Pirc Defense
Overview
Pirc 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 is reached after 3 plies of play, with the move sequence 1. e4 d6 2. d4.
The line refines Pirc Defense, which traces back to the root opening King's Pawn Game.
The line splits into 3 documented sub-systems: King's Pawn Game: Maróczy Defense, Pirc Defense, Rat Defense: Antal Defense.
Below the direct variations, the full subtree contains 35 documented sub-variations.
