The Closed Sicilian is an ideal weapon for players who wish for an aggressive way to attack the Sicilian but have neither the time nor the inclination to learn the mass of theory associated with Open Sicilians. In the Closed Sicilian an awareness of the typical themes is far more important than memorising variations. White's play is logical and the basic strategies are simple to master, while the deliberate and slow burning attack on the black king appeals to many.
