Back in the 1980s, the chess column of the German newspaper Heilbronner Stimme featured a special chess problem at the end of each year. Often it was a tricky moremover and an exceptionally tough nut - at least in my point of view. I vaguely remember that there were some puzzles with the staircase theme like the following. Maybe it was among them, maybe not. Here are many more problems with that theme.
