How to Play the Sicilian Najdorf 6.Bg5 as Black

With 835,713 games played from this exact position, we have an enormous sample to learn from. Black wins 51.1% of the time, while White wins 45.2% and only 3.7% end in draws. Those numbers immediately tell you two things. First, this is a fighting opening — almost no early peace treaties. Second, Black actually outscores White at the board, even though the engine thinks the position is essentially equal (+0.20 in White's favour, a tiny edge that means nothing to a human). That gap between engine evaluation and practical results is exactly why the Najdorf Bg5 is such a trusted weapon for Black at the club level: the positions are well understood from Black's side, and there are plenty of ways to punish an imprecise White move.

Stockfish's best suggestion for White is 7.Qd2, planning to follow up with b5, f3, and Bb7. This setup reinforces the centre, prepares to castle long, and keeps the g5 bishop protected. Against this, Black's typical plan is to complete development, challenge the centre with ...d5 or ...b5/...Bb7/...Nbd7, and look for counterplay on the queenside or in the centre once White castles long. While 7.Qd2 scores only 48.2% for White in practice, it's the engine's first choice for a reason — it's solid and keeps the pressure. As Black, you should be ready for a slower, strategic game if White chooses this path, but your equal position means you have nothing to fear.

Nearly every White player below master level reaches for one of four moves. Here is how they perform, from Black's perspective: 7.f4 (195,197 games) is the most common — White gets 49.4%, making it the toughest test but still statistically fine for you. 7.Bd3 (161,618 games) sees White score only 43.2% — that is a fantastic number for Black, meaning you should be especially alert for opportunities if your opponent plays this natural-looking developing move. 7.Bc4 (121,028 games) also gives White just 42.6%, so again Black is doing well. 7.Qf3 (61,460 games, White 46.7%) is less common but still respectable. Notice the pattern: White's most 'theoretical' move (7.f4) gives them the best score, while the natural developing bishop moves (Bd3, Bc4) underperform. That tells you that White needs to know what they are doing to keep the balance.

Black's biggest job in this position is avoiding a passive or cramped setup. Because White's bishop on g5 can exchange itself for your knight on f6, many Black players rush to play ...h6 or ...g6 to 'ask the question' — but those moves can weaken your kingside prematurely. The most frequently punished Black inaccuracy is ...d5 without sufficient preparation, which opens lines for White's pieces before your development is complete. Stick to the classical Najdorf recipe: keep your king safe, complete your queenside development, and wait for the right moment to break in the centre. The engine's plan of ...b5/...Bb7 is a reliable blueprint that has worked for Black for decades.
