Sicilian Defense: Nyezhmetdinov-Rossolimo Attack with a6 — A Clear Advantage for White
After 1.e4 c5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6, you've reached one of the most strategically pleasant positions in the Sicilian. By taking on c6, you've surrendered your light-squared bishop — but in exchange, you've damaged Black's pawn structure and seized the initiative. Stockfish rates this +0.72, a clear edge for White. That means you are clearly better here. Over 1.4 million games in the Lichess database confirm you're on the right track: White scores a healthy 51.7% win rate. The real question is how Black recaptures — and whether they know what they're doing. Play through the drill below to learn your best responses and the mistakes to punish.

By playing 4.Bxc6, you're trading a bishop for a knight, but the real prize is Black's pawn structure. No matter how Black recaptures, their queenside pawns become doubled, isolated, or both. That long-term weakness is your anchor for the whole middlegame. You follow up by castling quickly and placing your pawn on d3, keeping the centre flexible while you develop your other pieces. Black will try to use their bishop pair and active play to compensate — but you have the healthier pawns and a clear plan: pressure the c5 pawn, open the centre when it suits you, and make Black's doubled pawns a permanent target.
The Best Move: bxc6 and Your Plan
In over 1.1 million games, Black's most popular reply has been bxc6 (75% of the time), and it's also the engine's recommended continuation. After bxc6, you castle: O-O. Black typically plays d6, and you respond with h3. That little pawn move on the edge is important — it prevents Black's light-squared bishop from pinning your knight to the queen on g4 or from settling on g4 in general. From here, your plan is straightforward: develop naturally, then decide whether to push e4-e5 or play in the centre with d3-d4. The engine prefers this continuation for a reason — it gives you a solid, lasting edge without unnecessary risk.
What If Black Captures with the Queen?
A significant portion of games see dxc6 instead of bxc6. This recapture keeps Black's pawn structure cleaner, but it costs them time — the queen comes out early and can become a target. Your plan stays similar: develop naturally, castle, and look to chase Black's queen around with tempo-gaining moves like d3 and eventually e5 when the time is right. White still scores well here (51.0%), and the engine much prefers the bxc6 line. Don't panic if you see dxc6 — you're still better, and the queen on d8 often ends up awkwardly in the way of Black's own development.
Punishing Black's Biggest Blunders
Some opponents will try to avoid doubled pawns altogether — and they pay a heavy price. If Black plays b6, it's a blunder costing roughly 6.6 pawns. White scores a crushing 81.7% in those games. The move b5 is similarly disastrous (81.1% White wins, loses about 6.4 pawns). Both attempts fail because they leave the c5 pawn weak, fail to develop, and ignore the centre. If your opponent plays e6, it's only a minor inaccuracy (losing about 0.6 pawns), but White still wins 64.5% of the time. The lesson: stay alert after 4.Bxc6. If Black doesn't recapture on c6, there's almost certainly a punishment waiting.

Frequently asked questions
Is the Nyezhmetdinov-Rossolimo Attack a good opening for beginners?
Yes. The Rossolimo (3.Bb5 against the Sicilian) avoids long, sharp theory while giving you a clear strategic advantage. After 4.Bxc6, you damage Black's pawns immediately and have a simple plan: castle, play d3, and pressure the queenside. It's ideal for club players who want to play the Sicilian without memorising endless Najdorf or Dragon lines.
Should I always play 4.Bxc6 in this position?
Statistically and engine-wise, yes. After 3.Bb5 a6, taking on c6 is the best move. The alternative — retreating your bishop — gives Black's a6 pawn a useful tempo and allows them to complete development more easily. Taking on c6 is the principled way to convert your opening advantage into a lasting structural edge.
What if Black recaptures with the queen (dxc6) instead of the pawn?
That's the second most common response, and it's perfectly playable for Black — but you're still better. White wins 51.0% of those games. Develop naturally, castle, and aim to gain time chasing Black's queen. The doubled pawns on c6 and c5 are still a long-term asset for you, even if they're not as damaging as in the bxc6 line.
How do I punish Black if they play b6 or b5?
Both are serious blunders that lose roughly 6.5 pawns. After b6, you can simply take on c5 and Black's position collapses — the a8 rook hangs, and the queen is lost. After b5, similar tactics apply. Keep an eye out: some opponents panic when they see a bishop on b5 and try to 'save' their pawn structure, handing you an instant win.
