Re: Chess
There seems to be a mate in one - nd3. So if you want to prolong the agony, just keep moving the king back and let that b pawn advance…
Oops, edit: playing in the wrong direction! Plainly nd3 and kxb. Sorry.
Nd3… kxb
Nd3-f2 ..pb6,
(If kg3, qg1 mate)
qh1 kg3
qh2 mate

Did someone say something?
Couple of things to bear in mind with these problems:
- It ain't chess as in a game, it's chess as in a diabolical problem space.
- there's a gotcha (preferably several) with any obvious solution or promising line.

From past experience of these, this doesn't feel right (doesn't use the rook) - so please point out why!

now what?
perhaps:
If this were chess there is a mate in 6 with the queen taking all the e,f, and g pawns ending on e3 mate.
1. Qa1 g5 (or b6)
2. Qxe5 b6
3. Ka6 b5
4. Qxg5 b4
5. Qxf4 b3
6. Qxe3 mate
Which suggests:
1. Qd8 g5 (or b6)
2. Rd7 b6
3. Rd2 p(e3)xR(d2)
4. Qd4 mate

Thank you! Not sure what all the "mate in six" preamble was about, but I like the solution.
I'll blame COVID (fifth day) this time!

It's how I would play this position in a real game, particularly if I had time trouble. When I wrote that I did not have the answer. The mate in 6 showed me how to use the queen and I stumbled into the mate in 4. Some people may be interested in the thought process rather than just the answer.

Re: Chess
The solution:
The prize goes to 9873210 for the correct solution:
1 Qd8! b6 or g5
2 Rd7! g5 or b6
3 Rd2! exd2
4 Qxb6 mate
I think the rook sacrifice is brilliant as it not only gives black a move, it also frees the diagonal from b3 to the king. This is a problem by Fritz Giegold.

There have been suggestions (by Eon Musk!) of some sort of signalling device up his bum, with a mate elsewhere on a computer anal(!)ysing the game and sending him which moves to play.

Sounds like something out of the pawn industry.
