Max Lange Defense Starter
Black answers the Vienna Game with 2...Nc6, the Max Lange Defense move order.
Example sequence: 1.e4 e5 2.Nc3 Nc6
The Max Lange Defense in the Vienna Game begins 1.e4 e5 2.Nc3 Nc6. This page focuses on the sharp practical branch 3.Bc4 Bc5 4.Qg4, where White attacks g7 and makes Black choose between awkward defensive concessions.
Do not confuse this with the Italian Game Max Lange Attack. Here the identity is the Vienna move order with 2...Nc6.
Choose the problem you want to solve. The adviser gives a focused plan and changes the replay selector when a supplied model game fits the diagnosis.

Black answers the Vienna Game with 2...Nc6, the Max Lange Defense move order.
Example sequence: 1.e4 e5 2.Nc3 Nc6
After 3.Bc4 Bc5, White's 4.Qg4 immediately attacks g7 and makes natural defence awkward.
Example sequence: 1.e4 e5 2.Nc3 Nc6 3.Bc4 Bc5 4.Qg4
4...Kf8 defends g7 but gives up castling rights and admits that 4.Qg4 has asked a real question.
Example sequence: 1.e4 e5 2.Nc3 Nc6 3.Bc4 Bc5 4.Qg4 Kf8
4...g6 protects the pawn but creates dark-square hooks and weakens the kingside.
Example sequence: 1.e4 e5 2.Nc3 Nc6 3.Bc4 Bc5 4.Qg4 g6
The natural 4...Qf6?? loses time to 5.Nd5! and Black's queen grab does not create enough danger.
Example sequence: 1.e4 e5 2.Nc3 Nc6 3.Bc4 Bc5 4.Qg4 Qf6 5.Nd5 Qxf2+ 6.Kd1
One immediate punishment is Qxg7+, using the advanced queen and knight on d5 to expose Black's king.
Example sequence: 1.e4 e5 2.Nc3 Nc6 3.Bc4 Bc5 4.Qg4 Qf6 5.Nd5 Qxf2+ 6.Kd1 Kf8 7.Qxg7+
White can also use Nxc7+ to fork and drag Black into a material and king-safety disaster.
Example sequence: 1.e4 e5 2.Nc3 Nc6 3.Bc4 Bc5 4.Qg4 Qf6 5.Nd5 Qxf2+ 6.Kd1 Kf8 7.Nxc7
After Nh3, d3 and c3 ideas, Black's queen can become the target rather than the attacker.
Example sequence: 1.e4 e5 2.Nc3 Nc6 3.Bc4 Bc5 4.Qg4 Qf6 5.Nd5 Qxf2+ 6.Kd1 Nh6 7.d3 Qd4 8.c3
Many real games use 3...Nf6 before ...Bc5, reaching a solid practical Max Lange Defense structure.
Example sequence: 1.e4 e5 2.Nc3 Nc6 3.Bc4 Nf6 4.d3 Bc5
...Na5 asks the c4 bishop where it belongs and often leads to doubled c-pawn or structural fights.
Example sequence: 1.e4 e5 2.Nc3 Nc6 3.Bc4 Nf6 4.d3 Na5
The same 2...Nc6 defense also allows quiet 3.g3 systems where the fight becomes positional.
Example sequence: 1.e4 e5 2.Nc3 Nc6 3.g3 Bc5 4.Bg2
White attacks g7 at once and makes the symmetrical setup uncomfortable.
Study the 4.Qg4 diagramNatural queen defence fails because 5.Nd5! makes Black's queen grab too slow.
Study the trapMany practical games avoid 3...Bc5 and use piece pressure instead.
Study the bishop chaseWhite can also turn 2...Nc6 into a quiet fianchetto battle.
Study the side branchThe selector uses supplied games only, stripped to the seven mandatory PGN tags. These model games cover practical 2...Nc6 branches around the page's 4.Qg4 focus.
Suggested route: study the 4.Qg4 diagrams first, then load one ...Nf6/...Bc5 model and one ...Na5 model.
These questions cover the exact 2...Nc6 identity, the 3.Bc4 Bc5 4.Qg4 tactical branch, Black's defensive tries, the 4...Qf6?? trap, and the supplied practical replay set.
The Max Lange Defense is the Vienna Game reply 1.e4 e5 2.Nc3 Nc6. It is a broad second-move defence, but this page focuses on the important 3.Bc4 Bc5 4.Qg4 Symmetrical Variation because that is where the move order becomes immediately awkward. Start with the Max Lange Defense Starter diagram before opening the 4.Qg4 lab.
No. The Vienna Game Max Lange Defense is 1.e4 e5 2.Nc3 Nc6, while the famous Max Lange Attack belongs to Italian Game and Two Knights style positions. This page keeps the Vienna naming clear by using the 2...Nc6 move order and the 3.Bc4 Bc5 4.Qg4 branch. Use the Starter diagram to avoid mixing the two openings.
