Each kind of piece moves in a different way. ± «#/ ª (rook) -- can move any number of squares vertically or horizontally, but it cannot move through a square occupied by another piece. Basic Chess Instructions ¥#/ ¤ (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 even if the squares it moves through are occupied. (It is the only piece that can "jump" another piece.) ¡#/ (bishop) -- can move any number of squares diagonally, but it cannot move through a square occupied by another piece. 4 -#/ ¨ (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 through a square occupied by another piece. £#/ ¢ (king) -- can move only 1 square vertically, horizontally, or diagonally. Basic Chess Instructions §#/ ¦ (pawn) -- can move only 1 (or 2) squares directly forward, except when capturing another piece. It captures a piece by moving diagonally forward 1 square, except when capturing en passant. (See "Capturing En Passant" on Page 6). 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 higher-ranking piece. See "Promoting a Pawn" on Page 6. )#/'"47.'5 %JGEMOCVG"L"6JG"1DLGEV"QH"VJG")COG 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. 5 Here's an example of an en passant capture. The white pawn advances from E4 to E5. The black pawn is still in its original position (D7). %JGEM Check occurs when a player's piece directly threatens to capture the opponent's king, but the opponent can move the king, or another piece, to escape capture. %CRVWTKPI 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. The black pawn advances from D7 to D5. Basic Chess Instructions %CRVWTKPI"'P"2CUUCPV 'P"2CUUCPV A pawn can capture an opponent's pawn that has just moved 2 squares from its original position. Whenever your pawn is on your fifth rank, and your opponent moves 2 spaces to the same rank adjacent to your pawn, then you can declare en passant and move to your sixth rank immediately behind the pawn, then capture the pawn. 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 white pawn. 2TQOQVKPI"C"2CYP If your pawn advances to the eighth rank, you can promote it to a queen or another piece, even if the queen or other piece is still on the board. %CUVNKPI Castling protects the king from a potential check or checkmate situation by hiding it behind a fortified position or moving it out of immediate danger of attack. You can castle if: 6 · The king has not moved from his original position. · The rook that 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 a square it passes over. · The squares between the king and the rook are not occupied. If a rook is on the same side of the board as the king's square, this is called a king's side castle. If the rook is on the same side of the board as the queen's square, this is called a queen's side castle. 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. #"+/2146#06"# If the computer is thinking, it might not turn off when you press RATING/OFF.
