What's the Italian Anti Fried Liver?
First, you take an Italian: 1. e4 e5 2. Nf3 Nc6 3. Bc4
The Fried Liver Attack is when White plays Ng5 hoping for a fork on f7. The Anti-Fried Liver means Black plays 3. ...h6 to prevent that.
The actual "fried liver" starts only after 3. ... Nf6 4. Ng5 d5 5. exd5 Nxd5?? Then White has the options of Nxf7 right away or d4 and sac next move (the Lolli Attack).

OMG, that 3...h6 stuff doesn't deserve a name, other than perhaps, the blunderful variation. It's known to be terrible and I even gave a lecture on it at my chess club some years ago, because so many people played it and got what they had coming. (4. d4 is best, and the advantage in development and space is better than being up a pawn.
Instead of this garbage, people should learn the main lines of the Two Knights: 3....Nf6 4. Ng5 d5 5. exd5 Na5 and so on.
