If we ignore Hendrick and the black hog for a moment, we can see if it is possible for Katrun to catch the other hog. After a little experimentation, we find that the hog can always escape! We might think that the two people have to work together. If we ignore the hogs for a moment, we find that Hendrick and Katrun can never end up on the same square at the same time. How strange!

It is possible for each person to catch a hog without the help of the other person. A psychological trap built into the puzzle tends to keep us from finding the answer. It really is an easy solution.
