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. Two world champions formed much of their careers using the Najdorf system as their weapon of choice against 1.e4: Bobby Fischer and Garry Kasparov. Both players celebrated spectacular successes with it, both used the Najdorf (pronounced “neigh-dorff”, rhyming with “high morph”) during their child prodigy years and retained it as an important part of their repertoire during their entire careers. For Garry Kasparov this added up to experience with the Najdorf at the very highest levels of chess.
