I believe the main feature of Panov Attack is the rook lift but untill the h4! move there are way too many ways for Black too deviate...
I tried the Fried Liver sometime ago dont like it. White has nothing after d5 exd5 Na5!
The Parham looks insane.
Against Caro Kann the Panov attack is best! 1.e4-c6 2.d4-d5 3.exd5-cxd5 4.c4!
