Example move sequence1.e4 e5 2.f4 exf4 3.Nf3 d6
The King's Gambit Fischer Defense begins 1.e4 e5 2.f4 exf4 3.Nf3 d6. Black plays a waiting and containment move before committing to ...g5, often leading to the unusual main line 4.d4 g5 5.h4 g4 6.Ng1 or to 4.Bc4 h6 Hanstein-style structures.
This is the 3...d6 defense inside the King's Gambit Accepted.
Choose your side, route, problem and study time. The adviser points to the diagram or replay group that best fits the 3...d6 structure.
These python-chess checked diagrams use final-move arrows from each displayed sequence: 3...d6, 4.d4, ...g5, 6.Ng1, Bh6/Ne2, 4.Bc4 h6 and Hanstein-style O-O.

The King's Gambit Fischer Defense is 1.e4 e5 2.f4 exf4 3.Nf3 d6. Black delays ...g5, supports the centre and avoids some immediate romantic attacking lines. Use the Fischer Defense Start Diagram.
The exact anchor is 1.e4 e5 2.f4 exf4 3.Nf3 d6. White usually answers with 4.d4 or 4.Bc4. Use the Fischer Defense Start Diagram.
Yes. It comes after 2...exf4, so it is a King's Gambit Accepted defense, not a declined line. Use the Branch Map to return to the KGA page.
Bobby Fischer advocated 3...d6 after losing to Boris Spassky in a Kieseritzky Gambit. He called it a high-class waiting move. Use the Fischer Defense Start Diagram.
Black uses 3...d6 to support e5, slow White's central play and choose when to advance ...g5. Use the 4.d4 Main Line Diagram.
Delaying ...g5 lets Black see White's setup first and avoid some immediate 4.h4 or Kieseritzky-style pressure. Use the Fischer Defense Start Diagram.
It is one of Black's most respected accepted defenses to the King's Gambit, but the resulting positions are still sharp. Use the Replay Lab to compare White and Black models.
Yes, it is practical for club players because it gives Black a clear structure and avoids some forcing gambit traps. Use the Adviser with side set to Black.
The main line is often 4.d4 g5 5.h4 g4 6.Ng1. White retreats the knight in an unusual way and fights for central compensation. Use the 6.Ng1 Retreat Diagram.
White plays 6.Ng1 because after 4.d4 g5 5.h4 g4, the normal Kieseritzky-style 6.Ne5 is unavailable and 6.Ng5 can run into ...f6. Use the 6.Ng1 Retreat Diagram.
In the Fischer Defense structure, Black's ...d6 has already controlled e5, so the classic Kieseritzky knight jump is not the same solution. Use the 4...g5 Structure Diagram.
6.Ng5 can be dangerous because Black can answer with ...f6 in many lines and trap or embarrass the knight. Use the Adviser with goal set to main line.
After 6.Ng1, a typical plan is ...Bh6, Ne2, ...Qf6 and Nbc3. White tries to rebuild development and central pressure. Use the Bh6 and Ne2 Diagram.
After 4.d4 g5, Black commits the kingside pawns after first playing ...d6. White must prove compensation with h4, Ng1 and central play. Use the 4...g5 Structure Diagram.
Some Fischer Defense games use g3 and Black's ...f3 pawn wedge. White challenges Black's pawn chain while Black tries to cramp the kingside. Use the Replay Lab's g3 group.
Black wants to hold the f4 pawn only when it supports development and central control. The bigger goal is to limit White's centre. Use the Adviser with side set to Black.
After 4.Bc4, Black often plays 4...h6 or 4...g5. The line can transpose to Hanstein-style King's Gambit structures. Use the 4.Bc4 h6 Diagram.
A Hanstein-style setup can arise after 4.Bc4 h6 5.d4 g5 6.O-O Bg7. White develops actively, while Black keeps the kingside pawn chain. Use the Hanstein-style O-O Diagram.
Black plays 4...h6 to prepare ...g5 or support the kingside pawn chain while avoiding immediate h4 ideas. Use the 4.Bc4 h6 Diagram.
Yes, 4...Be6 is another reasonable Black reply because it develops and challenges White's bishop without immediate kingside commitment. Use the Branch Map after reviewing 4.Bc4 routes.
Immediate 4...g5 can be risky because White can answer with h4 and challenge the pawn chain before Black is ready. Use the Hanstein-style O-O Diagram.
5.h4 can stop or discourage ...g5, but it also weakens g3 and g4 squares. Use the Adviser with goal set to 4.Bc4 route.
