Sicilian Defense: Nyezhmetdinov-Rossolimo Attack with 3...g6

By castling on move four, you're telling Black that you're ready for action while their king is still in the centre. The g6 move weakens Black's kingside dark squares — especially f6 and h6 — and delays their development. Your main plan is straightforward: get your rook to e1, develop your knight to c3 (or sometimes d5 via c3 if the chance arises), and keep the bishop on b5 to pressure the knight on c6. If Black ever moves that knight, your bishop can capture on c6 and double their b-pawns, which often gives you a long-term structural edge. The statistics back up this approach: across all games from this position, you win 49.6% of the time versus Black's 46.6%, with draws making up the rest. That's a healthy plus for a Sicilian line.

Black's most popular move by far is Bg7 (262,024 games), fianchettoing their bishop to complete the kingside setup. This is also what Stockfish recommends as the engine's best move, continuing with Bg7 Re1 Nf6 Bxc6. Your task is simple: play 5.Re1, getting the rook off the a1-h8 diagonal and onto the open file. After 5...Nf6, you trade on c6 with 6.Bxc6, removing Black's best-developed piece and giving them a doubled b-pawn. This pawn structure is a dream for you — Black's queenside becomes rigid, your light-squared bishop's absence is barely felt, and your central pawns (e4 and d4 after the natural break) can roll forward. In this line you score roughly 49.4% — solid, and it's the battleground the engine wants you to fight on.

Your opponents will often play something other than Bg7, and that's where you can pounce. The data shows two clear inaccuracies to watch for: 4...d6 and 4...e6. Both lose roughly half a pawn compared to the best move. Let's look at each: 4...d6 (2,269 games, you score 50.9%) blocks Black's dark-squared bishop and creates a small backward-square problem on d6. You can reply with d4, opening the centre while Black's pieces are still tangled. 4...e6 (1,901 games, you score 52.5%) weakens the d6-square and shuts in Black's light-squared bishop. Here a quick d4 push followed by c4 or even Nc3 can give you a commanding centre. Both mistakes share a theme: Black tries to play a normal closed Sicilian but forgets that your bishop on b5 already applies pressure. The best reply to 4...e6 is the immediate d4 break. The numbers don't lie — when Black deviates, your winning chances go up.

Two other replies deserve your attention: 4...a6 (6,032 games, you score 51.8%) and 4...Nf6 (2,966 games, you score 54.4%). Against 4...a6, Black immediately asks what your bishop intends. The best answer is to retreat to a4, keeping the pressure on c6. If Black ever plays b5 later, your bishop goes to b3 and can target the f7-square later on. Against 4...Nf6, Black challenges your e4 pawn directly. Here you can support with d3 or simply play Re1 and then d4. Your score rockets to 54.4% — the highest among all Black replies — which suggests that club players often overextend or misplace their knight in this line. A natural plan is 5.Re1, then meet 5...d6 or 5...Bg7 with d4, opening lines while Black's knight on f6 lacks a target.

To make things concrete, here is the exact sequence Stockfish recommends when Black plays the best response: 5.Re1 Nf6 6.Bxc6 dxc6 (or bxc6) 7.d4 Bg7. After 7.d4, you open the centre while Black's kingside knights and bishops are still coordinating. The engine evaluates this as a small but stable plus for you. Even if Black recaptures with the d-pawn (6...dxc6) — which is more common — your central presence with e4 and d4 is imposing. The rook on e1 helps you meet any future ...Bg4 pin with h3, and your c2-c3 break (to support d4-d5) is always available. This is the kind of position where you have all the play and Black is left reacting to your threats.
