Philidor Defense
Initial Moves: 1.e4 e5 2.Nf3 d6
Strategic Summary & Main Idea
The Philidor Defence protects e5 with the d-pawn instead of the knight: 2...d6 is solid, shuts in the f8 bishop and accepts passive play for a structure that is hard to break. The measured price is high for a defence to 1.e4 e5: the position after 2...d6 is +0.72, four times the +0.18 of 2...Nc6. The line that holds the defence together, the Hanham, measures +0.51 and is the lowest White evaluation; the attempts at active play cost more, and the Philidor Countergambit, with 3...f5, measures +1.56.
The pawn structure this opening produces
The Philidor structure is the most defensive of the open games. With pawns on e5 and d6, Black keeps a central strongpoint, but the f8 bishop sits behind its own chain and can only come out via e7, a passive square. White answers with d4, and from there two structures arise. In the first, Black exchanges with ...exd4: White's centre is left with a lone e4 pawn, Black gains e5 and a diagonal for a bishop on g7 or f6, and the game resembles a Sicilian with the c-file still closed. In the second, the Hanham, Black holds e5 with ...Nbd7, ...c6 and ...Be7, and the structure is closed and compact — the space belongs to White, and Black waits for ...b5 on the queenside or ...exd4 at the right moment. The common weak point is f7. With the c4 bishop aimed at it and the d7 knight away from f6, any deviation in move order leaves a knight jump to g5 or a capture on f7 working. That is why the Philidor punishes Black's haste more than White's.
Typical Plans for White
- Play d4 on move three and pose the question of the centre before Black completes ...Nbd7
- Against the Hanham, develop with Nc3, Bc4, O-O, Re1 and a4 and gain space without taking on e5
- Against 3...Nd7 4.Bc4 Be7?, take on e5 and win material with Qh5 or Qd5
- In the ...exd4 exchange, play Bf4 and Qd2 and castle long when Black's bishop goes to e7
- Against the Countergambit, take on e5 and go Ng5 followed by e6: the line measures +1.56
Typical Plans for Black
- Reach the Hanham by the right order: 3...Nf6 and only then ...Nbd7, so as not to open f7 on the way
- With ...c6 and ...b5, gain queenside space while White occupies the centre
- Exchange with ...exd4 and fianchetto with ...g6 when White castles short
- Do not pin with ...Bg4 before developing the kingside: Légal's Mate comes from that haste
- Avoid the Philidor Countergambit, which gives up the centre for an attack that does not arrive

Frequently asked questions
Is the Philidor Defence bad?
It is one of the highest White evaluations against 1.e4 e5: +0.72 after 2...d6. The main line, the Hanham, drops to +0.51, which is playable. The real cost is passivity: Black chooses a structure in which the space belongs to White and the f8 bishop has no good diagonal.
What is the right move order to reach the Hanham?
3...Nf6 4.Nc3 Nbd7, which measures +0.51 after full development. The 3...Nd7 order measures +0.89 and hides traps: 4.Bc4 Be7? loses material to 5.dxe5, and White can play Ng5 against f7 before Black covers the square.
Does the Philidor Countergambit work?
Not by the measurement. After 3.d4 f5 4.dxe5 fxe4 5.Ng5 d5 6.e6, the position is +1.56, the highest in the entry. The e6 pawn sits wedged in Black's camp, the light squares around Black's king are weak and the centre Black wanted never forms.
Common Mistakes & Where Most Amateurs Go Wrong
- 01 Developing with 4...Be7? in the ...Nd7 move order. After 5.dxe5 Nxe5 6.Nxe5 dxe5 7.Qh5, White's queen hits f7 and e5 at the same time, and Black loses material: +3.22, against +0.89 for 4...c6. The line:
1.e4 e5 2.Nf3 d6 3.d4 Nd7 4.Bc4 Be7 5.dxe5 Nxe5 6.Nxe5 dxe5 7.Qh5+3.22 - 02 Pinning with 3...Bg4 against 3.Bc4 and answering 4.Nc3 with 4...g6?. This is the Légal's Mate position: 5.Nxe5 gives up the queen, and if Black takes it with 5...Bxd1, 6.Bxf7+ Ke7 7.Nd5 is mate. Even before 5.Nxe5, the position is already +2.61. The line:
1.e4 e5 2.Nf3 d6 3.Bc4 Bg4 4.Nc3 g6+2.61
