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. $39
