The Smith Morra Gambit
White sacrifices a pawn to develop quickly and create attacking chances. In exchange for the gambit pawn, White has a piece developed after 4.Nxc3 and a pawn in the center, while Black has an extra pawn and a central pawn majority. The plan for White is straightforward and consists of placing the bishop on c4 to attack the f7-square and controlling both the c- and d-files with rooks, taking advantage of the fact that Black can hardly find a suitable place to post their queen.
The Smith–Morra is uncommon in grandmaster games but is popular at club level.
