Clemenz Opening[edit]


The Clemenz opening is a waiting move that gives black white's opening position. The goal of the Clemenz opening is to defend from moves that previously could have been made such as Bb4 or Nb4. In the Sicilian defense, the Najdorf variation has already been played after Nxd4 giving White (who theoretically is Black) an extra tempo. If it is true that black and white have an equal chance of winning, then making White into black with h3 should give white an advantage
