Rossolimo Variation: d6 — A Small but Steady Edge for White
After the standard Rossolimo move order — 1.e4 c5 2.Nf3 Nc6 3.Bb5 d6 — you push 4.d4, and Black now has to decide how to handle the centre. Stockfish evaluates this position at +0.36, a small but consistent plus for you. With White winning 50.8% of games (against just 4.2% draws), this variation offers solid winning chances without wild complications. The drill below lets you practise the critical moment: Black has just moved, and you need to know which reply to welcome and which to punish.

This position is about control of the d4-square and the dark squares in the centre. By playing 3.Bb5, you've pinned the knight on c6 against the king, making it harder for Black to challenge your d4 advance. After 4.d4, Black's most principled move is to capture: 4...cxd4. That leads to a clean Open Sicilian where you recapture with the knight (5.Nxd4) and follow up with Bd7 and Nc3, with a sound development advantage. Black's other options are all inaccuracies that leave you with a bigger edge — but only if you know how to exploit them.
The Engine's Best Answer
Stockfish's top recommendation is 4...cxd4, which appears in 253,800 games in the Lichess database (by far the most common reply). The engine's ideal continuation is 5.Nxd4 Bd7 6.Nc3, giving you a comfortable Open Sicilian with the bishop pair and extra space. If Black tries anything else, you gain: Black scores just 47.7% after cxd4 — not terrible — but the real opportunity comes when they deviate into an inaccuracy.
Punish Black's Most Common Mistakes
Several of Black's alternatives look natural but are statistically subpar. Here are the main ones to be ready for: - 4...Bd7 (78,036 games) — an inaccuracy costing ~0.6 pawns. Black blocks the pin, but you can keep developing with 5.dxc5 or continue naturally; you score 54.1% from here. - 4...a6 (59,540 games) — an inaccuracy costing ~0.5 pawns. Black tries to kick the bishop, but 5.Ba4 or 5.Bxc6 leaves you with a strong centre and White scores 53.0%. - 4...Qa5+ (21,258 games) — an inaccuracy costing ~0.6 pawns. This check is easily parried with 5.Bd2 or 5.Nc3, and you score a solid 56.5%. - 4...Bg4 (5,911 games) and 4...Nf6 (4,726 games) are less common but also favourable — you score 58.9% and 60.4% respectively. None of these equal the engine's top choice; your job is to stay calm and outplay them in a slightly superior position.
The Right Mindset for This Variation
The Rossolimo Variation: d6 isn't about crushing your opponent with a prepared trap. It's about reaching a slightly better middlegame where your development and space advantage add up over time. The engine's +0.36 evaluation reflects a real but modest edge — you are better, but not winning by force. Trust your extra tempo, keep your pieces active, and don't force matters. The statistics back this up: your 50.8% win rate means you convert that small edge into a full point more often than Black does, especially if they wander into one of the inaccurate replies listed above.

Frequently asked questions
Is the Rossolimo Variation good for White?
Yes. After 1.e4 c5 2.Nf3 Nc6 3.Bb5 d6 4.d4, Stockfish gives White a +0.36 advantage — a small but genuine edge. White wins 50.8% of games at this position, and when Black plays anything other than 4...cxd4, your winning chances go up even further.
What is Black's best reply to 4.d4 in the Rossolimo?
The engine's top choice is 4...cxd4, which leads to the Open Sicilian with 5.Nxd4 Bd7 6.Nc3. It's also by far the most popular move, appearing in over 253,000 games. Other moves like 4...Bd7, 4...a6, or 4...Qa5+ are all inaccuracies that give you a bigger edge.
How should I respond to 4...a6 or 4...Bd7?
Both are inaccuracies that cost Black roughly half a pawn. Against 4...a6, you can retreat the bishop to a4 or exchange on c6 — either way you keep your centre. Against 4...Bd7, simple development with dxc5 or Nc3 works well. In both cases your winning percentage jumps above 53%.
What does the typical middlegame look like after 4.dxc5?
This position doesn't feature 4.dxc5 — the bishop is on b5, and the typical capture is on d4. After 4...cxd4 5.Nxd4, you'll get an Open Sicilian with a knight on d4, the bishop on b5 pinning the c6-knight, and a solid development lead. Black often plays Bd7 to break the pin, then you develop Nc3 and castle.
