Bishop's Opening: Philidor Counterattack – How Black Strikes Back

The whole point of the Philidor Counterattack is to challenge White's centre immediately. By playing 2...c6 and 3...d5, Black targets White's e4 pawn and asks the bishop on c4 a question: where will it go? Unlike passive systems where Black just develops, you are creating tension in the centre from move three. If White captures on d5 (the most common response, seen in 581,743 games), you recapture with the c-pawn and open lines for your pieces. Your queen's knight gets c6, the light-squared bishop goes to f5 or g4, and you have a solid, active position. The resulting pawn structure — White often ends up with a pawn on e5 against your d5 pawn — gives you clear targets and a straightforward plan of piece development.

Stockfish's top choice for White is 4.Bb3, retreating the bishop to safety before Black can capture it with ...dxe4. After 4.Bb3 Nf6 5.Nc3 Bd6, the game takes on a slower, more strategic character. White keeps the bishop pair but has lost a tempo by moving the bishop twice. From Black's perspective, this is a comfortable and balanced position. You have active development, control of d5, and no weaknesses. The key is not to rush — finish your development, castle kingside, and then decide whether to push ...d4 or keep the tension. Because White's bishop on b3 is aiming at your f7 square, stay alert to tactical ideas, but don't be intimidated; the position offers equal chances.

Many White players, especially at club level, make inaccurate moves here. Three specific errors stand out in the data, and you should know how to exploit each one: - 4.Bd3 (a mistake worth ~2.6 pawns): This retreat blocks White's own d-pawn and weakens control of the centre. You can simply capture on e4, or develop with tempo like ...Nf6 followed by ...dxe4. - 4.d3 (a blunder, losing ~3.9 pawns): White plays too passively, allowing you to take over the centre. Capturing on e4 is strong, or you can develop rapidly with ...Nf6 and ...Bd6. - 4.O-O (a blunder, losing ~3.2 pawns): Castling immediately is a trap. You can take on e4 (the d-pawn is pinned to the queen on d8 along the d-file), winning a pawn cleanly. Watch for these — if your opponent plays any of them, you should emerge with a clear advantage.

The most common move by far is 4.exd5, played in 581,743 of the 615,716 games. After you recapture with ...cxd5, White scores 48.8% — essentially equal. This tells you that even the main line offers Black excellent practical chances. Meanwhile, the retreat 4.Bb3 — the engine's preferred move — only appears in 21,000 games and sees White scoring 51.9%. That's still a very modest plus for White in a line that many opponents won't even know. The real opportunities come when White picks a poor move: after 4.Bd3 White scores only 42.5%, after 4.O-O just 34.6%, and after 4.d3 a miserable 29.1%. So by learning this opening as Black, you're not just playing a solid line — you're setting a trap that many White players will stumble into.
