Overview

Rat Defense: Petruccioli Attack is a specific line in the Semi-Open Games family (ECO B00), 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 d6 2. h4, after 3 plies of opening development.

The line refines Pirc Defense, which traces back to the root opening King's Pawn Game.