It deserves its own page because 2...Nc6 is a major Vienna Game crossroads and 3.Bc4 Bc5 4.Qg4 creates a distinctive practical problem. The page is not just a generic 2...Nc6 page; it explains the awkward queen pressure, the defensive tries, and the real-game side branches. Use the Branch Map to move from the identity to the concrete 4.Qg4 test.
The main featured line is 1.e4 e5 2.Nc3 Nc6 3.Bc4 Bc5 4.Qg4. White attacks g7 immediately and asks Black to choose between unattractive defences such as 4...Kf8 and 4...g6. Study the Symmetrical 4.Qg4 diagram first.
It is called symmetrical because both bishops develop to the c-file diagonals, with White's bishop on c4 and Black's on c5. The symmetry does not last long because White's 4.Qg4 attacks g7 and forces Black to react. Use the Symmetrical 4.Qg4 diagram to see how quickly the balance changes.
Black does not have to play 3...Bc5 after 3.Bc4. In practice, many games use 3...Nf6, followed by ...Bc5, ...Na5, or quieter development. Use the Practical 3...Nf6 Main Line diagram to compare the common practical route with the sharper 3...Bc5 4.Qg4 test.
4.Qg4 is awkward because it attacks g7 while White's bishop on c4 also points toward f7. Black can defend, but the natural-looking moves all carry a cost. Use the Symmetrical 4.Qg4 diagram and then compare the 4...Kf8 and 4...g6 diagrams.
Black's best practical tries are usually 4...Kf8 and 4...g6. Neither is completely comfortable: 4...Kf8 gives up castling rights, while 4...g6 creates dark-square weaknesses. Use the Best Try: 4...Kf8 and Best Try: 4...g6 diagrams to choose the style you prefer.
4...Kf8 is playable because it directly defends g7 and avoids the tactical problems of 4...Qf6. The price is that Black's king stays awkward and castling is no longer available. Use the Best Try: 4...Kf8 diagram to remember the practical tradeoff.
4...g6 is playable because it protects g7 without moving the king. The drawback is that Black weakens dark squares and creates hooks for White's queen and bishop. Use the Best Try: 4...g6 diagram to see the permanent kingside concession.
4...Qf6 loses tactically because 5.Nd5! hits the queen and creates threats after 5...Qxf2+ 6.Kd1. White's king is not in real danger, while Black must face Qxg7, Nxc7+ and queen-trap ideas. Use the 4...Qf6?? Trap diagram before playing natural queen defence.
White is safer than it looks because Black's queen has wandered to f2 while White's pieces create concrete threats. The king on d1 is exposed, but Black does not have enough developed force to exploit it immediately. Use the Qxg7+ and Nxc7+ threat diagrams to see why White can ignore the queen check.
White's main threats are Qxg7, Nxc7+, and Nh3 with d3 and c3 ideas to trap or harass Black's queen. The key is that the knight on d5 controls important squares while the queen attacks g7. Use the Threat: Qxg7+, Threat: Nxc7+ and Queen-Trap Net diagrams in order.
After 3.Bc4 Bc5 4.Qg4, 4...Nf6 does not directly solve the attack on g7. That is why the page highlights 4...Kf8 and 4...g6 as the main practical tries. Use the Symmetrical 4.Qg4 diagram and name the g7 problem before choosing a defence.
After 3...Nf6, White often plays 4.d3 and Black can still develop with ...Bc5 or chase the bishop with ...Na5. These positions are less immediately tactical than 4.Qg4 but occur frequently in real games. Use the Practical 3...Nf6 Main Line and Na5 Bishop Chase diagrams.
Black plays ...Na5 to challenge the bishop on c4 and reduce White's pressure on f7. The move can gain time, but it may also lead to structural concessions after captures on c4. Use the Na5 Bishop Chase diagram before replaying Mamedyarov (White) vs Aronian (Black).
White should decide whether the c4 bishop is worth preserving or whether structural play after dxc4 is acceptable. The choice depends on development, castling and whether White can create pressure on the centre or queenside. Use the Na5 Bishop Chase diagram and replay Sax (White) vs Smejkal (Black).
White can play 3.g3 against 2...Nc6, steering into quiet fianchetto Vienna positions. Those lines are not the main 4.Qg4 focus, but they are useful side branches for players who want a lower-tactics option. Use the 3.g3 Side Branch diagram and replay Spassky (White) vs Nikolic (Black).
White can play 3.f4 after 2...Nc6, entering the strict Vienna Gambit family. That branch is different from the 3.Bc4 Bc5 4.Qg4 focus and should be studied separately if you want gambit play. Use the Branch Map here, then move to your Vienna Gambit page for 3.f4 details.
2...Nc6 is a sound reply, but it is not a shortcut to safety. White can choose 3.f4, 3.Bc4, 3.g3 or 3.Nf3, and each asks a different question. Use the Max Lange Adviser to choose whether you need the 4.Qg4 tactic, the ...Na5 structure, or the 3.g3 side branch first.
