The Sicilian Defense: Alapin Variation arises after 1.e4 c5 2.c3 and falls under ECO code B22. White prepares to push d4, using c3 as support. This is one of the main "anti-Sicilian" systems, chosen by White to bypass the heavily theoretical main lines of the Open Sicilian. If Black responds with the common amateur move 2...Nc6!?, play continues 3. d4 cxd4 4. cxd4, and White achieves a two-pawn centre. Black's original idea of trading a less-important flank pawn for White's central d-pawn is neutralized because White recaptured with the c-pawn. The line typically continues 4...d5 5. exd5 (since 5. e5?! lets Black set up an improved French structure with ...Bf5 and ...e6) Qxd5 6. Nf3 e5 7. Nc3 Bb4 8. Bd2 Bxc3 9. Bxc3 e4 10. Ne5 Nxe5 11. dxe5 Ne7 with a slight White edge. The former standard reply, 2...d5, threatens 3...dxe4 and after 3. exd5 Qxd5 (the Barmen Defense) White can still play 4. d4 but no longer gets two centre pawns and Black enjoys a lead in development. Because the c3 square is occupied, White cannot develop Nc3 with tempo against the queen, and Black tries to delay ...cxd4 until White has placed the knight elsewhere to prevent c3 from becoming available again. With 27.6 million Lichess games across all rating levels, it is a well-established opening choice.
- White prepares d4 with c3 support, aiming to build a strong pawn centre
- Black strikes back at the centre right away, most often with 2...d5 or 2...Nf6
- A solid Anti-Sicilian choice championed by several grandmasters
History and Notable Players
It arises from the Sicilian Defense. Among the most prolific practitioners on the White side are Evgeny Sveshnikov (342 games), Drazen Sermek (250 games), Dusko Pavasovic (243 games). On the Black side, notable exponents include Zdenko Kozul (68 games), Miso Cebalo (68 games), Ognjen Cvitan (51 games).
Early theorists were dismissive: Tarrasch thought 2...d5 gave Black a good game, and Modern Chess Openings still rated it poorly in 1972. Opinion later turned around completely, and today it is regarded as one of White's soundest and most reputable Anti-Sicilian systems.
Named after: Semyon Alapin (1856-1923), a Russian master.
Notable players: Evgeny Sveshnikov, Sergei Tiviakov, Eduardas Rozentalis, Magnus Carlsen
