Overview

Sicilian Defense: Smith-Morra Gambit is a gambit, classified under ECO code B21 within the Semi-Open Games family. As with all gambits, one side sacrifices material early — usually a pawn — in exchange for development, open lines, or initiative.

The Semi-Open Games group covers semi-open games — replies to 1.e4 where Black declines the symmetrical 1…e5 in favour of an asymmetric pawn structure.

The line arises from 5 plies — specifically the moves 1. e4 c5 2. d4 cxd4 3. c3.
