Portable 1750L Sixty Four Level Chess Computer (600-2444) Basic Chess Faxback Doc. # 32297 THE GAME BOARD Following international chess notation, the game board is made up of 8 vertical rows (columns) called files, and 8 horizontal rows called ranks. Each file (left to right) is designated by a file board light and a letter of the alphabet (A through H), and consists of 8 squares alternately colored silver and dark gray. Each rank (bottom to top) is designated by rank board light and a number (1 through 8), and consists of 8 squares alternately colored dark gray and silver. NOTE: The dark gray and silver squares on the game board are referred to as "black" and "white," respectively, throughout this manual. THE GAME PIECES Description There are 20 dark gray and 20 light gray pieces, 40 in all. Each color has these pieces: 1 KING 3 QUEENS 2 ROOKS 2 KNIGHTS 2 BISHOPS 10 PAWNS NOTES: The dark gray and light gray pieces are referred to as "black" and "white," respectively, throughout this manual. We have provided 2 extra queens and 2 extra pawns for each color. Setting Up To set a piece, press the piece's round peg into the square's hole. Here's how to set up the game board. Set the board in front of you so the buttons are facing you. Set up the white pieces on the side of the board closest to you this way: Place the rooks on A1 and H1 Place the knights on B1 and G1 Place the bishops on C1 and F1 Place one of the queens on D1 Place the king on E1 Place a pawn on each square A2 - H2 Set up the black pieces on the opposite side of the board this way: Place the rooks on A8 and H8 Place the knights on B8 and G8 Place the bishops on C8 and G8 Place one of the queens on D8 Place the king on E8 Place a pawn on each square A7 - H7 NOTE: The queen always begin on a square of her own color. MOVEMENT Each kind of piece moves in a different way. The rook can move any number of squares vertically or horizontally, but it cannot move past a square occupied by another piece. The knight moves in an L-shaped pattern. It moves 2 squares horizontally or vertically, then moves 1 additional square at a right angle from its first move. At the end of its move, the knight must land on a square of a different color than the one it started from. The knight can move through squares occupied by other pieces. The knight is the only piece that can "jump" another piece. The bishop can move any number of squares diagonally, but it cannot move past a square occupied by another piece. The queen can move any number of squares vertically, horizontally, or diagonally. (The queen's moves are a combination of the rook's and bishop's moves.) The queen cannot move past a square occupied by another piece. The king can move only 1 square vertically, horizontally, or diagonally. The pawn can move only 1 square directly forward, except when capturing another piece (see "Capturing", below). It captures a pieces by moving diagonally forward 1 square, except when capturing an passant (see "Capturing En Passant", below). When it moves from its original position, it can move 1 or 2 squares forward. On subsequent moves, it can only move 1 square. A pawn can be promoted to a piece of higher rank. See "Promoting a Pawn", below. GAME RULES Checkmate - The Object of the Game The object of the game is to position your pieces so your next move would capture the opponent's king, and your opponent cannot move, protect the king, or capture your piece. This is called checkmate. Check Check occurs when a player's piece directly threatens to capture the opponent's king, but the opponent can move he king, or another piece, to escape capture. Capturing To capture a piece, you move your piece into the square occupied by the piece you are capturing, except when capturing an opponent's pawn en passant (see "Capturing En Passant"). Remove the captured piece from the board. Capturing En Passant A pawn can capture an opponent's pawn which has just moved 2 squares from its original position. Here's an example of an passant capture. 1. The white pawn advances from E4 to E5. The black pawn is still in its original position (D7). 2. The black pawn advances from D7 to D5. 3. The white pawn advances to D6 (one square behind the black pawn's position). The black pawn is captured by the white pawn, even though the exact square it is on is not occupied by the black pawn. Promoting a Pawn When a pawn crosses the entire board, it can be promoted to a queen or another piece, even if the queen or other piece is still on the board. See "Pawn Promotion" under "Making Special Moves"). Castling Castling protects the king from a potential check or checkmate situation by hiding it behind a fortified position. You can castle if all of the following conditions exit: The king has not moved from his original position. The rook which you want to move by castling has not moved from its original position. The king is not placed in check on its current square, the square to which it is going, or the square it passes over. The square between the king and the rook are not occupied. In castling, the king moves 2 squares in the direction of either rook. The rook that is closest to the king after the king has moved now moves to the square right next to and on the other side of the king. Castling counts as 1 move. NOTE: In castling, the king always moves first, then the rook. Draw Games In a draw, neither opponent can win or lose without making an illegal move. There are three types of draws. Stalemate 50-move rule 3-times repetition. Draw by Stalemate: If the king cannot move anywhere without being placed in check (see "Illegal Moves"), the king is not in check, and no other piece on the board can move, the computer claims a draw by stalemate. NOTE: Your computer recognizes draws by stalemate (see "Stalemate/Draw Game"). Draw by the 50-Move Rule: If 50 consecutive moves are played in a game where neither side moves a pawn or captures a piece, you can claim a draw by the 50-move rule. NOTE: Your computer does not recognize draws by the 50-move rule. Draw by 3-Time Repetition: If a piece returns to the same location on the board three times, you can claim a draw by 3-time repetition. NOTE: Your computer only recognizes draws by 3-time repetition in a row. (LB/eb 04/26/96)
