How to Play the Nimzowitsch Defense: Brandics Gambit
You've stepped into a rare but feisty opening: after 1.e4 Nc6 2.d4 d5 3.Nc3 a6, you've entered the Nimzowitsch Defense: Scandinavian Variation, Bogoljubow Variation, Brandics Gambit. The board is unbalanced, and your opponent already faces a choice that will define the fight. Statistically, 4,590 games have reached this exact position, with Black winning 44.9% of them — respectable for a sharp sideline. But the engine sees things differently: Stockfish rates this +1.06, a clear edge for White, so you are worse here. Your task is to understand where that evaluation comes from, which White moves are genuinely dangerous, and which ones you can punish. The interactive drill below will put you in the hot seat as Black, letting you test your responses against an adapting engine.

The move 3...a6 is the heart of the Brandics Gambit. It looks modest, but it serves two important purposes. First, it prevents White from playing Nb5 after a future ...dxe4 — a common nuisance when Black's knight sits on c6. Second, it prepares ...b5, gaining queenside space and potentially chasing away White's light-squared bishop. In return, White gets a head start on development and central control. The engine's evaluation (+1.06) reflects that White's centre is still intact and his pieces are free to deploy aggressively. As Black, you are not trying to equalise out of the opening; you are aiming to create imbalances and steer the game toward positions where your extra queenside space and piece activity can compensate for the slight deficit.
The Critical Reply: exd5
The most common move in the database is 4.exd5, appearing in 2,324 games. It is also the engine's top choice and the only move that keeps White's advantage solid. After 4.exd5, the standard continuation is 4...Nb4 5.Bc4 Nf6 — your knight jumps to b4, eyeing c2, while your other knight develops and attacks the d5 pawn. White scores 54.6% from this line, but Black still wins 44.9% of those games, so there is plenty of play. Your plan here is to keep pressure on the centre, finish development, and eventually undermine White's d5 pawn with moves like ...c6 or ...Bf5. Be alert for tactics around the c2-square — that is your main source of counterplay.
When White Plays a Weaker Move
Several alternatives to exd5 are popular but statistically weaker. Here are the three mistakes the engine flags (all losing roughly 0.6–0.8 pawns compared to exd5): – e5 (700 games, White scores 52.0%): This block looks natural but lets you dissolve the centre with ...f6 or ...c5. White's score drops slightly, and the engine considers it an inaccuracy. – Nxd5 (431 games, White scores 45.7%): White takes the pawn but walks into 4...Nxd5, when after 5.Nxd5 Qxd5 you have a comfortable position with the bishop pair and easy development. Black actually scores 54.3% here — a real chance to take over. – Be3 (170 games, White scores 51.8%): A developing move that does nothing to clarify the centre. You can reply ...dxe4 or ...Nf6 and enjoy easy equality. Notice that Nf3 (506 games, White scores just 46.0%) and Bf4 (138 games, White scores 46.4%) are actually slightly worse for White statistically — so if your opponent picks one of those, you already have the upper hand.
What the Statistics Tell You
From the 4,590-game sample, White's overall winning percentage is 51.7% and Black's is 44.9%. Those numbers are remarkably close for a position the engine considers clearly better for White (+1.06). The explanation is that many White players do not know the precise response (exd5) and instead play one of the inaccuracies listed above. When White chooses exd5, their score jumps to 54.6% — still not crushing, because Black has real counterplay. When White chooses Nxd5 or Nf3, their score drops below 46%, meaning Black scores over 54%. Your practical chances are excellent as long as you know how to handle the main line with 4.exd5 Nb4 5.Bc4 Nf6. The drill below will help you build that exact skill.

Frequently asked questions
Is the Brandics Gambit sound for Black?
The engine gives +1.06, so objectively White is clearly better with best play. However, Black's 44.9% win rate across 4,590 games shows that in practical play it is perfectly viable, especially because many White players do not find the critical 4.exd5 response.
How should Black respond to 4.exd5 in the Brandics Gambit?
The standard reply is 4...Nb4, threatening Nc2+, followed by 5.Bc4 Nf6. Your knight on b4 creates tactical threats around the c2-square, while the other knight develops and attacks the d5 pawn. This is the main line you should practise.
What are the biggest mistakes White can make here?
The engine flags 4.e5, 4.Nxd5, and 4.Be3 as inaccuracies, each costing White roughly 0.6–0.8 pawns. After 4.Nxd5 you can recapture with the knight and achieve a comfortable position; after 4.e5 you have ...f6 or ...c5 to fight back immediately.
What is Black's typical middlegame plan after 4.exd5 Nb4 5.Bc4 Nf6?
You aim to complete development (Bf5, e6, Be7, O-O), keep pressure on the d5 pawn, and exploit the knight on b4 to create threats against c2. Queenside expansion with ...b5 and ...c5 is also a common plan to challenge White's centre.
