In the Smith Morra Gambit, White’s aim is to complete his development as quickly as possible and to exert pressure on black’s position via the open lines.
I think the understanding of this gambit is best conveyed by this quote from Marc Esserman in his great book:
As I’d do with any serious opening, I will not stop the analysis in each critical variation until I have demonstrated that White is fighting for the advantage. Yes, that is not a misprint - that White is fighting for an advantage in the Morra Gambit.
-Marc Esserman in his book Mayhem in the Morra!
There is some great video content about the Smith Morra Gambit available on YouTube.
Hanging Pawns has an excellent video in his series on the Sicilian Defense in which he talks about the Smith Morra theory. Even more analysis is done by ChessNetwork in this.
The Saint Louis Chess Club channel has a video in which the legend Yasser Seirawan analyses a game played by a participant in the gambit.
If you want to see live games in the Morra, Eric Rosen has the right ones for you. He has a video in which he plays against the opening and one in which he plays the opening himself.
