Harrwitz Attack starting position
White chooses Bf4 instead of Bg5. The bishop keeps pressure without inviting the same Lasker-style ...Ne4 exchanges that often simplify the Bg5 lines.
Example sequence: 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Nf3 Be7 5. Bf4
QGD Harrwitz Attack: Bf4 Anti-Simplification System
The Harrwitz Attack starts with 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 Be7 5.Bf4. White develops naturally, avoids some of Black's easiest Lasker-style exchanges, and keeps options for dxc5, a3/Qc2, or the ambitious c4-c5 space clamp.
Quick recommendation
Use the Harrwitz when you want a Queen's Gambit Declined weapon that is principled but less automatic than the old Bg5 main lines. The bishop on f4 keeps Black honest: if Black plays passively, White gains space; if Black plays actively, the structure becomes rich very quickly.
- White's identity: Bf4 development, e3, flexible central tension.
- Main test: 5...O-O 6.e3 c5 7.dxc5 Bxc5.
- Space route: c4-c5, b4 and sometimes h4/Bh2 against ...Nh5.
- Replay focus: Leko-Kramnik 2004 and Anand-Carlsen 2014 are the headline World Championship models.

Key diagrams and practice positions
Each diagram uses a python-chess validated FEN from the stated move sequence, with a direct example sequence below the board.
Main line with ...c5 and dxc5
The practical main line continues with castling, e3, ...c5 and dxc5. White gets active development while Black tries to equalise by recovering c5 cleanly.
Example sequence: 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Nf3 Be7 5. Bf4 O-O 6. e3 c5 7. dxc5 Bxc5
a3 and Qc2 tabiya
The a3 and Qc2 setup is a sharp Harrwitz tabiya. White prepares queenside expansion or long castling while asking Black how to develop the queen and queenside pieces.
Example sequence: 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Be7 5. Bf4 O-O 6. e3 c5 7. dxc5 Bxc5 8. a3 Nc6 9. Qc2 Qa5
Leko-Kramnik isolani structure
The Leko-Kramnik World Championship structure arises after exchanges on d5. White blockades and targets the isolated d-pawn while keeping long-term pressure.
Example sequence: 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Be7 5. Bf4 O-O 6. e3 c5 7. dxc5 Bxc5 8. cxd5 Nxd5 9. Nxd5 exd5 10. a3 Nc6 11. Bd3 Bb6 12. O-O
7.c5 space-gaining system
White can avoid early exchanges and play c4-c5, taking space and asking Black to justify the ...Nbd7 and ...Nh5 plan.
Example sequence: 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Be7 5. Bf4 O-O 6. e3 Nbd7 7. c5 Nh5 8. Bd3 Nxf4 9. exf4 b6 10. b4
Anand-Carlsen c-pawn wedge
In the 2014 World Championship, Anand used the Harrwitz c-pawn wedge to disrupt Blacks coordination and create tactical pressure on the queenside.
Example sequence: 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Be7 5. Bf4 O-O 6. e3 Nbd7 7. c5 c6 8. Bd3 b6 9. b4 a5 10. a3 Ba6 11. Bxa6 Rxa6 12. b5 cxb5 13. c6
Topalov h4 attacking plan
Topalov showed that h4 and Bh2 can give White a direct kingside plan when Black challenges Bf4 with ...Nh5 and ...f5.
Example sequence: 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Be7 5. Bf4 O-O 6. e3 Nbd7 7. c5 Nh5 8. Be5 c6 9. Bd3 g6 10. h4 f5 11. Bh2 b6 12. b4
Be2 and ...dxc4 route
Black often uses ...dxc4 against Be2 systems. White recaptures later, but Black may win time for ...Nb6, ...Nh5 or central counterplay.
Example sequence: 1. d4 d5 2. c4 e6 3. Nc3 Be7 4. Nf3 Nf6 5. Bf4 O-O 6. e3 Nbd7 7. Be2 dxc4 8. O-O Nb6 9. Qc2 Nh5
Variation map
5.Bf4
The Harrwitz move: active development without entering the most familiar Bg5 exchange channels.
...c5 and dxc5
The central main line: White clarifies the centre and asks Black to solve development.
c5 space clamp
White grabs space and aims for b4-b5, c-pawn wedges, and queenside pressure.
World Championship models
Leko-Kramnik shows technical pressure; Anand-Carlsen shows a tactical c-pawn wedge.
Plans for White
- Use Bf4 to reduce easy simplification: Black cannot always rely on the same ...Ne4 patterns seen in Bg5 lines.
- Choose the centre early: dxc5 is direct, cxd5 creates isolani targets, and c5 grabs space.
- Use a3 and Qc2 for flexibility: these moves support queenside play, castling choices, and tactical pressure.
- Meet ...Nh5 with a plan: Bd3/exf4 can give White space, while Be5/Bh2 can support kingside ideas.
- Study the World Championship games: Leko-Kramnik and Anand-Carlsen show the opening's practical ceiling.
Plans for Black
- Challenge the centre: ...c5 and ...dxc4 are the key counterblows.
- Question Bf4: ...Nh5 can remove or damage White's bishop setup.
- Do not drift: passive development lets White gain space with c5 and b4-b5.
- Use queenside counterplay: ...a5, ...b6 and open files are often essential against c5 systems.
- Prefer activity over structure-only defence: Black must create play before White's clamp becomes permanent.

QGD Harrwitz Attack FAQs
Basics and move order
What is the QGD Harrwitz Attack?
