An interesting idea at this years Olympiad. Above the urinals in the (by necessity) Mens toilet, there are posted some chess problems (inside little frames which I suspect are normally used for advertising posters). I guess the idea is to give you something to do, while you have something else to do. The diagrammed position is one of the puzzles. I do not know who composed it, so I will refer it as Urinal Puzzle, 3rd trough from the left. It is White to play and Mate in 11.
