French Defense: Tarrasch Variation, Guimard Defense, Main Line

Before the first move

The Guimard Defense is a provocative and flexible weapon against the Tarrasch French. By developing your knight to c6 early, you pressure the d4-pawn and force White to make a decision in the center. It avoids the traditional cramped structures of the French Defense in favor of active piece play and immediate counter-pressure.

1. e4White

White plays e4, the most popular starting move. By controlling d5 and f5, White invites an open game. You will have to decide how to respond: the solid French Defense with e6, the symmetrical e5, or perhaps the sharp Sicilian Defense with c5.

1... e6Black · your move

Move your pawn to e6. This defines the French Defense, preparing to challenge the center with d5 on your next turn. While it temporarily blocks your light-squared bishop, it creates a very sturdy structure that is difficult for White to break down quickly.

Other paths here: f6 (Barnes Defense) · g5 (Borg Defense) · h6 (Carr Defense) · f5 (Duras Gambit)

2. d4White

White plays d4, establishing a full pawn center. You now have a choice of how to challenge this. The main line is d5, but some players experiment with the Franco-Sicilian c5 or even the Banzai-Leong Gambit with b4. Sticking to the main road is usually safest.

Other paths here: b4 (French Defense: Banzai-Leong Gambit) · Bb5 (French Defense: Bird Invitation) · Qe2 (French Defense: Chigorin Variation) · b3 (French Defense: Horwitz Attack)

2... d5Black · your move

Advance your pawn to d5. You are directly challenging White's e4-pawn and establishing your own foothold in the center. This move creates immediate tension, forcing White to decide whether to push, capture, or defend their central pawn.

Other paths here: b5 (French Defense: Baeuerle Gambit) · f5 (French Defense: Franco-Hiva Gambit) · c5 (French Defense: Franco-Sicilian Defense) · Nf6 (French Defense: Mediterranean Defense)

3. Nd2White

White plays Nd2, the Tarrasch Variation. This is a refined approach that avoids the pins of the Winawer. While the Advance Variation with e5 is also common, Nd2 is favored by players who prefer a more positional struggle. White could also try the Schlechter Variation with Bd3.

Other paths here: Be3 (French Defense: Alapin Gambit) · c4 (French Defense: Diemer-Duhm Gambit) · Nh3 (French Defense: Morphy Gambit) · Nf3 (French Defense: Perseus Gambit)

3... Nc6Black · your move

Develop your knight to c6. This is the Guimard Defense. You are putting immediate pressure on the d4-pawn, which is unusual for the French. This move challenges White's setup and prepares to increase the tension in the center very quickly.

Other paths here: f5 (French Defense: Tarrasch Variation, Haberditz Variation) · a6 (French Defense: Tarrasch Variation, Modern System) · Be7 (French Defense: Tarrasch Variation, Morozevich Variation) · b6 (French: Tarrasch, 3...b6)

4. Ngf3White

White plays Ngf3, defending d4 and continuing development. This is the main line of the Guimard. White could also try 4.c3 to bolster the center further, but developing the knight is more active and prepares the king for safety much faster.

Other paths here: c3 (French: Tarrasch, Guimard, 4.c3)

4... Nf6Black · your move

Develop your other knight to f6. You are now attacking the e4-pawn and putting maximum pressure on White's center. This move completes your minor piece development on the kingside and prepares you to castle, maintaining a flexible and energetic position.

Where you stand

The position is tense and full of life. White will likely push e5 to gain space, while Black will look to relocate the knights and strike at the base of the pawn chain. Both sides must balance their central control with the need to safeguard their kings. Expect a maneuvering battle where square control is everything.

• e4-e5 White gains space by pushing e5
• f6-d7 Black knight retreats to d7 after e5
• f1-e2 White prepares to castle kingside
• f8-e7 Black develops the bishop to castle
• d2-b3 White knight moves to support the center
