Hypermodern Chess philosophy is based on the concept that you do not have rush out and control the center at the start of games (the most basic and important staple of chess theory is that you must control the center). Playing Hypermodern openings is also a way of taking chess out of the books. Some examples of a Hypermodern openings are The Grünfeld or Solosky's Opening. These are openings for people with the ability to counter attack and are really only for people that know whats up, chess wise.
