Sicilian Defence: Rossolimo Variation
Also known as Rossolimo
1.e4 c5 2.Nf3 Nc6 3.Bb5
The Rossolimo is White's quiet anti-Sicilian: 3.Bb5 trades the light-squared bishop for Black's knight, dodging heavy mainline theory and steering the game toward calm, manoeuvring positions where understanding beats memorisation.

What it does
After 1.e4 c5 2.Nf3 Nc6, White plays 3.Bb5, attacking the c6-knight. Often White captures it, giving Black the bishop pair but saddling them with doubled c-pawns. White then builds a modest, flexible setup with d3, O-O and Re1, aiming to play on the slightly damaged black structure rather than launch a sharp attack. The result is a strategic, low-theory battle.
When to use it
Reach for the Rossolimo when you want to sidestep the vast, sharp theory of Open Sicilians (Najdorf, Sveshnikov, Dragon and friends) and play a sound, positional game. It suits players who prefer clear plans and structural understanding over memorising long forcing lines, and it stays fully respectable at every level.
Why it works
By swapping on c6, White trades the often-passive light-squared bishop for an active black knight and inflicts doubled pawns. Black gains the bishop pair, but those pawns can become long-term targets, and Black sometimes struggles to make the bishops count in closed structures. White's simple, harmonious development is easy to handle and avoids the tactical traps of the Open Sicilian.
Key ideas
- Trade Bxc6 to give Black doubled c-pawns and a structural target
- Set up calmly with d3, O-O and Re1 rather than a sharp attack
- Restrain Black's bishop pair by keeping the position semi-closed
- Aim for the e4-e5 or d3-d4 break at the right moment
- Play on structure and manoeuvring, not memorised theory
- Knights often find strong outposts on light squares like d5
Watch out
No quick tricks define the Rossolimo - it is a strategic system. Watch out for Black's ...e5 and ...f5 expansion, which can activate the bishop pair and seize space if White is passive. Conversely, if White opens the position too early with Black's bishops well placed, those two bishops can become dangerous in the long run.
