Sicilian Defense: Closed
Overview
Sicilian Defense: Closed is a specific line in the Semi-Open Games family (ECO B23), arising from a recognised theoretical position.
The Semi-Open Games group covers semi-open games — replies to 1.e4 where Black declines the symmetrical 1…e5 in favour of an asymmetric pawn structure.
It begins with 4 plies and takes 1. e4 c5 2. Nc3 e6 to reach the canonical position.
The line refines Sicilian Defense: Closed, which traces back to the root opening King's Pawn Game.
It continues primarily into one named line, Sicilian Defense: Closed.
Together the deeper variations number 2 across the full subtree.
