Sicilian Defense: Dragon Variation, Classical Variation, Stockholm Attack is a chess opening that arises after 1.e4 c5 2.Nc3 d6 3.f4 Nc6 4.Nf3 g6 5.d4 cxd4 6.Nxd4 Bg7 7.Be3 Nf6 8.Be2 O-O 9.Nb3 Be6 10.O-O Na5 11.f5 Bc4 12.Nxa5 Bxe2 13.Qxe2 Qxa5 14.g4. It is classified B74 in the ECO system, and the position after these moves has black to move. The Sicilian Defense is Black's most popular answer to 1.e4, meeting it with 1...c5 to fight for the centre asymmetrically rather than mirroring White's pawn. Because the pawn structures that result are unbalanced from move one, the Sicilian produces sharper and more double-edged positions than any other reply to the king's pawn, and it has the best practical scoring record for Black at master level.
Black accepts a slight lag in development in exchange for a queenside pawn majority and the half-open c-file, which becomes the main artery for counterplay. White typically attacks on the kingside while Black attacks on the queenside, so games often become a race in which tempo matters more than material.
Players who want winning chances with Black and are willing to learn theory. The main lines are heavily analysed, and being caught unprepared in the Najdorf or Dragon can lose quickly.
