Strategic Ideas
- Flexibility first: Black delays piece commitments to react to White.
- Queenside space: ...b5 expansion is a common long-term plan.
- Central contest: White seeks space with Bd3, c4, or f4 setups.
- Transpositional value: Kan can transpose into Paulsen structures.
- Practical reliability: The line avoids some heaviest Najdorf theory.

Typical Plans
For White

For Black
- Flexible setup: ...Qc7, ...Nf6, and ...b5 depending on White's approach.
- Break at right moment: ...d5 can equalize quickly if prepared.
- Counterplay mindset: Avoid passive defense in open Sicilian structures.
Common Mistakes
