Sicilian Defense: Closed
Overview
Sicilian Defense: Closed is a named branch in the Semi-Open Games group of chess theory, classified under ECO B25.
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.
The line arises from 10 plies — specifically the moves 1. e4 c5 2. Nc3 Nc6 3. g3 g6 4. Bg2 Bg7 5. d3 d6.
In the opening tree, this line branches off from Sicilian Defense: Closed, part of the broader King's Pawn Game system.

Together the deeper variations number 5 across the full subtree.
