Fried liver

I just got ripped apart by this fried liver attack, so I have been studying it in order To be ready for it and probably use it. I found a very long 5 segmented article on the Internet analyzing the lines, and it seems to me that if white knows most of the lines a little more than a double moves in the attacks is full of traps and not too bad afterward even if accurately defended. So, my questions for you guys are these: in orb tournament games if you as white know the lines 14+ moves in how high rated of players could you catch off guard and beat? And, what do players do as black to avoid the attack before it even starts? Thanks in advance for answers!
