King's Indian Hungarian Attack: Adviser, Diagrams and Replay Lab

The King's Indian Hungarian Attack is White's Nge2 and Ng3 system against the King's Indian Defence, usually after d4, c4, Nc3 and e4. The defining feature is the knight route from g1 to e2 and then g3 rather than the more common Nf3 development. Use the Hungarian Attack start diagram.

A clean move order is 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nge2 O-O 6.Ng3. This move order is the practical branch marker because it reaches the knight route before Black’s main counterplay choices are fixed. Use the Hungarian Attack start diagram.

White plays Nge2 and Ng3 to support e4, keep the f-pawn flexible, and aim pressure at dark squares and the kingside. The route changes the usual King’s Indian battle because the f-pawn stays free and the g3 knight can support kingside pressure. Use the Hungarian Attack start diagram.

Yes. The classification is based on White’s anti-King’s Indian setup, not on a separate opening family. Use the Branch Map.

White wants a flexible centre, kingside space with h4 or f4, and pressure against Black's dark squares. The plan works best when the knight route is connected to a concrete central or kingside follow-up. Use the Adviser with side set to White.

Black tries to exploit the knight on g3 with ...h5, challenge the centre with ...e5 or ...c5, and create queenside counterplay with ...a6 or ...b5. Black’s counterplay is strongest when it challenges the centre before White converts the g3 knight into attacking pressure. Use the Adviser with side set to Black.

Yes. The sharpness comes from the tension between White’s kingside build-up and Black’s central or queenside breaks. Use the Replay Lab.

Yes, if White understands why the knight goes to g3 and does not let it become a target. Its practical value is that the structure is unusual enough to create decisions without requiring the deepest main-line memory. Use the diagram grid.

White usually plays d4, c4, Nc3, e4, Nge2 and Ng3, then chooses Be2, Bg5, h4, f3 or f4. The key practical point is to connect the move order with the pawn structure it creates. Use the Hungarian Attack start diagram.

Be2 supports castling and keeps White flexible before choosing Bg5, h4, f4 or central play. Be2 keeps the king flexible and lets White decide later between castling, Bg5, h4 and f4 plans. Use the ...a5 and ...Na6 diagram.

Bg5 pressures Black's normal King's Indian setup and often combines with h4 and Qd2 ideas. The bishop move gains value because it makes Black’s normal kingside and central coordination less automatic. Use the Bg5 setup diagram.

White plays h4 to stop or meet Black's ...h5, gain kingside space, and prepare attacking play. The h-pawn battle matters because Black’s ...h5 can make the g3 knight either powerful or misplaced. Use the ...h5 plan diagram.

White plays f4 when the centre is locked or stable enough for kingside expansion without losing e4. The plan works best when the knight route is connected to a concrete central or kingside follow-up. Use the Replay Lab's kingside games.

White castles queenside when the centre is closed and White wants a direct kingside attack with h4, g4 or f4. The plan works best when the knight route is connected to a concrete central or kingside follow-up. Use the Replay Lab.

Be2 plus Bg5 or h4 is practical because it develops quickly while keeping the attacking plan clear. The key practical point is to connect the move order with the pawn structure it creates. Use the Adviser.

White should only push h4, f4 or g4 when Black's central counterplay is under control. The plan works best when the knight route is connected to a concrete central or kingside follow-up. Use the Adviser with problem set to overextension.

...e5 challenges the centre and often leads to d5 structures where Black can use ...a5, ...Na6 or ...Nc5. The ...e5 break is a core King’s Indian test because it asks whether White’s centre should close or remain tense. Use the ...e5 and d5 diagram.

...a5 and ...Na6 give Black queenside control and a route to c5 before White's kingside attack becomes dangerous. This manoeuvre gives Black queenside control and a clear route for the knight toward c5. Use the ...a5 and ...Na6 diagram.

...h5 questions the knight on g3, grabs dark squares, and can prevent White from using h4 freely. This is especially relevant because the knight on g3 and the h4 square are both sensitive targets. Use the ...h5 plan diagram.

...c5 attacks White's centre before the Nge2-Ng3 attacking setup is fully ready. The ...c5 and ...e6 plan changes the game into a space-versus-counterplay structure similar to Benoni play. Use the ...c5/e6 Benoni structure diagram.

