French Defense
The French Defense arises after 1.e4 e6, preparing to challenge White's center with ...d5. Black accepts a slightly cramped position in exchange for a solid pawn structure and clear counterplay. The French is known for strategic richness — Black typically has queenside counterplay while White attacks on the kingside.

Key Ideas
- The c8 bishop is Black's biggest problem — blocked by the e6 pawn, it needs to be activated via ...b6-Ba6 or ...f6.
- Black's main pawn break is ...c5, attacking d4 and freeing the queenside. Time this carefully.
- White attacks on the kingside (f4-f5, g4-g5) while Black counterattacks on the queenside (c5, b5, a5).
- The e5 pawn is White's space advantage — Black must attack it with ...f6 to loosen White's grip.
- King safety: White often castles queenside to launch a kingside pawn storm; Black should do the same.
- The pawn structure is asymmetric — both sides attack in opposite directions, creating double-edged positions.
