Another use of black’s knight is to control the d4 square indirectly.

Black replies 4.d6 in smith morra gambit accepted

The idea behind black’s 4.d6 move is, to prevent e5 move and in the meantime it opens diagonal for black’s dark square bishop, which is often difficult to develop.
Let’s see how white handles this idea and gets advantage.

In above game, although black made a blunder by taking white’s knight on f3 and because black exchanged his only developed piece, that’s why black went into trouble and lost the game.
Game 2 in d6 variation
Black replies with 4.a6

The idea behind a6 in smith morra gambit accepted is to prevent Nb5 and playing b5 in future for gaining space on queenside and may develop his light square bishop.
Let’s watch one game and see how white gets advantage against a6 move.
Game 1 in a6 variation
Black replies with 4.g6

The idea behind g6 move is very clear, black just wants to avoid central fight for the time being and focus solely on development and safety of his king, by getting castling as soon as possible, and to avoid any tactical shots from white.
Game 1 in g6 variation

This is so far most natural move, challenging white’s knight and controlling d4 square.
This move also open diagonal for kings bishop to develop, but it also has drawback which is weakness of d4 pawn.
