Philidor Defense
A fortress around e5
- Solid
The Philidor Defense begins 1.e4 e5 2.Nf3 d6, named after the 18th-century French chess master François-André Danican Philidor, who championed 2...d6 as a sturdier reply than the more common 2...Nc6 (the same move had already been suggested two centuries earlier, in 1561, by Ruy López de Segura as a response to Pedro Damiano's theories).

Defining move
2…d6! — defence with a pawn
The move that sets the Philidor apart from the usual 2…Nc6
Instead of defending e5 with a knight, Black defends it with a pawn. The knight stays free for more important tasks, and the position is compact. The price is passivity: the c8 bishop is shut in and Black has less space.
Tabiya
The Hanham position
A typical Philidor position: Black has a fortress of d6, c6 and e5 pawns and d7 and f6 knights. White presses on e5, but breaking the fortress is not easy. The position is closed, so play is unhurried: White regroups, Black waits for a good moment for …exd4 or …d5.
The centre
A closed fortressBlack has the d6–e5 chain and a c6 pawn. White has d4 and e4 and more space.

Famous games
The Opera Game (1858)The Philidor Defense begins 1.e4 e5 2.Nf3 d6, named after the 18th-century French chess master François-André Danican Philidor, who championed 2...d6 as a sturdier reply than the more common 2...Nc6 (the same move had already been suggested two centuries earlier, in 1561, by Ruy López de Segura as a response to Pedro Damiano's theories). Philidor's own plan centered on the pawn break ...f7-f5 to contest White's center, reflecting his broader and highly influential view — expressed in his 1749 treatise — that pawns are 'the soul of chess.' The defense solidly supports Black's e5 pawn while keeping the position compact, but its cautious, largely passive character has kept it out of favor at the top level, even as it has found a modest revival in fast time controls. Its most famous outing came in the 1858 'Opera Game' in Paris, where Paul Morphy demolished the Duke of Brunswick and Count Isouard after they departed from mainline theory with 3...Bg4, producing one of the most celebrated combinations in chess history.
