The Knights way.
By: User has deleted their account.
A knight can visit every place on the chess board ONCE without Doubling it's step.
*Edit: GOD you people don't get it. It's not like someone is going to cover all the squares during a game. It's just interesting to see that the L shaped patter of a Knight can cover all of the grid without Double stepping, REGARDLESS OF IT'S STARTING POSITION.
