Facing the English Opening: f5 — A Black Repertoire Guide
The English Opening: f5 (1.c4 f5) is a bold way for White to avoid main-line theory and steer the game into Dutch-like territory. After 2.d4, you're already at a crossroads. The position looks innocent, but the statistics and the engine agree: one move is clearly best, and another is a common pitfall that gives White a serious edge. Let's look at what the numbers say, why the engine prefers a specific reply, and how you can walk away from this opening with a perfectly playable middlegame – as long as you avoid the biggest mistake. The interactive drill below will let you test these ideas against a live engine.

You're playing Black against a flank opening that aims to control the centre from the side. White's d4 push stakes a clear claim to the centre, which you've already challenged with ...f5, a Dutch-style setup. Your immediate job is simple: develop naturally without weakening your position. The engine evaluates the position at +0.61, a small edge for White, meaning you're slightly worse out of the opening but nowhere near lost. Across over 3.5 million games, White wins 49.7%, Black wins 46.6%, and only 3.7% end in draws — a practical fighting position where you can absolutely compete. The key is picking the right response here, because one popular move drops the evaluation significantly.
The Engine's Choice: e6
Stockfish's top recommendation is e6, planning to continue with ...g6, ...Nf6, and ...Bg2 (the engine line being e6 g3 Nf6 Bg2). This flexible move opens lines for your light-squared bishop, prepares to challenge White's centre with ...d5 or ...c5, and keeps your kingside structure intact. It's also the second-most popular move in practice, played in over 668,000 games, and White scores just 48.8% against it — statistically your best result. By choosing e6, you steer the game toward a solid, manoeuvring middlegame where White's small theoretical edge requires precise play to maintain.
The Numbers on Each Black Reply
Here's how White scores against Black's most common moves from this position, based on millions of games. Lower White scores are better for you. - Nf6 (2,474,783 games — by far the most popular): White scores 49.0% — a solid, playable response. - e6 (668,749 games): White scores 48.8% — the best practical result for Black, and the engine's top pick. - g6 (138,801 games): White scores 50.5% — slightly worse for Black than e6 or Nf6. - d6 (92,544 games): White scores 53.5% — noticeably better for White. - c6 (42,747 games): White scores 51.3% — okay but not optimal. As you can see, Nf6 and e6 are the only replies that keep White's score below 49%. While Nf6 is more popular, e6 scores even better — a strong argument for making it your first-choice reply.
The One Move You Should Avoid: d5
The clearest takeaway from the data is that d5 is a genuine mistake. It's been played in over 65,000 games, but White scores 58.2% — the worst outcome for Black by a wide margin. The engine confirms this as an inaccuracy, costing you roughly 0.8 pawns compared to the best move (e6). Why is d5 so bad? You're challenging the centre directly, but White can reply with cxd5 (or even Nc3, pressuring your d5 pawn). Your pawn on f5 becomes weak, your dark-squared bishop is blocked, and White gets a comfortable plus. It's a natural-looking move that the statistics reveal as a trap. Always choose e6 or Nf6 instead.
