[edit | edit source]

Most of the time in the Sicilian, White develops the knight on c3. White may yet play d4, leading to the Open Sicilian. White's move suggests the possibility of not playing d4, and instead playing a closed position. 3...d6 is the main line and is a non-committal move. Black retains flexibility to wait and see if White opens the game with d4 or keeps it closed with moves such as d3 and maybe c3 to prepare a d4 push.
