French Defence

Black develops the knight to f6, directly challenging the e4 pawn. Play revolves around White's decision to push e5 or maintain the tension. The classical approach leads to rich strategic middlegames where Black aims for the ...e5 or ...c5 breaks to free the position.

1. e4 e6 2. d4 d5 3. Nc3 Nf6…

White plays 3.Nd2 instead of Nc3, avoiding the Winawer pin and keeping a flexible pawn structure. The Tarrasch leads to more positional, slower games where White builds up gradually and Black must find the right moment to break with ...c5.

1. e4 e6 2. d4 d5 3. Nd2…

White locks the centre with 3.e5, creating a pawn chain that defines the character of the game. Black immediately undermines it with ...c5, attacking the base of the chain. The resulting positions feature a clear strategic battle: White attacks on the kingside while Black counter-attacks on the queenside.

1. e4 e6 2. d4 d5 3. e5 c5…

White trades pawns on d5 early, leading to a symmetrical structure. Though often considered drawish, White can press for a small advantage with the bishop pair and active piece play. Black should aim for quick development and activity to neutralise White's initiative.

1. e4 e6 2. d4 d5 3. exd5 exd5…

Black captures on e4 with 3...dxe4, giving up the centre early in exchange for free and easy development. The resulting positions are solid but slightly passive for Black, who must generate counterplay before White's spatial advantage becomes overwhelming.

1. e4 e6 2. d4 d5 3. Nc3 dxe4…

A sharp sub-line of the Classical where Black answers 4.Bg5 with 4...Bb4, pinning the knight and provoking complications. The MacCutcheon leads to double-edged positions with mutual chances, rewarding players who know the tactical motifs and accurate move orders.

1. e4 e6 2. d4 d5 3. Nc3 Nf6…

The mainline continuation of the Classical after 4.e5 Nfd7 5.Nf3, where White develops naturally while maintaining the pawn chain. Black prepares the key ...c5 break to attack White's centre, leading to strategic battles around the d4/e5 pawn tension.

1. e4 e6 2. d4 d5 3. Nc3 Nf6…

After 3.Nc3 Nf6 4.Bg5, Black plays the principled 4...dxe4, simplifying the centre and aiming for a comfortable structure with the bishop pair. The Burn avoids the heavy theory of the Winawer and MacCutcheon while still giving Black active piece play. White retains a slight space advantage but Black's position is solid and easy to handle.

1. e4 e6 2. d4 d5 3. Nc3 Nf6…

The classical Winawer positional treatment with Nf3 and Bd3.

The calmer mainline where White declines the Poisoned Pawn with 7.Nf3 instead of 7.Qg4. Both sides develop classically, with White aiming for kingside pressure and Black targeting the doubled c-pawns and the dark squares. A deeply strategic battle where understanding outweighs memorisation.

1. e4 e6 2. d4 d5 3. Nc3 Bb4…

Pressing against Black's isolated queen's pawn in the Tarrasch.

Black plays the active 3...c5 against the Tarrasch, immediately challenging White's centre and accepting an isolated queen's pawn after the typical 4.exd5 exd5 5.Ngf3. The Open Tarrasch leads to dynamic positions with chances for both sides - White presses against the IQP while Black uses active piece play to compensate.

1. e4 e6 2. d4 d5 3. Nd2 c5…

Slow build-up with Bd3, c3, Ne2 and a kingside attack.

After 3...Nf6 4.e5 Nfd7, the Closed Tarrasch arises with a locked centre and slow strategic manoeuvring. White typically continues with Bd3, c3 and Ne2, building a kingside attack while Black prepares ...c5 and ...f6 breaks. Less sharp than the Open Tarrasch but rich in long-term strategic ideas.

1. e4 e6 2. d4 d5 3. Nd2 Nf6…

Securing the d4 pawn with a3 and b4 before launching kingside play.

The classical mainline of the Advance, where after 5.Nf3 Qb6 6.a3, White prepares b4 to gain queenside space and protect the d4 pawn. Named after Aaron Nimzowitsch, who pioneered the modern handling of the Advance French. Both sides build patiently before the position erupts in the middlegame.

1. e4 e6 2. d4 d5 3. e5 c5…

Solving the bad bishop problem before releasing central tension.

Black develops the problem bishop to d7 before ...Nge7, keeping the option of ...Bb5 to trade it off. A modern, flexible way to pressure d4 without allowing White's usual Milner-Barry tricks.

1. e4 e6 2. d4 d5 3. e5 c5…

A rock-solid structure with easy development and ...c5 counterplay.

Black trades in the centre and recaptures with the knight from d7, aiming for a solid structure with ...c5 to follow. Simple to learn, hard to break down, and a favourite of practical defenders.

1. e4 e6 2. d4 d5 3. Nc3 dxe4…

Playing symmetrical positions actively rather than passively.

