Author of a modified chess study

[fkarger]

Sometimes I try to make studies a little bit harder in order to challenge modern chess engines.

Supposed I want to publish such a modified study.

What is the official/correct way of doing this?
What is the correct name or way of telling about the author of the study?

Hello Frank:

Sometimes I try to make studies a little bit harder in order to challenge modern chess engines.

Supposed I want to publish such a modified study.

What is the official/correct way of doing this?
What is the correct name or way of telling about the author of the study?

I do not know about an official or correct way. I recalled that I read something about a famous problem called Mitrofanov's deflection and a similar idea found by Farago years before Mitrofanov. The second study could had been composed without knowing about the first. Anyway:

A genius' bad luck.

[...]
The two studies cannot be compared.
But the fact is there: Farago found Qg5 first. What to make of that?
Herbstmann, with his novelty of the idea, the jury with its it doesn't look like any other, were mistaken. If they had known they might, unless Mitrofanov had humbly added: "After Farago", not have awarded the first prize to his study.

There is a proposal of 'after XXXXX'. I would say something like 'modified from XXXXX' or 'based on XXXXX' and being transparent, quoting the author and the original source (or a reprint if you do not know the original source) with the aim of track the original study and let clear to not present an idea as fully original. Last but not least, please remember that this is only an educated guess. Good luck!

Regards from Spain.

Thank you for your thoughts Ajedrecista!

I thought in the same direction.
It would be good to mention the modifified version.
