About the Philidor Defense
After 1.e4 e5 2.Nf3, Black defends e5 with 2...d6. It is solid but a bit passive, because the f8 bishop is blocked.
Black keeps a strong e5 point with ...Nf6, ...Nbd7, ...Be7 and ...c6.
White plays d4 and gets more space; Black must not give up the centre too early.
Watch f7: Bc4 and Ng5 tricks are common against this setup.