White tries to inject life into the Exchange Variation with an early c4, taking on an isolated pawn structure for activity. Black develops smoothly and targets the d4 and c5 squares.

1. e4 e6 2. d4 d5 3. exd5 exd5…

Navigating the Winawer's sharpest tactical battleground.

The sharpest line of the entire French, where after 7.Qg4 Qc7 8.Qxg7 Rg8 9.Qxh7 cxd4 White grabs both wing pawns while Black gets a huge lead in development and open lines. One of the most theory-heavy variations in chess - both sides walk a tactical tightrope where a single inaccuracy decides the game.

1. e4 e6 2. d4 d5 3. Nc3 Bb4…

Sacrificing the d-pawn for rapid development and king attack.

In the Advance, White sacrifices the d4 pawn with 8.O-O Nxd4 9.Nxd4 Qxd4 10.Nc3, gaining rapid development and attacking chances against Black's exposed queen and uncastled king. Named after British master Stuart Milner-Barry, this aggressive gambit catches unprepared opponents off guard with sharp tactical play.

1. e4 e6 2. d4 d5 3. e5 c5…

Building a massive pawn centre with d4-e5-f4 and kingside attack.

After 4.e5 Nfd7, White plays the aggressive 5.f4, building a powerful pawn centre with d4-e5-f4 and preparing a kingside attack. Named after the first world champion Wilhelm Steinitz, this sharp treatment of the Classical demands precise play from Black, who must counter quickly with ...c5 and ...Nc6 before White's attack arrives.

1. e4 e6 2. d4 d5 3. Nc3 Nf6…

Sacrificing a pawn with h4 for the open h-file and kingside attack.

After 4.Bg5 Be7 5.e5 Nfd7, White plays the aggressive 6.h4, sacrificing a pawn for a ferocious kingside attack. If Black accepts with ...Bxg5 7.hxg5 Qxg5, White gets the open h-file and a huge lead in development. A romantic, ambitious system that demands precise preparation from both sides.

1. e4 e6 2. d4 d5 3. Nc3 Nf6…

Trading structure for development and open files in the Winawer.

White challenges the pin at once with 4.a3, and after the trade on c3 grabs the g-pawn with Qg4. Black gets a big lead in development and open lines against White's damaged structure.

1. e4 e6 2. d4 d5 3. Nc3 Bb4…

Meeting an early Qg4 attack with active piece counterplay.

Black pins with ...Bb4 and grabs the initiative after ...Ne4 and the exchange on c3. White chases the king with Qg4, but Black's central pressure and dark-square play offer full counterchances.

1. e4 e6 2. d4 d5 3. Nc3 Nf6…

White sidesteps mainstream French theory with 2.d3, intending a King's Indian Attack setup with Nd2, Ngf3, g3, Bg2 and O-O. The KIA leads to slow, strategic positions where White builds a kingside attack with e4-e5 and Nf1-h2-g4. Black often expands on the queenside with ...c5, ...Nc6 and ...b5, leading to opposite-side play.

1. e4 e6 2. d3 d5 3. Nd2 Nf6…

Black's flexible ...Be7 system that sidesteps mainstream theory.

Black plays the offbeat 3...Be7, sidestepping all Tarrasch theory while keeping the position flexible. Popularised by Morozevich and other modern players, the Universal System is hard to refute - Black can transpose into Closed Tarrasch structures or steer into unique positions depending on White's reply.

1. e4 e6 2. d4 d5 3. Nd2 Be7…

Black's ultra-solid Bd7-c6 setup that trades off the dangerous e4 knight.

Within the Rubinstein, Black develops the light-squared bishop with ...Bd7-c6, exchanging it for White's strong knight on e4. The resulting structure is extremely solid - hence the 'Fort Knox' nickname - though slightly passive. Black accepts a long defensive game in exchange for near-impregnable positions, ideal for players seeking a draw or aiming to outplay opponents in the endgame.

1. e4 e6 2. d4 d5 3. Nc3 dxe4…

Undermining White's centre with ...f6 in a low-theory Tarrasch.

Black develops the queen's knight to c6 rather than playing ...c5, then undermines the e5 pawn with ...f6. It sidesteps huge amounts of Tarrasch theory and leads to structures Black can learn quickly.

1. e4 e6 2. d4 d5 3. Nd2 Nc6…

Defending the kingside while grinding White's weak c-pawns.

Instead of grabbing the b2 pawn, Black castles into the attack, trusting the solid structure to hold. Play revolves around the f-file and Black's queenside break with ...c4 or ...Qa5.

1. e4 e6 2. d4 d5 3. Nc3 Bb4…

Fast development and open lines instead of the usual French squeeze.

Black recaptures on d5 with the queen, accepting an isolated pawn structure in return for free development and the bishop pair. Sharp, dynamic play that avoids the usual French cramp.
