Fried Liver Attack

White also has BxN, QxB, Qh5+, Qg6, Qxe5+ and now white is up two pawn and can castle whenever they want to.

The jury is still out on this one, neither side is thought to have the advantage.   In openings like this, it's really the better prepared player will have the advantage

In real CC chess I think white is sometimes afraid to go into it.

In OTB chess I think black is the one who often declines by playing 5...Na5.  If you head for this at a tournament, what you're very likely to see is

No no no, the usual follow up is 7...Ke6 -- white stays down a piece for a long time, but black is in the open.  That's the fried liver attack.

This is basically the starting position.  Here white has tried a few different things I think.

Actually, looking on wiki... wiki basically says what I just said.  I didn't know it was widely accepted that the preference depended on the time control (white is happier in OTB -- black is happier in CC)

Of course White has easier play OTB, and a lot of openings are like that (played in CC but not OTB). However, the Lolli attack, 6.d4, has long been thought to just be better than 6.Nxf7. But Black's Nxd5 is known to be an error...

dude i just posted this ;ike 2 hrs b4 u did but here is a good line:

 Isn't that the name of a movie

Who calls it an error?  It may not be best, but it's certainly not a blunder, it hasn't been refuted yet.

Oh, with the lolli attack maybe.  I don't know much about the opening actually, I only throw out 3.Bc4 in blitz for fun to see where it leads heh.

 I agree I don't think it's a error maybe an inaccuracy but definitely not a mistake.

 its a japanese animated tv series

Black should not play 5. Nd5: but Na5 which gives him a good game.

 There are lots of those.

 Sorry I don't see what you are talking about, can you post it? I've gtg for now but I'll look at it tomorrow.

He's talking about my first diagram where black plays Na5.  Playing against someone who is familiar with their openings, this is what you're likely to run into.

why is stopping your opponent from castling so important?

I play this sometimes against a friend that lives in my apartment building. He can get rattled by an early opening attack. BTW, stopping your opponent from castling means that his/her king is more open to be attacked in the center most of the time.
