The Reversed Sicilian: 1.c4 e5 2.Nc3... Nc6 arises after 1.c4 e5 2.Nc3 Nc6 and falls under ECO code A25. The knight development to c6 is a strong, flexible choice that keeps the door open for a transposition into the English Four Knights after 3.Nf3. White frequently fianchettoes the light-squared bishop and pursues a queenside offensive, in which case Black may find it effective to push ...f5, creating a pawn duo on f5 and e5 that, supported by a knight on f6, forms an imposing front with real counterattacking potential against White's queenside ambitions. Black must be careful, though, not to overextend these kingside pawns, as White can restrain and dismantle them, seizing the initiative. Beyond the Four Knights, White's primary plan involves placing the bishop on g2, the king's knight on e2, and the rook on b1, with the strategic goal of achieving a favorable d4 break (ideally exchanging Black's e-pawn to consolidate center and queenside control) or supporting a b4 pawn advance, prepared by a3 and Rb1. Exploiting the resulting queenside space advantage while containing Black's kingside counterplay requires care — White should not neglect the kingside entirely. A typical sequence illustrating White's edge runs 3.g3 f5 4.e3 Nf6 5.Nge2 Bb4 6.Bg2 O-O 7.O-O d6 8.d4 with a slight advantage, and if Black pushes ...e4, White can undermine it with f3, opening the f-file for the rook in the process. With 5.6 million Lichess games across all rating levels, it is a well-established opening choice.
