Most up to date Sicilian variations.


not 100% sure about all variations but I would rank them like this...
Tier A: Najdorf / Sveshnikov
Tier B: Taimanov / Kan / Dragon / Classical / Four Knights
Tier B-: Scheveningen / Accelerated Dragon
Tier C: various 2nd moves like a6, b6, Nf6 / Dragondorf / Pin variation / 3... Qb6
Scheveningen and Accelerated Dragon depend on the move order. Scheveningen goes up when the game starts as a Najdorf or Taimanov and transposes then. Accelerated Dragon is mainly played after 2... Nc6 3. Nc3 so White can't play c4 anymore.
