user109: It seems like the Fried Liver Attack is too much for black to handle, so it seems it is best to avoid the Two Knights Defense as Black.  An example of the Fried Liver Attack is below and Black just seems lost.  Is there something Black can do?

user118: There is a very interesting counter to the fried liver attack that i came across.

There are lots of variations covered by matoJelic, please have a look.

user2001: I recently showed an interesting variation for black to a few friends at a tournament. There were the good old times when me and my chess club buddies spent hours on end analyzing these sorts of positions. Well, it goes like this:
[FEN ""]
1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 Nd4 6.c3 b5

Yes, it looks totally crazy! And it is, too! As far as I remember, the evaluation is that black is equal or slightly better. The variations are ultra sharp. In several paths, the white (!) king will be in trouble! That is opposed to the accepted variation (Nxd5) where the black king has to take a walk. The variation above can continue like this:
[FEN ""]
1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 Nd4 6.c3 b5 7.Bf1 Nxd5 8.cxd4 Qxg5 9.Bxb5+ Kd8

You should definitely check this out with the latest games and with an engine! It should be equal or unclear! An unprepared white player will quickly collapse at your feet! Happy hunting!

user307: In Two Knights defense black doesn't have to play 5...Nxd5?! The main line is 5...Na5, where black sacrifices a pawn, but gets active play for compensation. The game could continue like this:
[FEN ""]
1. e4 e5
2. Nf3 Nc6
3. Bc4 Nf6
4. Ng5 d5
5. exd5 Na5
6. Bb5+ c6
7. dxc6 bxc6
8. Be2 h6
9. Nf3 e4
10. Ne5 Bd6
11. d4 exd3
12. Nxd3

Besides 5...Na5, Black also has 5...Nd4 and 5...b5.
A very interesting continuation is the Traxler attack (4...Bc5!?):
[FEN "r1bqk2r/pppp1ppp/2n2n2/2b1p1N1/2B1P3/8/PPPP1PPP/RNBQK2R w KQkq - 6 5"]

Black does not defend the f7-square, and it first might look like a blunder, since 5.Nxf7 leads to a fork. However black has plenty of attacking resources after 5...Bxf2. Therefore, white usually plays 5.Bxf7, black is down a pawn, and loses castling ability, but has some compensation due to semi-opened file and piece activity.
