Summary
The Sicilian Defense: Rossolimo Variation arises after 1.e4 c5 2.Nf3 Nc6 3.Bb5 and falls under ECO code B30. 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.
- White is often happy to trade the b5-bishop for the c6-knight whenever that leaves Black with doubled pawns, either at once or after being provoked.
- White castles quickly and stays flexible in the centre, choosing between d3 or preparing d4 with Re1 and c3.
- It is a practical way to dodge the sharp, heavily analysed open Sicilians.

Rossolimo first played 3.Bb5 against the 2...Nc6 Sicilian in 1948, and Rashid Nezhmetdinov took it up in 1956. It later became a respected top-level weapon because it offers White chances of an opening advantage without entering the wild complications of the open Sicilians, notably the sharp Sveshnikov.
Named after: Named for Nicolas Rossolimo (1910-1975), a Kyiv-born grandmaster who won the French Championship and the U.S. Open and championed 3.Bb5.
