Three Jog Knight


Harold Jacobs


The rock band Three Dog Night started to become popular in the late 60s. At that time, I created a puzzle to lead into a lesson in one of my math classes which I called the Three Jog Knight. Its purpose was to introduce some ideas about vectors; the puzzle was to show all of the ways in which a knight could be moved from the lower to the upper square in this chessboard in exactly three moves.
