Sicilian Defense: French Variation, Westerinen Attack
Overview
Sicilian Defense: French Variation, Westerinen Attack is a specific line in the Semi-Open Games family (ECO B40), 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 5 plies and takes 1. e4 c5 2. Nf3 e6 3. b3 to reach the canonical position.
The line refines Sicilian Defense: French Variation, which traces back to the root opening King's Pawn Game.