The QGD Harrwitz Attack is the Queen's Gambit Declined line with 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 Be7 5.Bf4. White develops the bishop to f4 instead of g5 to keep pressure while avoiding some of Black's easiest Lasker-style exchanges. Start with the Harrwitz Attack starting position diagram.
Why does White play Bf4 instead of Bg5?
Bf4 makes it harder for Black to use the standard ...Ne4 exchange ideas that often simplify against Bg5. White keeps the bishop active and preserves more tension. Use the Harrwitz Attack starting position diagram.
What is the main Harrwitz Attack continuation?
A common continuation is 5...O-O 6.e3 c5 7.dxc5 Bxc5, followed by a3, Qc2, or Be2 depending on White's plan. Use the Main line with ...c5 and dxc5 diagram.
Is the Harrwitz Attack a main-line QGD weapon?
Yes. It has been used in World Championship games and by elite players because it gives White a flexible, low-risk way to avoid some of Black's most comfortable Queen's Gambit Declined setups. Use the Replay Lab for Leko-Kramnik and Anand-Carlsen.
Is the Harrwitz Attack good for club players?
Yes, because the plans are easier to understand than many sharp QGD main lines: develop Bf4, play e3, choose between dxc5, c5, or a3/Qc2, and watch Black's ...Nh5 ideas. Start with the adviser and the c5 space-gaining system diagram.
White plans
What is White's plan after 5.Bf4 O-O 6.e3 c5?
White can capture on c5, develop with a3 and Qc2, or exchange on d5 and play against an isolated pawn. The exact choice depends on whether White wants activity, structure, or a long squeeze. Use the Main line with ...c5 and dxc5 diagram.
When should White play a3 and Qc2?
White plays a3 and Qc2 to create a flexible tabiya where long castling, queenside expansion, and central captures are all possible. It is sharper than the quiet Be2 setups. Use the a3 and Qc2 tabiya diagram.
What is the c5 space-gaining system?
White plays c4-c5 to gain queenside space and reduce Black's central counterplay. Black usually challenges the bishop with ...Nh5 and tries ...b6 or ...c6 breaks. Use the 7.c5 space-gaining system diagram.
Why is the Anand-Carlsen Harrwitz game important?
Anand beat Carlsen in the 2014 World Championship with a c5 and c6 wedge, showing that the Harrwitz can be used at the highest level as a direct strategic weapon. Use the Anand-Carlsen c-pawn wedge diagram and load Anand vs Carlsen in the Replay Lab.
What is the Leko-Kramnik plan?
Leko used Bf4 to reach a structure where White blockaded and pressured Black's isolated d-pawn. It became a famous World Championship example of long-term technical pressure. Use the Leko-Kramnik isolani structure diagram.
Black replies
What is Black's safest reply to the Harrwitz Attack?
Black often plays 5...O-O followed by ...c5, or uses ...Nbd7 and ...dxc4 depending on White's move order. The safest plan is to avoid drifting into a passive isolani or cramped c5 structure. Use the Main line with ...c5 and dxc5 diagram.
Why does Black play ...Nh5 against Bf4?
...Nh5 asks White to surrender the Bf4 bishop or allow structural changes with exf4. It is especially common when White plays c5 and Bd3. Use the 7.c5 space-gaining system diagram.
What is the ...dxc4 route for Black?
Black captures on c4 to make White spend a tempo recovering the pawn and to gain time for ...Nbd7, ...Nb6, ...Nh5, or ...c5. Use the Be2 and ...dxc4 route diagram.
Can Black play for a win against the Harrwitz?
Yes. The Harrwitz is solid for White, but Black can play actively with ...dxc4, ...Nh5, ...c5, queenside counterplay, or central breaks. Use the Black wins and counterplay model games in the Replay Lab.
What should Black avoid?
Black should avoid allowing White to combine c5, b4-b5, and a dangerous passed c-pawn without counterplay. The Anand-Carlsen c-pawn wedge diagram shows how quickly the queenside can become dangerous.
Replay and training
Which replay is best for the World Championship Harrwitz Attack?
Leko vs Kramnik 2004 and Anand vs Carlsen 2014 are the key World Championship replays. Leko shows long-term technical pressure, while Anand shows the c-pawn wedge. Load either game after the matching diagram.
Which replay is best for a Black win?
Carlsen vs Ivanchuk, Giri vs Aronian, and Giri vs Topalov are useful Black-win models. They show how Black can generate counterplay if White's setup becomes slow. Use the Black wins and counterplay group in the Replay Lab.
Which replay is best for the c5 space system?
Topalov vs Kramnik 2014, Anand vs Carlsen 2014, and Aronian vs Giri 2011 are strong c5-space examples. Study the 7.c5 space-gaining system diagram first.
How should I train the Harrwitz Attack in 10 minutes?
Study the starting Bf4 diagram, the ...c5/dxc5 main line, and the c5 space-gaining system. Then replay Leko-Kramnik and Anand-Carlsen. Use the adviser if you want a side-specific plan.
What should I remember most about the Harrwitz Attack?
Remember that Bf4 is a practical anti-simplification choice. White keeps pressure without entering the most familiar Bg5 exchanges, while Black must find active counterplay. Use the Harrwitz starting diagram and Replay Lab as your anchor.
Train the Harrwitz Attack structure
Start with Bf4, choose your central plan, then test it against a supplied World Championship or elite model game in the Replay Lab.
