1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 (the common Open Sicilian), branching from here into the Najdorf (5...a6), Dragon (5...g6), Scheveningen (5...e6), or Classical (5...Nc6)
Core Ideas
Sicilian is Black's most ambitious defense against 1.e4. Trades c-pawn for White's central d-pawn, giving Black an open c-file and queenside pawn majority. Sicilian is the most-played opening at modern top level, used by Fischer, Kasparov, Carlsen consistently. Very deep theory per variation.
Plan for White
Kingside attack with f4-f5-f6 push (English Attack). Alternative: positional plan with Be2 + Bg5 and long-term center pressure. Must prepare deeply because Sicilian has many variations.
Plan for Black
Queenside counter-attack. Depending on variation: Najdorf ambitious with e5 push, Dragon with g6 bishop fianchetto, Scheveningen with e6 solid, Sveshnikov with immediate e5. All share theme: dictate tempo with queenside initiative.
Grandmaster Tier Context
T3 Competitive Local through T5 Master. Sicilian requires committing to one variation (Najdorf, Dragon, or Sveshnikov) requiring 20-40 hours of study. Grandmaster coaches do not recommend Sicilian for T2 because defensive resources are complex.
