Philidor Defense

Initial Moves: 1.e4 e5 2.Nf3 d6

Strategic Summary & Main Idea

The Philidor Defense props up the e5 pawn with ...d6 and aims for a compact structure. Black accepts less space early on in order to prepare ...Nf6, ...Be7 and a later ...d5 break.

Typical Plans for White

  • Occupying the centre with d4 and developing with initiative
  • Exploiting the limited mobility of the c8 bishop
  • Gaining space without advancing further than necessary

Typical Plans for Black

  • Completing development with ...Nf6, ...Be7 and ...O-O
  • Preparing the freeing ...d5 break
  • Using the Hanham structure to keep e5 solid
