C00-C99

The starting point of the French Defense. Black creates a solid but cramped position, aiming to counter-attack White's central pawn chain later.

The Exchange Variation. White resolves the tension immediately, leading to a symmetrical and often drawish structure where endgame skill is key.

The Advance Variation. White locks the center and gains space. Black immediately pressures the d4 and c5 squares to dismantle White's overextended chain.

The Tarrasch Variation. White develops the knight to d2 to avoid the Winawer pin. It is a solid, positional approach preferred by players seeking a stable edge.

A sharp sideline within the Tarrasch. Black develops the knight to c6 early to put immediate tactical pressure on White’s center.

The Closed Tarrasch. Both sides build up their positions behind fixed pawn chains. It leads to deep strategic maneuvering and long-term planning.

The theoretical main line of the Closed Tarrasch. White focuses on king-side space while Black organizes a counter-strike on the queen-side.

The Open Tarrasch. Black challenges the center with c5, leading to an isolated queen's pawn for Black but giving them very active piece play.

A refined version of the Open Tarrasch. White accepts the exchange on d5 to simplify the position while maintaining a slight positional squeeze.

The main line of the Open Tarrasch. A highly technical struggle where White tries to prove the central space is more valuable than Black’s activity.