3.Bc4 Bc5 still sees play, but Black must know what to do after 4.Qg4. If Black drifts into 4...Qf6??, the position can collapse quickly. Use the 4...Qf6?? Trap diagram before trusting the symmetrical setup.
Black avoids the trap by not meeting 4.Qg4 with 4...Qf6. The safer practical choices are 4...Kf8 or 4...g6, with clear acceptance of the resulting concession. Use the Black-side safety recommendation in the adviser to rehearse both diagrams.
Start with Sax (White) vs Smejkal (Black) if you want a practical 3...Nf6 and ...Bc5 model. It shows a real Max Lange Defense structure where Black later wins through central and kingside pressure. Load Sax (White) vs Smejkal (Black) in the Interactive Max Lange Defense Replay Lab.
Balashov (White) vs Smejkal (Black) is a good White model against the ...Nf6 and ...Bc5 structure. White develops, uses Nd5 and c3-d4 ideas, and turns the centre into activity. Load Balashov (White) vs Smejkal (Black) after the Practical 3...Nf6 Main Line diagram.
Mamedyarov (White) vs Aronian (Black) shows the ...Na5 bishop chase in elite practice. Black removes the c4 bishop and later wins with tactical pressure. Load Mamedyarov (White) vs Aronian (Black) after reviewing the Na5 Bishop Chase diagram.
Spassky (White) vs Nikolic (Black) is a useful 3.g3 side-branch model after 2...Nc6. It shows that the Max Lange Defense move order can become a slower fianchetto struggle rather than a 4.Qg4 tactic. Load Spassky (White) vs Nikolic (Black) from the side-branch replay group.
Lu Shanglei (White) vs Carlsen (Black) is a modern blitz fight from the 3.g3 Bc5 branch. It is not the 4.Qg4 line, but it shows how sharp the broader 2...Nc6 family can become. Load Lu (White) vs Carlsen (Black) after the 3.g3 Side Branch diagram.
Study one decision point at a time: first 2...Nc6, then 3.Bc4 Bc5 4.Qg4, then the 4...Qf6?? trap, then the practical ...Nf6 and ...Na5 games. Do not mix the Max Lange Defense with the Max Lange Attack. Use the adviser to pick the exact next diagram or replay.
Remember that the Vienna Game Max Lange Defense is 2...Nc6, but the page's tactical core is 3.Bc4 Bc5 4.Qg4. Black's natural 4...Qf6?? fails to 5.Nd5! and White's threats are stronger than the queen check. Start with the 4...Qf6?? Trap diagram.
No, this page does not replace the Vienna Gambit page. The Vienna Gambit is 1.e4 e5 2.Nc3 Nc6 3.f4, while this page focuses on 3.Bc4 Bc5 4.Qg4 and related Max Lange Defense branches. Use the Branch Map to decide which Vienna child page to study next.
4.Qg4 is not just a cheap trick because it asks Black to solve a genuine g7 problem. The trap works only against careless defence, but even the best replies leave Black with some concession. Use the 4.Qg4 and defensive-try diagrams before dismissing the move.
White's king on d1 is not permanently safe, but in the 4...Qf6?? line Black lacks enough development to exploit it immediately. That is why White's threats against g7, c7 and the queen matter more. Use the 4...Qf6?? Trap diagram and then check the Qxg7+ and Nxc7+ follow-ups.
In the featured line after 3.Bc4 Bc5 4.Qg4, 4...Qf6 is a tactical mistake because of 5.Nd5. The point is not that queen development is always bad, but that this exact square loses time against White's knight jump. Use the trap diagram before playing ...Qf6 by pattern.
No, the Max Lange Defense begins at 2...Nc6 and includes many White third moves. This page gives 4.Qg4 pride of place because it is the branch with the clearest independent reason to study the page. Use the replay selector to see broader 2...Nc6 practice.
White's biggest mistake is playing Qg4 without knowing the concrete follow-up after each Black defence. If Black chooses 4...Kf8 or 4...g6, White still needs a normal development plan. Use the Max Lange Adviser and select I only know the trap for the next step.
Black's biggest mistake is defending g7 with a natural-looking queen move and missing 5.Nd5. The second biggest mistake is assuming 3.Bc4 Bc5 is symmetrical and therefore harmless. Use the 4...Qf6?? Trap diagram before playing the symmetrical branch.
The line can work well in blitz because 4.Qg4 creates immediate practical discomfort. It works best when you know the follow-up threats without needing to calculate from scratch. Use the Blitz trap route in the adviser and then load one practical replay to avoid becoming trap-only.
The line can be used in classical games, but the trap alone is not enough. Strong players will choose 4...Kf8 or 4...g6 and ask White to prove a full position. Use the Best Try diagrams and the Balashov replay to build a more serious study path.
The Max Lange Defense is useful because it forces a choice: 4.Qg4 tactics, ...Nf6 development, ...Na5 bishop questions, or quiet 3.g3 structures. Learn the trap, then learn the full map.
