Sicilian Defense: Bowdler Attack with 2…Nf6 — Playing as White
After 1.e4 c5, many club players whip out 2.Bc4 hoping to catch Black off guard. But when Black answers with the spirited 2…Nf6, the game enters the Bowdler Attack: Nf6 — and the position is far sharper than a quick Scholar's Mate attempt. You've developed a piece and attacked the f7-square, but Black is already counterattacking your e4-pawn. Your next move, 3.Nc3, is solid and natural, defending the pawn while developing. Now it's Black's turn to choose their path — and the statistics reveal that some Black replies are much friendlier for you than others.

Stockfish 16 evaluates this position at -0.23, which is a very slight plus for Black. In plain terms, that means you are essentially equal out of the opening. The Bowdler Attack doesn't give White any tangible advantage if Black responds accurately — but it also doesn't leave you worse. Across a massive database of 269,437 games, White wins 50.5% of the time, Black wins 45.8%, and draws are rare at 3.7%. Those numbers tell a reassuring story: you have practical chances, and the position is perfectly playable for a club player who understands the typical plans.
The Most Popular Black Replies and Your Scores
Black has several reasonable moves here, but your winning chances vary significantly depending on which one they pick. Here's how the main options stack up for you as White: - 5…e6 (88,025 games): Black's most common — and engine-preferred — response. White scores 47.8%. This is the toughest test. - 5…Nc6 (58,090 games): White scores 49.5%, almost balanced. - 5…d6 (54,338 games): White scores 49.6%, again very close. - 5…e5 (24,863 games): White scores 57.7% — your best result by far. - 5…g6 (15,119 games): White scores 51.8%, a slight edge. - 5…a6 (14,178 games): White scores 49.7%, near parity. The takeaway: if Black plays e5 or g6, your practical results improve sharply. The next section explains why.
Two Black Mistakes You Can Punish
The engine identifies two Black moves as suboptimal — and the statistics confirm you profit from them. e5 is rated a clear mistake, losing about 1.3 pawns compared to the best move e6. g6 is an inaccuracy, costing Black roughly 0.7 pawns. If your opponent plays either of these, they've handed you an edge. After 3…e5, you have a comfortable position with a lead in development and the centre under control. After 3…g6, Black's kingside is loosened, and you can build pressure without much risk. Keep an eye out — many club players in the Bowdler Attack are trying to be tricky and may step into these inaccuracies.
The Engine's Main Line and a Typical Plan
When Black plays the best move 3…e6, the engine recommends you continue with 4.Nf3. Then after Black's natural 4…a6 (preventing Bb5 ideas), you retreat your bishop to 5.Be2. That leaves you with a solid, harmonious setup: knights on c3 and f3, bishop on e2, pawn on e4. Your plan from here is straightforward: castle kingside, build a pawn centre with d4 when possible, and develop your queen and bishops to active squares. Black's early …a6 suggests they may be aiming for …b5 expansion on the queenside. Stay alert, complete your development, and you'll reach a well-balanced middlegame with plenty of play.

Frequently asked questions
Is the Bowdler Attack (2.Bc4) a good opening for White?
It's perfectly playable at club level, but against best play — like 2…Nf6 followed by 3…e6 — White is no better than equal (Stockfish gives -0.23). The real value is that many opponents are unfamiliar with it, and you'll score well when they stumble into moves like 3…e5 or 3…g6.
What should White do after 3…e6 in the Bowdler Attack?
The engine recommends 4.Nf3, followed by …a6 5.Be2. This keeps your position solid and flexible. You can then castle, aim for d4, and develop naturally. Avoid pushing d4 too early if Black has pieces targeting the centre.
Why is 3…e5 a mistake for Black in this line?
3…e5 is a mistake because it weakens Black's control of the d5-square and leaves the d6-pawn vulnerable. The engine calculates it costs Black about 1.3 pawns. White scores 57.7% after this move in practice, so it's a good result for you.
Does the Bowdler Attack have a different ECO code?
Yes, this position falls under ECO code B20, which covers the Sicilian Defense with various early deviations by White. The Bowdler Attack (2.Bc4) is one of the most common ways to reach B20.
