English Opening: King's English Variation, Reversed Sicilian Nf6 — Playing as White
After 1.c4 e5 2.Nc3 Nf6 3.Nf3, you've reached a famous crossroads. This is the Reversed Sicilian — you're playing a Sicilian Defence a tempo up, but Black has already challenged your centre with …Nf6. The engine sees this as dead level (+0.15), a small edge for White so small it's practically equal. But the statistics across millions of games tell a different story: you win 53.6% of the time from here, while Black wins only 42.5%. That edge is real, and it comes from knowing what to do against Black's most common replies. Below, you'll find the engine's best line, the mistakes to punish, and exactly how to handle whatever Black throws at you.

This position is a battle for central influence. White has played c4, Nc3, and Nf3 — you've developed toward the centre without committing the d-pawn yet. Black's last move, …Nf6, pressures e4 and prepares …d5 or …Bc5 ideas. Your main long-term trumps are the extra tempo compared to a standard Sicilian (where Black plays …c5) and the flexibility to choose between d4, g3, or a slow build-up. The statistics show you win 53.6% of the time — not because you're winning out of the opening, but because White's extra space and safer king tend to pay off in the middlegame. Your job is to develop naturally, keep the centre resilient, and wait for Black to overextend.
The Engine's Top Move: Black Plays Nc6
In response to your 3.Nf3, Stockfish rates Nc6 as Black's best continuation (618,533 games, the most popular reply). The engine's preferred line runs: Nc6 a3 d5 cxd5. Black develops the knight, you play a3 (stopping …Bb4 and preparing b4 or e3), Black strikes in the centre with …d5, and you capture. The resulting positions are balanced but comfortable — your structure is solid, Black's knight on f6 can be a target, and you have easy development. Your winning percentage against Nc6 is 52.1%, a slight edge you can build on with accurate play.
Three Mistakes Black Makes Most Often
The FACTS list three clear mistakes from this position — and each one gives you a chance to grab an advantage right away. Here they are, ordered by how often they appear on the board: Bc5 (118,629 games, loses ~1.4 pawns), Bb4 (112,073 games, loses ~1.1 pawns), and d5 (62,311 games, loses ~1.4 pawns). In each case, Nc6 would have been better. When Black plays …Bc5, the bishop is exposed and you can immediately apply pressure on the e5-pawn with active piece play. Against …Bb4, the pin is premature and a calm developing move gives you a comfortable edge. And …d5? Your c-pawn is already on c4, so cxd5 gives you a comfortable IQP position with lead in development. Learn to spot these moments and your score will climb well above 56%.
The Popular Move e4 — an Early Blow
Black plays e4 124,041 times (your best winning percentage among the top replies: 56.3%). Yes — Black pushes the pawn your knight attacks! After 3…e4, the knight retreats to safety and you maintain a pleasant edge. The key is that Black has spent a tempo pushing a pawn that doesn't threaten your king and has weakened the d4 square permanently. Your plan is simple: develop naturally, keep pieces active, and enjoy the extra time. Your opponents will often regret this pawn push when their centre becomes a target.

What is Black's best move after 1.c4 e5 2.Nc3 Nf6 3.Nf3?

Is Bc5 a mistake in the Reversed Sicilian Nf6?
Yes — Bc5 is listed as a mistake costing about 1.4 pawns. The better move was Nc6. If Black plays Bc5, the bishop is exposed and active piece play immediately creates threats the bishop cannot handle.
How should White respond to Black playing e4 on move 4?
