Thank you for your first contribution on this forum!
The first puzzle (in the first post) is up to standards . A clear objective, no «duals», no overlooked lines, and Black always plays one of his best moves.
It seems like you understood this, since Black's response on his last move here is specifically set so there is a unique move from White to deliver mate in one afterwards. There would have been duals in other variations.
The first puzzle is an example of what people like to see on this forum.
