ECO code: B07
Lion Defense: Anti-Philidor arises after the moves 1. e4 d6 2. d4 Nf6 3. Nc3 Nbd7 4. f4.
This opening is a variation of the Philidor Defense, where Black adopts a flexible but somewhat passive setup with ...d6 and ...Nbd7, aiming to support the center and prepare counterplay. White’s fourth move, f4, is characteristic here—it signals an aggressive intent to gain spatial control and launch a strong pawn center with e4 and f4.
From White’s perspective, this setup is clearly attacking, as White seeks to dominate the center and initiate kingside activity. Black’s position, while solid and somewhat defensive, is prepared to counterattack once White commits to the center.
The opening directly attacks the center, with White establishing a strong pawn presence on e4 and f4, aiming to challenge Black’s control and restrict Black’s piece mobility.