The game can become a Benoni-style fight where White has space and Black has dynamic breaks. The ...c5 and ...e6 plan changes the game into a space-versus-counterplay structure similar to Benoni play. Use the ...c5/e6 Benoni structure diagram.

Black builds queenside counterplay and attacks c4 before White's kingside plan lands. Queenside expansion is effective only when Black can hit c4 before White’s kingside pressure becomes decisive. Use the ...c6, ...a6 and ...b5 diagram.

...Qe8 supports ...h5, ...Nh7, ...f5 or kingside pressure against White's g3 knight. The queen move is useful because it supports several kingside and central plans without committing the pawn structure immediately. Use the Replay Lab's Bg5 and ...Qe8 group.

...e5 with ...a5/...Na6 and ...c5 with ...e6 are the most practical because they hit the centre and restrict White's slow build-up. The key practical point is to connect the move order with the pawn structure it creates. Use the Adviser.

White should use Nge2-Ng3 to support the centre, then choose between Be2, Bg5, h4, f4 and castling choices based on Black's counter. The plan works best when the knight route is connected to a concrete central or kingside follow-up. Use the Adviser with side set to White.

White should play h4 when it stops Black's ...h5 or supports a direct kingside expansion without weakening the centre. The plan works best when the knight route is connected to a concrete central or kingside follow-up. Use the ...h5 plan diagram.

White should play Bg5 when the pin or pressure makes Black's ...e5, ...h5 or ...Qe8 decisions awkward. The plan works best when the knight route is connected to a concrete central or kingside follow-up. Use the Bg5 setup diagram.

White should play d5 when the space gain restricts Black's pieces and supports a kingside plan. The plan works best when the knight route is connected to a concrete central or kingside follow-up. Use the ...e5 and d5 diagram.

White plays Be3 when they want to support d4, prepare Qd2 and keep queenside castling or kingside expansion available. The plan works best when the knight route is connected to a concrete central or kingside follow-up. Use the Replay Lab's Be3 group.

White should avoid placing the knight on g3 and then allowing ...h5, ...h4 or central breaks without a response. The plan works best when the knight route is connected to a concrete central or kingside follow-up. Use the Adviser with problem set to knight safety.

White's biggest mistake is treating Nge2-Ng3 as automatic; the setup needs a clear follow-up such as Bg5, h4, f4 or d5. The underlying danger is that a flexible setup becomes passive if it is not connected to a timed pawn break. Use the diagram grid.

White should study one ...e5/d5 game, one ...h5 game, one ...c5/e6 game and one Bg5 attacking game. The plan works best when the knight route is connected to a concrete central or kingside follow-up. Use the Replay Lab optgroups.

Black should challenge the centre quickly and make the g3 knight prove itself with ...h5, ...e5, ...c5 or ...b5. Black’s counterplay is strongest when it challenges the centre before White converts the g3 knight into attacking pressure. Use the Adviser with side set to Black.

Black should play ...e5 when they can force d5 or central tension without giving White an easy attack. Black’s counterplay is strongest when it challenges the centre before White converts the g3 knight into attacking pressure. Use the ...e5 and d5 diagram.

Black should play ...h5 when the g3 knight and h4 advance can be challenged before White consolidates. Black’s counterplay is strongest when it challenges the centre before White converts the g3 knight into attacking pressure. Use the ...h5 plan diagram.

Black should play ...c5 when White's centre needs immediate pressure and Black is ready for Benoni-style structures. Black’s counterplay is strongest when it challenges the centre before White converts the g3 knight into attacking pressure. Use the ...c5/e6 Benoni structure diagram.

Black should play ...a6 and ...b5 when the queenside can be opened before White's kingside attack becomes decisive. Black’s counterplay is strongest when it challenges the centre before White converts the g3 knight into attacking pressure. Use the ...c6, ...a6 and ...b5 diagram.

Black uses ...Qe8 when the queen supports ...h5, ...Nh7, ...f5 or pressure against the kingside. Black’s counterplay is strongest when it challenges the centre before White converts the g3 knight into attacking pressure. Use the Replay Lab's ...Qe8 group.

Black's biggest mistake is letting White build Nge2, Ng3, h4, Bg5 and f4 without central counterplay. The underlying danger is that a flexible setup becomes passive if it is not connected to a timed pawn break. Use the Adviser with problem set to counterplay.

