Pirc Defense
Overview
Pirc Defense is a specific line in the Semi-Open Games family (ECO B07), 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 6 plies and takes 1. e4 d6 2. d4 Nf6 3. Nc3 g6 to reach the canonical position.
The line refines Pirc Defense, which traces back to the root opening King's Pawn Game.
The line has 9 documented children — 150 Attack, 150 Attack, Sveshnikov-Jansa Attack, Austrian Attack, and others being widely played.
Together the deeper variations number 23 across the full subtree.
