About the French Defense
Black answers 1.e4 with 1...e6 and then ...d5, attacking White's centre. Black accepts a little less space for a very solid position.
If White plays e5, pawn chains form: White attacks on the kingside, Black on the queenside.
Black hits the chain at its base with ...c5 and adds pressure with ...Nc6 and ...Qb6.
The light-squared bishop on c8 is often passive; Black may trade it or free it with ...b6 and ...Ba6.
