Which is the best varaition of the italian game?



The fried liver attack is really fun to play.
Even if they decline it, your a pawn up, but behind in development while their structure is ruined. I'll post an example

Yeah, white will be having fun if Nxd5 so black will usually avoid that. I go with the Na5 line after exd5.

Hmm, Qf3. I might try that, it looks good.
Anyway, yeah. You can always play this line to "decline" the fried liver I guess.

Black has to be pretty sharp or ignorant to willingly play 5....Nxd5. Black should really know what he/she is doing before going into it. Another strong reply (and arguably better (by people who know more about chess than me)) is the Lolli attack which goes (if you don't know)
And clearly black is in for a difficult time, even if not actually worse, being able to come up with moves over the board isn't so simple, and we are not computers. But, yeah, the 'declining' line to the Fried Liver as you put it is probably the most pragmatic way to play this position unless you have something up your sleeve, so to speak.
