Composing GMs

Many Grandmasters composed chess problems, often those were endgame studies. You might think of Pal Benko, Jan Timman or John Nunn. But I was astonished to learn that also the Polgar sisters, Alexei Shirov and Alexander Morozevich have composed, though not as much as the first three I mentioned. Maybe, you like the following study by GM Salov, too.
