The idea

White offers a pawn on move three to blast open the center and open lines for every piece, banking entirely on quick development and attacking chances against a Black king that hasn’t castled yet. There’s no long-term structural compensation waiting in reserve if the attack fizzles - only tempo, which has to be spent fast.
