Philidor Defense
Overview
Philidor Defense is a specific line in the Open Games family (ECO C41), arising from a recognised theoretical position.
The Open Games group covers open games — classical 1.e4 e5 openings where both sides contest the centre directly with pawns.
It begins with 5 plies and takes 1. e4 e5 2. Nf3 d6 3. Bc4 to reach the canonical position.
The line refines Philidor Defense, which traces back to the root opening King's Pawn Game.
The line splits into 2 documented sub-systems: Philidor Defense, Lopez Countergambit.
Together the deeper variations number 3 across the full subtree.
