Rat Defense: Antal Defense
Overview
Rat Defense: Antal Defense 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.
It begins with 4 plies and takes 1. e4 d6 2. d4 Nd7 to reach the canonical position.
The line refines Pirc Defense, which traces back to the root opening King's Pawn Game.
