Chess Tourist

When a chess piece has traveled around a chessboard touching every square exactly once, it has complted a "tour" of the board. Your task is to complete a tour on the board below using the selected chess piece. Your tour has been started on a randomly selected square. Green squares indicate a legal move, and the numbers on each square tell you how many open moves are available from that square. The "Warnsdorff" heuristic for finding a tour is to always move to a square with the lowest number of available moves.
