Chess

Chess is a classic board game of strategy and planning. Torn utilises two forms of chess, classic chess, and Chess 960 (also known as Fischer Chess).

Classic Chess

  • Starting positions are always the same.
  • The downside of classic chess is that players can memorize strategies, as well as easily utilize a computer program to help cheat.
  • Without cheating this game is more about memory than skill.

Chess 960

  • Chess 960 is a variant of chess invented by Bobby Fischer, it is named chess 960 because there are nine hundred-sixty possible starting positions. This form of chess generally utilizes more skill (as opposed to memorization which can greatly help in classic chess) than normal chess as there is no way to memorize early or even late game strategy.
  • This variant of chess also makes it very difficult for players to cheat with as they do not know the starting position of pieces beforehand to input into a program that could help them.
  • Torn features a unique rule forcing players to make their first move in a short amount of time to make it extra difficult to cheat.
  • This form of chess has a randomized start location for all pieces in the second row (behind the pawns), and a unique castling rule.

Rules

  • White always goes first.
  • Players will each start with one color (black or white).
  • You cannot move your king into check. (See Piece movement King for special rules)

Unique Chess 960 only Rules

  • Castling in Chess 960
    • Castling may only occur under the following conditions. The first two are identical to the standard chess castling rules. The third is an extension of the standard chess rule, which requires only that the squares between the king and castling rook must be vacant.
      • 1. Unmoved: The king and the castling rook must not have moved before in the game, including castling.
      • 2. Unattacked: No square between the king's initial and final squares (including the initial and final squares) may be under attack by any opposing piece.
      • 3. Unimpeded: All the squares between the king's initial and final squares (including the final square), and all of the squares between the rook's initial and final squares (including the final square), must be vacant except for the king and castling rook. An equivalent way of stating this is that the smallest back rank interval containing the king, the castling rook, and their destination squares contains no pieces other than the king and castling rook.
      • After castling, the rook and king's final positions are exactly the same as they would be in standard chess.

Piece Movement

White always moves first. After the initial move, the players alternately move one piece at a time (with the exception of castling, when two pieces are moved). Pieces are moved to either an unoccupied square or one occupied by an opponent's piece, which is captured and removed from play. With the sole exception of en passant, all pieces capture opponent's pieces by moving to the square that the opponent's piece occupies. A player may not make any move that would put or leave his king under attack. If the player to move has no legal moves, the game is over; it is either a checkmate—if the king is under attack—or a stalemate—if the king is not.

Pawn Movement

The pawn may move forward to the unoccupied square immediately in front of it on the same file; or on its first move it may advance two squares along the same file provided both squares are unoccupied; or it may move to a square occupied by an opponent's piece which is diagonally in front of it on an adjacent file, capturing that piece. The pawn has two special moves: the en passant capture and pawn promotion.

Rook Movement

The rook can move any number of squares along any rank or file, but may not leap over other pieces. Along with the king, the rook is involved during the king's castling move.

Bishop Movement

The bishop can move any number of squares diagonally, but may not leap over other pieces.

Knight Movement

The knight moves to any of the closest squares that are not on the same rank, file, or diagonal, thus the move forms an "L"-shape: two squares vertically and one square horizontally, or two squares horizontally and one square vertically. The knight is the only piece that can leap over other pieces.

Queen Movement

The queen combines the power of the rook and bishop and can move any number of squares along rank, file, or diagonal, but it may not leap over other pieces.

King Movement

The king moves one square in any direction. The king has also a special move which is called castling and involves also moving a rook.

Special Moves

Castling

  • Castling is a special move in the game of chess involving the king and either of the original rooks of the same color. It is the only move in chess in which a player moves two pieces at the same time. Castling consists of moving the king two squares towards a rook on the player's first rank, then moving the rook onto the square over which the king crossed. Castling can only be done if the king has never moved, the rook involved has never moved, the king is not in check, and the king does not cross over or end on a square in which it would be in check.

Promotion

  • In chess you have the ability to promote a pawn into a queen, knight, rook, or bishop by getting it to the other end of the board.
    • Promoting a pawn into a Queen is known as Queening
    • Promoting a pawn into anything else is known as underpromotion
      • Underpromotion can be effective in the case of a knight, as it can move in ways the queen cannot. Underpromoting to a bishop or rook has no benefits over the queen.

Check

  • When a king is under immediate attack by one or two of the opponent's pieces, it is said to be in check. A response to a check is a legal move if it results in a position where the king is no longer under direct attack (that is, not in check). This can involve capturing the checking piece; interposing a piece between the checking piece and the king (which is possible only if the attacking piece is a queen, rook, or bishop and there is a square between it and the king); or moving the king to a square where it is not under attack. Castling is not a permissible response to a check. The object of the game is to checkmate the opponent; this occurs when the opponent's king is in check, and there is no legal way to remove it from attack. It is illegal for a player to make a move that would put or leave his own king in check.

En passant

  • En passant is a special capture made immediately after a player moves a pawn two squares forward from its starting position, this must be done the turn after they move it. In order to utilize this move you must have a pawn 2 squares out, and to the side of them. When they do this you move your pawn behind them (single diagonal movement of 1 square), where they could have moved (1 spot forward) thus flanking them from behind and taking their pawn.
    • This is the only move in chess in which you can capture an opposing piece without landing on the square of the opposing piece (checkmating a king excluded).
