Just like the title says, is there a name for the line starting with 4.Ng5 in 1.e4 e5 2.Nf3 Nc6 3. Bc4 Nf6 4. Ng5 called?
Wikipedia article https://en.wikipedia.org/wiki/Two_Knights_Defense, does not give a name.
This Youtube video https://www.youtube.com/watch?v=rKoZkrBWDbU refers to 4.Ng5 as The Knight Attack, but I searched for it and I don't see other references to The Knight Attack.
Also, often people refer to 4.Ng5 as Fried Liver attack, which I believe is incorrect, since Fried Liver attack arises later in the game, after 1.e4 e5 2.Nf3 Nc6 3. Bc4 Nf6 4. Ng5 d5 5. exd5 Nxd5 6. Nxf7.
