Chess 2: The Sequel create a more dynamic opening game, decrease the emphasis on openings memorization, and reduce draws. In "Chess 2", players may choose from six unique armies, such as an army with two kings and an army whose knights, bishops, and rooks may move like each other when adjacent. A new win condition has been added: a player wins if their king travels past the fourth rank. This was intended to prevent traditional "solved" chess endgames, which can be played by consulting a chess tablebase, and therefore does not require player skill. A third rule change from standard chess is the dueling
Chess with different armies rook replacement to c1. This is so colorbound pieces don't change square color. Many pieces in the following armies are combination of standard chess pieces and 4 fairy pieces: "ferz", "alfil", "wazir" and "dabbaba" (see their movement diagrams above). The game can be played with standard chess pieces and the following move diagrams use standard pieces as well (except queens). In this army, rooks, knights, bishops, and queen are replaced by the following pieces: As mentioned, when using this army and castling queenside, the king moves "three" squares (from e1 to b1) and the bede moves from a1 to c1.
