There are brains and processors behind chess brains to produce a simple novelity in the 15th move of a variation of Grunfeld, or Najdorf Sicilian, Zaitsev variation on Ruy Lopez or even in the Owen´s Defense. Who do you think u r to censor me ? Did u even know how does it play a Paris Opening ?? Or Marshall counter-gambit ? So shut up u insignificant.
