Alekhine-Chatard Attack: 6.h4 Interactive Guide

The Alekhine-Chatard Attack begins after 1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Be7 5.e5 Nfd7 6.h4. White offers a dangerous attacking idea: open the h-file, disturb Black's king safety, and make normal French Defense development harder to coordinate.

Use this page to compare the accepted gambit with 6...Bxg5, the important declined line 6...c5, the aggressive 6...a6 7.Qg4 branch, and modern counterplay systems.

  • Main position: 1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Be7 5.e5 Nfd7 6.h4
  • White idea: open the h-file, castle long, and use queen pressure against Black's king
  • Black idea: challenge the centre, return material when needed, and avoid passive king defence
  • Branch check: 6...Bxg5 accepts; 6...c5, 6...a6, 6...h6, 6...O-O, and 6...Nc6 decline or sidestep

Four diagrams that explain the Alekhine-Chatard Attack

These diagrams show the starting gambit, the accepted h-file structure, the 6...a6 Qg4 idea, and the 6...c5 king-decision line.

Alekhine-Chatard starting point after 6.h4

White asks whether Black will take the bishop, decline the pawn, or hit the centre.

Accepted gambit after 8...Qxg5

Black wins a pawn, but White has an open h-file and fast attacking chances.

Declined with 6...a6 7.Qg4

White threatens Bxe7 and pressure on g7, forcing Black to solve kingside problems.

6...c5 and the king decision

Black fights the centre but often gives up castling rights after Kxe7.

Focus Plan: Start with 6...Bxg5 7.hxg5 Qxg5 and learn how Qd3, Nh3, long castling, and the h-file create compensation.

Discovery Tip: Then load Sax vs Bareev to see how Black can survive by counterattacking instead of defending passively.

Branch map: how 6.h4 changes the French Defense

The Alekhine-Chatard Attack is not one forcing line. Black's sixth move decides whether the game becomes an accepted gambit, a central king fight, or a delayed kingside storm.

Accepted: 6...Bxg5

Black wins material but opens the h-file and must solve king safety before White's attack accelerates.

Declined: 6...c5

Black challenges d4 immediately, often accepting Kxe7 and a central king instead of allowing Nb5 tactics.

Declined: 6...a6

Black waits, but 7.Qg4 threatens Bxe7 and Qxg7, often forcing the bishop capture anyway.

Modern counterplay

Black can use ...Nc6, ...O-O, ...f6, or piece activity, but passive defence usually fails.

Suggested path: Kasparov vs Kortschnoj, Khalifman vs Gurevich, Sakaev vs Ulibin, Sax vs Bareev, then Nataf vs Morozevich.

Plans for White

  • Use the h-file: after hxg5, White's rook can become a direct attacking piece instead of a corner spectator.
  • Castle long: queenside castling often connects the rooks and keeps the kingside free for pawn and rook pressure.
  • Choose Qd3 or Qg4 with purpose: Qd3 is flexible in accepted lines; Qg4 is often immediate against 6...a6.
  • Do not attack slowly: the pawn sacrifice works only if development and file pressure arrive before Black consolidates.

Plans for Black

  • Decide whether to accept: 6...Bxg5 wins material but opens the h-file and requires exact defence.
  • Challenge the centre: ...c5, ...Nc6, and ...f6 are often more important than clinging to an extra pawn.
  • Return material if needed: king safety and development are worth more than a single pawn in this gambit.
  • Know the Nb5 tactic: after 6...c5 7.Bxe7, careless ...Qxe7 can allow 8.Nb5 with serious threats.

Alekhine-Chatard basics

What is the Alekhine-Chatard Attack?

The Alekhine-Chatard Attack is the French Defense line 1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Be7 5.e5 Nfd7 6.h4. White offers the h-pawn idea to open attacking lines, disturb Black's king safety, and make normal French development less comfortable. Start with the Alekhine-Chatard starting point after 6.h4 diagram to see why the h-file and g5-bishop define the attack.

Is it called the Alekhine-Chatard Attack or the Albin-Chatard Attack?

Both names are used, because the idea is associated with Adolf Albin, Chatard, and later Alekhine's famous practical use. Modern players usually recognise the line as the Alekhine-Chatard Attack, while some opening sources preserve the Albin-Chatard name. Use the Name and move-order notes in the adviser output to keep the historical label separate from the actual 6.h4 move order.

