Sicilian Defense: Old Sicilian
Overview
Sicilian Defense: Old Sicilian is a specific line in the Semi-Open Games family (ECO B30), 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. Nf3 Nc6, after 4 plies of opening development.
The line refines Sicilian Defense, which traces back to the root opening King's Pawn Game.
The line splits into 4 documented sub-systems: Sicilian Defense: Closed, Anti-Sveshnikov Variation, Sicilian Defense: Nyezhmetdinov-Rossolimo Attack, Sicilian Defense: Open, and others.
Below the direct variations, the full subtree contains 67 documented sub-variations.
