The following matrix is noticable: Two other possible unifications, which hadnīt occured so far in playing chess, were carried out in CHESS 2000: knight/rook and knight/bishop. Their moves are similar to the ones of the queen as shown in the second diagram. The initial position for this chess variant is shown in the third diagram.