What is the exact move order for the Alekhine-Chatard Attack?

The exact move order is 1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Be7 5.e5 Nfd7 6.h4. The line belongs to the Classical French with 4...Be7, not to the Burn Variation or Winawer. Study the starting diagram and then replay Kasparov (White) vs Kortschnoj (Black) to anchor the move order in a real game.

Why does White play 6.h4?

White plays 6.h4 to invite a dangerous attacking structure and make Black decide whether to accept the pawn or decline the gambit. If Black captures on g5 and then takes on g5 with the queen, White often gains open h-file pressure, dark-square chances, and a central king target. Use the Accepted gambit after 8...Qxg5 diagram to see the pawn sacrifice mechanism.

What is White sacrificing in the Alekhine-Chatard Attack?

White usually sacrifices the h-pawn or allows Black to win a kingside pawn in return for time and attacking lines. The compensation is based on open files, fast development, pressure on g6 and h7, and the difficulty Black has finding a safe king. Replay Grischuk (White) vs Brynell (Black) in the Replay Lab to see how modern attacking players use that compensation.

Is the Alekhine-Chatard Attack sound?

The Alekhine-Chatard Attack is playable but sharp, and it demands accurate attacking play from White. Black has several serious defensive choices, including accepting with 6...Bxg5, declining with 6...c5, declining with 6...a6, or using immediate counterplay with 6...O-O or 6...Nc6. Use the Alekhine-Chatard Adviser to choose a study route before trying the gambit in games.

Is 6.h4 a beginner-friendly move?

6.h4 is not the easiest beginner move because White often sacrifices material and must understand attacking timing. The move is easier to handle after learning the three core branches: accepted, 6...c5 declined, and 6...a6 declined. Use the Branch map section to divide the opening into those three practical decisions.

Why is the black king often stuck in the centre?

The black king is often stuck in the centre because castling kingside may walk into an open h-file attack, while castling queenside can be slow or impossible after ...c5. White's pawn sacrifice is designed to make normal safety moves feel awkward rather than merely winning time. Replay Benjamin (White) vs Seirawan (Black) to see how 6...c5 can force Black's king to e7.

What is the main idea of 8.Nh3?

The main idea of 8.Nh3 is to prepare Qg4 while keeping the knight flexible for g5 or f4. In the accepted gambit, 8.Nh3 is often more purposeful than 8.Nf3 because White wants quick queen pressure on g4. Use the Accepted gambit after 8...Qxg5 diagram and trace the Nh3-Qg4-Ng5 route visually.

What is the main idea of 8.Qd3?

The main idea of 8.Qd3 is to support kingside pressure while preparing long castling and keeping several attacking options open. The queen can later influence h7, g6, and the centre without committing the knight immediately. Replay Kasparov (White) vs Kortschnoj (Black) to study a high-level 8.Qd3 treatment.

Accepted and declined systems

What happens after 6...Bxg5?

After 6...Bxg5, White usually plays 7.hxg5 and invites 7...Qxg5, entering the accepted gambit. White gives material but opens the h-file and gains attacking chances against a king that often cannot castle comfortably. Load Kasparov (White) vs Kortschnoj (Black) in the Replay Lab to study the accepted structure.

What happens after 6...a6?

After 6...a6, White can continue with 7.Qg4, threatening Bxe7 and pressure on g7. Black often still captures on g5 to remove the bishop, but the h-file opens and unsafe kings become the theme. Replay Khalifman (White) vs Gurevich (Black) to study the 6...a6 declined branch.

What happens after 6...h6?

After 6...h6, White usually trades with 7.Bxe7 Qxe7 and then builds a kingside pawn storm with f4 and g4. This is a safer declination because Black avoids immediately opening the h-file, but White can still attack if Black later castles kingside. Use the Declined with 6...h6 plan from the wiki-derived notes to compare safety with ambition.

What happens after 6...c5?

After 6...c5, White often plays 7.Bxe7 and Black must choose between 7...Kxe7 and allowing tactical problems after 7...Qxe7 8.Nb5. This is one of the most important declined systems because it challenges White's centre while accepting king-move inconvenience. Replay Sakaev (White) vs Ulibin (Black) to study a 6...c5 declined battle.

