Overview

Sicilian Defense: Closed, Chameleon Variation 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.

Play reaches this position via 1. e4 c5 2. Nc3 Nc6 3. Nge2, after 5 plies of opening development.

The line refines Sicilian Defense: Closed, Traditional, which traces back to the root opening King's Pawn Game.
