    Hey TomTom, after your analysis it seems clear there are multiple options for black. The main idea for me was the use of the pressure on the Queen to force a good position or lose the Queen. This was the best I could come up with:




    and then Nf4 in response to Kh2, or Bxd5 if Kh1/Kg2

    I agree, I couldn't think of any other move nearly as good...
    I guess that 1st position was a bit too simple. This problem setting isn't easy 🙂

    Instead of Bd5 how about Bxc6?

    Then I guess the lines would then follow something like this:

    ...f3 then Kg3 and the queen has to give up the pawn and the king is on a journey to switch to the other side of the board if the need arises otherwise white can still either trade queens or attack blacks king.

    Now you're still a pawn up and white's kingside is still shaky. There is no immediate crushing attack, but if you play it calmly you should get there in the end.

    Mind you, I'd still manage to blow it.

    I think the key white defense is Ba4

    ...Nc2
    Bxc2 ...Rxd2
    Ba4 indirectly protecting the h1-a8 diagonal

    if ...Be4
    f3 stops that