Why is 7...Qxe7 risky after 6...c5 7.Bxe7?

7...Qxe7 is risky because 8.Nb5 can create threats such as Nc7+ against the rook on a8 and Nd6+ with a powerful knight near the king. This tactical point is a core reason Black often chooses 7...Kxe7 instead. Use the Branch map section to keep the 6...c5 decision tied to the Nb5 tactical warning.

Why does Black sometimes play 7...Kxe7?

Black plays 7...Kxe7 after 6...c5 7.Bxe7 to avoid the immediate 8.Nb5 tactical fork ideas. The price is that Black's king loses castling rights and must survive in the centre or walk to safety later. Replay Benjamin (White) vs Seirawan (Black) to see how the exposed king becomes the central practical question.

Is 6...O-O a good answer to the Alekhine-Chatard Attack?

6...O-O is playable but committal because Black castles into the side where White wants to attack. White can answer with Nh3, Qg4, f4, h5, or direct pawn pressure depending on the setup. Replay Hector (White) vs Moskalenko (Black) to see how castling kingside can lead to a long tactical struggle.

Is 6...Nc6 a serious reply?

6...Nc6 is a serious reply that develops and asks White to prove the attack before the h-file fully opens. It can transpose into sharp structures with Qg4, f6, Bf4, or a later h-file race. Replay Nataf (White) vs Morozevich (Black) and Peralta (White) vs Oreopoulos (Black) to compare two 6...Nc6 structures.

What is the safest decline for Black?

The safest decline is often 6...h6 because it asks White to trade the bishop without immediately opening the h-file. Black still must handle f4 and g4 attacking plans, but the king is less exposed than in many accepted lines. Use the Alekhine-Chatard Adviser with 'Black wants safety first' to choose the safer defensive route.

What is the sharpest acceptance for Black?

The sharpest acceptance is 6...Bxg5 7.hxg5 Qxg5, when Black grabs material and White gains attacking lines. Black must be ready for Nh3, Qd3, Qg4, long castling, and pressure on the dark squares. Replay Grischuk (White) vs Brynell (Black) to see how dangerous the accepted branch can become.

Plans for White

What is White's main attacking plan?

White's main attacking plan is to open the h-file, castle long, and use queen and rook pressure against Black's king. The attack often uses Qd3 or Qg4, Nh3-g5, Rh3, Rdh1, and central breaks when Black over-defends the kingside. Use the Alekhine-Chatard Adviser with 'White wants attack patterns' to jump into the right replay group.

Should White castle queenside?

White should often castle queenside because the kingside pawns and h-file are usually part of the attack. Long castling also brings the d-rook toward the centre and keeps the h-rook ready for pressure. Replay Velimirovic (White) vs Kovacevic (Black) to study a classic queenside-castling attacking setup.

When should White play Qg4?

White should play Qg4 when the queen can pressure g7, support Bxe7 ideas, or coordinate with Nh3-g5. The move is especially important after 6...a6, where White threatens Bxe7 and Qxg7. Use the Declined with 6...a6 diagram to visualise why Qg4 is so direct.

When should White play Qd3?

White should play Qd3 when White wants a flexible accepted-gambit setup with long castling and pressure along the h-file. Qd3 supports kingside play while avoiding early queen exposure on g4. Replay Kasparov (White) vs Kortschnoj (Black) to see Qd3 used in a precise high-level attack.

Why does White use the h-file?

White uses the h-file because 6.h4 and hxg5 can open a direct rook lane toward Black's king. Even when queens come off, the h-file can support rook lifts, pressure on h7, and dangerous passed-pawn themes. Use the Accepted gambit after 8...Qxg5 diagram to see how the rook on h1 becomes active.

What is the role of the knight on h3?

The knight on h3 supports Qg4 ideas and can jump to g5 or f4 depending on Black's setup. It may look odd, but it is often more coordinated with the gambit than Nf3. Replay Dzhumaev (White) vs Ulibin (Black) to study an Nh3-based attacking plan.

What is the role of the bishop on g5?

