Overview

Sicilian Defense: Closed, Portland Attack 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.

The line arises from 7 plies — specifically the moves 1. e4 c5 2. Nc3 Nc6 3. d3 g6 4. g4.

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