1?

Edit: I’m still an idiot.
- Pg2
  
  Edit: Apparently I'm being downvoted by somebody who doesn't understand white starts on row 1
  
  Qd3 Pg3 Qf5
- That's what I would have thought, leaves the King nowhere to go and there's nothing to block/capture the Queen.
  
  Black is moving down, Pg2
  
  Pawn to G2?
Bc6 Rb1+

Ke2 Rxh1

3.Bg2+ Kxg2

4.Nf4+ Kg1

5.Ke1 G2

6.Ne2#

Edit K for knight to N
- It appears I'm an idiot too
  
  I'm very new to chess annotation and i keep using k for knight and king.
- I think it's meant to be Ke1 G2 as Ne1 is an illegal move but that's just a notation issue
  
  Yeah it was very late i was meant to be asleep not playing chess puzzles knight starts with a k haha
- It seems to be open ended if black doesn't take queen, though
  
  Bishop moves to g2 checkmate of it doesn't check the king.
  
  If it does then the king walks back towards the rook. Until it takes it or the rook doesn't check the king ending the game
  
  What's interesting is if black moves to Rf4 and ignores the queen i see how it gets very open ended
- Nicely done! You solved the main (study) line. There's other lines where Black actually holds out longer, but they're much simpler to calculate.
  
  What happens if black declines the queen? Too lazy to calculate it out at this point
- After 4. Nf4+, wouldn't it be better for the king to go to f3? Or am I overlooking something obvious
  
  Edit: answered my own question, white king covers f3 after moving to e2, forgot about that
I need the reddit bot to try it online.
- My bad, next time I'll provide a link right away. Here you go: https://lichess.org/analysis/4B3/8/6N1/5p2/1r4p1/6pk/7b/4K2Q_w_-_-_0_1?color=white
  
  Thanks
King E1 to F1
- No that's no good either, then castle comes to check
  
  Hang on im still onto it.
  
  New plan
  
  Bc6
  
  Rb1 checking king
  
  Kd2
  
  Rb2 checking King
  
  Kc1
  
  Rook must leave or be taken. Anywhere doesnt matter.
  
  Qg2 checkmate
Does it involve Ke2, Pg2, Qe1? Ending with Qc1, Qh6

Edit nvm I'm dumb
- Unfortunately no. After 1. Ke2 g2 2. Qe1 Black has a simple way to win the queen, and after 2. Qc1 Black can at at the very least promote the pawn and there will never be a checkmate for White.
Qf1
