Alapin Sicilian
White’s one-move answer to the Sicilian: 2.c3 prepares d4, aims for a full pawn centre and steps around the Open Sicilian theory.
The Alapin Sicilian is White’s reply 2.c3 to 1…c5. The idea is simple. The c-pawn supports the d4 advance, so if Black exchanges on d4 before playing …d5, White takes back with the pawn and has two pawns in the centre, at least until Black hits them with …d5. It is named after the Russian master Semyon Alapin, one of its first advocates, and Evgeny Sveshnikov, better known for the Sicilian line that carries his name, played it with White for decades.
Its practical appeal is that one move answers the whole defence. You do not have to learn the Najdorf, the Dragon and the Sveshnikov from White’s side. The fight is about the centre and the structures that come out of it: an isolated d-pawn, a pawn on e5, or a French-type chain. And it holds up in practice. In rated Lichess games White takes 52 to 53% of the points after 2.c3 (a win counts as one, a draw as half) at every rating band from 1400 to 2200, one to two percentage points more than after 2.Nf3, the most popular move.
Main lines
- 1.e4 c5 2.c3 d5 3.exd5 Qxd5 4.d4The Barmen Defense, the main line. Black’s queen comes out early; White develops around it with Nf3 and Be2, and after an exchange on d4 brings the knight to c3 and plays with an isolated d-pawn.
- 1.e4 c5 2.c3 d5 3.exd5 Nf6The Anti-Alapin Gambit. Black leaves the pawn on d5 for quick development; White holds on to it with 4.d4 cxd4 5.Bb5+ Bd7 6.Bc4.
- 1.e4 c5 2.c3 Nf6 3.e5 Nd5 4.d4 cxd4 5.Nf3The other main line. The e5 pawn gains space, the knight on d5 has few good squares, and Black hits back at the centre with …d6 or …e6.
- 1.e4 c5 2.c3 Nc6 3.d4The most common reply from 1400 to 1800. After 3…cxd4 4.cxd4 White has the full centre; after 3…d5 4.exd5 Qxd5 the play resembles the Barmen Defense.
- 1.e4 c5 2.c3 e6 3.d4 d5French-style play. 4.e5 leads to an Advance French; 4.exd5 exd5 opens the game, and Black’s d5 pawn can end up isolated.
- 1.e4 c5 2.c3 d6 3.d4Black allows the ideal centre. After 3…cxd4 4.cxd4 White develops with Nc3 and Nf3; against 3…Nf6, 4.Bd3 protects e4.
- 1.e4 c5 2.c3 e5 3.Nf3 d6 4.Bc4Black stops d4 for a moment. White develops quickly and plays d4 anyway, opening the centre while ahead in development.
- 1.e4 c5 2.c3 g6 3.d4 cxd4 4.cxd4 d5A fianchetto with a central strike. After 5.exd5 Nf6 6.Nc3 Nxd5 7.Qb3 White puts pressure on d5 and f7.
Key plans & ideas
- Build the centre: 2.c3 is there to play d4 and to meet …cxd4 with cxd4. Unless Black has already hit e4 with …d5, that leaves pawns on d4 and e4, or on d4 and e5 after 2…Nf6 3.e5.
- Play with the isolated pawn: after 2…d5 3.exd5 Qxd5 4.d4 and an exchange on d4, White often has a lone d-pawn. Put the pieces on active squares (Nf3, Nc3, Bd3 or Be2) and look for the d4-d5 break or a kingside attack instead of trading pieces.
- Gain time on the queen: once the c-pawn has taken back on d4, the c3 square is free and Nc3 comes with tempo against a queen on d5. Against …Bg4, h3 asks the bishop to make up its mind.
- Use the e5 pawn against 2…Nf6: after 3.e5 Nd5 the pawn takes f6 and d6 away from Black, and the knight in the centre is a target for Bc4. If Black castles early while your bishop stands on d3, look for Bxh7+.
- Pick your French structure against 2…e6: 3.d4 d5 4.e5 gives an Advance French, while 4.exd5 exd5 opens the game and aims at the d5 pawn, which is often left isolated after dxc5.

Frequently asked questions
Is the Alapin Sicilian good for club players?
Yes. It answers the whole Sicilian with one move and leads to positions you can understand: a pawn centre, an isolated d-pawn or a French-type structure. Knowing the plans matters more than long forcing lines, which suits players who would rather not learn the Open Sicilian from White’s side.
What is the best reply to 2.c3 for Black?
The two main lines are 2…d5 and 2…Nf6, and both give Black a sound game. They are also what strong players choose: in rated Lichess games at 2200, 2…d5 and 2…Nf6 make up about six of every ten replies to 2.c3, while at 1400 four players in ten answer 2…Nc6.
What is the difference between the Alapin and the Smith-Morra Gambit?
Both put a pawn on c3, but the Smith-Morra plays 2.d4 first and offers a pawn with 2…cxd4 3.c3. The Alapin plays 2.c3 before d4, so White gives nothing away and Black chooses the structure with the second move.
Do strong players use the Alapin?
Yes, as a sound way around the main Sicilian theory. Sveshnikov played it with White for decades, and in rated Lichess games 2.c3 is played a little more often at 2200 than at 1400.
