I saw this almost 40 years ago, and used to show it to everybody. Thanks for reminding me of it. I hope you're doing well.
Thanks Kuri, I hope you are doing well, too.
What fascinates me is that it takes only four pieces to create such a complex puzzle.
Really good,and and really have liked it.Hope you will post nices ones like that again.
Very nice. Solved everything after calculating except I hesitated for a few moments considering the stalemate trick. Very nice.
Ich bin nicht klug genug. Was für ein Rätsel! Vielen Dank. Ich wünsche Ihnen Frohe Weihnachten und einen guten Rutsch! Alles Gute. I wouldn't have been able to think this up, or solve it over a chessboard, if my life depended on it :) But it is indeed a thing of beauty! Thanks for sharing it.

Danke - ebenfalls Fröhliche Weihnachten und ein Gutes Neues Jahr! 
Don´t worry - if you don´t already know both thematic ideas (stalemate trick and double threat) it is really hard to solve that one at first go.
Nice! I've seen that puzzle many times.
Nice Puzzle!~
Saavedra position... Beautiful!
Woot! I solved it. Though I heistated after pawn promotion to rook.
Your Right
Maybe the most beautiful endgame puzzle I have ever encountered. Enjoy!
