I'm kinda new to chess and I'm trying to learn new openings that are aggressive.
I've used the Fried Liver attack many times. Are there any other opening(s) which are close to the Fried Liver attack that I could use?
The Danish Gambit.
A variation of the four knights with 4. Bc4 will lead to an opening of the game for black by the means of 4...Nxe4 5. Nxe4 d5.
Alternatively, 5. Bxf7+ Kxf7 6. Nxe4 may also occur with sharp play (although you do give up the bishop pair, Black also gave up his right to castle).

If you are familiar with the Fried Liver attack, I recommend you the Evans Gambit.
1.e4 e5 2.Nf3 Nc6 3.Bc4 3...... Nf6 is fried liver attack. 3....... Bc5 4 b4 leads to Evans.
If you are afraid of losing two pawns in the opening, try the Italian game which is similar to Evans.
Try green game, night at the opera etc.
