No reply to 1.e4 is played more. Fischer made the Najdorf his main weapon, and Kasparov's Sicilians are pillars of chess history — the Scheveningen against Karpov, the Dragon he unveiled against Anand in 1995. When you play 1...c5 you refuse symmetry, the same refusal that carried two world champions.
