Sicilian Defense: Alapin Variation

Alapin Variation
1.2.
What Is The Alapin Variation?
2.c3 refuses the Open Sicilian. Instead of trading the d-pawn for Black's c-pawn, White prepares d4 and builds a broad centre on d4 and e4 that pushes Black's pieces back. The cost is that c3 robs the b1 knight of its natural square, so White's queenside lags and Black gets time to strike at the centre at once.
That explains 2...d5 3.exd5 Qxd5: the queen sits safely because Nc3 is unavailable, unlike the Scandinavian. The other main try, 2...Nf6 3.e5 Nd5, concedes space for a secure knight. Games are decided by the pawn structure that follows: after ...cxd4 cxd4 White owns an isolated d-pawn with active pieces, and Black blockades d5 and heads for the endgame.