The bishop on g5 is the piece that makes the Alekhine-Chatard Attack possible, because it provokes Black's decision after 6.h4. If Black captures it, the h-file opens; if Black declines, White may keep attacking pressure or exchange on e7. Use the starting diagram to see why the bishop and h-pawn work as one unit.

When should White switch from attack to endgame?

White should switch to an endgame when the attack has won structural concessions, exposed the king, or created dangerous passed pawns. Many Alekhine-Chatard games do not end in mate; they convert into rook, minor-piece, or pawn-race endings. Replay Sakaev (White) vs Ulibin (Black) to see the attack become a winning endgame.

What is White's biggest practical mistake?

White's biggest practical mistake is sacrificing the pawn and then playing slowly without opening files or developing the queenside. The gambit needs speed because Black's extra pawn and French structure become strong if White loses momentum. Use the Study path for this page section before choosing a replay game.

Which White model game should I start with?

White should start with Kasparov (White) vs Kortschnoj (Black) because it shows the accepted gambit with a world-class attacking hand. The game also illustrates how one inaccurate defensive setup can make Black's king collapse quickly. Load Kasparov (White) vs Kortschnoj (Black) from the Accepted gambit models group.

Plans for Black

What is Black's main defensive plan?

Black's main defensive plan is to return material when necessary, challenge the centre, and avoid walking into a forced h-file attack. Black should not treat the extra pawn as more important than king safety and piece coordination. Use the Alekhine-Chatard Adviser with 'Black wants safety first' to choose a defence-first route.

Should Black accept the gambit?

Black can accept the gambit, but only with accurate knowledge of the resulting king-safety problems. After 6...Bxg5 7.hxg5 Qxg5, Black has material but must handle Qd3, Nh3, Qg4, and long-castle pressure. Replay Sax (White) vs Bareev (Black) to study a successful Black handling of an accepted-style structure.

Should Black decline with 6...c5?

Black can decline with 6...c5 when Black is ready to meet 7.Bxe7 with a king move and active central play. The line is principled because it fights White's centre instead of only defending the kingside. Replay Zelcic (White) vs Gleizerov (Black) to see Black counterattack in the 6...c5 declined system.

Should Black decline with 6...a6?

Black can decline with 6...a6, but White's 7.Qg4 often keeps the position tactically dangerous. The move asks White to prove the attack, yet Black may still need to remove the g5-bishop and face an open h-file. Replay Degraeve (White) vs Gurevich (Black) to study a dangerous 6...a6 practical test.

Should Black decline with 6...h6?

Black can decline with 6...h6 when the main goal is to reduce immediate h-file danger. White usually trades on e7 and then tries f4 and g4, so Black must still prepare central counterplay. Use the Declined systems notes and compare them with the Replay Lab's 6...c5 examples.

Why is castling difficult for Black?

Castling is difficult for Black because the kingside may be opened by the h-file while queenside castling is often slowed by ...c5 requirements and central tension. The entire gambit is built around making normal king safety choices awkward. Replay Nataf (White) vs Riazantsev (Black) to see how Black's king route becomes the main story.

When should Black give back the pawn?

Black should give back the pawn when keeping it costs development, king safety, or control of the centre. In the Alekhine-Chatard Attack, one tempo can matter more than one pawn because open lines are already aimed at the king. Use the Adviser result for 'Black wants counterplay' to find a model game where Black survives by activity.

What is Black's central counterplay?

Black's central counterplay usually comes from ...c5, ...Nc6, ...f6, or timely exchanges that reduce White's attacking force. The French structure is most resilient when Black attacks d4 and e5 instead of passively guarding the kingside. Replay Morozevich (Black) against Nataf or Belov to see Black's counterpunching style.

What is Black's biggest practical mistake?

Black's biggest practical mistake is grabbing the pawn and then delaying development while the king remains exposed. If Black cannot coordinate the queen, knights, and central pawns quickly, White's compensation can become decisive. Use the Replay Lab to compare Kasparov vs Kortschnoj with Sax vs Bareev before choosing an accepted line.

Which Black model game should I start with?

Black should start with Sax (White) vs Bareev (Black) or Nataf (White) vs Morozevich (Black) for active defensive models. Both games show that Black must counterattack rather than simply endure White's initiative. Load Sax (White) vs Bareev (Black) in the Accepted gambit models group to begin the Black study path.

