The Anderssen Gambit: How to Punish White's Early Aggression as Black

ECO C23 25,066 games Stockfish +1.32

White has just grabbed your b-pawn with 3.Bxb5, and now you push 3...c6 — the defining counter-thrust of the Bishop's Opening: Anderssen Gambit. This is a sharp pawn sacrifice where you give up material to seize the centre and activate your pieces with tempo. The engine rates the position +1.32, a clear advantage for White, meaning you are clearly worse here if both sides play perfectly. But the good news? Most White players don't find the best continuation. In the 25,066 games in the database, you already win 42.5% of the time as Black — the practical chances are far better than the evaluation suggests. The drill below will teach you exactly what to look for.

What the Anderssen Gambit Is Really About

After 1.e4 e5 2.Bc4, White develops a bishop to an active diagonal, threatening the classic weak f7-square. The Anderssen Gambit (2...b5) is Black's immediate, uncompromising response: you offer a pawn to chase the bishop and grab central space with ...c6. White can accept with 3.Bxb5, and after 3...c6 you are Black, having surrendered a pawn but gained a lead in development and a solid foothold in the centre. The idea is simple: your c6-pawn attacks the bishop, your d5-square is now ripe for a future ...d5 break, and your queenside pieces can come out quickly. White has to decide where to put the bishop, and as you will see, most choices are inaccurate.

The Engine's Best Move: Ba4

Stockfish's top choice is Ba4, retreating the bishop to the corner of the board. This avoids further harassment while keeping an eye on the queenside. The engine then recommends Ba4 Nf6 d3 Na6 — White intends to develop solidly and hold onto the extra pawn. This is the toughest line for you, and the engine's +1.32 reflects that White keeps a clear advantage here. In practice, though, Ba4 is played only 2,680 times out of over 25,000 games — a small minority of White players. Most club players prefer a flashier square — and that is where your winning chances jump.

The Most Popular — and Punishable — Replies

By far the most common move is Bc4 (20,467 games — the vast majority of White's choices). It looks natural: the bishop returns to its starting square, still eyeing f7. But the engine calls Bc4 an inaccuracy that loses roughly 0.7 pawns of White's advantage. Black now gets ...d5 for free — the central break you dreamed of — and your position quickly becomes active. Next is Bd3 (647 games), also an inaccuracy losing about 0.9 pawns — the bishop blocks the d-pawn and is clumsily placed. Bf1 (76 games) is a third inaccuracy, losing about 0.7 pawns, and retreats all the way home. The only two moves that avoid the 'inaccuracy' tag are Ba4 and, surprisingly, Bxc6 (25 games) — though Bxc6 sees White score just 36.0%, so it's hardly dangerous for you. The takeaway: if White plays anything other than Ba4, you are already in good practical shape.

Your Plan Against Bc4 (The Main Line)

When White plays 4.Bc4, your counter is simple and powerful: aim for ...d5 immediately. With the pawn on c6 supporting a centre push, you can challenge White's central control and open lines for your pieces. Meanwhile, your queenside bishop will have a clear diagonal on b7 or a6, and your knight can come to f6 with tempo against the e4-pawn. The statistics back this up: Black wins 42.5% overall from the starting position, but after Bc4 — the most popular choice by far — your practical chances climb even further because White has let slip the engine's precise path. The drill below will let you practise the critical moments after Bc4 and the other lesser moves, so you know exactly how to seize the initiative whenever White obliges.

Frequently asked questions

Is the Anderssen Gambit sound for Black?

Objectively, Stockfish gives the position +1.32 after 3...c6, meaning a clear advantage for White with perfect play. So the gambit is not theoretically sound — you are worse against best defence. However, in practice Black wins 42.5% of games, and White misplays the position (choosing Bc4, Bd3, or Bf1) in the vast majority of cases, giving you excellent practical chances.

What is White's best move after 3...c6 in the Anderssen Gambit?

The engine's best move is Ba4, retreating the bishop to a4. From there White plans Nf6, d3, and Na6, keeping the extra pawn. This is the only move that preserves the full advantage — all other bishop retreats (Bc4, Bd3, Bf1) are marked as inaccuracies.

Why is Bc4 a mistake for White in the Anderssen Gambit?

Bc4 is an inaccuracy that loses about 0.7 pawns of White's advantage. By returning to c4, White allows Black to play ...d5 with tempo, seizing the centre and activating the pieces. Over 20,000 games have been played after Bc4, and Black's winning chances are significantly higher than against the correct Ba4.

How does Black win after 3...c6 in this opening?

Black's main idea is to follow up with ...d5, challenging White's centre and opening lines for the bishops and knights. The pawn on c6 supports the d5 push, and Black often develops the kingside quickly — with Nf6 — while White's misplaced bishop struggles to find a good square. The statistics show Black wins 42.5% of games from the starting position.
