Do you think that playing Chess 960 will help your regular game, hurt it, or have no effect?

It will definitely help because right now I'm way too reliant on my opening systems. Basically, it will help m strenghten my middlegame up quite a bit without actually having to go through the tedious work of learning a whole new set of openings to avoid getting swept off the board.

Playing Chess960 will help because you will reach endgames just the same as standard chess.  Developing your endgame skill is the best way to improve.  Playing Chess960 will allow you to work on endgames without worrying about reams of theory.

it probably wouldn't hurt though your openings might get rusty if you played it exculsively.
