Sicilian Rossolimo Attack

Start by controlling the center with your king pawn.

e4 — The King's Pawn opening — White claims the center and opens diagonals for the queen and kingside bishop. The most popular first move in chess. Black's main responses: - 1. ..e5 — Open Game, matching White's center - 1. ..c5 — Sicilian Defense, fighting for d4 asymmetrically - 1. ..e6 — French Defense, preparing ..d5 - 1. ..c6 — Caro-Kann, also preparing ..d5

Develop the knight and prepare to open the center with d4.

♘︎f3 — The Open Sicilian begins. White develops naturally and prepares d4, which will open the position. This is the most principled approach against the Sicilian. Black's main responses determine the specific variation: - 2. ..d6 — Najdorf, Dragon, Classical - 2. ..♘︎c6 — Sveshnikov, Kalashnikov, Rossolimo - 2. ..e6 — Kan, Taimanov, Scheveningen

Target the knight on c6 with your bishop.

♗︎b5 — The Rossolimo Attack! Instead of entering the heavily theoretical Open Sicilian with 3. d4, White targets the knight and prepares to trade it. The idea is to damage Black's pawn structure — after ♗︎xc6, Black gets doubled c-pawns. This system has been a favorite of top players like Magnus Carlsen and Fabiano Caruana, who prefer the strategic clarity it offers over the tactical jungle of the Open Sicilian.

Execute the key trade to damage Black's pawn structure.

♗︎xc6 — White executes the Rossolimo trade! By capturing the knight, White damages Black's pawn structure — after ..dxc6, Black has doubled c-pawns and a semi-open d-file. White gives up the bishop pair but gains a lasting structural advantage. The timing is important — White trades before Black can play ..a6 to challenge the bishop, or before the bishop gets chased away for nothing.

Support your center pawn with a solid structure.

White establishes a solid pawn structure with d3, supporting the e4 pawn and preparing piece development. This modest move reflects the Rossolimo's positional character — White is in no rush to push d4. The d3/e4 setup gives White a stable center while keeping the position closed enough that Black's bishop pair has less scope.

Prevent the bishop pin on g4 before developing further.

h3 — A useful prophylactic move — White prevents ..♗︎g4 pinning the ♘︎f3, and creates a safe retreat square on h2 for the king if needed. This also prepares a potential g4 pawn advance for a kingside attack later. Prophylaxis is a key concept in the Rossolimo — White plays useful waiting moves while Black struggles to find an active plan.

Develop your knight to support e4 and control d5.

♘︎c3 — White develops the knight to c3, reinforcing the e4 pawn and controlling d5. The knight on c3 also supports a future ♘︎d5 outpost — one of White's key strategic ideas in the Rossolimo. With both knights developed and h3 played, White is ready to decide on a plan: ♗︎e3 + ♕︎d2 prepares queenside castling and a kingside pawn storm.

Develop the bishop to prepare queenside castling.

White develops the bishop to e3, aiming at the c5 pawn and preparing ♕︎d2 with queenside castling. The bishop on e3 is well-placed — it supports d4 if needed and eyes the weakened queenside pawns. The ♗︎e3 + ♕︎d2 + O-O-O setup is White's most aggressive plan, preparing a kingside attack with g4-g5 while the king sits safely on the queenside.

Prepare queenside castling.

♕︎d2 — White prepares to castle queenside. The queen on d2 supports the ♗︎e3 and enables the thematic ♗︎h6 trade. With O-O-O, White will launch a kingside pawn storm. This is the heart of White's strategy in the Rossolimo: opposite-side castling creates mutual attacks, but White's superior structure gives the initiative.

Target the fianchettoed bishop to weaken Black's dark squares.

♗︎h6 — The thematic exchange! White targets Black's fianchettoed bishop — the most important defender of the dark squares around Black's king. Trading it off will leave Black with weakened dark squares on the kingside. This is a signature Rossolimo idea: White already traded the light-squared bishop for a knight, and now trades the dark-squared bishop for Black's strongest piece.

Complete the trade to weaken Black's dark squares permanently.

♗︎xg7 — White completes the strategic exchange, eliminating Black's powerful fianchettoed bishop. The dark squares around Black's king (f6, g7, h6) are now permanently weakened. White will target these squares in the middlegame. This trade is the culmination of the Rossolimo strategy: first trade ♗︎b5 for the knight (structural advantage), then ♗︎h6 for the bishop (dark-square control).
