Chess

ELEMENTS
In a game of chess there are two opponents taking turns making moves; one using white pieces, one using black pieces. White always moves first to begin the game. Each player has six different kinds of chessmen: one queen, one king, two rooks, two bishops, two knights and eight pawns. The chessboard consists of sixty-four squares - eight horizontal rows (ranks) and eight vertical rows (files). Facing the board a white square is always at the lower, right corner. Set the white pieces on the board, from left to right on the first row as follows: rook, knight, bishop, queen, king, bishop, knight and rook. Set the eight pawns across the second row. Set the black pieces, from left to right, facing the player, on the first row as follows: rook, knight, bishop, king, queen, bishop, knight and rook. The two kings and two queens should be facing each other on the vertical rows. Set the eight pawns across the second row.

MOVE
Each of the chessmen has a different way of moving.
King: can move on square in any direction - vertically, horizontally and diagonally. The king can capture any opposing chessman on an adjacent square and remove it.

Queen: can move, like the king, in any direction but with an important difference. The queen can keep on moving until she is blocked by some obstacle to her progress, such as a friendly or an opposing chessman. The queen captures by landing on the opponent's square and removing the captured pieces.

Rook: can move vertically or horizontally, one direction at a time until blocked by the presence of a friendly or an opposing chessman. The rook captures by landing on the opponent's square and removing the opposing chessman from the board.

Bishop: can move only diagonally, one direction at a time. The bishop captures by removing the opposing piece from the board.

Knight: can move - 1) one square forward or backward; then two squares to the right or left; or 2) one square to the right or left; then two squares forward or backward. The knight can leap over the chessman on its way to its third square and captures and removes only on the end-square of its move. The knight cannot capture any chessman that it leaps over.

Pawn: can move only in one direction to the square straight ahead unless the square is occupied by a friendly or hostile man. Each pawn only on its first move, has the choice of advancing one square or two squares. A pawn may capture any hostile piece only if it is in front of it to the left or right diagonally.