Black should avoid treating the position as a simple pawn grab. White's bishop, castling and central play can become active quickly. Use the 4.Bc4 h6 and Hanstein diagrams.
Spassky vs Karpov and Vachier-Lagrave vs Ipatov are useful 4.Bc4 models from the supplied PGNs. Use the 4.Bc4 replay groups.
White wants to build a centre with d4, challenge Black's kingside pawns and avoid wasting time with misplaced knights. Use the Adviser with side set to White.
Black wants a controlled accepted structure: ...d6 first, then ...g5, ...h6, ...Bg7, ...Nf6 or ...Nc6 as appropriate. Use the Adviser with side set to Black.
4.d4 is the main central test, but 4.Bc4 is also important. Choose based on whether you want the 6.Ng1 main line or Hanstein-style development. Use the Adviser.
No. ...g5 is common, but Black should time it according to White's fourth move. Against 4.Bc4, premature ...g5 can be risky. Use the 4.Bc4 h6 Diagram.
White's biggest mistake is playing King's Gambit attacking moves without respecting the ...d6 structure. The e5 square and knight routes are different here. Use the 6.Ng1 Retreat Diagram.
Black's biggest mistake is assuming the Fischer Defense wins by itself. White still has serious central and attacking chances. Use the Replay Lab's White win groups.
The position after 6.Ng1 looks odd because neither side has developed a piece by move six, but White can still build a dangerous centre. Use the 6.Ng1 Retreat Diagram.
Remember it as King's Gambit Accepted plus ...d6 before ...g5. Black waits first, then builds the kingside structure. Use the Fischer Defense Start Diagram.
Start with Gallagher vs Ziatdinov for the 6.Ng1 main line, then compare Hector vs Leko for Black's practical counterplay. Use the Replay Lab selector.
Gallagher vs Ziatdinov, Hector vs Leko, Shulman vs Sulskis, Short vs Akopian, Fedorov vs Ibragimov and Fedorov vs Gyimesi show 4.d4 g5 5.h4 g4 6.Ng1 themes. Use the main-line replay groups.
Hector vs Leko, Gallagher vs Kuzmin, Morozevich vs Kasparov, Hernandez vs Schlosser, Zvjaginsev vs Akopian and Vachier-Lagrave vs Ipatov show Black resources. Use the Black-win groups.
Spassky vs Karpov, Gallagher vs Ziatdinov, Shulman vs Sulskis, Short vs Akopian, Fedorov vs Ibragimov, Fedorov vs Gyimesi, Zvjaginsev vs Tomashevsky and Zvjaginsev vs Najer show White chances. Use the White-win groups.

Hector vs Leko, Morozevich vs Kasparov, Zvjaginsev vs Akopian and Vachier-Lagrave vs Ipatov are useful elite or rapid/blitz Black examples. Use the Black-win replay groups.
No. Start with one 6.Ng1 White win, one 6.Ng1 Black win, one 4.Bc4 game and one elite Black model. Use the Replay Lab optgroups.
Look for whether White's centre arrives before Black consolidates the kingside pawn chain. Use the Adviser after each replay.
Black should play it if they want a respected accepted defense that avoids some immediate King's Gambit forcing lines. Use the Adviser with side set to Black.
White does not need to avoid it, but must know the 4.d4 g5 5.h4 g4 6.Ng1 structure and the 4.Bc4 alternatives. Use the diagram grid as your checklist.
Yes, it is practical in blitz because White often mishandles the unusual Ng1 retreat and centre timing. Use the Black-win replay group.
Yes, it has been used by elite players and remains a serious King's Gambit Accepted defense. Use the Replay Lab for model games.
It is a way for Black to avoid entering the pure Kieseritzky because ...d6 changes the knight routes and central control. Use the Branch Map to compare the Kieseritzky page.
White should prepare 4.d4, 6.Ng1, Bh6/Ne2 plans, 4.Bc4 h6, Hanstein transpositions and g3 structures. Use the diagram grid.
Black should prepare the main 4.d4 g5 line, the 4.Bc4 h6 route, ...Bg7 development and the moment to use ...f5 or ...f3. Use the Adviser.
After this page, study the King's Gambit Accepted parent, Kieseritzky Gambit, Quaade Gambit, Bishop's Gambit and King's Gambit Declined pages. Use the Branch Map links.
Use this page as the dedicated 3...d6 Fischer Defense lab. Start with the Fischer Defense Start Diagram, then compare 4.d4, ...g5, 6.Ng1, 4.Bc4 h6 and the model games.
