	\problem{Knight's Move}

	To solve this problem you need not be a chess player. You need only know the way a knight moves on the chessboard: two squares in one direction and one square at right angles to the first direction. The diagram shows 16 black pawns on a board.

	Can a knight capture all 16 pawns in 16 moves?
