The only time a player may move the King more than a single space in one move, as well as move two pieces during the same turn, is during the issue of "castling". When "castling", the King (which must not have moved since the beginning of the game) is moved two spaces to either the King Bishop's initial hexagon ("castling King side") or to the Queen Knight's initial hexagon ("castling Queen side"). The involved Rook (which also must not have moved since the beginning of the game) is then moved "around the King" and placed next to the King. When "castling", the King is always moved first to indicate immediately the issue of castling, and the Rook is moved immediately thereafter to cement the legality of the King's "two-space" move.
The entire last (or "outer") rank, from the King's position to the involved Rook's position, is entirely clear of any pawns or pieces.
The King has not been moved since the start of the game, and the involved Rook has not been moved since the start of the game.
Both the involved Rook and King are safe from threat by any opponent pawns or pieces at the beginning of the castling procedure, at any point during the procedure, and immediately upon completion of the procedure (if any of the spaces on the last rank, between the King and the involved Rook, is subject to the actual force of an active opponent piece or pawn at any time during the procedure, castling cannot occur).
