How to Play the Sicilian Defense: Closed, Anti-Sveshnikov Variation: Bb5 as Black
After 1.e4 c5 2.Nf3 Nc6 3.Nc3 e5 4.Bb5, you've entered the Anti-Sveshnikov line of the Closed Sicilian — a fighting system where Black immediately challenges White's central control. You've just played 4...d6, protecting the e5-pawn and preparing to kick the bishop. The engine gives this position +0.27, a tiny edge for your opponent, but don't let that scare you: across over 250,000 games from this exact spot, Black actually scores an impressive 52.1%, compared to just 43.2% for White. The statistics suggest that most club players handle White's side inaccurately — and this page will show you how to capitalise. Jump into the interactive drill below to practise the position.

The Closed Sicilian with 4.Bb5 leads to a unique pawn structure compared to Open Sicilian lines. By playing 3...e5, Black seizes a space advantage in the centre and blocks the long diagonal for White's dark-squared bishop. Your move 4...d6 is rock-solid: it defends the e5-pawn and keeps the option of driving the bishop back with ...a6 and ...b5. White's bishop on b5 is awkwardly placed — it pins the knight to the king, but it can also become a target. You're not fighting for equality here; you're fighting for a comfortable middlegame where Black's central pawn duo (...c5 and ...e5) restricts White's pieces. The statistics back this up: Black scores over half the points in practice, even though the engine slightly prefers White.
The Engine's Blueprint: Why d3 Is Critical
Stockfish's top recommendation here is 5.d3, intending to consolidate the centre and follow up with a6, Bc4, and b5 — a flexible setup. If White plays this accurately, Black must be careful: the engine sees a +0.27 edge for White, meaning you are slightly worse. But here's the good news: most White players don't find d3. In over 252,000 games, the most popular move is 5.Bxc6+, played 83,214 times — and that is a mistake. The engine says Bxc6+ loses about 0.8 pawns compared to the best move, and White scores just 42.5% from there. You'll be happy to see your opponent grab the bishop pair too early.
Punishing White's Most Common Inaccuracies
The FACTS list three clear inaccuracies for White in this position, and all of them are common at club level. Here is what to do against each: 5.Bxc6+ — This gives up the bishop pair for no real gain. After 5...bxc6, Black's pawn structure is damaged but you get the two bishops and open lines for your pieces. The engine calls this an inaccuracy (losing ~0.8 pawns). 5.Nd5 — A flashy-looking knight sortie that is actually premature. It loses about 0.5 pawns. Black can reply 5...a6 or 5...Nf6, chasing the knight away and developing with tempo. 5.h3 — A passive waiting move that also loses ~0.5 pawns. Black simply plays 5...a6 or 5...Nf6 and builds a comfortable game. In all three cases, White deviates from the principled 5.d3, and Black's winning chances jump significantly.
What the Stats Say About Your Chances
Let the numbers guide your confidence. From this exact position (after 4...d6), here is how Black fares against each of White's top five choices: Against 5.Bxc6+ (83,214 games), White scores just 42.5% — Black is doing very well. Against 5.d3 (64,774 games), White scores 43.7% — still below average for White, and comfortably playable for you. Against 5.O-O (55,228 games), White scores 43.6% — more of the same. Against 5.Nd5 (25,967 games), White scores only 42.3% — a great sign for Black. Against 5.h3 (8,008 games), White's score rises to 46.9% — still below a draw rate, meaning Black out-scores White here too. Overall, no matter which move White picks, Black wins more than half the games. The engine says you are slightly worse, but the practical results prove otherwise.

Frequently asked questions
Is the Anti-Sveshnikov with 4.Bb5 good for Black?
Yes. While Stockfish gives White a tiny edge (+0.27), Black scores 52.1% across over 250,000 games from this position. The practical results favour Black because many White players mishandle the line by playing premature trades like Bxc6+.
What is White's best move after 4...d6?
Stockfish recommends 5.d3, aiming to solidify the centre and prepare a6, Bc4, and b5. If White plays this, you are slightly worse according to the engine. However, d3 is not the most popular move in practice — many White players choose other options that are less accurate.

Yes, the engine calls 5.Bxc6+ an inaccuracy that loses about 0.8 pawns compared to the best move (5.d3). From 83,214 games, White scores only 42.5% after this exchange. You should welcome it: take back with 5...bxc6 and enjoy the two bishops.

In 252,315 games from this exact position, Black won 52.1% of the time, White won 43.2%, and only 4.7% ended in draws. That means Black scores more than half the points — an excellent practical result for a line where the engine gives White a small theoretical edge.
