Sicilian, Rossolimo Variation
The anti-Sicilian of champions: 3.Bb5 pressures c6 and steers towards doubled-pawn squeezes instead of theory wars.
Sicilian, Rossolimo Variation is one of the most compelling entries in the Encyclopaedia of Chess Openings — and a line that repays every hour you sink into it.
After 5.Re1 the position resolves into a fluid centre — one side has staked a central pawn the other must decide how to challenge, so the structure is still being negotiated.

Plans & pawn structures
- 1The centre is still fluid: decide early whether to lock it with a pawn advance or dissolve it with an exchange, because that choice picks the whole middlegame plan for you.
- 2Watch the pawn breaks — both yours and your opponent's. In these structures the player who times the central break better usually wins the game.
- 3Trade correctly: before every exchange ask which piece benefits from the resulting square colours and pawn structure.
Typical middlegame structures
The main line leads to a fluid centre — one side has staked a central pawn the other must decide how to challenge, so the structure is still being negotiated. No files have opened yet, so this is a manoeuvring struggle: improve your pieces and prepare the pawn break that will open the position on your terms.
Traps & tactical motifs
Every sharp opening has its traps — study the forcing lines around the centre and the f7/f2 squares before playing this in rated games.
Watch the typical motifs: pins against the pinned piece, knight forks after the natural captures, and queen sorties to a2/g2-style squares.
