Sicilian Defense: Najdorf Variation, English Attack: what should Black play?

In the Sicilian Defense: Najdorf Variation, English Attack (ECO B90), Black's most critical decision centers on how to counter White's intended kingside pawn storm. While the vast majority of games continue with central expansion, engine analysis narrowly favors Ng4 (evaluated at +0.30), which immediately disrupts White's development by harassing the dark-squared bishop on e3. Black also regularly relies on e5 and e6 to contest key central squares before White consolidates.

Harassing the Bishop with Ng4

Although played in only 7.5% of recorded games (318K recorded), Ng4 yields the lowest scoring rate for White among all major tries, with White scoring 46.7%. By targeting the e3, Black exploits White's decision to omit an early h2-h3 or f2-f3. An illustrative engine continuation demonstrates how White must concede tempo: Ng4 Bc1 Nf6 h3 e6 g4. Black retreats the knight after forcing the bishop back to c1, successfully delaying White's setup on the kingside.

Classical Central Strikes: e5 and e6

The most common response is e5, appearing in 57.5% of games (2.43M recorded) with an evaluation of +0.31. Against this, an illustrative line runs e5 Nb3 Be6 h3 Nbd7 g4, leading to classic Sicilian structures where White scores 49.7%. Alternatively, Black adopts the Scheveningen-style pawn center with e6, chosen in 28.6% of games (1.21M recorded) and evaluated at +0.46. Following e6 Qd2 b5 f3 Nbd7 g4, White scores 50.1% while preparing opposite-side castling.

Minor Alternatives

Other setups remain relatively rare. Black tests Nc6 in 4.7% of games (199K recorded, eval +0.48), where White scores 54.8% along Nc6 h3 e5 Nb3 Be6 Qf3. The queen sortie Qc7 accounts for 1.6% of games (67K recorded, eval +0.46), leading into Qc7 f3 h5 Nd5 Nxd5 exd5 where White scores 51.2%.
