Blacks accepts the gambit and takes the knight, thinking they're good. Previous move may seem like a blunder, but this position gives you 53% on win. On the meanwhile White can launch a good attack by playing d4 and pressuring the center. This move can lead to many variations.

For Black to succeed the most, they have to play in a way that undevelops their pieces at first, which seems very strange, but then as White develops their queen, making sure not to lose defense of the b7 pawn by moving their bishop, and pushing back White's threats possibly a turn in advance. Eventually, Black will gain back space and will be able to develop their pieces again.
