description: In this quirky challenge, you move as the chess knight piece. Can you capture the enemy king?
objectives:
  - goal:
      - Robots can use the `move` command to move.
        But they only `turn` in cardinal directions.
      - You are special. You are a knight. 
      - Go forth and capture the King!