Black should study one ...e5/...Na6 model, one ...h5 model, one ...c5/e6 model and one Black counterattack win. Black’s counterplay is strongest when it challenges the centre before White converts the g3 knight into attacking pressure. Use the Replay Lab.

Start with Rohde vs Polgar for the ...e5, d5 and ...Na6 structure, then compare Lutz vs Gelfand for the h-pawn race. The key practical point is to connect the move order with the pawn structure it creates. Use the Replay Lab selector.

Rohde vs Polgar, Lutz vs Gelfand, Bauer vs Degraeve, Tregubov vs Volokitin, Bologan vs Kovalev and Carlsen vs Radjabov show ...e5, d5 and ...Na6 or related structures. The ...e5 break is a core King’s Indian test because it asks whether White’s centre should close or remain tense. Use the ...e5/d5 replay groups.

Bareev vs Kazhgaleyev, Tregubov vs Guseinov, Tregubov vs Kempinski, Bologan vs Solak and Bologan vs Mamedov show ...c5 and ...e6 structures. The ...c5 and ...e6 plan changes the game into a space-versus-counterplay structure similar to Benoni play. Use the ...c5/e6 replay groups.

Sokolov vs Hjartarson and Ponomariov vs Bologan show ...c6, ...a6 and ...b5 counterplay structures. Queenside expansion is effective only when Black can hit c4 before White’s kingside pressure becomes decisive. Use the ...c6/...b5 replay group.

Lutz vs Gelfand, Rohde vs Polgar, Serper vs Shabalov, Volokitin vs Tregubov, Bologan vs Mamedov and Carlsen vs Radjabov show h-pawn and dark-square themes. The h-pawn battle matters because Black’s ...h5 can make the g3 knight either powerful or misplaced. Use the h-pawn replay groups.

Sokolov vs Hjartarson, Bauer vs Degraeve, Tregubov vs Guseinov, Ponomariov vs Bologan and Bologan vs Solak show White resources in the supplied set. Model games are useful here because the same knight route can lead to very different pawn structures. Use the White-result replay groups.

Rohde vs Polgar, Lutz vs Gelfand, Serper vs Shabalov, Bareev vs Kazhgaleyev, Tregubov vs Kempinski, Volokitin vs Tregubov, Bologan vs Mamedov, Rapport vs Ding, Anton Guijarro vs Smirin, Carlsen vs Radjabov and Bologan vs Kovalev show Black resources. Model games are useful here because the same knight route can lead to very different pawn structures. Use the Black-result replay groups.

No. Model games are useful here because the same knight route can lead to very different pawn structures. Use the Replay Lab optgroups.

White should play it if they want a flexible anti-King's Indian system that avoids normal Nf3 patterns and creates kingside pressure. The plan works best when the knight route is connected to a concrete central or kingside follow-up. Use the Adviser with side set to White.

Black should respect it but not fear it. Black’s counterplay is strongest when it challenges the centre before White converts the g3 knight into attacking pressure. Use the Adviser with side set to Black.

No. The classification is based on White’s anti-King’s Indian setup, not on a separate opening family. Use the Branch Map.

Yes, because Be2 and Bg5 ideas can overlap, but the Hungarian Attack adds the Nge2-Ng3 knight route. The classification is based on White’s anti-King’s Indian setup, not on a separate opening family. Use the Branch Map.

Yes, because it creates unusual practical problems, especially around the g3 knight, h-pawns and dark squares. Its practical value is that the structure is unusual enough to create decisions without requiring the deepest main-line memory. Use the Replay Lab.

After this page, study the Makogonov System, Averbakh Variation, Sämisch Variation, Four Pawns Attack and Fianchetto Variation. The best follow-up is to compare systems that share the same King’s Indian pawn breaks but use different piece setups. Use the Branch Map links.

Use one diagram to learn Nge2-Ng3, one Adviser recommendation to choose a plan, and one Replay Lab group to see that plan in action. This works because the page links each plan to a visual position and a replay group rather than leaving the idea abstract. Use the Adviser first.

Learn 5.Nge2 and 6.Ng3, then compare ...e5/d5, ...h5, ...c5/e6 and Bg5 systems. The fastest learning route is structural: recognise the knight placement first, then attach the correct pawn-break response. Use the diagram grid first.
