Vienna Game: Max Lange Defense with Nf3 — Playing Black

The Max Lange Defense is a principled reply to the Vienna. By playing 3…Nf6, you challenge White's control of the centre immediately. You've developed a knight and attacked the e4 pawn, forcing White to decide how to handle the pressure. The resulting position is remarkably symmetrical — both sides have the same number of pieces developed, and neither has gained an obvious edge. This is the kind of opening where you play chess, not theory. Your job is to keep the balance, avoid passive moves, and wait for White to overreach. Over the next few moves, pay close attention to your king safety and central control; you have no weaknesses yet, so don't create one.

The computer's top choice here is Bb5, pinning your knight on c6. That would be followed by you playing Bd6, then d3 and a6. Notice that White pins the knight but doesn't yet double your pawns — Bxc6 would give you the b-file and the bishop pair, so White typically avoids it. Your response Bd6 develops naturally and unpins with tempo (threatening …Nxe4 in some lines). The engine sees this as perfectly equal — you have nothing to fear. In the drill, if White plays Bb5, your plan is simple: develop, keep your pawn structure flexible, and look for chances to play …d5 yourself.

While Bb5 is the engine's best move, White players at club level choose other options far more often. Here is what you can expect and how you stand: Bc4 — Played in over 11.7 million games, and White scores only 47.8%. This is great news for you. Bc4 puts a bishop on a diagonal aimed at f7, but it's often a bit hollow — you can reply …Bc5 or …d6 and start pushing for …d5. d4 — A sharp choice (7.1 million games) where White scores 52.1%, their best result. Here you need to be ready for tactical play; the main line goes 4.d4 exd4 5.Nxd4, and you can recapture with …Nxe4? (wrong) or the solid …Bb4. d3 — Played 2.8 million times but White scores only 45.6%, your best percentage. Quiet setups like d3 let you equalise easily with …Bc5 or …d5 after castling.

Among the most-played moves, Nxe5 stands out as a genuine blunder. It has been played over 800,000 times, and White scores 52.7% — but statistics hide the evaluation. The engine says Nxe5 loses roughly 2.1 pawns, and the correct move was d4. The trap: after 4.Nxe5 Nxe4, White's knight on e5 is hanging! If White tries to save it with 5.Nxe4 Qe7, you fork the knight on e5 and the e4 knight, winning a piece. Even if they see the trick, you come out with a big advantage. This is exactly the kind of mistake that makes learning this opening rewarding — when White snatches the pawn, you can strike back immediately and seize a winning position.
