You don't have to be a good chess player to complete this week's task.
The riddle comes from my new book "Blind Date with Two Unknowns": A knight chases a king.
Both pieces move according to the usual rules of chess.
See the full description and amazing solution in the video below.
An addendum to the carpet puzzle from last week: The reader Bernhard Klaaßen has suggested a solution that works differently than the sawtooth cut described.
One can argue about whether it actually does the job, but it is definitely quite nifty, as you can read in the supplemented solution.
