No defense has won more games at every level than the Sicilian. Bobby Fischer played almost nothing else against 1.e4, and Kasparov's Najdorf battles with Karpov and Anand are pillars of chess history. When you play 1...c5, you're refusing symmetry — the same refusal that carried two world champions.
