Chess960 or FRC (Fischer Random Chess) is 960 starting positions of forced tactical thinking. Chess960 has a different dynamic to it that frightens many players who do not like to be challenged on an even playing ground. The advantages are that any player can take a strong position regardless of his or her strength or skill level for openings in traditional chess.
Memorization gives a player great advantage when recognizing openings. Chess960 levels that advantage. In Random Chess the power structure of the pieces is not evenly spread out from the center to the sides as it is in Traditional Chess, So you are forced to find a center and play a tactical game.
