The rules are easy; keep your knight going into a zigzag by staying on the 7th and the 5th rank, while it controls the dark squares. The king stays on the 6th rank, moving forward into the other corner of the board. The bishop is in charge of taking the light squares. Note: if you want to make a puzzle like this, the bishop and knight have to start at the same square.
