A special move with the king known as castling is allowed only once per player, per game (see below). A rook moves any number of vacant squares horizontally or vertically. It also is moved when castling. A bishop moves any number of vacant squares diagonally. (Thus a bishop can move to only light or dark squares, not both.)
Castling is permitted only if neither the king nor the rook has previously moved; the squares between the king and the rook are vacant; and the king does not leave, cross over, or finish on a square attacked by an enemy piece. Castling is the only move in chess in which two pieces are moved at once. [3]
Arimaa does not allow threefold repetition of the same position with the same player to move. In Go, a player may not make a move which repeats the previous position, as would occur if a player were to immediately recapture a stone in a ko situation. Creating ko threats is an important strategic consideration in Go.

The capturing pawn moves to the square that the enemy pawn passed over, as if the enemy pawn had advanced only one square. The rule ensures that a pawn cannot use its two-square move to safely skip past an enemy pawn. Capturing en passant is permitted only on the turn immediately after the two-square advance; it cannot be done on a later turn. [4]
The relevant part of the FIDE laws of chess is quoted below: [4]. 9.3 The game is drawn, upon a correct claim by a player having the move, if: 9.3.1 he writes his move, which cannot be changed, on his scoresheet and declares to the arbiter his intention to make this move which will result in the last 50 moves by each player having been made without the movement of any pawn and without any ...
