The Sicilian Defense: Smith-Morra Gambit arises after 1.e4 c5 2.d4 cxd4 3.c3 and falls under ECO code B21. White sacrifices a pawn in exchange for accelerated development and open lines on the c- and d-files. Black faces a choice between accepting with 3...dxc3 or declining, most commonly via 3...d3. Since the c3 pawn still occupies the knight's natural developing square, White will spend a tempo on recapturing before the knight can reach c3. With 16.5 million Lichess games across all rating levels, it is a specialized opening choice.
