Not sure what you're looking for?
clue: name of the openimg?
Two Knights Defense - Main Line (the first diagram you posted...)
It can be, but I wanted to make an Italian.
Who's move is it?
Your main line was 5. ... Na5, variation was 5. ... Nxd5 6. d4? 6. Nxf7!! With the fried liver attack.
You give a suspicious moves 2 exclamation marks, and a good one a question mark.
