The Sicilian Defense: Rossolimo Variation arises after 1.e4 c5 2.Nf3 Nc6 3.Bb5 and falls under ECO code B31. By placing the bishop on b5, White targets the c6 knight in a manner reminiscent of the Ruy Lopez. The crucial distinction, however, is that in the Rossolimo, White frequently intends to capture the knight and inflict structural damage on Black's queenside, aiming for a long-term positional edge that often proves especially valuable in endgames. Black has several ways to respond to 3.Bb5. The most popular is 3...g6, preparing a Dragon-style fianchetto of the king's bishop. White then has a choice: 4. Bxc6 to immediately compromise Black's pawn structure, 4. O-O Bg7 5. c3 with plans to expand in the center via d4, or 4. c3 right away to prepare the same d4 advance. With 16.1 million Lichess games across all rating levels, it is a well-established opening choice.
