Same chessmen?
King in a corner with one friendly rook on the board?
Such constructions with a queen instead of rook are much more common.
Given enough information, we can probably find such things with a CQL query, or even SQL.
If I understood what exactly you were after, I think I could have been more helpful.
Without mechanical help from the computer and without a detailed description, it is unlikely for me to dredge such things up from my brain.
Any compositions like this?

Re: Any compositions like this?
Are you quite sure about this one?
I have my doubts again, seems to me, that Black can escape.
Could you give your winning line, please?
Peter.

Ottó Titusz Bláthy seems to have been very fond of that format.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Any compositions like this?
Two chessmen bravely face 16.
Sorted by lowest score to highest.
Some of the draws are probably wrong.

Re: Any compositions like this?
The second link is a song by Helen Reddy called "You and me against the world."
The first link is an EPD file named "youi-and-me-against-the-world.epd"
I guess that two chessmen facing the whole opposing army of 16 is an example of "you and me against the world"
But what do I know.
