Very challenging problem!

I just found the original source where I recalled the puzzle. It was from the book, "The Art of Defense in Chess" by Andrew Soltis. page 244, "At the Olympiad in Skopje in 1972 young Ljubomir Ljubojević of Yugoslavia took great delight in showing off the following position and challenging his grandmaster elders to find the one move for White that forced a draw:"

Apparently the problem was composed circa 1972. However, did Ljubomir Ljubojević originally compose the problem or did D. Djaja compose it?

Does anyone personally know either of these two chess players and can they ask them if they know who composed it?
Its famous! :D The good ones always are. Thx!

Your welcome.
Just remember next time not to use "my study".

p.s. He also didn't write Hamlet, Macbeth, The tempest and Romeo and Juliet.

:-)
I find it even more fascinating that the book where you found it was published first in 1975. This is pretty early for chess computers. They were just getting started! Crazy.
It's a clever idea, although the initial position is extremely artificial so I don't think in terms of beauty is anything special.
And sir, don't call other people's work "my work", I actually thought you composed a study (which would be very cool btw), there is no need to give credit if you don't know, but you can say "here is a study" ,not "here is MY study". This is so wrong in so many levels
And it is another thing if you create something that already existed and you didn't know, but lets be real, you never thought of this idea on your own
Ok, on second thought maybe I was a bit too harsh.
Maybe you were referring to "my study" as "my lichess study"
Still ,it was completely misleading, at least for me
#18 You are correct in assuming that I meant that "my study" is "My Lichess study". Sorry for the ambiguity which lead to the confusion. No copyright infringement intended. I gave full credit to the original author of the study.
