The Najdorf system in the Sicilian Defence has a legendary reputation as a defensive weapon for Black. It is an opening where people often strive for a full point, instead of simply defending the position with the black pieces. Many great players have contributed to the development of this complex opening. There were two world champions who formed much of their careers using the Najdorf system as their weapon of choice against 1.e4: Bobby Fischer and Garry Kasparov celebrated spectacular successes with it. Both players used the Najdorf (pronounced ny-dorff, rhyming with high-dwarf) during their child prodigy years and retained it as an important part of their repertoire during their entire careers
