Accidentally posted my last comment. It's incomplete. Whoever can delete it for me, delete it if they can.
Seems pretty easy this week. With 1. Qh8, Black is going to have to deal with the constant threat of Qh3++, and White's Bishop can't be taken as a result. So the continuation would probably go:
1. Qh8 Rg7+
2. Kf6
Black still has to deal with the constant threat of Qh3++, and now the only way to do that is to go down on material and lose his rook.
2. Kf6 Be7+
3. Kxg7
Black is now a rook down. The rest is just technique really:
3. Kxg7 exf4
4. Qh3+ Kg5
5. Qh6+ Kf5 (if Kg4, then 6. Qg6+ followed by Qxe4 taking the other Rook)
6. Qh5+ Ke6 (no Bg5 to block or else 7. g4+ losing the Bishop and the Pawn can't take En Passant because the Rook is pinning it)
7. Qf7+ Kd6
8. Qf5
The Black Rook now has 3 spaces it can move or else be captured. If it tries to push the Pawn, it'll just be followed by:
8. Qf5 e2
9. Qxe4 Bh4
10. Qxf4+.
So:
8. Re5 and Re6 are responded to with Qxf4 pinning the Rook or Qxf4+.
8. Rd4 and White will just Rxf4, and Black will eventually lose his Bishop or his Rook.
The rest of the moves are rather intuition at this point, so if anyone wants to ask a continuation, I'll give it to them.

You miss the fact that 1. Qh8 Rg7+
2. Kf6 allows 2... Rf7 which means black can draw by perpetual.

Nice!
Can you consider to place FEN in the upper puzzle that we can use with our chess software!
Thanks!