Study method and model games

What should I memorise first?

You should memorise the six-move identity first: 1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Be7 5.e5 Nfd7 6.h4. After that, learn the three major Black decisions: accept with 6...Bxg5, decline with 6...c5, or decline with 6...a6 or 6...h6. Use the Four diagrams that explain the Alekhine-Chatard Attack section as the visual memory base.

What is the fastest practical study plan?

The fastest practical study plan is one accepted game, one 6...c5 declined game, one 6...a6 declined game, and one Black counterattack game. This gives you the attacking and defensive skeleton without overloading on theory. Follow the Study path for this page and then replay Kasparov vs Kortschnoj, Sakaev vs Ulibin, Khalifman vs Gurevich, and Sax vs Bareev.

How many model games should I study?

Study at least six model games before adding the Alekhine-Chatard Attack to a serious repertoire. Choose two accepted games, two declined games, one White attacking win, and one Black defensive win. Use the Replay Lab optgroups to rotate through accepted, 6...c5 declined, 6...a6 declined, and modern counterplay examples.

Which game shows the accepted gambit best?

Kasparov (White) vs Kortschnoj (Black) is the clearest accepted-gambit starting model because it shows fast development, h-file pressure, and king danger. It also makes the Qd3 system easier to remember than a raw move list. Load Kasparov (White) vs Kortschnoj (Black) in the Replay Lab to study the accepted-gambit structure.

Which game shows the 6...a6 decline best?

Khalifman (White) vs Gurevich (Black) is a useful 6...a6 decline model because White answers with Qg4 and keeps attacking pressure. The game shows how Black's attempt to delay acceptance can still lead to kingside danger. Load Khalifman (White) vs Gurevich (Black) from the Declined with 6...a6 group.

Which game shows the 6...c5 decline best?

Sakaev (White) vs Ulibin (Black) is a useful 6...c5 decline model because it shows Black's king movement and White's central pressure. The game demonstrates why the line is not just a gambit acceptance question but a full central battle. Load Sakaev (White) vs Ulibin (Black) from the Declined with 6...c5 group.

Which game shows Black's counterplay best?

Nataf (White) vs Morozevich (Black) shows Black's counterplay best because Black uses development, central pressure, and active piece play rather than passive defence. It is a good warning that the Alekhine-Chatard Attack can backfire if White's attack slows. Load Nataf (White) vs Morozevich (Black) in the Modern counterplay group.

How should I use the Alekhine-Chatard Adviser?

Use the Alekhine-Chatard Adviser by choosing your side, the Black response, your study problem, and your goal. The adviser returns a named study archetype, star ratings, a concrete focus plan, and a replay or diagram action. Press Update my recommendation after changing a dropdown to build a repeatable Discover → Try → Adjust loop.

How should I use the diagrams?

Use the diagrams to remember the attack by structure rather than move-list alone. The key diagrams show 6.h4, the accepted gambit, 6...a6 with Qg4, and 6...c5 with the king decision. Start with the starting diagram, then use the Replay Lab to watch the same structures in motion.

How should I use the Replay Lab?

Use the Replay Lab by choosing one game from each optgroup instead of watching games randomly. The groups are designed to separate accepted gambits, 6...a6 declines, 6...c5 declines, and modern counterplay. Begin with Kasparov vs Kortschnoj, Khalifman vs Gurevich, Sakaev vs Ulibin, and Nataf vs Morozevich.

Is this a surprise weapon or a full repertoire line?

The Alekhine-Chatard Attack can be either a surprise weapon or a full repertoire line, but the preparation load changes. As a surprise weapon, learn one plan against each major Black response; as a repertoire line, study the accepted and declined structures in depth. Use the Adviser with 'Build a repertoire file' to turn the page into a structured training path.

What makes this page useful beyond a move list?

This page is useful beyond a move list because it connects the 6.h4 idea to diagrams, a diagnostic adviser, branch maps, FAQs, and replayable model games. The Alekhine-Chatard Attack is easier to play when every branch has a visual pattern and a named game attached. Use the Study path for this page to turn the adviser, diagrams, and Replay Lab into one training routine.
